CATHETER SYSTEM FOR BYPASS SURGERY AND A METHOD FOR PREPARING A CATHETER SYSTEM FOR BYPASS SURGERY
First Claim
1. A catheter system comprising:
- a laser catheter provided with a fibre bundle of optical fibres having distal ends defining a light emitting surface for emitting a pulsating light beam in a distal direction of the catheter;
a laser apparatus, comprising one or more lasers for supplying light to the optical fibres, wherein the system is configured to emit the pulsating light beam with an ablation power of at least 40 mJ/mm2 per pulse at the location of the light emitting surface; and
a stop surface extending around the fibre bundle of optical fibres and facing in the distal direction, the stop surface being arranged at a distance proximally from the light emitting surface.

Abstract
A catheter system is provided comprising a laser catheter with a fibre bundle of optical fibres emitting a light beam in the distal direction of the catheter and a laser apparatus, comprising one or more lasers for supplying light to the optical fibres. The catheter system is preset or adjusted for emitting a pulsating light beam with an ablation power of at least 40 mJ/mm2 per pulse at the location of a light emitting surface. A method for preparing such a catheter system is provided comprising the step of a) measuring said ablation power at the location of the light emitting surface; b) comparing the measured ablation power with a predefmed power value requirement; c) in case the measured ablation power is different from the predefmed power value requirement, adjusting the ablation power of the pulsating light beam to meet the predefined power value requirement.
