1. An implantable device for stimulating the smooth muscles or nerves inside the body, comprising:
- a stimulating electrode;
a stimulator for generating pulses and delivering the generated pulses to said smooth muscles or nerve through the stimulating electrode;
an anchoring unit, having a base, attached to said stimulator, wherein said anchoring unit has a pre-deployment shape and a post deployment shape, wherein said post deployment shape is different than the pre-deployment shape, wherein said anchoring unit is capable of anchoring said stimulator to an implant site proximate to said smooth muscles or nerve, and wherein said anchoring unit is capable of puncturing a wall of an organ at a puncture site, wherein said anchoring unit is capable of foreshortening upon deployment of said device in the wall of an organ to pull the device deeper into said wall of the organ, and wherein, upon being pulled deeper into said wall, the base of said anchoring unit is adapted to seal said puncture site;
a power source; and
a microcontroller for instructing the stimulator to selectively generate said pulses.

Abstract
An implantable stimulation device for use in stimulation based treatments for diseases such as GERD or obesity is described. The device is provided with an anchoring unit which upon deployment assumes a shape optimized for the site of deployment. Sensing electrodes and stimulating electrodes in the device are also designed to assume a suitable shape upon deployment. A novel catheter is also provided for easy and expeditious deployment of the device.
