    摘要： Apparatus for sealing a vascular wall penetration disposed at the end of the tissue tract comprises a shaft, an occlusion element, a hemostatic implant, and a protective sleeve. The apparatus is deployed through the tissue tract with the occlusion element temporarily occluding the vascular wall penetration and inhibiting backbleeding therethrough. The hemostatic implant, which will typically be a biodegradable polymer such as collagen carrying an anti-proliferative agent or coagulation promoter, will then be deployed from the sealing apparatus and left in place to enhance closure of the vascular wall penetration with minimum scarring. The implant may be radiopaque to allow observation before release.

    摘要： The present invention advantageously provides self-tensioning occlusion devices, systems, and methods for percutaneous access and closure of vascular puncture sites. One device comprises a catheter body, an occlusion member, and a tensioning member. The occlusion member, such an expansible member, is disposed on a distal end of the body. The tensioning member, such as a spring or coil, is slidably disposed over the body and proximal the expansion member. Generally, during application, the tensioning member will be deployed against subcutaneous tissue so as to apply tension to the expansible member against the puncture site. The substantial hold once the tension is applied is then provided by external means, such as an anchoring clip.

    摘要： 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 chemical and/or biological 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 chemical and/or biological sealing member disposed proximal the expansible member is then displaced so as to expose a chemical and/or biological region or release region of the device. At least one chemical and/or biological agent is thereafter released from the device and into the tissue tract to accelerate the occlusion process in the tract.

    摘要： The present invention provides devices, systems, and methods for percutaneously sealing a puncture site in tissue tracts and vessels in human or animal bodies. One system includes a locating assembly that is used to locate the puncture site and can also provide temporary hemostasis when the system is used for closing a vessel puncture. The system also includes a compression assembly comprising a tubular member with a balloon on a distal end thereof. This balloon is at a fixed distance from the locator tip which locates the balloon outside the vessel wall at a predetermined distance. Inflation of this balloon causes forward elongation of the balloon which compresses subcutaneous tissue between the distal tip of the balloon and the vessel wall. This tissue compression against the puncture site is the mechanism that provides hemostasis.
