Abstract
Abstract The catheter comprises: a tube-like basic body having a distal end, a distal end section, a proximal end and two balloons mounted to the distal end section. One of the balloons is a dilatation balloon and the other of the balloons is used for the purpose of carrying and expanding a stent. Also, one of the two balloons is more pliable than the other of the two balloons. The balloons possess varying degrees of pliability. The different degrees of pliability can be a result of the fact that the wall thickness of the balloons varies.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
94 words
A catheter comprising a tube-like basic body having a distal end, a distal end section, a proximal end and two balloons mounted to said distal end section, one being a distal balloon and one being a proximal balloon in said distal end section; one of said distal and proximal balloons being a dilatation balloon and the other of said proximal and distal balloons being used for the purpose of carrying and expanding a stent; and one of said distal and proximal balloons being more pliable than the other of said proximal and distal balloons.
Claim 2
Dependent Claim
94 words
A catheter comprising a tube-like basic body having a distal end, a distal end section, a proximal end and two balloons mounted to said distal end section, one being a distal balloon and one being a proximal balloon in said distal end section; one of said distal and proximal balloons being a dilatation balloon and the other of said proximal and distal balloons being used for the purpose of carrying and expanding a stent; and one of said distal and proximal balloons being more pliable than the other of said proximal and distal balloons.
Claim 3
Dependent Claim
70 words
The catheter of claim 1 wherein said basic body comprises an outer tube-like element having a lumen inside of which an inner tube-like element has been received, thereby forming an annular space between said tube-like elements, a lumen of the inner tube-like element being connected with said distal balloon and the annular interspace between the inner tube-like element and the outer tube-like element member being connected with said proximal balloon.
Claim 4
Dependent Claim
49 words
The catheter of claim 1 wherein said two balloons are arranged close to said distal end and are connected with a source of fluid medium via couplings members at said proximal end and via said lumens in said basic body and wherein the pliability of said two balloons varies.
Claim 5
Dependent Claim
50 words
The catheter of claim 1 wherein said distal and proximal balloons each have a wall with a given wall thickness and wherein the different degrees of pliability between said distal and proximal balloons are a result of the fact that the wall thickness of said distal and proximal balloons varies.
Claim 6
Dependent Claim
34 words
The catheter of claim 1 wherein the different degrees of pliability between said distal and proximal balloons are a result of the fact that said distal and proximal balloons are manufactured of different materials.
Claim 7
Dependent Claim
26 words
The catheter of claim 1 wherein said distal balloon is more pliable than said proximal balloon which is used for the purpose of expanding a stent.
Claim 8
Dependent Claim
20 words
The catheter of claim 1 wherein the less pliable balloon has a greater pressure resistance than the more pliable balloon.
