    • 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.
    • 本发明提供了一种治疗前列腺的方法和装置。 在优选实施例中,该装置包括具有第一轴向内腔和设置在轴的轴向内腔中的套筒的轴,该套筒具有带有开口远端的轴向通道。 套筒的轴向通道具有相对于轴向方向设置成一定角度的远端部分。 光纤被设置在套筒的轴向通道中,并且在其近端具有用于连接到激光器的连接器和用于组织穿透的尖锐远端。 光纤可以在套筒的轴向通道中向远侧推进,并且通过轴向通道的倾斜的远端部分朝向前列腺偏转。 因此,光纤穿透尿道并进入前列腺。 然后可以将激光能量直接通过光纤输送到前列腺中,以消融前列腺组织。 该装置还可以包括在轴中的光学装置,用于使轴远端可视化,以促进前列腺在所需位置的穿透。
