Patent ID: 8753363

Claim:
An implantable apparatus for occluding a fluid conveying body vessel comprising: an outer sheath having an internal space that is configured to retain a liquid, the outer sheath being water tight and having a first end and a second end, at least a portion of the outer sheath configured to at least partially encircle the fluid conveying body vessel; an inner occlusive tape disposed through the inner space, the inner occlusive tape having a first end and a second end, wherein the first end of the inner occlusive tape is fixed to the first end of the outer sheath, the second end of the inner occlusive tape is movable relative to the outer sheath, and the inner occlusive tape having a rectangular cross-section with a varied width from the first end to the second end of the inner occlusive tape; and a control mechanism connected to the second end of the inner occlusive tape, the control mechanism having an activated state and a deactivated state, wherein in the activated state the control mechanism applies a tension to the inner occlusive tape so that the inner occlusive tape applies a pressure to the portion of the outer sheath encircling the fluid conveying body vessel, and when the inner occlusive tape is adjusted to encircle the fluid conveying body vessel, the varied width of the inner occlusive tape is configured to increase or decrease the pressure on the fluid conveying body vessel, and in the deactivated state the control mechanism releases the tension from the inner occlusive tape so that the inner occlusive tape releases the pressure from the portion of the outer sheath encircling the fluid conveying body vessel.
