A CATHETER SYSTEM FOR BYPASS SURGERY AND A METHOD FOR PREPARING A CATHETER SYSTEM FOR BYPASS SURGERY

摘要

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 predefined power value requirement; c) in case the measured ablation power is different from the predefined power value requirement, adjusting the ablation power of the pulsating light beam to meet the predefined power value requirement.
