Laser energy delivery devices including laser transmission detection systems and methods

摘要

Laser energy delivery devices and methods are provided. A laser energy delivery device may include a housing, and a coupling is carried by the housing and adapted to couple to a laser energy generator. A sheath is carried by the housing, and the sheath includes a distal end adapted to be disposed in the subject. A plurality of transport members are carried by the sheath, and the plurality of transport members are adapted to receive laser energy at the coupling, transmit laser energy through the sheath, and deliver laser energy to the subject. A fluid-driven motor is carried by the housing and adapted to be driven upon receiving a fluid from a fluid source. A drive wire is carried by the sheath and eccentrically coupled to the distal end of the sheath, and the drive wire is adapted to be rotatably driven by the fluid-driven motor and rotates to eccentrically rotate the distal end of the sheath.
