System for controlling a controllable stomach band
First Claim
1. A control system for controlling a controllable gastric band (1), comprising a control unit (11), wherein the gastric band (1) includes a non-extensible back (4) and a chamber (2) arranged on a stoma side of the back (4) and capable of being filled with a fluid, said chamber being in connection with a second chamber (5) and having at least one sensor (7) to detect pressure values on the gastric wall (3), and wherein the at least one sensor (7) is connected with a transmission device (8) for wireless transmission of the detected pressure values to the control unit (11), and wherein the control unit (11) includes a receiving device (13) for receiving the pressure values transmitted from the at least one sensor (7) of the gastric band (1), as well as a housing (12), wherein the system comprises a memory for storing a time course of pressure values, wherein the time course comprises pressure values detected by the at least one sensor (7) over a period of time and recorded as a function of time, and a processing device (16) configured to evaluate amplitudes and durations of increases in the pressure values in the stored time course, wherein the increases correspond to primary and secondary peristaltic waves in the esophagus of a patient in whom the gastric band is implanted so as to enable automatic control of the gastric band based on the evaluated amplitudes and durations.

Abstract
A system for controlling a controllable gastric band (1), having a control unit (11), wherein the gastric band (1) includes a nonextensible back (4) and a chamber (2) arranged on the stoma side of the back and capable of being filled with a fluid, which chamber is in connection with a second chamber (5) and has at least one sensor (7) for the detection of the pressure on the gastric wall. The sensor (7) can be connected with a device (8) for the wireless transmission of the detected pressure values to the control unit (11). The control unit (11) can include a device (13) for receiving transmitted pressure data from the at least one sensor (7). Also, at least one memory (9, 14) for storing the pressure values detected and a device (16) for processing the time courses of the pressure values detected.

28. A system for controlling a controllable gastric band, wherein said gastric band includes a non-extensible back, a first chamber arranged on a stoma side of the back, wherein said first chamber is capable of being filled with a fluid, and a second chamber
connected to the first chamber, the system comprising: -
(a) at least one pressure sensor disposed in the first chamber of the gastric band to detect pressure values on the gastric wall; (b) a memory for storing a time course of pressure values, wherein the time course comprises pressure values detected by the at least one pressure sensor over a period of time; (c) a transmission device connected with the at least one pressure sensor for wireless transmission of pressure values; (d) a control unit comprising a housing and a receiving device for receiving pressure values transmitted from the transmission device; and (e) a processing device configured to evaluate amplitudes and durations of increases in time courses of pressure values, wherein the increases correspond to primary and secondary peristaltic waves in the esophagus of a patient in whom the gastric band is implanted.
