Claim 4
Dependent Claim
15 words
A suture component according to claim 3 wherein said suture component comprises a nonabsorbable suture.
Claim 5
Dependent Claim
27 words
A suture material according to claim 5 wherein said nonabsorbable suture component comprises Dacron and said aluminum coating has a thickness of between 10 to 20 microns.

Dependent Claim
15 words
A suture material according to claim 5 wherein said nonabsorbable suture component comprises stainless steel.
Claim 8
Dependent Claim
131 words
A surgical material for use in a patient as ligatures and as sutures for closing wounds, said surgical material comprising: an elongated core of surgical suture material; and a coating on said core of a different material, said coating extending over a substantial portion of the surface of said core, said coating material being selected from the group consisting of substantially pure aluminum and substantially pure magnesium; said coating being adapted to beneficially chemically react with the tissues in the vicinity of said surgical material, said coating being of such thickness as to increase the rate of fibrosis in said tissues at a controlled rate, said coating being dissipated by said chemical reaction and the residual fibrotic reaction due to said coating materials ceasing when said coating has been completely dissipated.

Dependent Claim
33 words
The combination according to claim 10 wherein said suture component comprises a nonabsorbable material which can be left as a supporting element for the wound tissues after said coating has been completely dissipated.
Claim 11
Dependent Claim
20 words
The combination according to claim 11 wherein said aluminum coating has a thickness of between about 6 to 40 microns.
Claim 12
Dependent Claim
32 words
A suture component and coating according to claim 7 wherein said suture component is resorbable in the wound and said coating protects said component against resorption until said coating has been dissipated.
