Abstract:
A myocardial revascularization system comprisinga laser energy source, an outer guide member providing access to a patient's heart, said guide member having a distal end, an optical fiber that is coupled to receive laser energy pulses from said source and is slidably located within said guide ember, said fiber having a distal end that is extendible from said distal end of said guide member, a drive motor connected to said fiber to automatically move said distal end of said optical fiber with respect to said distal end of said guide member, and a controller that controls said drive motor to automatically move said fiber in synchronism with firing of said laser energy, further comprising a drug delivery system that delivers drugs from said distal end of said catheter in response to a drug delivery signal, and a controller that controls said drive mechanism to move said fiber in synchronism with delivery of said drugs from said distal end of said catheter.
