Abstract
Abstract The invention relates to a catheter comprising a tube-like basic body with a distal and a proximal end, a balloon device arranged close to the distal end comprising at least one balloon member and carrying a radioactive conductor arranged in a pattern. The pattern comprises a number of coil shapes, each having a coil axis, and whereby the coil axes of the coil shapes can extend in different directions.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
129 words
A balloon catheter used for inflation of a lumen, said balloon comprising a shaft having proximal and distal ends and a lumen therethrough, and said shaft distal end attached to an inflatable balloon, said balloon having a lumen in communication with the lumen of said shaft, and said balloon having a reinforcing metallic layer molded therein; and further comprising said metallic layer being made of a radioactive material, so that upon inflation of said balloon, the radioactive metallic layer comes into the proximity of the walls of a body lumen; wherein said radioactive metallic layer is patterned in a coil shape; and wherein the pattern comprises a number of coil shapes, each comprising a coil axis, and wherein the coil axes of the coil shapes extend in different directions.
Claim 2
Dependent Claim
129 words
A balloon catheter used for inflation of a lumen, said balloon comprising a shaft having proximal and distal ends and a lumen therethrough, and said shaft distal end attached to an inflatable balloon, said balloon having a lumen in communication with the lumen of said shaft, and said balloon having a reinforcing metallic layer molded therein; and further comprising said metallic layer being made of a radioactive material, so that upon inflation of said balloon, the radioactive metallic layer comes into the proximity of the walls of a body lumen; wherein said radioactive metallic layer is patterned in a coil shape; and wherein the pattern comprises a number of coil shapes, each comprising a coil axis, and wherein the coil axes of the coil shapes extend in different directions.
