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.

Claims

1. An apparatus for closing a hole in a vessel comprising:

a sheath;

a deployment member having proximal and distal ends;

an implantable closure device having proximal and distal ends, the implantable device being removably coupled to the distal end of the deployment member and being expandable from a collapsed state to an expanded state after the implantable device is inserted through the hole into a lumen defined by the vessel, the expanded state providing a geometry to substantially occlude the hole;

a catch member configured to extend away from the proximal end of the implantable device by a catch member length, wherein the catch member length is selected to extend within the lumen and disposed relative to the implantable device to prevent withdrawal of the implantable closure device back through the hole prior to expansion to said expanded state and wherein the deployment member and catch member are slidable within the sheath;

a foot member having proximal and distal ends and a flexible portion therebetween, the flexible portion accommodating rotation of the distal end relative to the proximal end, wherein the distal end of the foot member is releasably coupled to the closure device and the proximal end of the foot member is coupled to the deployment member;

a rotation actuating member coupled to the distal end of the foot member to controllably rotate to the proximal end of the foot member; and

wherein the rotation actuating member comprises an elongate bending spring member coupled to the proximal and distal portions of the foot member.

2. The apparatus of claim 1, wherein the catch member is reconfigurable from a deployed configuration, wherein the catch member is in a position that extends to prevent withdrawal of the implantable closure device, to a retracted configuration, wherein the catch member is retracted back toward the deployment member to facilitate removal of the deployment member back through the hole.

3. The apparatus of claim 2, wherein the catch member comprises a cantilevered portion coupled to a manually advanceable portion, the advanceable portion being approximately aligned with a longitudinal axis of the deployment member and configured to pull the cantilevered portion into alignment with the advanceable portion with increased advancement of the advanceable portion.

4. The apparatus of claim 2, wherein the catch member comprises a cantilevered portion coupled to a manually advanceable portion and wherein the advanceable portion comprises proximal and distal ends, and wherein the catch member is coupled to the advanceable portion at a coupling point in between the proximal and distal ends and is directed away from the deployment member at the coupling point through an aperture in the deployment member.

5. The apparatus of claim 2, wherein the catch member is an independently slidable elongate wire having a distal portion curved to bend away from the deployment member in the deployed configuration.
