International Classification:

A61B 1704

US Classification:

606142, 606151, 606157

Abstract:

A system and method for delivering a surgical clip to a surgical site within a patients body to compress body tissue is disclosed. In one embodiment for the system of the present invention, the system includes an endoscopic device that has an endoscope cap disposed on a distal end of the endoscopic device. A surgical clip is removably disposed on an outside surface of the endoscope cap. A deployment device is associated with the surgical clip for deploying the surgical clip from the endoscope cap to the body tissue that is to be compressed.

US Classification:

606 45, 606 41, 606 40, 606 39, 606 48, 606 49, 606 50

Abstract:

An integrated catheter assembly for enabling diverse endoscopic in situ therapies. The assembly includes a catheter with an irrigation fluid lumen, a distal electrode tip portion that acts as a hemostat, and a cutting wire for making incisions in or ablating tissue. A cutting wire hub provides a sealing entrance for a cutting wire. An operator enables the physician to displace the cutting wire between extended and retracted positions. The cutting wire and electrode are electrically isolated. In addition, the catheter assembly may include a planar tip which, when extended outside the distal end of the assembly, assumes a substantially flat unbiased configuration for use. The apparatus of the present invention allows the physician to make incisions in or ablate tissue using electrosurgery, irrigate tissue, and cauterize or coagulate tissue without having to remove the apparatus from the working channel of the endoscope.

International Classification:

A61B 1900

US Classification:

128898

Abstract:

A system for placing an implant in the body includes an elongated member having at least one inner lumen extending from a proximal end portion of the member to an opening in a distal end portion of the member. At least one compressible implant is in the inner lumen of the member. The implant optionally includes anchor members projecting from its outer surface to limit migration of the implant in the body. Structure is provided to push the implant through the opening in the distal end portion of the member. The implant is placed between layers of body tissue to bulk the tissue. In one of the disclosed methods, the system is used to treat gastroesophageal reflux disease (GERD) by placing the implant between layers of body tissue at or near the gastroesophageal junction.

International Classification:

A61B 1818

US Classification:

606 41, 606 50

Abstract:

A multi-function surgical instrument is disclosed. In accordance with an embodiment of the present invention, the surgical instrument includes a catheter, a bipolar hemostat assembly, an attachment member, and a surgical tool. The bipolar hemostat assembly includes an electrical connector at a proximal end, a bipolar electrode assembly at a distal end, and first and second electrical leads extending from the proximal end to the distal end and disposed within the catheter. The bipolar electrode assembly includes an aperture that extends axially therethrough. The attachment member is disposed within the catheter and has a proximal end and a distal end where the distal end is movable within the aperture of the bipolar electrode assembly between a first position wherein the distal end is extended from the bipolar electrode assembly and a second position wherein the distal end is retracted within the bipolar electrode assembly. The surgical tool is attached to the distal end of the attachment member.

US Classification:

606 47, 606167, 604 22, 128898

Abstract:

The present invention provides an apparatus for, and a method of, accurate positioning of endoscopic instruments. Accurate positioning of the instruments is accomplished through the inclusion of a steering ability within the device. After the endoscopic instrument is properly positioned the present invention may use rapid exchange technology, soft locks, and mechanical locks to maintain the position of the endoscopic instrument. Rapid exchange technology is used to minimize displacement forces present on the guidewire or catheters. Soft locks and mechanical locks resist movements caused by displacement forces.
