Abstract:
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 uniform outside diameter extending between the proximal end and the distal region and including the proximal end; and an elongate piston member movable within the lumen of the 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, the piston member having a proximal end extending from a proximal opening of the tubular member lumen.
