Vascular Closure Device With Conforming Plug Member

摘要

A vascular closure device includes a delivery assembly, an anchor member carried by the delivery assembly, and a suture attached to the anchoring member. A plug member can be disposed in the delivery assembly and attached to suture such that the plug member. The plug member includes a plug body, a pair of ridges that project from the plug body, and a select location disposed between the pair of ridges. The plug member configured to, in response to a force applied to the select location, transition from an insertion configuration, whereby the plug member is elongate along an insertion direction, into a collapsed configuration, whereby the plug member is collapsed along the insertion direction.

1. A vascular closure device, comprising:
a delivery assembly configured to be inserted into a puncture of a vessel; an anchor member carried by the delivery assembly; a suture attached to the anchoring member and extending into the delivery assembly; and a plug member disposed in the delivery assembly, the plug member attached to the suture so that the plug member is proximal to the anchor member, the plug member including a plug body, a pair of ridges that project from the plug body, and a select location that is disposed between the pair of ridges, the plug member configured to, in response to a force applied to the select location, transition from an insertion configuration, whereby the plug member is elongate along an insertion direction, into a collapsed configuration, whereby the plug member is collapsed along the insertion direction, wherein when the plug member is deployed against the puncture in the collapsed configuration, a portion of the plug body and a portion of the pair of ridges cover the puncture and conforms to a shape of the vessel adjacent the puncture.
