Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
162 words
Method for manufacturing a balloon catheter, comprising the providing of a piece of tube-like basic material, the manufacturing of a balloon member and the connecting of the balloon member with the basic material, wherein the manufacturing of the balloon member comprises the providing of a mould which in its turn has been provided with a mould cavity corresponding to an intended expanded form of the balloon member, turning at opposite ends into securing elements for the purpose of securing opposite end sections of a piece of tube-like semimanufacture inside the mould cavity, the receiving of the semimanufacture in the mould, the heating of the semimanufacture, the generating of a pressure difference between the inside and the outside of the semimanufacture as a result of which it expands into the balloon member arranged against the walls of the mould cavity, wherein the end sections of the semimanufacture on being received in the mould are turned over an angle in relation to each other.
Claim 2
Dependent Claim
25 words
Method as claimed in claim 1, wherein the tube-like semimanufacture is manufactured by means of extrusion and is pre-stretched before being received in the mould.
Claim 3
Dependent Claim
46 words
Method as claimed in one of the previous claims, wherein the intended expanded form is an intermediate form, and the heated, expanded balloon member is transferred to a second mould in which it is given its definite shape, and the cooling down of the balloon member.
Claim 4
Dependent Claim
26 words
Method as claimed in one of the previous claims, wherein the end sections are turned substantially over an angle of 270° in relation to each other.
Claim 5
Dependent Claim
32 words
Method as claimed in one of the previous claims, wherein the end sections are turned in such a direction, that the semimanufacture is twisted in the direction of a helix extending clockwise.
Claim 6
Dependent Claim
47 words
Balloon catheter manufactured with the method according to one of the previous claims, wherein the balloon member comprises a central section with on either side transition sections turning into tube-like end sections, of which at least one comprises ridges of material extending fan-shaped from the end section.
Claim 7
Dependent Claim
35 words
Balloon catheter as claimed in claim 6, wherein the central section and the transition sections are folded in pleads against the basic body and wherein the pleads substantially coincide with the fan-shaped ridges of material.
Claim 8
Dependent Claim
25 words
Balloon catheter as claimed in claim 6 or 7, wherein the ridges of material are substantially evenly distributed around the circumference of the transition section.
Claim 9
Dependent Claim
21 words
Balloon catheter according to one of the claims 6-8, wherein the transition section comprises between 5 and 15 ridges of material.
Claim 10
Dependent Claim
17 words
Balloon catheter as claimed in claim 9, wherein the transition section comprises some 10 ridges of material.
