Abstract
Abstract The invention provides a method for making an intraluminal stent, comprising the steps of: (a) forming a fibrin stent preform in a first mold cavity by polymerizing fibrinogen in said cavity; (b) placing said preform into a second mold cavity having a molding surface; and (c) compressing said preform against the molding surface of the second mold cavity.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
55 words
A method for making an intraluminal stent, comprising the steps of: (a) forming a fibrin stent preform in a first mold cavity by polymerizing fibrinogen in said cavity; (b) placing said preform into a second mold cavity having a molding surface; and (c) compressing said preform against the molding surface of the second mold cavity.
Claim 2
Dependent Claim
60 words
A method as claimed in claim 1 comprising the steps of: (a) polymerizing fibrinogen into a fibrin stent preform in said first mold cavity; (b) placing a balloon into said preform; (c) placing said balloon and preform into said second mold cavity; and (c) compressing said preform against the molding surface of said second mold cavity by expanding the balloon.
Claim 3
Dependent Claim
86 words
A method as claimed in claim 1 or claim 2 comprising the steps of: (a) placing a stent framework into said first mold cavity; (b) injecting fibrinogen and a fibrinogen-coagulating protein into said first mold cavity around the stent framework and allowing the fibrinogen to cure in said first mold cavity, thereby producing a fibrin stent preform comprising fibrin and said stent framework; (c) placing said preform into said second mold cavity; and (d) compressing said preform against the molding surface of said second mold cavity.
Claim 4
Independent Claim
37 words
A method as claimed in either of claims 1 and 2 wherein step (a) comprises placing a mixture of fibrinogen and a fibrinogen-coagulating protein into said first mold cavity and curing the mixture to produce said preform.
Claim 5
Independent Claim
23 words
A method as claimed in either of claims 3 and 4 wherein water is applied to said stent preform as the fibrinogen cures.
Claim 6
Independent Claim
21 words
A method as claimed in any one of claims 1 to 5 further comprising applying a buffer solution to said preform.
Claim 7
Dependent Claim
15 words
A method as claimed in claim 6 wherein said buffer solution comprises a crosslinking agent.
Claim 8
Independent Claim
19 words
A method as claimed in any one of claims 1 to 7 further comprising applying heparin to said preform.
Claim 9
Independent Claim
30 words
A method as claimed in any one of claims 1 to 8 wherein compression of said preform in said second mold cavity includes a slow outward expansion of said preform.
Claim 10
Independent Claim
26 words
A method as claimed in any one of claims 1 to 9 further comprising the step of mounting the compressed preform onto a balloon catheter balloon.
Claim 11
Independent Claim
27 words
A method as claimed in any one of claims 1 to 10 further comprising the step of applying a sterilizing dose of radiation to the compressed preform.
