    Abstract: 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.

    Abstract: 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.

    Abstract: A stent having an elongate tubular configuration is formed of a plurality of elongate elements interwoven or braided to form a tubular configuration. The elements may be relatively strong and rigid, but movable relative to each other within the weave or braid in order to provide the stent with generally soft characteristics. The elements may be formed of different materials, such as an absorbent material permitting the stent to be doped with materials such as drugs and chemicals. Even the absorbency can be controlled and varied to provide a predetermined time-release of the absorbent.

    Abstract: An access device has a distal, expandable member with a low-profile state facilitating insertion and a high-profile state facilitating operation of the device. An obturator can be used to move the expandable member between its two states. Alternatively, the device can have an outer tube and an inner tube connected to respective ends of a cylindrical expansion member, so that co-axial movement of the tubes changes the state of the member. An actuator slideable on a handle facilitates the co-axial movement of the tubes, and a resulting formation of the expandable member in a funnel configuration.

    Abstract: An access system comprises an access device. The access device is adapted to be disposed within an opening in a body wall. The access device has an external flange adapted to be disposed external to the body wall and an internal flange adapted to be disposed internal to the body wall. Holes extend through the access device between an external surface and an internal surface of the access device. The holes span the thickness of the body wall between a location external to the body wall and a location internal to the body wall. The access device is formed of an elastomeric material adapted to conform to surfaces of instruments inserted through the holes to form instrument seals along at least a portion of a length spanning the thickness of the body wall. The elastomeric material is compressible and adapted to form a seal with the body wall.

    Abstract: Methods and apparatus for securing and deploying tissue anchors are described herein. A tissue manipulation assembly is pivotably coupled to the distal end of a tubular member. A reconfigurable launch tube is also pivotably coupled to the tissue manipulation assembly, which may be advanced through a shape-lockable endoscopic device, a conventional endoscope, or directly by itself into a patient. A second tool can be used in combination with the tissue manipulation assembly to engage tissue and manipulate the tissue in conjunction with the tissue manipulation assembly. A deployment assembly is provided for securing engaged tissue via one or more tissue anchors, the deployment assembly also being configured to disengage the anchors endoluminally or laparoscopically by applying thermal energy through at least one suture cutting element disposed along the deployment assembly.
