Abstract

A surgical fastener deployment system may include a plurality of coil fasteners having a head and coil body. In some embodiments, the head is comprised of a bioabsorbable polymer. In one embodiment, the coil body may be comprised of a shell and a core and one of the shell and the core may be comprised of one of a magnesium alloy or a bioabsorbable polymer, and the other of the shell and core is formed of the other of the magnesium alloy and the bioabsorbable polymer. The coil body may also include an internal channel which may have a support coil disposed within.

First claim

What is claimed is:

1. A method of applying a surgical fastener, the method comprising:
inserting a support into a channel of the surgical fastener, wherein the channel is formed in and extending along at least a portion of a length of a coil winding of the surgical fastener, wherein the coil winding is attached to and extends distally from a head of the surgical fastener, and wherein the coil winding is formed separately from the head; and
deploying the surgical fastener while the support is at least partially located in the channel to support the surgical fastener and resist deformation of the surgical fastener during deployment.

2. The method of claim 1 , further comprising inserting the support into the channel through a hole formed in a proximal surface of the head of the coil fastener.

3. The method of claim 2 , wherein the hole is radially offset from a central portion of the head.

4. The method of claim 1 , further comprising rotating the surgical fastener as it is deployed.

5. The method of claim 1 , wherein the channel extends along an entire length of the coil winding.

6. The method of claim 1 , further comprising removing the support from the channel as the surgical fastener is deployed.

7. The method of claim 1 , further comprising removing the support from the channel after the surgical fastener is deployed.

8. The method of claim 1 , wherein inserting the support into the channel includes inserting the support through a proximal end of the channel.

9. The method of claim 1 , wherein the channel of the coil winding is an internal channel of the coil winding.

10. The method of claim 1 , wherein the channel of the coil winding is an external channel.

11. The method of claim 1 , wherein the coil winding comprises a magnesium alloy that is 5.0%-25.5% by weight dysprosium, 0.01%-5% by weight neodymium and/or europium, 0.1%-3.0% by weight zinc, and 0.1%-2.0% by weight zirconium.

12. A method of applying a surgical fastener, comprising:
inserting a support of a surgical fastener deployment system into a channel of the surgical fastener, wherein the channel is formed in and extending along at least a portion of a length of a coil winding of the surgical fastener, wherein the support is inserted through an opening formed in a head of the surgical fastener, wherein the coil winding is attached to and extends distally from the head, and wherein the coil winding is formed separately from the head;
deploying the surgical fastener with the surgical fastener deployment system while the support is at least partially located in the channel to support the surgical fastener and resist deformation of the surgical fastener during deployment.

13. The method of claim 12 , wherein the opening is radially offset from a central portion of the head.

14. The method of claim 12 , further comprising rotating the surgical fastener as it is deployed.

15. The method of claim 12 , further comprising removing the support from the channel as the surgical fastener is deployed.

16. The method of claim 12 , further comprising removing the support from the channel after the surgical fastener is deployed.

17. The method of claim 12 , wherein inserting the support into the channel includes inserting the support through a proximal end of the channel.

18. The method of claim 12 , wherein the channel of the coil winding is an internal channel of the coil winding.

19. The method of claim 12 , wherein the head is composed of a bioabsorbable material.

20. The method of claim 12 , wherein the coil winding comprises a magnesium alloy that is 5.0%-25.5% by weight dysprosium, 0.01%-5% by weight neodymium and/or europium, 0.1%-3.0% by weight zinc, and 0.1%-2.0% by weight zirconium.
