    摘要: Apparatus & methods for endoscopic suturing are described herein. A distal tip of the endoscopic device engages the tissue and then approximates the engaged tissue to form a tissue fold. A needle body positioned within a flexible catheter is deployed into or through the newly created tissue fold where it is then detached or released from the endoscopic device. The needle body has a length of suture which depends therefrom and can be used to secure the tissue fold. The entire endoscopic device or its tissue engaging assembly can then be rotated relative to the tissue fold while maintaining engagement with the tissue to maneuver the flexible catheter to the opposing side of the penetrated tissue fold. This procedure can be repeated any number of times to create an interrupted, continuous, or running suture to secure the tissue fold.

    摘要: Apparatus and methods are provided for placing and advancing a diagnostic or therapeutic instrument in a hollow body organ of a tortuous or unsupported anatomy, comprising a handle, an overtube, a distal region having an atraumatic tip. The overtube may be removable from the handle, and have a longitudinal axis disposed at an angle relative to the handle. The overtube may be selectively stiffened to reduce distension of the organ caused by advancement of the diagnostic or therapeutic instrument. The distal region permits passive steering of the overtube caused by deflection of the diagnostic or therapeutic instrument while the atraumatic tip prevents the wall of the organ from becoming caught or pinched during manipulation of the diagnostic or therapeutic instrument.

    摘要: 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.

    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.
