Vessel occlusive device and method of occluding a vessel

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;
• reactuating the vessel occlusive device into the biased occluding position when fluid flow is no longer to be allowed;
• and
• passively eluting at least one solution from the vessel occlusive device into the body, the solution comprising a solution to provide a therapeutic effect when eluted.

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;
• 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;
• and
• a boot that covers the control mechanism, the boot includes a septum configured for introducing at least one fluid into the control mechanism and the occlusive member, the occlusive member being configured to passively elute the fluid introduced.
