Medical closure device
View Patent ↗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 comprising:
an inner member adapted to be positioned against an inner surface of a blood vessel having a puncture,
an outer member adapted to be positioned against an outer surface of the blood vessel opposite the inner member, and
a retaining member attached to the inner member and the outer member,
wherein the retaining member is in a form of a loop comprising one or more filaments, each filament wound multiple times to form multiple coils of each filament, the coils lying side-by-side one another such that when increasing tension is applied in the loop, at least one of the one or more filaments breaks apart before side-by-side portions of the one or more filaments slide readily with respect to one another, and
wherein the outer member is configured to perform one of locking the inner member to the puncture, sealing the puncture, and a combination thereof.
2. The medical closure device according to claim 1 , wherein the retaining member is provided with a thickened portion made by a multiple winding of at least one filament around a circumference of a portion of the loop, and wherein the at least one filament forming the thickened portion is different from the one or more filaments forming the loop.
3. The medical closure device according to claim 1 , wherein the loop is knotless.
4. The medical closure device according to claim 1 , wherein the inner member is a seal.
5. The medical closure device according to claim 1 , wherein the inner member is an anchor.
6. The medical closure device according to claim 5 , wherein the outer member is in a form of a seal.
7. The medical closure device according to claim 1 , wherein the outer member is a seal.
8. The medical closure device according to claim 7 , wherein the inner member is a seal.
9. The medical closure device according to claim 1 , wherein the outer member is a plug.
10. The medical closure device according to claim 1 , wherein the inner member is an inner disc and the outer member is an outer disc.
11. The medical closure device according to claim 1 , wherein the outer member is a plug of collagen foam.
