Patent ID: 8016745

Claim:
A system for obtaining data from an implanted device, the system comprising: (a) an implantable restriction forming device, wherein the implantable restriction forming device is operable to form a restriction in a patient, wherein the implantable restriction forming device comprises an implantable injection port, wherein the implantable injection port defines a fluid reservoir in fluid communication with the implantable restriction forming device, wherein the fluid reservoir of the implantable injection port is configured to receive a fluid, wherein the implantable injection port includes a needle penetrable septum configured to receive a needle for adding fluid to or withdrawing fluid from the fluid reservoir via the needle; (b) an implantable pressure sensor positioned within the implantable injection port of the implantable restriction forming device, wherein the implantable pressure sensor comprises a diaphragm in fluid communication with the fluid reservoir of the implantable injection port and one or more strain gauges connected with the diaphragm, wherein the one or more strain gauges are configured to sense strain in the diaphragm as a function of the pressure of the fluid such that the implantable pressure sensor is operable to sense the pressure of fluid in the fluid reservoir; (c) one or more implantable communicators in communication with the implantable pressure sensor, wherein the one or more implantable communicators are operable to communicate data from within a patient; (d) one or more external communicators in communication with the one or more implantable communicators, wherein the one or more external communicators are operable to externally receive data communicated from within a patient by the one or more implantable communicators; and (e) a storage device in communication with the one or more external communicators, wherein the storage device is operable to store at least a portion of data received by the one or more external communicators.
