Patent ID: 7993366

Claim:
A system for hemostasis of a puncture site in a body lumen, the system comprising: a catheter comprising: (i) a catheter body having a proximal end, a distal end, and at least one axial lumen therethrough; (ii) an occlusion member capable of being radially expanded and contracted at the distal end of the catheter body; (iii) a helical coil spring having a central passage which receives the catheter body and having a distal end fixedly attached to the distal end of the catheter body and a proximal end having a user grip which allows the user to pull proximally on the coil spring to tension the occlusion member against the puncture site; and (iv) an axial member slideably disposed in the axial lumen of the catheter body to selectively radially expand and contract the occlusion member; and an external clip coupleable to the proximal end of the coil spring to engage a skin surface in order to hold said proximal end in place over the tissue tract.
