1. A method of control of a gastrointestinal tract, or a portion thereof, the gastrointestinal tract, or portion thereof, comprising a pylorus, the method comprising the steps of:
- electrically stimulating patches in the vicinity of the pylorus until the pylorus relaxes; and
applying electrical energy to the gastrointestinal tract or a portion thereof to invoke a desired motility response of the gastrointestinal tract.

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.

19. Apparatus for control of gastrointestinal motility, the apparatus compnsing:
-
an implant incorporating gastrointestinal tract electrodes; and a controller for delivering energy to the gastrointestinal tract electrodes, the controller being configured to deliver a first electrical pattern to the electrodes to cause a muscle of the gastrointestinal tract to relax after a prolonged controlled contraction, and a second electrical pattern to the electrodes to cause a desired response of the gastrointestinal tract. - View Dependent Claims (20)
