Radial medical laser delivery device
First Claim
1. A medical delivery system capable of emitting radiation with wavelengths between 190 nm and 16 um in one or more essentially directed, predetermined patterns, which comprises:
- (a) at least one solid optical fiber, having a core and a cladding on said core and said cladding having refractive index smaller than the core, having an input end suitably configured to connect to an appropriate radiation source and having a distal end in the proximity of which two or more grooves are penetrating into the core, said grooves having at least partial reflector capability so as to deflect radiation in one or more predetermined patterns; and
,(b) a cap placed over said at least one fiber at its distal end and over said two or more grooves.

Abstract
The present invention involves a medical delivery system capable of emitting radiation with wavelengths between 190 nm and 16 um in one or more essentially directed, predetermined patterns. It includes at least one solid optical fiber, having a core and a cladding on the core. The cladding has a refractive index smaller than the core, having an input end suitably configured to connect to an appropriate radiation source and having a distal end in the proximity of which two or more grooves are penetrating into the core. The gooves have at least partial reflector capability so as to deflect radiation thereto radially in one or more predetermined patterns. The invention also includes methods of performing medical procedures utilizing the aforesaid device.
