Biological repair material compatible with biological tissue adhesive
An object of the present invention is to provide a means for improving the affinity of an in vivo embedded material such as an artificial blood vessel or an artificial dura mater with a tissue adhesive, so as to quickly prevent the leakage of the blood or spinal fluid. The present invention provides a polymeric material used in combination with a tissue adhesive, which comprises carbon or silicon as a constitutional element, and at least a portion of the surface of which is modified by ion bombardment.
1. A method for improving affinity with a fibrin glue of a polymeric material comprising carbon or silicon as a constitutional element, the polymeric material comprising expanded polytetra-fluoroethylene or silicone, comprising irradiating at least a portion of a surface of the expanded polytetra-fluoroethylene or silicone with ions at a dose (φ) of 1×10 12 ≦φ≦1×10 16 ions/cm 2 to form an ion-modified expanded polytetra-fluoroethylene or silicone; and applying the fibrin glue to the irradiated at least a portion of a surface of the expanded polytetra-fluoroethylene or silicone, wherein the ion is He + , Ne + , Ar + , or Kr + .
2. The method according to claim 1 wherein the ion-modified expanded polytetra-fluoroethylene or silicone includes a non-irradiated portion and the non-irradiated surface is placed into contact with dura mater.
3. The method according to claim 1 wherein the expanded polytetra-fluoroethylene or silicone is an artificial dura mater, an artificial blood vessel, a patch for the heart or blood vessel, or a surgical suture.
4. The method according to claim 1 wherein the expanded polytetra-fluoroethylene or silicone comprises expanded polytetra-fluoroethylene.
5. The method according to claim 1 wherein the expanded polytetra-fluoroethylene or silicone is an artificial dura mater.
6. The method according to claim 1 wherein the irradiating at least a portion of a surface of the expanded polytetra-fluoroethylene or silicone comprises irradiating with ions at a dose (φ) of 1×10 13 ≦φ≦1×10 15 ions/cm 2 .
7. The method according to claim 1 wherein the expanded polytetra-fluoroethylene or silicone comprises silicone.
8. The method according to claim 2 wherein the expanded polytetra-fluoroethylene or silicone comprises expanded polytetra-fluoroethylene.
9. The method according to claim 2 wherein the expanded polytetra-fluoroethylene or silicone comprises silicone.
10. The method according to claim 3 wherein the expanded polytetra-fluoroethylene or silicone comprises expanded polytetra-fluoroethylene.
11. The method according to claim 3 wherein the expanded polytetra-fluoroethylene or silicone comprises silicone.
12. The method according to claim 5 wherein the expanded polytetra-fluoroethylene or silicone comprises expanded polytetra-fluoroethylene.
13. The method according to claim 5 wherein the expanded polytetra-fluoroethylene or silicone comprises silicone.
14. The method according to claim 6 wherein the expanded polytetra-fluoroethylene or silicone comprises expanded polytetra-fluoroethylene.
15. The method according to claim 6 wherein the expanded polytetra-fluoroethylene or silicone comprises silicone.
