ABSTRACT:
A laser delivery probe includes a silica optical fiber extending generally from the distal to the proximal end of the probe, a laser connector adapted to be secured to a laser source, and a handpiece. The laser connector forms the proximal end of the probe and the handpiece forms the distal end. The optical fiber provides optical paths through the laser connector and the handpiece and is secured by adhesive to both. A sheath having a lumen in which the silica optical fiber is disposed terminates proximally inside the laser connector and terminating distally inside the handpiece. The sheath is mechanically free-floating with respect to the optical fiber so that torque applied to the optical fiber is not directly applied to the sheath. The probe is used in an anti-curl laser delivery system which also includes a laser source to which the laser connector is removably secured. The sheath damps curling movements caused by rotation of the handpiece.
