The Medtronic TUNA (Transurethral Needle Ablation) Therapy is
a minimally invasive treatment for patients with lower urinary tract
symptoms due to benign prostatic hyperplasia (BPH). The
Medtronic Prostiva RF System uses precisely focused radio
frequency energy to ablate prostate tissue, which helps to reduce
the constriction of the urethra and relieve BPH voiding symptoms.
The Medtronic Prostiva RF Therapy is clinically equivalent to the
Medtronic TUNA (Transurethral Needle Ablation) Therapy. The
Medtronic Prostiva RF Therapy and System represent a new
version of the radio frequency generator and hand piece that are
used for the same transurethral needle ablation procedure for
treating benign prostatic hyperplasia.
The Prostiva RF System is indicated for the treatment of
symptoms due to urinary outflow obstruction secondary to benign
prostatic hyperplasia (BPH) in men over the age of 50 with
prostate sizes between 20 and 50 cm
