US Patent 8114125 Apparatus for sealing surgical punctures

Apparatus is provided for sealing a puncture within a vessel or tissue to provide hemostasis, comprising a first disk coupled to either a second disk or a spring, and sealingly engaged to the vessel or tissue surrounding the puncture. At least the first disk is preferably configured to substantially conform to the profile of the vessel or tissue when deployed. In one embodiment, the disks may be released from engagement with the vessel or tissue to reposition the disks after deployment.
