Device for Occlusion and Release of Natural or Artificially Constructed Ducts in the Human or Animal Body

Abstract

Abstract 1,174,814. Surgical occluding devices. R. D. GRUNERT. 10 Feb., 1967 [10 Feb., 1966; 23 June, 1966], No. 6579/67. Heading A5R. [Also in Division H2] A device for occluding and releasing a duct in the body comprises an occluding member to be implanted around the duct, and means for operating the occluding member either pneumatically, hydraulically, mechanically, or electrically, the device having an envelope of a material which is compatible with the environment of the body for implantation. As shown, the occluding clamp 1 is operated by an electric motor 19 through gears 21, 22 and a cable end spring arrangement 18, 25, and the clamp and motor together with a battery (26) (Figure 4, not shown) and magnetic switches (27, 28) may be implanted within the body and controlled remotely using magnets. In an alternative embodiment (Figure 1, not shown) the occluding member comprises inflatable jaws (2) operated by a bellows pump (5) which may be located under the skin, or in a modification (Figure 2, not shown), the inflatable jaws are operated by a rotary pump (11). In the embodiment shown, the electric motor 19 may be energized by currents induced in two implanted resonant circuits (Figure 5, not shown) by a coil (37) (Figure 6, not shown) located outside the body. The resonant circuits are arranged to selectively drive the motor in opposite directions.
