Abstract

Apparatus for sealing a puncture includes an elongate occlusion member having a balloon attached to distal ends of telescoping inner and outer members. A housing on the proximal end of the outer member includes a piston coupled to the inner member and slidable within a chamber communicating with a fluid reservoir. A switch on the housing is actuated to direct fluid from the reservoir through the outer member into the balloon to expand the balloon and into the chamber to move the piston and pull the inner member, shortening the balloon as it expands. During use, the distal end of the occlusion member is introduced into a puncture communicating with a vessel until the collapsed balloon is disposed within the vessel. The balloon is expanded, and a tensioner is connected to the housing to apply a proximal force holding the balloon against the vessel wall to seal the puncture.

Claims6

Dependent claims

A method for sealing a puncture extending from a patient's skin to a body lumen, comprising:

introducing a distal end of an occlusion member into the puncture with an expandable member thereon in a collapsed state until the expandable member is disposed within the body lumen;
expanding the expandable member to an expanded state within the body lumen;
placing a foot of a tensioner against the patient's skin adjacent the puncture, the tensioner comprising a shaft extending from the foot, and a saddle movable along the shaft towards the foot and biased to move away from the foot;
directing the saddle along the shaft towards the foot to reduce a distance between the saddle and the foot;
connecting the saddle to a proximal end of the occlusion member;
and
releasing the saddle, whereupon the saddle automatically moves away from the foot, thereby applying a proximal force on the occlusion member to hold the expandable member against a wall of the body lumen and substantially seal the puncture from the body lumen.
