Abstract

Methods and devices to externally create a restriction on the stomach are described. The devices are contoured to fit the stomach and can be further anchored to the stomach. The degree of deployment of the extragastric restriction device is controllable after implantation. Specialized wires, catheters, ports, and trocars specific for placement of extragastric restriction devices are presented. Systems are described in which adjustability of the devices is provided along with sensing and actuating ability.

Claims

1. An implantable device for treatment of obesity, said device comprising:

an expandable, inflatable main body member configured to be positioned adjacent a portion of a stomach of a patient wherein said inflatable member comprises two different materials at two different portions thereof, wherein a first of said materials is more compliant than a second of said materials;

an anchor configured to fix a portion of said main body member to the abdominal wall;

an adjustment member having a port, said adjustment member configured to be anchored to an abdominal wall or subcutaneously external to the abdominal wall; and

a conduit connecting said main body with said adjustment member.

2. An implantable device for treatment of obesity, said device comprising:

an expandable, inflatable main body member configured to be positioned adjacent a portion of a stomach of a patient wherein said inflatable member comprises two different materials at two different portions thereof, wherein a first of said materials is more compliant than a second of said materials;

an anchor configured to fix a portion of said main body member to the abdominal wall wherein said anchor at least partially comprises a surgical mesh material;

an adjustment member having a port, said adjustment member configured to be anchored to an abdominal wall or subcutaneously external to the abdominal wall; and

a conduit connecting said main body with said adjustment member.

3. An implantable device for treatment of obesity, said device comprising:

an expandable, inflatable main body member configured to be positioned adjacent a portion of a stomach of a patient wherein said inflatable member comprises two different materials at two different portions thereof, wherein a first of said materials is more compliant than a second of said materials and wherein said second material comprises a surgical mesh material configured to fix a portion of said main body member to the abdominal wall;

an adjustment member having a port, said adjustment member configured to be anchored to an abdominal wall or subcutaneously external to the abdominal wall; and

a conduit connecting said main body with said adjustment member.
