Abstract
A restriction system, such as an adjustable gastric band, for forming a restriction in a patient and non-invasively communicating pressure data regarding the restriction to an external monitor. The system includes a restriction device for implantation in a patient to form a restriction. The system further includes an implanted port connected to the restriction device. The port contains a working fluid for affecting the size of the restriction. The system further includes a pressure sensing system in communication with the working fluid for measuring the pressure of the working fluid and transmitting pressure measurement data to an external monitor.
Claims19
A restriction system for forming a restriction in a patient and non-invasively communicating pressure data regarding the restriction to an external monitor, the system comprising:
- a. a restriction device for implantation in a patient to form a restriction therein;
- b. an implanted port connected to said restriction device, said port containing a working fluid for affecting the size of the restriction;
- and
- c. a pressure sensing system in communication with said working fluid for measuring the pressure of said working fluid and transmitting pressure measurement data to an external monitor.
A restriction system for forming a restriction in a patient and non-invasively communicating pressure data regarding the restriction to an external monitor, the system comprising:
- a. a restriction device for implantation in a patient to form a restriction therein, said restriction member having a variable fluid volume for creating a restriction;
- b. a control operatively connected to said restriction member for varying the volume of said restriction member;
- and
- c. a pressure sensing system for measuring fluid pressure within said restriction member and non-invasively communicating the measured pressure to said external monitor, the measured pressure being proportional to the degree of restriction formed in the stomach.
