Laser Surgical Device

US Patent:

5746738, May 5, 1998

Filed:

Nov 20, 1996

Appl. No.:

8/751428

Inventors:

David J. Cleary - Alexandria VA
Hyung S. Ryu - Washington DC

Assignee:

Cleary & Oxford Associates - Alexandria VA

International Classification:

A61B 1736

US Classification:

606 15

Abstract:

In a surgical catheter or probe, an array of multiple surgical laser beams are directed such that several laser beams intersect at a precise point on, or in, the body of a surgical patient. The power density of the laser energy of the intersecting beams at the point of intersection is sufficient to alter or ablate the patient's tissue, bone or fluid. The energy of the individual laser beams before or after the point of intersection is not sufficient to injure the body of the patient. The apparatus may be embodied as a catheter or probe for an endoscope, or can be used in a separate mechanism such that the laser beams enter the surgical patient at different locations but intersect at a point within the patient.
