A laser illuminator emitting a circular profile of substantially uniform intensity is presented. The laser illuminator may include a heat sink configured to optically couple to a laser light source. The heat sink may include a beam dump cavity configured to absorb light from the laser light source, and a circularizer aperture having a cylindrical, flat-top opening and being configured to shape a portion of laser light emitted from the laser light source to exit the heat sink. The laser illuminator may also include a collimation lens configured to collect the light exited from the heat sink and provide a focused beam of light, and a scatter clean-up aperture optically coupled to the collimation lens. The scatter clean-up aperture may be configured to absorb scatter laser light rays, and provide from the focused beam of light an output beam of light comprising a circular profile of substantially uniform intensity.

Adjustable laser illumination pattern

Single beam aiming laser

An adjustable beam illuminator may provide a beam of light with an output cone angle that is adjustable (e.g., continuously adjustable) from small output angles (substantially collimated beam, 'spot' mode) to larger output angles providing 'flood' illumination. The illuminator may emit infrared light, for example.

Prostate treatment using fluid stream to resect prostate tissue, thereby relieving symptoms of conditions such as BPH, prostatitis, and prostatic carcinoma. A device having a fluid delivery element is positioned within a lumen of the urethra within the prostate. A fluid stream is directed outwardly from the fluid delivery element toward a wall of the urethral lumen. The fluid delivery element is moved to scan the fluid stream over the wall to remove a volume of tissue surrounding the lumen. The fluid may be combined with therapeutically active substances or with substances that increase resection efficiency. Fluid force may be adjusted to provide selective tissue resection such that soft tissue is removed while harder tissue is left undamaged. In order to gain a working space within the urethra, another fluid may be introduced to insufflate the urethra in the region of treatment.

A light pointer (e.g., laser pointer) comprises an optical fiber light source. Optionally, the output beam provided by the pointer may be adjustable from small output angles (substantially collimated beam, 'spot' mode to larger output angles providing 'flood' illumination. The light pointer may emit infrared light, for example.
