  • Patent number: 4231369
    Abstract: The invention relates to a sealing material for use in connection with ostomy devices, particularly stoma pouches, to surround and protect a stoma in the human body. The improvement is that the material is a shaped, gel-like composition composed of a largely continuous phase consisting of a physically cross-linked elastomer or a mixture of such elastomers, and preferably, but optionally, one or more hydrocarbon tackifier resins and likewise optionally, but preferably, an oil extender; and distributed in the continuous phase one or more hydrocolloids. The gel-like composition has a low resistance to quick deformation and a rapid recovery to the original shape after deformation.

  • Patent number: 4154226
    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.
