We have designed and are fabricating the SideFireR laser optical fiber device incorporating a 99.95+% purity gold tip with a mirror which laterally reflects the beam at a 105 degree(s) angle to the optical fiber axis while closely maintaining the beam profile. The monolithic gold construction of the mirrored tip underlies the optical and thermal stability and the bicompatibility of the device during lasing in aqueous environments using up to 80 W of Nd:YAG 1.064 micrometers radiation. Current studies are being conducted to evaluate the use of this device in laser coagulation of the prostate as an alternative treatment to transurethral resection in treatment of benign prostatic hypertrophy.
