Medical closure device

Abstract

A medical closure device ( 1; 20 ) comprising an inner member ( 2; 23 ), which is adapted to be positioned against an inner surface of a tissue wall, and a retaining member ( 3; 13; 21 ), which is attached to the inner member, wherein the retaining member is in the form of a loop made up by multiple coils of at least one filament, the coils lying side-by-side one another such that when increasing tension is applied in the loop, at least one of the at least one filament breaks apart before side-by-side portions of the at least one filament slide readily with respect to one another.

1 . A medical closure device ( 1 ;  20 ) comprising an inner member ( 2 ;  23 ), which is adapted to be positioned against an inner surface of a tissue wall, and a retaining member ( 3 ;  13 ;  21 ), which is attached to the inner member, wherein the retaining member is in the form of a loop made up by multiple coils of at least one filament, the coils lying side-by-side one another such that when increasing tension is applied in the loop, at least one of the at least one filament breaks apart before side-by-side portions of the at least one filament slide readily with respect to one another. 
   
   
       2 . A medical closure device according to  claim 1 , wherein the closure device further comprises an outer member ( 24 ), which is adapted to be positioned against an outer surface of the tissue wall, wherein the retaining member is provided with a thickened portion ( 22 ) made by multiple winding of at least one filament around the circumference of a portion of the loop. 
   
   
       3 . A medical closure device according to  claim 1 , wherein the loop is knotless. 
   
   
       4 . A medical closure device according to  claim 1 , wherein the medical closure device is adapted for closing a puncture in a vessel wall. 
   
   
       5 . A medical closure device according to  claim 1 , wherein the medical closure device is adapted for closing a septal defect in a heart.
