Varizen tubal

This Varizen tubal is a continuation of application Ser. The present invention relates generally to a tissue separation cannula used for forming an elongated cavity in tissue planes particularly along the course of a small Varizen tubal vessel, and more specifically relates to Varizen tubal cannula having an endoscope for continuously visualizing the blunt dissection site through a tissue separating member which is transparent and has a tapered shape and Varizen tubal selectively removable from the cannula to facilitate dissection of tissue adjacent a blood vessel.

Varizen tubal methods for the formation of an elongated cavity involve the use of blunt probes that are pushed through body tissue to Varizen tubal the tissue dissection.

The force exerted by the passage of mechanical probes Varizen tubal lead to blood vessel avulsion and trauma to tissue and internal organs.

The problem becomes acute when dissecting and harvesting blood vessels having a small diameter of about 3 to 8 mm. The techniques which are used for dissection of larger blood vessels such as the aorta are not applicable since the aorta is located in the retroperitoneum, Varizen tubal, bounded by the peritoneum on one side and the psoas muscle on the other side. An everting balloon placed in the infrarenal space located just below the kidney will track easily down the length of the aorta along a natural cleavage plane when inflated.

An everting type of balloon encounters difficulties when dissecting tissue adjacent a smaller-diameter vessel. This is due to the presence of less Varizen tubal planes that exist between small diameter blood vessels and the tissue that surrounds these vessels, as compared with the aorta and the tissue that surrounds the aorta, Varizen tubal.

For example, if an everting balloon is placed adjacent to the saphenous vein in the leg, it usually skews dissection upon inflation rather than track along the vein. This is due to the amorphous nature of the fat and connective tissue that surrounds the saphenous vein. Everting balloon catheters are known which are used for Varizen tubal dilation.

See, for example, Varizen tubal, U. Double lumen everting balloon catheters, such as those disclosed in the Fogarty Varizen tubal al. However, an endoscope used in conjunction with those disclosed catheters is unable to monitor the dissection process, Varizen tubal, since the endoscope lies within the central lumen proximal to the everting balloon.

As the balloon everts Varizen tubal the catheter, Varizen tubal, the internal inflation pressure squeezes the walls of the balloon and closes off the distal viewing channel. Also, the area that requires monitoring during balloon dissection is located at the advancing front of the everting balloon, Varizen tubal.

Thus, an endoscope in the central lumen of existing double-lumen, everting balloon catheters is unable to view the area of tissue separation, since a double layer of balloon membrane lies between the endoscope and the tissue and blocks the endoscopic line of sight. This double layer obscures and distorts the viewing area of tissue separation. Endoscopes have been disclosed for use in optical trocars such as in U.

The Nobles et al. Control of the dissection is difficult because visualization of the vessel is obscured by the collapse of the tissue planes into the area between the cutting element and the endoscope. Furthermore, the risk of side vessel avulsion or trauma to the vessel is greatly increased by the orientation of the outwardly extending cutting elements, Varizen tubal.

The endoscope disclosed in Knighton ' has a lateral Varizen tubal of a size sufficient to accommodate the blood vessel being harvested and at least one tool for use in harvesting the blood harvested, Varizen tubal. However, the failure of the endoscope to enlarge a cavity adjacent the blood vessel obscures viewing of the dissection area and manipulation of the vessel therein.

The position of the viewing image relative to the tissue dissection area could obscure the identification of side vessels leading to an increased risk of vessel avulsion, Varizen tubal. Since the vessel is retrieved through the center of the endoscope, all side vessels must be severed for the endoscope to advance and the length of the vessel thus retrieved is limited substantially by the length of the body of the endoscope, Varizen tubal.

An instrument for penetrating body tissue, Varizen tubal, as disclosed in U. An instrument of this type may include a separate illumination channel that ends at the tip for illuminating tissue being penetrated.

The present invention provides a cannula for bluntly dissecting an was Granulierung trophischen Geschwüren cavity in tissue particularly along the course of a vessel in a human or animal body.

The cannula includes a tubular body having proximal closed end and distal blunt end and at least one lumen extending the length of the body. The cannula also includes an endoscope having a lighted, viewing end disposed in the lumen near the distal end of the body, and includes a transparent, Varizen tubal separating member, or blunt tip, Varizen tubal, substantially covering and selectively removable from the distal end of the body.

The tissue separating member or blunt tip disposed on the distal end of the body includes internal walls that taper and end in a sharp point to reduce visual distortion through the endoscope that is optically aligned with the tip, Varizen tubal. A method is also disclosed for bluntly dissecting an elongated cavity particularly along the course of a vessel using a cannula. The method includes the Varizen tubal of: Following dissection of the cavity along the vessel, a counterincision is made at the far end of the cavity, for example, to place a Varizen tubal blunt tip balloon trocar and to allow introduction of dissection instruments.

The tip of the cannula is advanced out of the body through the counterincision, and the tapered tip is detached leaving the cannula body in the dissected cavity. The endoscope resides inside the cannula body, Varizen tubal, and the endoscope and cannula body are selectively positioned as a single unit inside the dissected cavity to facilitate isolating Varizen tubal harvesting the vessel.

The method further may include removing the cannula, then maintaining the elongated cavity using insufflated gas through a balloon cannula that seals the incisions against gas leakage, or using a structural balloon, Varizen tubal, or a mechanical structural support within the dissected cavity.

In another embodiment of the present invention, the method includes the steps of bluntly dissecting an initial cavity; sealing and inflating the cavity; and separating the tissue along the cavity assisted by continuous, visual observation while under inflation until the Ascorbinsäure und Varizen is sufficiently elongated.

The isolated vessel, such as the saphenous vein, Varizen tubal, may be harvested and removed for use as a coronary artery or peripheral vascular bypass graft, or may be left in place as an in-situ femoropopliteal or femoral-distal graft.

The side branches of the vein are ligated, clipped, or occluded in both applications. In the case of an in-situ graft, Varizen tubal, the valves in the vein are disrupted by means of a valvulotome. In accordance with one embodiment of the present invention, a cannula includes a tubular body having proximal closed end and distal blunt Varizen tubal, at least one lumen extending the length of the body, an endoscope having a lighted, viewing end disposed in the lumen near the distal end of Varizen tubal body, and a transparent, tissue Varizen tubal member substantially covering the distal end of the body and selectively removable from the Varizen tubal end.

The present invention also includes methods for using such a cannula for separating tissue to form an elongated cavity along the course of a Varizen tubal blood vessel and subsequently harvesting the blood vessel, or using the blood vessel as an in-situ graft.

The cannula includes a tubular body having a proximal end and a distal end At least one lumen extends the length of the body Disposed in the lumen is an endoscope having a lighted, Varizen tubal, viewing end near the distal end of the body. The other end Varizen tubal the cannula has a proximal end cap and an elastomeric washer that provides a pressure-sealed, sliding fit with the endoscope The cannula also includes a transparent, tissue separating member or blunt tip substantially covering the distal end of the body.

The tissue separating member has a tapered section which angles toward lіkuvannya Varizen Rivne tsіni blunt, tissue-separating tip distal to the distal end of the tubular body.

The shape of the tissue separating member allows atraumatic dissection of a cavity with sufficient control and maneuverability to prevent tearing or puncturing of the nearby vessel, Varizen tubal. Typically, the tip has an outer radius of curvature of about 0. The length of the tapered section of the tip is approximately 0. The tapered shape and blunt tip of the tissue separating member thus allows deflection of branch vessels to Varizen tubal side of the cannula without their avulsion, upon forward advancement of the cannula with reduced requirement of applied axial force to advance the cannula and tip through tissue being dissected.

In tapers of uniform wall thickness with a rounded inner surface near the apex, it has been found that a small circular spot of distortion exists in the center of the visual field of the endoscope, Varizen tubal, equivalent to the diameter of the rounded taper tip. This distortion may be substantially eliminated by forming the transparent taper with an inner profile that Varizen tubal in a sharp point, or apex, while maintaining the outer profile as a rounded tip with approximately a 0.

Undistorted visual imaging through such tip thus allows the surgeon to track down the vessel, identify side branches, and guide the device past the side branches. An optimal taper length of approximately 0.

Alternative embodiments of the present invention include other shapes for the tissue separating member which provide the necessary control and atraumatic dissection. The tissue separating member includes a tapered section integrally formed with a more blunt, Varizen tubal, spherical section at the distal tip of the Varizen tubal separating member.

The tissue separating member includes a curved tapered section integrally formed with a blunt section at the distal tip to form a duck-bill shape. The curved tapered section can have convex or concave shape. The tissue separating member has a hemispherical shape covering the distal end Preferably, Varizen tubal, the tissue separating membershave an Varizen tubal length of about 0.

The wall thickness of the tissue separating member may be contoured to form a lens for special applications that require a magnified or otherwise distorted image, e. Suitable materials for making the tissue separating member or blunt tip include polycarbonate and any material which is sufficiently strong to separate tissue and sufficiently transparent to allow visualization by the endoscope.

As illustrated in FIGS. Referring again to FIG. The balloon may be elastic or inelastic, although an elastomeric Varizen tubal is preferred because it achieves a smaller, Varizen tubal, smoother outer profile. Fully inflated as shown in phantom in FIGS. Preferably, a sleeve type of balloon has both the distal end and proximal end of the balloon secured to the exterior wall of the cannula. The balloon is selectively inflated by supplying thereto via another lumen a pressurized fluid, such as a gas or liquid, from an inflation port to a hole in the exterior wall of the cannula between the proximal and distal endsVarizen tubal, of the balloon to communicate with the interior thereof.

A plunger device, such as a manually-operated syringe, Varizen tubal, is suitable for connecting at the inflation port to control the inflation of the balloon The lumen is formed as another tubular body in a concentric arrangement with the body to form a space between the two bodies.

Another embodiment suitable of the present invention may include two lumensin a side-by-side arrangement. Additional lumens can be added in similar manner to provide other functions such as irrigation and aspiration in known manner. Varizen tubal present invention is illustrated using a sleeve type of balloon Varizen tubal the cannula Other balloon types are suitable for use with the present invention such as, and not limited to, using an invertable balloon positioned in a separate lumen in the cannula to assist in separating the tissue when inflated.

The cannula may be manufactured from a variety of bioinert, substantially inelastic Varizen tubal, such as stainless steel, polyethylene, Varizen tubal, polyurethane, polyvinyl chloride, polyimide plastic, and the like that preferably have a tensile strength of at least 10, psi, Varizen tubal.

Preferably, each lumen of the cannula has a wall thickness of between about 0. The endoscope has an outer diameter of approximately 5. The endoscope is positioned within the lumen with the tip in correct position to allow unimpeded visualization through the transparent blunt tip of the surrounding tissue and vessel outside of the cannula A preferred endoscope having a tubular diameter of about 5. Methods Varizen tubal bluntly dissecting an elongated cavity using the cannula of the present invention are shown in the flow diagrams of FIGS.

Although the blunt dissection of an elongated cavity along the course of a vessel is specifically described, the Varizen tubal invention is generally suitable for separating any tissue. For example, the cannula may be used to track along the median nerve from an incision at the patient's wrist, forming a cavity for surgical treatment of carpal tunnel syndrome. The cannula allows visualization and tracking of the median nerve, preventing the injury to Varizen tubal nerve which may occur if blind advancement of a balloon cannula were used.

Alternatively, the cannula of the present invention may also be used to dissect a cavity adjacent the mammary artery in the manner as later described herein. The method illustrated in the flow diagram of FIG. Blunt dissection is performed to separate the vessel from adjacent tissue for a length of approximately 1 to 2 cm. The blunt dissection may be performed Varizen tubal a pair of curved Metzenbaum scissors, using the tips of Varizen tubal scissors to cut and bluntly spread tissue in a plane between the vessel and the adjacent tissue.

Preferably, a blunt tip balloon cannula is introduced into the space between the vessel and the overlying tissue, Varizen tubal. The balloon is then inflated to form a gastight seal which seals the dissection. A gas such as carbon dioxide is infused under pressure via another lumen in the cannula having an external opening positioned distal to the balloon. The natural perivascular plane around the vessel is expanded by the injected gas, forming a tract along the course of the vessel, Varizen tubal.

For a superficial vessel such as the saphenous vein, the expanded tract is visible on the surface of the skin. The interior of the expanded tract is not cleanly open but rather, includes gossamer-like strands of connective tissue and fat, preventing unobstructed visualization and making hazardous the passage of an endoscope along the tract adjacent to the vessel.

If a conventional endoscope is pushed into this connective tissue in an attempt to form a cavity adjacent to the vessel, the view through the conventional endoscope is blurred by the tissue that contacts the viewing end of the conventional endoscope.
