Filed:

Jul 19, 2001

Appl. No.:

09/910439

Inventors:

Camran Nezhat - Woodside CA
Andrew H. Hancock - Fremont CA
Alan Bachman - New Haven CT

Assignee:

Perfect Surgical Techniques, Inc. - Palo Alto CA

International Classification:

A61B 1818

US Classification:

606 48, 606 51, 606 50

Abstract:

A bipolar surgical device comprises a pair of actuable jaws. A first electrode member which optionally includes a line of electrically coupled tissue-penetrating elements is formed on one of the jaws, and a second electrode member which optionally includes a line of electrically coupled tissue-penetrating elements is formed on the same or the other jaw. The electrode members are laterally spaced-apart and arranged in a parallel, usually linear manner so that the lateral distance therebetween remains generally constant. In operation, tissue may be grasped between the jaws so that the electrode members contact and/or the tissue-penetrating elements enter into the tissue. By energizing the electrode members at opposite polarities using a high frequency energy source, tissue between the jaws will be heated, coagulated, and/or necrosed, while heating of tissue outside of the lines will be minimized.

International Classification:

A61B 17/08

US Classification:

606153, 606142, 2271751

Abstract:

A system for tissue approximation and fixation is described herein. The devices are advanced in a minimally invasive manner within a patient's body to create one or several divisions or plications within a hollow body organ. The system comprises a tissue acquisition and folding device and a tissue stapling or fixation device, each of which is used together as a system. The acquisition device is used to approximate tissue regions from within the hollow body organ and the stapling device is advanced through a main lumen defined through the acquisition device and is used to affix the approximated tissue. The stapling device is keyed to maintain its rotational orientation relative to the acquisition device as well as to provide the user positional information of the stapling device. The acquisition device is also configured to provide lateral stability to the stapling device prior to the stapling device being clamped onto tissue.

US Classification:

2271751

Abstract:

A single fold system for tissue approximation and fixation is described herein. The devices are advanced in a minimally invasive manner within a patient's body to create at least one fold within a hollow body organ. The system comprises a tissue acquisition and folding device and a tissue stapling or fixation device, each of which is used together as a system. The acquisition device is used to approximate a single fold of tissue from within the hollow body organ and the stapling device is advanced through a main lumen defined through the acquisition device and is used to affix the tissue. The stapling device is keyed to maintain its rotational orientation relative to the acquisition device and to provide the user positional information of the stapling device. The acquisition device is also configured to provide lateral stability to the stapling device prior to the stapling device being clamped onto tissue.

Abstract:

A system for tissue approximation and fixation is described herein. A device is advanced in a minimally invasive manner within a patient's body to create one or several divisions or plications within a hollow body organ. The system comprises a stapler assembly having a tissue acquisition member and a tissue fixation member. The stapler assembly approximates tissue from within the hollow body organ with the acquisition member and then affixes the approximated tissue with the fixation member. In one method, the system can be used as a secondary procedure to reduce the size of a stoma within the hollow body organ.

International Classification:

A61B 1/32

US Classification:

600206, 606153, 606151

Abstract:

A medical device for managing tissue in an organ, such as the stomach, for retracting or positioning tissue and related organs to allow certain regions of the stomach to be acquired for a gastroplasty procedure. The medical device includes an elongated body having a proximal end and a distal end, and a tissue treatment device attached to the distal end of the elongated body. The tissue treatment device includes a first jaw opposite a second jaw, and each jaw is adapted to acquire tissue. A retractor is disposed along the tissue treatment device and adapted to be moveable from a delivery position to a retraction position to move or manage the tissue of the stomach. The medical device also includes a collapsible barrier disposed between the first and second jaws of the tissue treatment device to direct tissue into the first and second jaws separately.
