Abstract
A laser energy delivery catheter emits energy laterally relative to the longitudinal axis of the catheter. The catheter distal end is a cylindrical housing provided with a sidewall aperture. Within the housing is mounted a prism spaced from the distal end of a fiber optic. The refractive index of the prism is higher than the refractive indices of the fiber optic and the coupling liquid medium. A liquid medium is utilized to cool the device when in use, and may also be utilized to optically couple the fiber optic and the prism. The catheter can be configured as a rigid or semi-rigid, hand held surgical instrument, or as a flexible device that can be inserted into body lumens through an endoscope.
