Abstract

A method of treating a patient includes determining a patient characteristic associated with the patient, determining a property value based at least in part on the patient characteristic, and determining a crosslinking parameter based at least in part on the property value.

Claims (39)

1 . A method of treating a patient, the method comprising:

determining a patient characteristic associated with the patient;

determining a property value based at least in part on the patient characteristic; and

determining a crosslinking parameter based at least in part on the property value.

2 . The method of claim 1 , further comprising:

effecting crosslinking of a bulk polymeric material of a device component based at least in part on the crosslinking parameter.

3 .- 6 . (canceled)

7 . The method of claim 2 , wherein effecting crosslinking of the device component includes irradiating the device component.

8 .- 9 . (canceled)

10 . The method of claim 1 , wherein determining the patient characteristic includes reviewing a patient medical file associated with the patient.

11 .- 17 . (canceled)

18 . A method of forming an implant device component, the method comprising:

determining a configuration of an implant device component; and

effecting crosslinking in a portion of a bulk polymeric material of the implant device component.

19 . The method of claim 18 , further comprising treating the implant device component.

20 . The method of claim 19 , wherein treating the implant device component includes sterilizing the implant device component.

21 . The method of claim 19 , wherein treating the implant device component includes annealing the bulk polymeric material of implant device component.

22 . The method of claim 19 , wherein treating the implant device component includes surface treating the implant device component.

23 . The method of claim 18 , wherein effecting crosslinking in the portion of the bulk polymeric material of the implant device component includes irradiating the portion of the bulk polymeric material.

24 . The method of claim 23 , wherein effecting crosslinking in the portion of the bulk polymeric material includes masking irradiation from a second portion of the bulk polymeric material.

25 . The method of claim 18 , wherein effecting crosslinking in the portion of the bulk polymeric material of the implant device component includes forming a temperature gradient in the bulk material.

26 . (canceled)

27 . The method of claim 18 , wherein the implant device component includes a nucleus of a spinal implant device.

28 . The method of claim 27 , wherein the portion is an anterior portion of the nucleus and wherein effecting crosslinking in the portion includes crosslinking the anterior portion of the nucleus.

29 . The method of claim 27 , wherein the portion is a posterior portion of the nucleus and wherein effecting crosslinking in the portion includes crosslinking the posterior portion of the nucleus.

30 . The method of claim 27 , wherein the portion is a center portion of the nucleus and wherein effecting crosslinking in the portion includes crosslinking the center portion of the nucleus.

31 .- 47 . (canceled)

48 . A prosthetic device comprising:

a component configured to be interposed between two osteal structures, the component formed of a bulk polymeric material including a first portion of the bulk polymeric material crosslinked to a greater extent than a second portion of the bulk polymeric material.

49 . The prosthetic device of claim 48 , wherein the two osteal structures include an inferior vertebra and a superior vertebra.

50 . The prosthetic device of claim 48 , wherein the component is configured to be interposed within a region surrounded by an annulus fibrosis and between an inferior vertebra and a superior vertebra.

51 .- 53 . (canceled)

54 . The prosthetic device of claim 48 , wherein the first portion is a center portion.

55 . The prosthetic device of claim 48 , wherein the first portion is an end portion.

56 . The prosthetic device of claim 48 , wherein the component has a maximum radius between about 3 mm and about 15 mm.

57 . (canceled)

58 . A kit comprising:

a prosthetic device comprising a bulk polymeric material; and

instructions relative to crosslinking the bulk polymeric material.
