Abstract
A heart catheter for endocardial laser irradiation of arrhythmogenic substrates is disclosed. The heart catheter comprises a catheter hose enclosing a flushing channel and an optical fiber, and a distal catheter tip. The catheter tip comprises: a main body surrounding a frontal passageway for laser light emitted from the optical fiber and for a flushing liquid provided via the flushing channel; a fiber mount inwardly extending from the main body, for centrally mounting the optical fiber; and connecting channels segmenting the fiber mount in a circumferential direction and connecting the flushing channel with the frontal passageway. Since the frontal passageway narrows, at least within a longitudinal section thereof, towards the distal end of the catheter tip, the flushing liquid can flow in an even and laminar manner through the passageway, thereby keeping blood out of the irradiation field and away from the optical fiber.
