System and method for vessel access closure
First Claim

1. A method for closing a hole in a vessel having a vascular lumen formed by the vessel, comprising:
- a. inserting through the hole and into the lumen (i) an introducer sheath and (ii) then inserting an implantable closure device having proximal and distal ends and being expandable within the lumen from a collapsed state to an expanded state, the expanded state providing a geometry sufficient to at least substantially occlude the hole, the introducer sheath defining a an introducer lumen sized to accommodate insertion of the closure device in its collapsed state;
b. inserting a distal portion of an elongate guiding member through the hole and into the vascular lumen; and
c. expanding the implantable closure device to the expanded state within the lumen to at least substantially occlude the hole, while leaving the distal portion of the elongate guiding member extending into the vascular lumen whereby the guiding member can be used to access the lumen in subsequent operations performed on the vessel.

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.

23. A method for closing a hole in a vessel having a vascular lumen formed by the vessel, comprising:
-
a. inserting through the hole and into the lumen an implantable closure device having proximal and distal ends and being expandable within the lumen from a collapsed state to an expanded state, the expanded state providing a geometry sufficient to at least substantially occlude the hole; b. inserting a distal portion of an elongate guiding member through the hole and into the vascular lumen, wherein inserting the implantable closure device through the hole and into the lumen comprises advancing the implantable closure device relative to the hole with a deployment member having a proximal portion configured for manual manipulation and a distal portion configured to be removably coupled to the implantable closure device; and c. expanding the implantable closure device to the expanded state within the lumen to at least substantially occlude the hole, while leaving the distal portion of the elongate guiding member extending into the vascular lumen whereby the guiding member can be used to access the lumen in subsequent operations performed on the vessel. - View Dependent Claims (24, 25, 26, 27, 28)
