A light-diverting catheter tip is provided according to embodiments disclosed herein. The light-diverting catheter tip may be coupled with the distal tip of a laser catheter and divert at least a portion of the light exiting the distal tip of the laser catheter such that the spot size of the laser beam on an object after exiting the catheter tip is larger than the spot size of the light entering the catheter without the catheter tip. The catheter tip may be removably coupled with the catheter or constructed as part of the catheter. In other embodiment, the catheter tip may conduct fluid and/or divert fluid at the tip of the laser catheter.

Liquid light-guide catheter with optically diverging tip

A catheter tip is provided according to various embodiments of the disclosure. The catheter tip may comprise a distal end, a proximal end, and tubular walls. The distal end includes a distal aperture with a distal inside diameter, and the proximal end includes a proximal aperture with a proximal inside diameter. The proximal inside diameter may be greater than the distal inside diameter. The proximal end comprises attachment means configured to couple the proximal end with a distal end of a laser catheter. The tubular walls may include at least an inside taper from the proximal end to the distal end such that the inner tubular walls generally taper from the proximal inside diameter to the distal inside diameter. Moreover, the tubular walls may be configured to direct at least a liquid medium, for example, a biocompatible solution, toward the distal aperture.

Tapered liquid light guide

A light-diverting catheter tip is provided according to embodiments disclosed herein. The light-diverting catheter tip may be coupled with the distal tip of a laser catheter and divert at least a portion of the light exiting the distal tip of the laser catheter such that the spot size of the laser beam on an object after exiting the catheter tip is larger than the spot size of the light entering the catheter without the catheter tip. The catheter tip may be removably coupled with the catheter or constructed as part of the catheter. In other embodiments, the catheter tip may conduct fluid and/or divert fluid at the tip of the laser catheter.
