Rapidly eroding anchor

Abstract

An anchor for using a closure device includes a body being configured to move from a pre-deployed state to a deployed state. In the pre-deployed state, the body has a first width aspect relative to a direction of deployment and a second width aspect in the deployed state relative to the direction of deployment, the second width aspect being greater than the first width aspect and wherein the body is formed from a rapidly eroding material configured to erode through dissolution within a body lumen.

1 . An anchor for using a closure device, the anchor comprising:
 a body being configured to move from a pre-deployed state to a deployed state, wherein in the pre-deployed state the body has a first width aspect relative to a direction of deployment and a second width aspect in the deployed state relative to the direction of deployment, the second width aspect being greater than the first width aspect and wherein the body is formed from a rapidly eroding material configured to erode through dissolution within a body lumen.   
     
     
         2 . The anchor of  claim 1 , wherein the body is configured to erode in less than twelve hours. 
     
     
         3 . The anchor of  claim 1 , wherein the body is configured to erode in less than one hour. 
     
     
         4 . The anchor of  claim 1 , wherein the body includes a major axis and wherein the body is configured to rotate in response to a force applied parallel to the major axis. 
     
     
         5 . The anchor of  claim 1 , wherein the rapidly eroding material includes at least one of a sugar and a sugar-derivative. 
     
     
         6 . The anchor of  claim 5 , wherein the sugar derivative includes sugar alcohols including mannitol, sorbitol, and isomalt. 
     
     
         7 . The anchor of  claim 5 , wherein the sugar includes at least one of a group including glucose, fructose, lactose and maltose. 
     
     
         8 . The anchor of  claim 1 , wherein the body further includes at least one polymeric component. 
     
     
         9 . The anchor of  claim 8 , wherein the polymeric component includes at least one of poly-vinylpyrrolidone, poly-ethyleneglycol, hydroxyethyl starch, dextran or dextran sulfate. 
     
     
         10 . The anchor of  claim 1 , wherein the rapidly eroding material is water soluble. 
     
     
         11 . The anchor of  claim 1 , wherein the rapidly eroding material forms a crystalline matrix. 
     
     
         12 . The anchor of  claim 1 , wherein the rapidly eroding material forms a glass structure. 
     
     
         13 . The anchor of  claim 1 , wherein the rapidly eroding material includes a plurality of pores. 
     
     
         14 . The anchor of  claim 13 , wherein at least one of the pores includes at least one beneficial agent. 
     
     
         15 . The anchor of  claim 13 , wherein the anchor member includes at least one of poly-vinyl pyrrolidone, hyaluronic acid, dextran, hydrogel, heparin, and benzalkonium heparin. 
     
     
         16 . The closure device of  claim 1 , wherein the anchor member is formed using a freeze-drying process. 
     
     
         17 . A method of closing a puncture in a wall of a body lumen, comprising:
 advancing an anchor in a deployment direction through the anchor, the anchor having a first width aspect relative to the deployment direction;   deploying the anchor distally of the wall of the body lumen to cause the anchor to move to have a second width aspect relative to the deployment direction, the second width aspect being larger than the first width aspect;   drawing the anchor distally into engagement with a distal side of the wall of the body lumen; and   deploying a closure element into the wall of the body lumen, wherein the anchor is formed from a rapidly eroding material that dissolves in the body lumen in less than twelve hours.   
     
     
         18 . The method of  claim 17 , wherein rapidly eroding material dissolves in the body lumen in less than one hour. 
     
     
         19 . The method of  claim 17 , wherein deploying a closure element includes deploying an expandable plug. 
     
     
         20 . The method of  claim 17 , wherein deploying a closure element includes deploying tines into the wall of the body lumen. 
     
     
         21 . A closure device system comprising:
 a delivery sheath;   a rapidly eroding anchor at least partially disposed within the delivery sheath in an initial configuration, the closure member comprising one or more sugars;   a suture element coupled to the closure member and disposed at least partially through the delivery sheath; and   a pusher disposed at least partially within the delivery sheath and configured to deploy the anchor member from a distal end of the delivery sheath.   
     
     
         22 . The closure device system of  claim 21 , further comprising an expandable plug configured to be positioned between the anchor and the pusher. 
     
     
         23 . The closure device system of  claim 21 , further comprising an expandable closure element configured to be moved between an expanded state and a restricted state to close a puncture in a wall of a body lumen.
