Management systems for the surgically treated obese patient
First Claim
1. A fluid access port with a proximal end and a distal end, the proximal end operable to be accessed for fluid injection and the distal end operable to receive fluid and deliver it to a fluid receiving structure in a patient, the fluid access port comprising:
- a. A pressure sensing system constructed wherein the pressure sensing system is hydraulically coupled to the fluid access port and wherein the pressure sensing system comprises;
i. A pressure sensor;
ii. A circuit operable to receive a pressure related signal from the pressure sensor and generate an output signal;
and, wherein the pressure sensing system is reversibly attachable to the fluid access port when the fluid access port is implanted in a patient and the pressure sensing system is external to the patient.

Abstract
In one embodiment, a pressure sensing system is described which transmits data to a patient management system external to a patient. The pressure sensing system can rigidly couple to an implantable port or flexibly couple to an implantable port. In some embodiments, the pressure sensing system communicates with a hydraulic actuating system. In some embodiments, the pressure sensing system is implantable and comprises a circuit capable of wireless transmission through the skin of a patient to an external receiver which is part of a patient management system. A patient management system is described which receives up to date as well as historical data from the pressure sensing system and manages the these data in the context of a patient database.
