A side-firing laser system with a standoff catheter includes an optical fiber configured to emit therapeutic laser radiation in a direction generally transverse to an axis of the fiber; and a catheter through which the optical fiber is inserted during a surgical procedure. The catheter includes a transparent end section through which the therapeutic laser radiation passes to vaporize tissue outside the catheter, an open distal end to permit exit of irrigation fluid from the catheter, and an opening in a side of the end section, the opening having dimensions that are approximately equal to or less than cross-sectional dimensions of the therapeutic laser radiation. When the fiber is moved to a position at which the therapeutic laser radiation passes through the opening, the laser radiation causes coagulation or vaporization of tissues.

A protective structure for the distal treatment end of a surgical laser fiber inserted into a patient through a scope includes uniformly-spaced ruler or scale markings that are visible through the scope and that enable the size of an object within the field of view of the scope to be precisely determined.

Fiber tip protective structure with scale indicator

A distal end of an optical fiber may be protected by a variety of alternative protective caps, tips, and/or sleeves. In one example, a generally cylindrical soft tip is arranged to fit over the end of the fiber, and to compress in an axial direction when pressed against a stone to allow a recessed tip of the fiber to contact the stone or to be maintain a minimum spacing between the fiber tip and the stone and thereby limit erosion of the fiber tip.
