経皮穿刺部を封止するための方法およびシステム

摘要

A device (112) for sealing a puncture in a patient includes a sealing component (11) and a sealing material delivery component (12). The sealing component (11) includes: an elongate control member (20) configured to pass through a puncture in skin of a patient; an expandable member (21) disposed near a distal end of the elongate control member (20); and a tip (23) releasably attached to the elongate control member (20) distal to the expandable member (21). The sealing material delivery component (12) includes: a delivery tube (60) through which the elongate control member (20) of the sealing component (11) is configured to extend. The delivery tube (60) includes a first cavity configured to deliver a first sealing material (67) to a location near the puncture in the patient when the expandable member (21) in an expanded configuration abuts a surface defining a distal opening of the puncture. A second sealing material (68) is delivered to a location near the first sealing material (67) in the patient, through either the delivery tube (60) or a guide sheath (GS) when the delivery tube (60) and the elongate control member (20) are withdrawn from the guide sheath (GS),
