Abstract
The present invention advantageously provides self-tensioning occlusion devices, systems, and methods for percutaneous access and closure of vascular puncture sites. One device includes 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 an external element, such as an anchoring clip.
