Artificial sphincter
First Claim
1. An artificial sphincter for closure of an intestine in a patient'"'"'s body communicating with an opening adjacent the outside of the patient'"'"'s body, comprising:
- an elongated sheet of a relatively thin flexible material containing a particulate first material dispersed throughout a substantial portion of the sheet, said sheet extending at least partially around a channel in the intestine; and
a plug having an insertion portion for placement in the intestine channel and containing a second material, with at least one of said first and second materials comprising, a permanent magnetic material, and the other of said first and second materials comprising a material substantially susceptible to said one magnetic material.

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.

11. 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, comprising:
-
a generally annular member containing a first material for placement at least partially around the channel of the patient'"'"'s body; and a plug having an elongated flexible sidewall of an elastic material for placement within said annular member with said sidewall facing toward walls of said channel, said sidewall containing a particulate second material dispersed through a region in said sidewall, with at least one of said first and second materials comprising a permanent magnetic material, and with the other of said first and second materials comprising a material substantially susceptible to said one magnetic material, said sidewall defining a cavity, and said plug having port means communicating with said cavity to permit inflation of said sidewall. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. An artificial sphincter for closure of a channel in a patient'"'"'s body communicating with an opening outside the patient'"'"'s body, comprising:
-
a generally annular member containing a first material for placement at least partially around the channel of the patient'"'"'s body; and a plug having an outwardly directed rim adjacent a proximal end of the plug, an elongated tubular section extending distally from said rim and defining a lumen, an elongated annular sleeve of elastic material surrounding a longitudinal portion of said tubular section and defining a cavity communicating with said lumen through aperture means in the tubular section, said sleeve containing a particulate second material dispersed through a region of said sleeve, with at least one of said first and second materials comprising a permanent magnetic material, and the other of said first and second materials comprising a material substantially susceptible to said one magnetic material, and said plug having port means communicating with said lumen to permit inflation of said annular member. - View Dependent Claims (20)
