LASER CATHETER FOR BYPASS SURGERY AND ASSEMBLY COMPRISING SAID CATHETER
First Claim
1. A laser catheter for bypass surgery, wherein the distal part of the catheter is provided with:
- a tubular arrangement of optical fibres having distal ends defining a ring-shaped light emergence surface for emitting a tubular bundle of light beams in the distal direction of the catheter,a stop surface extending around the tubular arrangement of optical fibres and facing in the distal direction, the stop surface being arranged at a distance proximally from the light emergence surface;
wherein the light emergence surface slants at a slanting angle in the range of [20°
, 60°
] with respect to the longitudinal axis of the catheter.

Abstract
The invention is directed to a laser catheter (1) for bypass surgery, wherein the distal part (2) of the catheter (1) is provided with: a tubular arrangement (3) of optical fibres (4) having distal ends (5) defining a ring-shaped light emergence surface (6) for emitting a tubular bundle of light beams in the distal direction (D) of the catheter (1); and a stop surface (7) extending around the tubular arrangement (3) of optical fibres (4) and facing in the distal direction (D), the stop surface (7) being arranged at a distance (A) proximally from the light emergence surface (6). The light emergence surface (6) slants at a slanting angle (α) in the range of [20°, 60°] with respect to the longitudinal axis (8) of the catheter (1). The invention further relates to an assembly comprising such a catheter.
