ABSTRACT:
An artificial sphincter for closure of a channel in a patient's body communicating with an opening adjacent the outside of the patient's body. The sphincter comprises, an elongated sheet of relatively thin flexible material containing a particulate first material dispersed throughout a substantial portion of the sheet, with the sheet extending at least partially around the channel. The sphincter also has a plug having an elongated annular sleeve of elastic material defining a cavity communicating with a port in the plug, such that the sleeve may be inflated in the body channel. The sleeve has a second particulate material dispersed throughout a region in the sleeve, with at least one of the first and second materials comprising a permanent magnetic material, and with the other of the first and second materials comprising a material substantially susceptible to the one magnetic material.
