Vascular Hole Closure Device

Abstract

A device for closing an aperture in a vessel wall comprising a covering member having a longitudinal axis and positionable inside the vessel against the internal opening of the aperture and having a dimension to prevent egress of fluid through the aperture and having a first opening. A first retainer is positionable external of the vessel. A flexible connecting member operatively connects the covering member and the first retainer, wherein the first opening of the covering member is configured to restrict movement of the connecting member.

1 . A device for closing an aperture in a vessel wall, the aperture having an external opening in an external region of the vessel wall and an internal opening in an internal region of the vessel wall, the device comprising:
 a covering member positionable inside the vessel against the internal opening of the aperture, the covering member having a dimension to prevent egress of fluid through the aperture, the covering member having a first opening;   a first retainer positionable external of the vessel; and   a flexible connecting member operatively connecting the covering member and the first retainer, the connecting member advancing the first retainer toward the covering member, the first opening of the covering member configured to restrict movement of the connecting member.   
     
     
         2 . The device of  claim 1 , wherein the connecting member comprises a first suture, and the first retainer is attached to the suture. 
     
     
         3 . The device of  claim 2 , wherein pulling of the first suture moves the first retainer toward the covering member. 
     
     
         4 . The device of  claim 3 , wherein the first retainer is spherical in configuration. 
     
     
         5 . The device of  claim 1 , further comprising a second retainer movable toward the covering member. 
     
     
         6 . The device of  claim 5 , further comprising a second flexible connecting member, the second retainer attached to the second suture and pulling of the second connecting member advances the second retainer toward the covering member, the covering member having a second opening configured to restrict movement of the connecting member. 
     
     
         7 . The device of  claim 6 , wherein the second retainer is spherical in configuration. 
     
     
         8 . The device of  claim 1 , wherein the covering member is composed of a polymeric material. 
     
     
         9 . The device of  claim 1 , wherein the covering member and first retainer are composed of a resorbable material. 
     
     
         10 . The device of  claim 2 , further comprising a second suture and second retainer attached to the second suture, the second suture advancing the second retainer toward the covering member. 
     
     
         11 . The device of  claim 10 , wherein the first and second retainers are positioned in a substantially side by side relationship in a placement position and are positioned in a stacked relationship in a delivery position. 
     
     
         12 . The device of  claim 10 , wherein the first and second retainers are in a transverse orientation with respect to the covering member in the placement position. 
     
     
         13 . The device of  claim 10 , wherein the first and second retainers and the first and second sutures are composed of a resorbable material. 
     
     
         14 . The device of  claim 1 , wherein the first opening of the covering member has a dimension to frictionally engage the connecting member. 
     
     
         15 . The device of  claim 1 , wherein the covering member is pivotable between a more longitudinal orientation for delivery and a transverse position for placement. 
     
     
         16 . The device of  claim 10 , further comprising a third opening in the covering member for unrestricted movement of the first suture and a fourth opening in the covering member for unrestricted movement of the second suture. 
     
     
         17 . A method of closing an aperture in a vessel wall, the aperture having an external opening in an external region of the vessel wall and an internal opening in an internal region of the vessel wall, the method comprising:
 inserting a covering member inside the vessel against the internal opening of the aperture, the covering member having a dimension to prevent egress of fluid through the aperture and having a connecting member extending therefrom; and   inserting a first retainer external of the vessel; and   applying a sufficient force to overcome resistance to movement of the connecting member to advance the first retainer toward the covering member.   
     
     
         18 . The method of  claim 18 , wherein the step of advancing the first retainer comprises the step of moving a first suture attached to the first retainer through an opening having a diameter substantially the same as the outer diameter of the suture. 
     
     
         19 . The method of  claim 18 , further comprising the steps of inserting a second retainer external of the vessel and advancing the second retainer toward the covering member by pulling a second suture connected to the second retainer. 
     
     
         20 . The method of  claim 17 , wherein the step of advancing the first retainer comprises the step of moving a first suture attached to the first retainer between bumps on the covering member.
