Half of men over age 51 — and 90 percent of men over 80 — suffer from non-cancerous benign prostatic hyperplasia (BPH). That means they have trouble urinating because of an enlarged prostate. Butterfly Medical has developed an innovative metal coil, shaped roughly like a butterfly, to stop BPH symptoms without drugs or surgery. Any urologist can insert the device in an outpatient procedure in less than 10 minutes.
