Formerly dba as Torix Medical, Zenflow develops minimally invasive devices to treat obstructive urinary symptoms related to benign prostatic hyperplasia (BPH or enlarged prostate) that will not require a painful or invasive procedure. With close ties to Stanford, the firm's first product is the Spring System, a technology that delivers a low-profile superelastic implant into the prostatic urethra. By providing therapy through a thin, flexible catheter with built-in visualization, the Spring System is designed to provide a simple procedure for the physician and the most patient-friendly solution on the market. This system is intended to permanently relieve BPH symptoms in a single procedure with fast recovery and minimal side effects.
