Apparatus and methods for control of body lumens
First Claim
1. An implantable system for selectively opening and closing a body lumen, said system comprising:
- a control module including a power source and a remotely operated switch which controls an output from the power source to produce a pressurized inflation medium; and
an actuator comprising an inflation cuff connectable to receive the pressurized inflation medium from the output on the control module, wherein said cuff is mountable over an exterior of the body lumen and shifts between an open configuration where the body lumen is at least partially open and a closed configuration where the body lumen is closed in response to a change in power from the output controlled by the switch.

Abstract
Implantable systems for controlling flow through body lumens comprise a control module and an actuator. The actuator is implanted at least partially over the body lumen to selectively constrict the lumen and control flow therethrough. The control module includes at least a power source for operating the actuator and a remotely operated switch for controlling the power source. Usually, the control module will have programmable circuitry for adjusting on/off time, degree of closure, and the like. The switch of the control module is remotely actuated by a magnetic or other signal. The control circuitry may be remotely programmed using a hand-held programmer.

13. An implantable system for selectively opening and closing a body lumen, said system comprising:
-
a control module including a power source, a remotely operated switch which controls an output from the power source and a remotely programmable component which modulates at least one variable selected from the group consisting of opening time, opening diameter, opening force, and closing force; an actuator connectable to receive power from the output on the control module, wherein said actuator couples to an exterior of the body lumen and shifts between an open configuration where the body lumen is at least partially open and a closed configuration where the body lumen is closed in response to a change in power from the output controlled by the switch; a remote switch actuator for turning the power source on and off in the control module; and a remote programmer which can download program information to the remotely programmable component of the control module. - View Dependent Claims (14, 15, 16, 17, 18, 19)
