Balloncatheter met lichtgeleider.

摘要

The invention relates to a catheter comprising a tube-like basic body with a distal and a proximal end and a balloon member arranged at the distal end. A light conductor extends from the proximal to the distal end which has close to the proximal end a light-absorbing end-section and close to the distal end a light-emitting end-section positioned inside the balloon member. The catheter comprises furthermore a light sensor, with a light-sensitive element situated inside the balloon member and a conductor conducting a light-dependent signal to the proximal end.
