VESSEL OCCLUSIVE DEVICE AND METHOD OF OCCLUDING A VESSEL
First Claim
1. An apparatus for occluding a fluid conveying vessel in a body, comprising:
- an occlusive member having proximate and distal ends, the occlusive member including a conduit region proximately disposed toward the proximate end and a pliable region proximately disposed toward the distal end, the occlusive member being actuatable to an occluding position and actuatable to a non-occluding position where an occlusive force is respectively transmitted to and released from the occlusive member, and where the pliable region is configured to at least partially encircle the vessel and is configured to exert an occluding pressure on the vessel, when the occlusive force is transmitted through the conduit region; and
a control mechanism connected to the conduit region of the occlusive member, the control mechanism is configured to actuate the occlusive member into the occluding position and actuate the occlusive member into the non-occluding position.

Abstract
An implantable vessel occlusive device and method for occluding a vessel are described, for example to occlude the urethra or bladder neck. The devices and methods described utilize an occlusive member connected to a control mechanism. The occlusive member is reversibly changed from a non-occlusive condition to an occlusive condition, for example by depressing an activation button contained within a resilient, elastomeric cover surrounding the control mechanism. In the occlusive position, an initial tension is applied to the occlusive member through a tensioning suture. The tension is translated into an occlusive pressure applied to the urethra or bladder neck that is sufficient to prevent urinary leakage. The non-occlusive position can be obtained by depressing the de-activation button. The occlusive member is constructed to allow elution of drugs, such as may be required to combat infection or tissue encapsulation from its surface.

17. A method for controlling fluid flow in a fluid conveying body vessel, comprising:
-
implanting a vessel occlusive device inside the body of a subject in need of controlled fluid flow through a fluid conveying vessel, the step of implanting comprises surrounding at least a portion of the fluid conveying vessel, actuating the vessel occlusive device into a biased occluding position and applying an occlusive force to occlude the fluid conveying vessel; releasing the occlusive force applied to the fluid conveying vessel when fluid flow is to be allowed through the fluid conveying vessel, the step of releasing occlusive force comprises actuating the vessel occlusive device away from the biased occluding position to a non-occluding position; and reactuating the vessel occlusive device into the biased occluding position when fluid flow is no longer to be allowed. - View Dependent Claims (18, 19, 20)
