A laser medical device for delivering energy to tissue to be treated. The device includes a laser energy transmitting conduit having a longitudinal axis, and has a proximal end for connection to a source of laser energy and a distal end from which laser energy transmitted by the conduit is emitted. A laser energy redirecting member is located adjacent the distal end of the conduit for redirecting the laser energy in a lateral direction with respect to the axis of the conduit, and a tissue contact member is provided adjacent the laser energy redirecting member. The tissue contact member has a transverse cross section of preselected shape and a longitudinal axis generally transverse to the axis of the conduit. The tissue contact member further has an input surface for receiving laser energy redirected by the laser energy redirecting member and transmitting the laser energy received from the laser energy redirecting member. The tissue contact member terminates in a tissue contact surface having a radius of curvature. The dimensions of the tissue contact member and the radius of curvature of the tissue contact surface are determined and structural such that laser energy is transmitted divergently therethrough and impinges upon the tissue contact surface in a substantially diffuse pattern.

Laterally-emitting laser medical device

A probe for medical use includes a tip portion having a light energy input region for receiving light energy from a light source and a predetermined light energy output region whereby tissue subtended by the region may be irradiated by the light energy. The tip portion consists essentially of light propagating material having inclusions distributed therein for interacting with the light energy to produce a predetermined light energy output pattern. The light propagating material is a light propagating inorganic compound.

A probe for medical use includes a tip portion having a light energy input region for receiving light energy from a light source and a predetermined light energy output region whereby tissue subtended by the region may be irradiated by the light energy. The tip portion consists essentially of light propagating material having inclusions distributed therein and generally throughout the tip portion between the light energy input region and the light energy output region for interacting with the light energy to produce a predetermined light energy output pattern. The light propagating material is a light propagating inorganic compound.

A medical device has a flexible light guide having a light energy input end adapted for connection to a source of light energy and a light energy output end. The output end outputs a beam of light energy. The device includes a tip for contacting tissue to be treated by the device and irradiating the tissue with light energy. The tip consists essentially of light-transmissive material and has a working region for contacting and irradiating the tissue to be treated. The working region of the tip includes sidewalls. The tip has a bore therein for receiving the output end of the light guide. The output end of the light guide is at least partially surrounded by the light-transmissive material, and is positioned relative to the light-transmissive material so as to define an interface therebetween. The interface is in proximity to and in thermally-conductive relationship with the working region of the tip so that heat energy generated at the interface significantly raises the temperature of the tip's working region. The interface is sufficiently distant from the working region of the tip so as to allow at least a portion of the beam of light energy to strike the sidewalls at first locations, reflect back into the tip and exit the tip at second locations different from the first locations.
