Filed:

Mar 29, 2000

Appl. No.:

09/538863

Inventors:

David E. Silverman - Palo Alto CA
Alan Stein - Moss Beach CA
Edward J. Gough - San Carlos CA

Assignee:

Enteric Medical Technologies, Inc. - Foster City CA

International Classification:

A61F 200

US Classification:

600 29

Abstract:

An apparatus comprising an elongate probe member having proximal and distal extremities for use with a suction source to treat a portion of a wall forming a cavity in a body having a natural body opening for accessing the cavity. The elongate probe member has a length so that when the distal extremity is in the vicinity of the portion of the wall the proximal extremity is outside of the body. The distal extremity of the elongate probe member has an outer surface and is provided with at least one recess opening onto the outer surface and an internal passageway communicating with the recess. When the suction source is coupled to the apparatus a suction is created in the recess by means of the passageway to draw the portion of the wall into the recess. A hollow needle is slidably disposed in the elongate probe member and has a distal end portion. The needle is actuatable from outside the body for movement from a retracted position in which the distal end portion of the needle is out of the recess and an extended position in which the distal end portion of the needle extends into the recess.

International Classification:

A61B 1818

US Classification:

606 42, 606 41, 607101, 607105

Abstract:

An ablation apparatus includes a handpiece, an electrode extending from a handpiece distal end, a probe, a thermal sensor and an energy source. The electrode includes a distal end and a lumen, a cooling medium inlet conduit and a cooling medium exit conduit. Both conduits extend through the electrode lumen to an electrode distal end. A sidewall port, isolated from a cooling medium flowing in the inlet and outlet conduits, is formed in the electrode. The probe is at least partially positionable in the electrode lumen and configured to be advanced and retracted in and out of the sidewall aperture. The thermal sensor is supported by the probe. The electrode is coupled to an energy source.

International Classification:

A61F 200

US Classification:

600 29

Abstract:

A method for treating a blood vessel in a wall forming a gastrointestinal tract of a body of a mammal. At least one nonaqueous solution is introduced from the gastrointestinal tract into the vessel. A nonbiodegradable solid is formed in the vessel in the vicinity of a portion of the vessel from the least one nonaqueous solution to create an occlusion in the vessel and thus terminate blood flow to the vessel distal of the occlusion.

International Classification:

A61F 200

US Classification:

600 29

Abstract:

A method for forming a valve-like mechanism in a body of a mammal having an esophagus extending through a lower esophageal sphincter to a stomach and formed by a wall having a muscle layer and a mucosal layer. The method comprises the step of forming at least one implant in the muscle layer of the wall in the vicinity of the lower esophageal sphincter. The at least one implant inhibits opening of esophagus at the lower esophageal sphincter and causes the mucosal layer to appose in the vicinity of the implants.
