Non-invasive pressure measurement in a fluid adjustable restrictive device
First Claim
1. A restriction system for forming a restriction in a patient, the system comprising:
- (a) an implantable restriction device, wherein the implantable restriction device is operable to form a restriction in a patient;
(b) an implantable port in fluid communication with the implantable restriction device, wherein the implantable port is configured to receive fluid from a fluid source external to the patient, wherein the implantable port comprises a needle penetrable septum and a housing, wherein the septum is configured to receive a needle for injection of fluid into the port or withdrawal of fluid from the port;
(c) an implantable fluid conduit positioned between the implantable restriction device and the implantable port, wherein the implantable conduit is configured to permit communication of fluid from the implantable port toward the implantable restriction device, wherein the implantable conduit is further configured to permit communication of fluid from the implantable restriction device toward the implantable port;
(d) a fluid, wherein the fluid is located within each of the implantable restriction device, the implantable port, and the implantable fluid conduit;
(e) a first implantable pressure sensor, wherein the first implantable pressure sensor is in fluid communication with the fluid and positioned within the implantable port, wherein the first implantable pressure sensor is operable to sense the pressure of the fluid within the implantable port, wherein the first implantable pressure sensor is further operable to communicate pressure data to an external monitor; and
(f) a second implantable pressure sensor, wherein the second implantable pressure sensor is located in one of the implantable fluid conduit or the implantable restriction device.

Abstract
An implantable restriction device is configured to provide a restriction in a patient as a function of the pressure of fluid. The implantable restriction device includes one or more pressure sensors configured to sense pressure of the fluid within the implantable restriction device. Pressure data obtained by the one or more pressure sensors may be communicated to a device located external to the patient, which may process the pressure data, and may further provide a display to a user including information relating to the processed pressure data. Where the implantable restriction device comprises an adjustable gastric band, the one or more pressure sensors may be located in any number of the following locations: an injection port, an interface between the injection port and a catheter, in a catheter, in-line with a catheter, adjacent to a catheter, in a gastric band, in a gastric band buckle, or elsewhere.
