VASCULAR CLOSURE DEVICE

摘要

A device for closure of an opening formed through a wall of a body vessel of a patient is provided, as well as an introducer system for delivery of the closure device. Various embodiments include the closure device having hook members configured to engage the tissue interior of the body vessel wall, hook members configured to engage interstitial tissue adjacent to the body vessel, a plug member to contact sealably the opening from inside the body vessel, and combinations thereof. A retraction member is removably attached to the each of the embodiments to permit manipulation of the device. Remodelable material may be included with each of the embodiments to promote quicker healing. The introducer includes a sheath that is insertable through the opening and a pusher disposed within the lumen of the sheath and movable within the sheath lumen to deploy the device.

主权项

1. A device for closure of an opening formed through a wall of a body vessel of a patient, comprising:
an anchor body having a proximal end and a distal end, the proximal end including a plurality of hook members configured to engage interstitial tissue adjacent to said body vessel to inhibit movement of the anchor body, wherein the anchor body is movable between a contracted configuration and an extended configuration, where in the contracted configuration the anchor body is sized to fit within a channel through said interstitial tissue, and in the extended configuration the hook members of the anchor body are displaced outward to a cross-sectional area greater than the cross-sectional area of said opening; a plug member attached to the anchor body distal end, the plug member sized to at least substantially fill said opening; and a retraction member removably attached to a portion of the anchor body, wherein the retraction member is retractable to bring the plug member in sealably contact with said opening.
