Vessel occlusive apparatus and method
First Claim
1. An occlusive apparatus for reversibly occluding a fluid conveying vessel in a body, comprising:
- an occlusive member adapted for at least partially encircling the vessel, said occlusive member including an intrinsic spring force therein for exerting an occluding pressure on the vessel while the occlusive member at least partially encircles the vessel; and
a control mechanism operatively connected to said occlusive member, said control mechanism being arranged and configured to counteract the intrinsic spring force of said occlusive member and thereby remove the occluding pressure on the vessel while the occlusive member is at least partially encircling the vessel.

Abstract
An occlusive apparatus and method for reversibly occluding fluid conveying vessels in the body. In one embodiment, the occlusive apparatus includes an occlusive member adapted for at least partially encircling a vessel, with the occlusive member including an intrinsic spring force therein for exerting an occluding pressure on the vessel while the occlusive member at least partially encircles the vessel. A control mechanism is operatively connected to the occlusive member, with the control mechanism being arranged and configured to counteract the intrinsic spring force of the occlusive member and thereby remove the occluding pressure on the vessel while the occlusive member is at least partially encircling the vessel.

18. An apparatus for reversibly occluding a fluid conveying vessel in a body, comprising:
-
an occlusive member adapted for at least partially encircling the vessel, said occlusive member including an intrinsic resilient biasing force which biases the occlusive member to a contracted state for exerting an occluding pressure on the vessel while the occlusive member at least partially encircles the vessel; and a control mechanism operatively connected to said occlusive member for actuating the occlusive member to an expanded state, said control mechanism being arranged and configured to counteract the intrinsic resilient biasing force of said occlusive member and thereby force the occlusive member to the expanded state and remove the occluding pressure on the vessel while the occlusive member is at least partially encircling the vessel. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)

26. An apparatus comprising:
-
an expandable and contractable member adapted for at least partially encircling a body vessel, said member including an intrinsic resilient biasing force which biases the member to a contracted state; an abdominal pressure sensor adapted for sensing abdominal pressure; and a control mechanism operatively connected to said member and interfacing with the abdominal pressure sensor, said control mechanism being arranged and configured to control expansion and contraction of the member in response to the abdominal pressure sensed by the abdominal pressure sensor.

27. A method for controlling fluid flow in a fluid conveying body vessel, comprising the steps of:
-
surrounding at least a portion of the vessel with a member that is resiliently biased to a contracted state such that an occluding pressure is exerted on the vessel when the member is in the contracted state; and selectively forcing the member to an expanded state thereby at least partially removing the occluding pressure on the vessel. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34)
