摘要： The invention is directed to a trocar adapted to form a seal around a surgical instrument, the trocar comprising a cannula having an axis extending between a proximal end and a distal end; a housing having a proximal wall and forming with the cannula a working channel sized and configured to receive the instrument; a septum seal disposed in the housing and extending transverse to the axis of the cannula across the working channel, the septum seal having a normal state when the instrument is absent from the working channel and a stretched state when the instrument is being withdrawn from the working channel; portions of the proximal wall of the housing defining an orifice sized and configured to receive the instrument into the working channel; and an elastomeric ring-shaped projection extending axially distally between the proximal wall and the septum seal, the ring-shaped projection having an axial length adapted to deform to prevent inversion and binding of the septum seal and the orifice upon withdrawal of the surgical instrument. In particular, the septum seal is prevented from reaching the orifice in the proximal wall of the housing when the instrument is withdrawn. The projection may be bonded, insert-molded, or compressively fitted to the proximal wall of the housing. The projection may be formed of an elastomeric material such as natural or synthetic rubber. The projection may further comprise a plurality of portions or fingers extending axially distally from the proximal wall, each of the extending portions or fingers may further include a living hinge. In another aspect, the ring-shaped projection may be formed on the surface of the septum seal instead of the proximal wall of the housing. That is, the ring-shaped projection may be formed to extend axially proximally from the surface of the septum seal toward the proximal wall of the housing.

摘要： A surgical wound retractor is adapted to dilate a wound stretchable to a desired diameter, the retractor includes a first ring having a diameter greater than that desired for the wound and being adapted for disposition interiorly of the wound. A second ring has a diameter greater than that desired for the wound and is adapted for disposition exteriorly of the wound. A plurality of retraction elements are disposed in a generally cylindrical relationship to each other, between the first ring and the second ring. These elements extend through the wound to exert a radial retraction force on the wound which is dependent on the distance separating the first ring and the second ring. Retraction elements, both distensible and non-distensible are contemplated with appropriate attachment means at the rings to provide for variations in the retraction force. With a suitable retraction sleeve, a third ring can be provided to form a circumferential retainer to vary the retraction force. Rings can also be made inflatable or self-expanding to vary the retraction force. An associated method includes the step of rolling the second ring circumferentially of the third ring to form the circumferential retainer.

摘要： A surgical access device, such as a trocar, includes a pendent valve having an elongate structure extending from a proximal end to a septum valve disposed at a distal end. In operation, the elongate structure follows the angle of the instrument to pre-position the septum valve into the path of the instrument where it is not significantly challenged during instrument insertion or manipulation. The pendant valve can be made to float at both the proximal end and the distal end of the elongate structure, to further reduce the vulnerability of the septum valve. Since the valve is less vulnerable to instrument insertion, it can be formed to minimize friction and maximize the functional range of the access device.

摘要： A releasable mechanism such as a cap is adapted for use with an access sheath having an elongate tube and a handle structure disposed at a proximal end of the tube. The releasable mechanism is sized and configured to fit the handle structure, which is shaped like the bell of a horn, to further facilitate use with surgical instrumentation. The releasable mechanism may operate as a separate cap that snaps onto the handle structure to provide access pathways to the sheath. The releasable mechanism may also be disposed at a proximal end of a surgical instrument to be introduced into the access sheath such that it may be interlocked with the sheath. In a method of manufacturing a kink-resistant sheath, a wire is initially coated with a plastic material, the coated wire is then wrapped around a mandrel forming a plurality of windings, and the wound coated wire is heated until the plastic material melts and bonds the windings to form a wire-reinforced sheath. The plastic material is preferably polyurethane but may be a thermoplastic, a thermoset or any plastic material having hard and/or soft durometer. The wound coated wire may be heated by capturing the windings within a shrink tube or compressing the windings in a mold and heating the windings until the sheath is formed. In another aspect of the invention, a mandrel is used as part of an extrusion process. In another aspect of the invention, another coating or outside layer could be formed over the spring reinforcement by dipping in a solvent based solution. In yet another embodiment of the invention, a braid such as a polyester braid may be used instead of or in addition to the coil spring to form a kink-resistant sheath.

摘要： A catheter adapted to increase the patency of a body conduit includes an elongate tube having an axis extending between a proximal end and a distal end, and a balloon disposed at the distal end of the tube and having properties for being expanded to a high-profile state and for being contracted to a low-profile state. A sleeve disposed over the balloon has a pair of ends disposed on opposing sides of a central section, the ends having a floating relationship relative to the tube with the central section disposed circumferentially of the balloon. An electrode disposed outwardly of the sleeve has properties for being electrosurgically energized to incise materials defining the body conduit when the balloon is in the high-profile state. The electrode can be formed of a plurality of elements stranded to increase the surface area of the electrode. The catheter can be inserted relative to a guide member having a conductor which carries the electrosurgical energy from the proximal end of the tube to the electrode at the distal end of the tube. An associated method includes the step of introducing electrosurgical energy into the conductor of the guide member to energize the electrode of the catheter.

摘要： A suturing apparatus adapted to close an incision and an anterior tissue wall includes an elongate support structure having an axis extending between a proximal end and distal end. A receiver disposed at the distal end is insertable through the incision in a low-profile state and expanded to a high-profile state on the far side of the tissue wall. Needles carried by the support structure are operable to extend through the support wall on either side of the incision and into the expanded receiver. Sutures advanced through the needles are captured by the receiver after the needles are removed and the receiver is returned to its low-profile state. Removal of the suturing apparatus from the incision draws the captured suture ends outwardly through the incision. A novel suture knot can be tied in the four suture ends and moved into proximity with the tissue wall to close the incision.
