Abstract:
Drug eluting vascular closure devices and methods for closing a blood vessel puncture site disposed at a distal end of a tissue tract are described. The devices and methods rely on a combination of the body's own natural mechanism to achieve hemostasis with bio-chemical agents to accelerate the hemostatic process. One method includes the steps of introducing a closure device through the tissue tract and deploying an expansible member at a distal end of the device within the blood vessel to occlude the puncture site. A bio-chemical sealing member disposed proximal the expansible member is then displaced so as to expose a bio-chemical region or release region of the device. At least one bio-chemical agent is thereafter released from the device and into the tissue tract to accelerate the occlusion process in the tract.
