Prostiva RF Therapy Hand Piece Kit, REF 8929, Rx only, sterilized using Ethylene Oxide. The Prostiva RF Model 8929 Hand Piece Kit is the delivery system component of the Prostiva RF Therapy System. Prostiva RF Therapy delivers low-levels of radiofrequency (RF) energy directly into the hyperplastic tissue for the treatment of benign prostatic hyperplasia (BPH). The RF energy delivered by the system provides selective thermal ablation of prostate tissue to help reduce urethral constriction and relieve BPH voiding symptoms. The Prostiva RF Therapy System consists of the following major components: " Radio Frequency Generator " Hand Piece Kit " Telescope The Model 8929 Prostiva RF Therapy Hand Piece Kit contains the following single-use, disposable components: " One sterile Hand Piece with radio frequency cable (Model 8929) " One sterile Tubing System (Model 6101) " One non-sterile Return Electrode (Model 8934) The hand piece has two insulated electrode needles that deliver the radio frequency energy interstitially to the prostate. These needles are covered by insulating shields that localize the lesions within the prostate, protect the urethra from thermal damage, and eliminate collateral thermal damage. The Hand Piece stainless steel (SS) tube is inserted into the urethral canal up to the prostate with the aid of a telescope for visualization during the therapy. The Hand Piece features two insulated Nitinol needles inside the SS tube. The needles can be deployed (extended), at approximately a 90-degree angle from the SS tube, to a preset depth of between 12 mm and 22 mm (at 2 mm intervals). The needles inside the SS tube are deployed into, or retracted from the prostate, using the handle lever. RF energy is delivered through the needles to the prostate tissue. The RF energy creates molecular friction eventually resulting in tissue heating and cell death (therapy intent).
