Abstract
A method and a multichannel implantable device are described for partial or complete restoration of impaired gastrointestinal motility, or for disturbing and/or partially or completely blocking normal gastrointestinal motility using one or multiple microsystem-controlled channels of circumferentially arranged sets of two or more electrodes which provide externally-invoked synchronized electrical signals to the smooth muscles via the neural pathways.
Claims12
An apparatus for controlling gastrointestinal motility, comprising:
- one or more sets of electrodes circumferentially arranged about a patient's gastrointestinal tract;
- and
- a controller adapted to deliver electrical stimulation to the one or more sets of electrodes to at least partially block normal gastrointestinal motility of at a least a portion of the patient's gastrointestinal tract to delay gastric emptying.
An apparatus for controlling gastrointestinal motility, comprising:
- one or more sets of electrodes circumferentially arranged about a first portion of a gastrointestinal tract;
- and
- a controller adapted to deliver electrical stimulation to the one or more sets of electrodes to induce a local circumferential contraction in the first portion of the gastrointestinal tract asynchronously with intrinsic electrical activity of the gastrointestinal tract to delay emptying of the stomach.
A method to control motility of a gastrointestinal tract, comprising:
- applying electrical stimulation to one or more sets of electrodes circumferentially arranged about a gastrointestinal tract to at least partially interrupt normal gastrointestinal motility of at least a portion of the gastrointestinal tract to delay gastric emptying.
A method to control motility of a gastrointestinal tract, comprising:
- applying electrical stimulation to one or more sets of electrodes circumferentially arranged about a gastrointestinal tract to induce a local circumferential contraction in the gastrointestinal tract asynchronously with intrinsic electrical activity of the gastrointestinal tract to delay emptying of the stomach.
