ABSTRACT:
An implantate comprising an essentially annular permanent magnet which is axially magnetized is located in the vicinity of an orifice from an intestine, surrounding the intestine. A plug element having a core of magnetic material and an outer casing is inserted into the intestinal orifice. The casing is essentially cylindrical and is made of a material which is radially compressible, and inserted in the orifice, the magnetic material within the core thereof -- which is preferably removable -- in cooperation with the magnetic field from the permanent magnet locating the plug element within the orifice to establish an axial equilibrium position and hold the plug element in position closing the orifice.
