Abstract
Abstract A device for implanting into a body vessel in the region of a vessel branching has a radially expandable stent formed as a hollow cylindrical element and provided with an increased radial opening, and a balloon catheter on which the stent is pre-mounted for implanting in the vessel, the balloon catheter having a hollow chamber for passage of a guiding wire so that it exits in a center of the increased opening from the hollow chamber and the stent.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
118 words
A device for implanting a body vessel in the region of a vessel branching, comprising a radially expandable stent formed as a hollow cylindrical element and provided with an increased radial opening; and a balloon catheter on which said stent is premounted for implanting in the vessel, said balloon catheter having a hollow chamber for passage of a guiding wire so that it exits in a center of said increased opening from said hollow chamber and said stent, said balloon catheter being provided with another longitudinal chamber extending along a longitudinal axis of said catheter and formed so that a further guiding wire extends through said other longitudinal chamber and exits at a tip of said balloon catheter.
Claim 2
Independent Claim
118 words
A device for implanting a body vessel in the region of a vessel branching, comprising a radially expandable stent formed as a hollow cylindrical element and provided with an increased radial opening; and a balloon catheter on which said stent is premounted for implanting in the vessel, said balloon catheter having a hollow chamber for passage of a guiding wire so that it exits in a center of said increased opening from said hollow chamber and said stent, said balloon catheter being provided with another longitudinal chamber extending along a longitudinal axis of said catheter and formed so that a further guiding wire extends through said other longitudinal chamber and exits at a tip of said balloon catheter.
Claim 3
Dependent Claim
33 words
A device as defined in claim 1, wherein said stent is dilatable so that after a dilation of said stent, said balloon catheter is pullable along said guiding wires out of the vessel.
Claim 4
Dependent Claim
24 words
A device as defined in claim 1, wherein said further guiding wire is guided through said other hollow chamber out of said increased opening.
Claim 5
Dependent Claim
47 words
A device as defined in claim 3, wherein said balloon catheter has a balloon portion, said other hollow chamber for said further guiding wire guided out of said increased opening being formed by a pipe mounted on an outer surface of said balloon portion of said catheter.
Claim 6
Dependent Claim
44 words
A device as defined in claim 3, wherein said catheter has a balloon portion which is formed as a double-walled balloon, said other hollow chamber for guiding said further wire from said increase opening being formed as an intermediate chamber of said double-wall balloon.
Claim 7
Dependent Claim
51 words
A device as defined in claim 3, wherein said balloon catheter has a balloon portion, said other hollow chamber for guiding said further wire out of said increased opening being formed as an intermediate chamber between said balloon portion and a stretchable hose piece which is pulled onto said balloon portion.
Claim 8
Dependent Claim
33 words
A device as defined in claim 1, wherein said balloon catheter is composed of three coaxial hoses arranged so that two inwardly located hoses form said hollow chambers for receiving said guiding wires.
Claim 9
Dependent Claim
20 words
A device as defined in claim 1, wherein said stent is composed of a pipe and has a multi-cellular wall.
Claim 10
Dependent Claim
15 words
A device as defined in claim 1, wherein said stent is bent from a wire.
Claim 11
Dependent Claim
28 words
A device as defined in claim 1, wherein said stent is formed as a wire selected from the group consisting of structured wire, knitted wire and twisted wire.
Claim 12
Dependent Claim
19 words
A device as defined in claim 1, wherein said increased opening is arranged in a center of said stent.
Claim 13
Dependent Claim
17 words
A device as defined in claim 1, wherein said increased opening is arranged eccentrically on said stent.
Claim 14
Independent Claim
119 words
A device for implanting into a body vessel in the region of a vessel branching, comprising a radially expandable stent formed as a hollow cylindrical element and provided with an increased radial opening; a balloon catheter on which said stent is pre-mounted for implanting in the vessel, said balloon catheter having a first hollow chamber and another longitudinal chamber extending along a longitudinal axis of said catheter; and guiding means including a first guiding wire passing through said first hollow chamber so that it exits in a center of said increased opening from said hollow chamber and said stent, and a further guiding wire extending through said other longitudinal chamber and exiting at a tip of said balloon catheter.
Claim 15
Independent Claim
119 words
A device for implanting into a body vessel in the region of a vessel branching, comprising a radially expandable stent formed as a hollow cylindrical element and provided with an increased radial opening; a balloon catheter on which said stent is pre-mounted for implanting in the vessel, said balloon catheter having a first hollow chamber and another longitudinal chamber extending along a longitudinal axis of said catheter; and guiding means including a first guiding wire passing through said first hollow chamber so that it exits in a center of said increased opening from said hollow chamber and said stent, and a further guiding wire extending through said other longitudinal chamber and exiting at a tip of said balloon catheter.
