Vasculature closure devices

Abstract

Vasculature closure devices, and systems and methods for their use, are provided. In one embodiment, the vasculature closure device includes an expandable support frame deployable into a vessel through a puncture site and a sealing membrane at least partially supported by the expandable support frame. The support frame is positioned along a periphery of the sealing membrane. Upon expanding the support frame within the vessel, the support frame is configured to intraluminally push the sealing membrane against the puncture site.

We claim: 
     
         1 . A vasculature closure device for sealing a puncture site existing in a wall of a vessel, the device comprising:
 an expandable support frame deployable into the vessel through the puncture site;   a sealing membrane at least partially supported by the support frame;   wherein the support frame is positioned along a periphery of the sealing membrane; and   wherein, upon expanding the support frame within the vessel, the support frame is configured to intraluminally push the sealing membrane against the puncture site.   
     
     
         2 . The device of  claim 1 , wherein, upon expanding the support frame within the vessel, the support frame is configured to extend along a majority of an inner circumference of the vessel such that the sealing membrane is pushed against the puncture site. 
     
     
         3 . The device of  claim 1 , wherein, upon expanding the support frame within the vessel, the support frame is configured to hold the device in place within the vessel. 
     
     
         4 . The device of  claim 1 , wherein, upon deploying the support frame within the vessel, the support frame and the sealing membrane are positioned entirely within the vessel. 
     
     
         5 . The device of  claim 1 , wherein the device is adapted for rolling and unrolling along a longitudinal axis generally aligned with and extending along a length of the vessel. 
     
     
         6 . The device of  claim 5 , wherein the device is adapted for rolling into a collapsed configuration having a first radius of curvature less than a radius of curvature of the vessel, and wherein the device is adapted for unrolling into an expanded configuration having a second radius of curvature greater than the radius of curvature of the vessel. 
     
     
         7 . The device of  claim 5 , wherein the device is adapted for rolling into a collapsed configuration in which opposing sides of the support frame overlap one another. 
     
     
         8 . The device of  claim 7 , wherein the device is adapted for unrolling into an expanded configuration in which the opposing sides of the support frame are spaced apart from one another. 
     
     
         9 . The device of  claim 1 , wherein the support frame is formed of a non-biodegradable material, and wherein the sealing membrane is formed of a biodegradable material. 
     
     
         10 . The device of  claim 1 , wherein the support frame is formed of a pre-shaped material adapted for expanding toward a stable state. 
     
     
         11 . The device of  claim 1 , further comprising an anchoring tab or a pull string extending away from the sealing membrane. 
     
     
         12 . The device of  claim 11 , wherein, upon expanding the support frame within the vessel, the anchoring tab or the pull string is configured to extend out of the vessel through the puncture site. 
     
     
         13 . The device of  claim 1 , further comprising a support member extending across at least a portion of the sealing membrane and attached to opposing sides of the support frame. 
     
     
         14 . The device of  claim 13 , wherein the support member comprises a wire extending along a longitudinal axis of the device. 
     
     
         15 . The device of  claim 1 , wherein at least a portion of the sealing membrane is configured to move relative to the support frame such that the sealing membrane conforms to a shape of the wall of the vessel near the puncture site. 
     
     
         16 . The device of  claim 1 , wherein the sealing membrane is coupled to the support frame via a plurality of tabs encircling respective portions of the support frame. 
     
     
         17 . The device of  claim 16 , wherein the tabs are configured to slide along the respective portions of the support frame such that at least a portion of the sealing membrane moves relative to the support frame. 
     
     
         18 . The device of  claim 1 , wherein the sealing membrane comprises excess material relative to the support frame such that the sealing membrane conforms to a shape of the wall of the vessel near the puncture site. 
     
     
         19 . A vasculature closure device for sealing a puncture site existing in a wall of a vessel, the device comprising:
 an expandable support frame deployable into the vessel through the puncture site;   a sealing membrane at least partially supported by the support frame;   wherein the support frame is formed of a non-biodegradable material;   wherein the sealing membrane is formed of a biodegradable material; and   wherein, upon expanding the support frame within the vessel, the support frame is configured to intraluminally push the sealing membrane against the puncture site.   
     
     
         20 . A vasculature closure device for sealing a puncture site existing in a wall of a vessel, the device comprising:
 an expandable support frame deployable into the vessel through the puncture site;   a sealing membrane at least partially supported by the support frame;   wherein the device is adapted for rolling and unrolling along a longitudinal axis generally aligned with and extending along a length of the vessel;   wherein the device is adapted for rolling into a collapsed configuration in which opposing sides of the support frame overlap one another; and   wherein, upon expanding the support frame within the vessel, the support frame is configured to intraluminally push the sealing membrane against the puncture site.
