Embodiment Construction

[0062] FIGS. 1 a and 1 b show a longitudinal section and a bottom view of the distal region 23 of the laser catheter 1 . The laser catheter 1 has a housing 2 which meets the typical requirements for use in the medical field, such as easy sterilization, high flexibility and material compatibility. The housing 2 surrounds a tubular bundle of optical fibers 3 arranged in two layers, in a preferred embodiment two concentric circles. The proximal end 21 of the optical fiber 3 is connected or can be connected to the laser generator 4 in such a way that the laser radiation (laser) generated by the laser generator can be delivered to the optical fiber 3, which is then Laser energy will be directed from the proximal fiber end 21 to the distal fiber end 22 . An inner tubular shell 5 surrounds a bore 6 which is connected at its proximal end 20 to a low pressure source 7 . In the distal region of the laser catheter 1 is an outer circumferential widening element 8 which has a ring-shaped...

Abstract

The invention relates to a laser catheter for bypass surgery. The laser catheter comprises: a tubular arrangement comprising a tubular bundle of optical fibres having distal ends defining an emitting surface for emitting laser radiation in the distal direction of the catheter; at the distal end of the catheter, a channel extending in axial direction of the catheter and defined by the inside of the tubular arrangement, which channel is connectable to a suction source; and a grid element arranged inside the channel at a distance proximally from the emitting surface, which grid extends in transverse direction of the catheter across the channel. The laser catheter further comprises a narrowing arranged inside the channel and, viewed in axial direction of the catheter, between the emitting surface and the grid.

Description

technical field [0001] The present invention relates to a laser catheter for use in bypass surgery, wherein the laser catheter comprises: a tubular arrangement comprising a tubular bundle of optical fibers having a distal end defining an emitting surface for use in the distal direction of the catheter emitting laser radiation; at the distal end of the catheter, a channel extending in the axial direction of the catheter and defined by the interior of the tubular arrangement, the channel being connectable to a suction source; and emitting A grid element is arranged at a distance inside the channel, the grid element extending in a transverse direction across the conduit of the channel. The invention also relates to an assembly comprising such a catheter on the one hand and a ring member and / or a graft vessel and / or a suction source and / or an excimer laser source on the other hand. The laser catheter according to the invention as well as the assembly according to the invention ca...
