Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
81 words
A method for applying a covering layer to a stent comprising: (a) forming a tube made out of an elastomeric polymerisable composition; (b) radially contracting the stent; (c) inserting into the tube at least a portion of the stent; and (d) radially expanding at least the portion of the stent in the tube or allowing at least the portion of the stent to expand in the tube, and chemically bonding at least the portion of the stent and the tube together.
Claim 2
Independent Claim
81 words
A method for applying a covering layer to a stent comprising: (a) forming a tube made out of an elastomeric polymerisable composition; (b) radially contracting the stent; (c) inserting into the tube at least a portion of the stent; and (d) radially expanding at least the portion of the stent in the tube or allowing at least the portion of the stent to expand in the tube, and chemically bonding at least the portion of the stent and the tube together.
Claim 3
Independent Claim
120 words
A method for applying a covering layer to a stent comprising: (a) forming a tube made out of an elastomeric polymerisable composition, the tube having an inside; (b) coating the inside of the tube with an adhesive medium; (c) providing a stent having at least one portion along its length, and radially contracting the stent; (d) inserting into the tube at least one portion of the stent; (e) radially expanding the at least one portion of the stent in the tube or allowing the at least one portion of the stent to expand in the tube; and (f) curing the adhesive medium between the inside of the tube and the at least one portion of the stent in the tube.
Claim 4
Independent Claim
120 words
A method for applying a covering layer to a stent comprising: (a) forming a tube made out of an elastomeric polymerisable composition, the tube having an inside; (b) coating the inside of the tube with an adhesive medium; (c) providing a stent having at least one portion along its length, and radially contracting the stent; (d) inserting into the tube at least one portion of the stent; (e) radially expanding the at least one portion of the stent in the tube or allowing the at least one portion of the stent to expand in the tube; and (f) curing the adhesive medium between the inside of the tube and the at least one portion of the stent in the tube.
Claim 5
Independent Claim
136 words
A method for applying a covering layer to a stent comprising: (a) forming a tube from an elastomeric polymerisable composition, the tube having an inside; (b) preparing an elastomeric composition dissolved in a solvent; (c) coating the inside of the tube with the elastomeric composition dissolved in the solvent; (d) providing a stent having at least one portion along its length, and radially contracting the stent; (e) inserting into the tube at least one portion of the stent; (f) radially expanding the at least one portion of the stent in the tube or allowing the at least one portion of the stent to radially expand in the tube; (g) evaporating the solvent; and (h) polymerizing the elastomeric composition between the inside of the tube and the at least one portion of the stent in the tube.

Claim 7
Independent Claim
92 words
A method for covering a stent comprising: (a) forming a polymeric tube having an inner surface; (b) inserting a contracted stent into the tube, the stent having an inner surface and an outer surface; (c) radially expanding the stent or allowing the stent to radially expand in the tube so that at least part of the stent outer surface makes contact with at least part of the tube inner surface; and (d) chemically bonding at least a part of the outer surface of the stent to the inner surface of the tube.
Claim 8
Independent Claim
92 words
A method for covering a stent comprising: (a) forming a polymeric tube having an inner surface; (b) inserting a contracted stent into the tube, the stent having an inner surface and an outer surface; (c) radially expanding the stent or allowing the stent to radially expand in the tube so that at least part of the stent outer surface makes contact with at least part of the tube inner surface; and (d) chemically bonding at least a part of the outer surface of the stent to the inner surface of the tube.
Claim 9
Independent Claim
67 words
A method for covering a stent comprising: (a) forming a polymeric tube having an inner surface; (b) coating the inner surface of the tube with an adhesive medium; (c) inserting a contracted stent into the tube; (d) radially expanding the stent in the tube or allowing the stent to radially expand in the tube; and (e) curing the adhesive medium or allowing the adhesive medium to cure.
Claim 10
Independent Claim
67 words
A method for covering a stent comprising: (a) forming a polymeric tube having an inner surface; (b) coating the inner surface of the tube with an adhesive medium; (c) inserting a contracted stent into the tube; (d) radially expanding the stent in the tube or allowing the stent to radially expand in the tube; and (e) curing the adhesive medium or allowing the adhesive medium to cure.
