Patent ID: 7753933

Claim:
An apparatus for sealing a passage through tissue in a body, comprising: an elongate delivery device comprising a lumen extending between proximal and distal ends thereof, and defining a longitudinal axis; a plug member detachably carried by the distal end of the delivery device and comprising a lumen communicating with the lumen of the delivery device, wherein the plug member is configured to be inserted through the tissue; and a guide wire element comprising a proximal end receivable through the lumens in the plug member and the delivery device, the guide wire element comprising a first and second portion slidable relative to each other and a plurality of lateral elements on a distal portion thereof, the plurality of lateral elements being deflectable from an expanded configuration towards a collapsed configuration within the body substantially parallel to the delivery device such that relative motion between the first and second portion of the guide wire element causes the lateral elements to deflect.
