Abstract

The invention provides a method and apparatus for treatment of the prostate. In a preferred embodiment, the apparatus includes a shaft having a first axial lumen and a sleeve disposed in the axial lumen of the shaft, the sleeve having an axial passage with an open distal end. The axial passage of the sleeve has a distal portion disposed at an angle relative to the axial direction. An optical fiber is disposed in the axial passage of the sleeve and has a connector at its proximal end for connection to a laser and a sharp distal tip for tissue penetration. The optical fiber may be advanced distally in the axial passage of the sleeve and deflected toward the prostate by the angled distal portion of the axial passage. The optical fiber thus penetrates out of the urethra and into the prostate. Laser energy may then be delivered through the optical fiber directly into the prostate for ablation of prostatic tissue. The apparatus may further include optical means in the shaft for visualizing distally of the shaft to facilitate penetration of the prostate at the desired site.
