Removal of body tissue with a long pulsed lasers is achieved such that sufficient energy to remove tissue is transmitted to the desired body without damaging an optical fiber transmitting the laser radiation. Pairs of pulses having the same or different wavelengths are coupled to more effectively remove tissue from the surgical site.

Pulsed laser system for the surgical removal of tissue

The present invention relates to systems and methods employed in the use of spectroscopy in the diagnosis of tissue. More particularly, it relates to the use of surface contact and needle probe devices having one or more optical fibers used to direct laser radiation onto tissue to be diagnosed, collecting radiation subsequently emitted by the tissue and delivering that radiation to a system for spectral analysis.

Devices and methods for optical diagnosis of tissue

A molded fiber-optic plug for retaining optical fibers in a fixed position within a laser catheter is disclosed in which an optically polished tubular moldable plug body is used to secure a plurality of optical fibers within a laser catheter.

Multi-fiber plug for a laser catheter

A method of forming an optical shield for a laser catheter is disclosed in which a rod of light transmissive material is optically polished and inserted into a tube of similar material and fused and the distal end of the rod is cut and the assembly is optically polished at the distal end.
