Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
140 words
Method for manufacturing from foil material a double-walled sleeve-formed stent closed at both ends and having curable material enclosed between the walls, characterized by: - forming from foil material a single-walled basic sleeve with a diameter related to the diameter of the stent to be formed, - folding back into itself a portion of this single sleeve so as to form a double-walled sleeve portion wherein the distance between both spaced apart walls is related to the length of the stent to be formed, and with an adjoining single-walled sleeve portion, - arranging curable material in the space between both walls of the double-walled sleeve portion, - folding back the single-walled sleeve portion extending beyond the end of the double-walled sleeve portion over the outer wall of the double-walled sleeve portion and connecting said folded-back portion to said outer wall.
Claim 2
Dependent Claim
35 words
Method according to claim 1, characterized in that the step of folding back the extending single sleeve portion is executed while using a guiding member enclosing the double-walled sleeve portion and being movable relative thereto.
Claim 3
Dependent Claim
53 words
Method according to claims 1-2, characterized in that the step of folding back into itself a portion of the single sleeve is executed while using a guiding edge enclosing said sleeve and pulling the single sleeve outwardly over said edge, over a distance related to the length of the stent to be formed.
Claim 4
Dependent Claim
52 words
Method according to claims 1-2, characterized in that the step of folding back into itself of the single sleeve is executed while using a guiding edge situated within said sleeve and pulling the single sleeve inwardly over said edge, over a distance related to the length of the stent to be formed.
Claim 5
Dependent Claim
64 words
Method according to claims 1-4, characterized in that the single sleeve portion is formed by: - folding double a sheet of foil material, - welding together both sheet portions at a distance of the fold, determined by the desired sleeve diameter, according to a line parallel to the fold, - cutting the material along the weld at the side facing away from the fold.
Claim 6
Dependent Claim
27 words
Method according to claims 1-5, characterized in that the curable material arranged in absorbent material is supplied over the length in a more or less thick layer.
Claim 7
Dependent Claim
9 words
Stent obtained with the method according to claims 1-6.
