Company Overview
Zenflow, Inc. is a venture-backed medical device company that develops minimally invasive treatments for urinary obstruction caused by benign prostatic hyperplasia (BPH). Founded in 2014 out of the Stanford Byers Center for Biodesign, the company's flagship product is the Spring® System, a small, spring-like implant designed to be placed in a simple, office-based procedure. The device aims to provide durable symptom relief without requiring tissue removal, ablation, or piercing, thereby preserving sexual function. Zenflow is actively pursuing U.S. Food and Drug Administration (FDA) Pre-Market Approval (PMA) based on clinical data from over 300 patients, including its BREEZE pivotal trial. The company has raised significant capital to fund its path to commercialization, including a $24 million Series C financing round in late 2024.
