1. A laser catheter comprising:
- a catheter body having a central axis, a proximal end and a distal end, the catheter body having a lumen disposed between the proximal end and the distal end, the lumen having a distal opening at the distal end;
a light guide having a proximal end and a distal end, the light guide being at least partially disposed within the lumen and the distal end of the light guide extending from within the distal opening of the catheter body, wherein the light guide is configured to conduct light from a laser source at the proximal end to the distal end of the light guide;
a tip extending distally from the distal end of the catheter body, wherein the tip is disposed eccentrically to the light guide; and
an ultrasound imaging device disposed on the tip and positioned distally from the distal opening of the catheter body and the distal end of the light guide.

Abstract
Embodiments of the present invention include a laser catheter that includes a catheter body, a light guide, and a distal tip that extends beyond the exit aperture of the light guide. In some embodiments, an imaging device is disposed on the distal tip such that the imaging device is distal relative to the exit aperture of the light guide. In some embodiments, the imaging device can be gated to record images during and/or slightly beyond periods when the laser catheter is not activated.
