APPARATUS AND METHODS FOR SEALING A PUNCTURE IN TISSUE

摘要

An occlusion device for sealing a puncture through tissue includes a tubular wire member having a proximal end, a distal end sized for insertion into the puncture, a lumen extending between the proximal and distal ends, a port adjacent the proximal end communicating with the 5 lumen, and a balloon on the distal end. A source of fluid is connectable to the wire member for delivering fluid via the port into the lumen for expanding the balloon. A fluid loading device is disposed on the proximal end of the wire member to receive the source of fluid and to deliver fluid within the lumen into the balloon to expand the balloon.

1. An occlusion device for sealing a puncture through tissue, comprising:
an elongate tubular member comprising a proximal end, a distal end sized for insertion into a puncture, a lumen extending at least partially between the proximal and distal ends, and an expandable occlusion element carried on a distal region of the tubular member, the occlusion element having an interior communicating with a distal opening in the lumen, the tubular member having a substantially uniform diameter extending between the proximal end and the distal region; and a fluid loading device receivable on the proximal end of the elongate tubular member for delivering fluid into, and drawing fluid out of, the interior of the occlusion element to thereby expand and collapse the occlusion element.
