Abstract

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.

First claim

What is claimed is:

1. A tapered liquid light guide configured to increase energy density of light emanating from a laser catheter, the tapered liquid light guide comprising:
a proximal end including a proximal aperture having an inside diameter;
coupling means for mechanically and detachably coupling the proximal end to a distal end of the laser catheter;
a distal end including a distal aperture having an inside diameter, wherein the inside diameter of the distal aperture is…
