Abstract

A system for connecting a medical implant to an insertion aid, comprising: a medical implant made of a helically wound wire, wherein the wire is formed into a first loop at the proximal end of the medical implant; a cylindrical, hollow insertion aid with a second loop at the distal end of the insertion aid; and a locking wire, which extends through the hollow insertion aid and is relatively movable to the insertion aid; wherein in a first operating state, in which the medical implant is connected to the insertion aid, the second loop of the insertion aid extends through the first loop of the medical implant and the locking wire extends through the second loop of the insertion aid, so that the first loop of the medical implant is arranged between the second loop of the insertion aid and the locking wire; and wherein in a second operating state the locking wire is retracted into the hollow insertion aid and out of the second loop, so that the first loop of the medical implant is no longer connected to the second loop of the insertion aid. A medical implant for such a system.

Claims (14)

1. A system for connecting a medical implant to an insertion aid, comprising:

a medical implant made of a helically wound wire, wherein the wire is formed into a first loop at the proximal end of the medical implant;

a cylindrical, hollow insertion aid with a second loop at the distal end of the insertion aid; and

a locking wire, which extends through the hollow insertion aid and is relatively movable to the insertion aid;

wherein, in a first operating state, in which the medical implant is connected to the insertion aid, the second loop of the insertion aid extends through the first loop of the medical implant and the locking wire extends through the second loop of the insertion aid, so that the first loop of the medical implant is arranged between the second loop of the insertion aid and the locking wire;

wherein, in a second operating state the locking wire is retracted into the hollow insertion aid and out of the second loop, so that the first loop of the medical implant is no longer connected to the second loop of the insertion aid; and

wherein the medical implant has a double helical winding at the proximal end, one winding into the direction of the first loop and one winding back into the direction of the distal end, which are interleaved to build a continuous surface.

2. The system according to claim 1 , wherein in the first operating state the locking wire extends through the second loop of the insertion aid and further into the proximal end of the medical implant.

3. The system according to claim 1 , wherein at least one end of the medical implant wire is smooth, wherein the end of the medical implant wire is smoothed by at least one of providing a smooth welding spot at the end of the medical implant wire or by providing a blunted tip to the end of the medical implant wire.

4. The system according to claim 3 , wherein the end of the medical implant wire is smoothed by providing the smooth welding spot at the end of the medical implant wire.

5. The system according to claim 3 , wherein the end of the medical implant wire is smoothed by providing the blunted tip to the end of the medical implant wire.

6. The system according to claim 1 , wherein the wire of the medical implant is at least one of mechanically or chemically treated to amend one or more features of the medical implant.

7. The system according to claim 6 , wherein the wire of the medical implant is at least one of mechanically or chemically treated to amend biocompatibility of the medical implant.

8. The system according to claim 6 , wherein the wire of the medical implant is at least one of mechanically or chemically treated to amend mechanical characteristics of the medical implant.
