SYSTEM AND METHOD FOR VESSEL ACCESS CLOSURE
First Claim
Patent Images
1. A method for closing a hole in a vessel, comprising:
- a. inserting through the hole an implantable closure device having proximal and distal ends and being expandable from a collapsed state to an expanded state, the expanded state providing a geometry sufficient to substantially occlude the hole;
b. inserting a distal portion of an elongate guiding member through the hole and into a vascular lumen formed by the vessel; and
c. controllably expanding the implantable closure device to the expanded state to occlude the hole, while leaving the distal portion of the elongate guiding member extending into the vascular lumen.

Abstract
Embodiments are described for closing vascular access ports, such as arteriotomies, which involve placement and deployment of an expandable device configured to prevent blood flow across a subject arteriotomy while also keeping disturbance of intravascular flow to a minimum. Suitable prostheses may comprise one or more frames constructed from lengths of flexible materials, such as shape memory alloys or polymers. Such frames may be coupled to sheetlike or tube-like structures configured to spread loads, minimize thrombosis which may be related to intravascular flow, and maintain hemostasis.
