Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
112 words
Balloon catheter for the widening of passages in the human body, for example blood vessels, consisting of a tubular body that is connected on one side to the interior of a cylindrical balloon of pre-determined length and operational diameter, and which is connected on the other side to a pump unit, characterized in that one or more parts of the cylindrical balloon wall are provided with fixing means such that a wall strip is turned inward for the realizing of a first operational diameter, and which fixing means are arranged such that at a determined limit of pressure in the inflating medium they become detached to achieve a following larger operational diameter.
Claim 2
Dependent Claim
112 words
Balloon catheter for the widening of passages in the human body, for example blood vessels, consisting of a tubular body that is connected on one side to the interior of a cylindrical balloon of pre-determined length and operational diameter, and which is connected on the other side to a pump unit, characterized in that one or more parts of the cylindrical balloon wall are provided with fixing means such that a wall strip is turned inward for the realizing of a first operational diameter, and which fixing means are arranged such that at a determined limit of pressure in the inflating medium they become detached to achieve a following larger operational diameter.
Claim 3
Dependent Claim
27 words
Balloon catheter as claimed in claim 1, characterized in that the fixing means are arranged such that said wall strip extends in lengthwise direction of the balloon.
Claim 4
Dependent Claim
43 words
Balloon catheter as claimed in claim 1 and 2, characterized in that the fixing means are formed by one or more fixing welds between describing lines of parallel axis lying at a distance from each other on the cylindrical wall of the balloon.
Claim 5
Dependent Claim
37 words
Balloon catheter as claimed in claim 1 and 2, characterized in that the fixing means are formed by a strip having one or more weakened positions and attaching to the inside or outside of the cylinder wall.
Claim 6
Dependent Claim
40 words
Balloon catheter as claimed in claim 4, characterized in that the strip attaching to the outside is extended over the head end sides of the cylindrical balloon and the fold is filled with a substance, for example a medicinal substance.
Claim 7
Dependent Claim
38 words
Balloon catheter as claimed in claim 1-4, characterized in that the cylindrical balloon takes a step ped form as seen in lengthwise direction, and the portions of greater diameter are provided with one or more inwardly directed folds.
Claim 8
Dependent Claim
37 words
Balloon catheter as claims in claim 1-4, characterized in that the cylindrical balloon has one or more portions provided with one or more inwardly folds, so as to obtain a stepped form as seen in lengthwise direction.
