Zephyr Surgical Implants

Zephyr Surgical Implants is a private Swiss medical device company focused on implantable prosthetic devices for urology, andrology, gynecology, and gender-affirming surgery. The company develops, manufactures, assembles, and tests its products in Switzerland and markets them internationally through subsidiaries and distributors. Its core commercial portfolio includes the ZSI 375 PF artificial urinary sphincter and multiple penile implant systems, including products designed for cisgender male erectile dysfunction and transgender men after phalloplasty or metoidioplasty. The company positions itself as a specialist in implantable solutions for urinary incontinence and erectile restoration rather than a drug developer. ZSI appears to be a commercial-stage, family-run device manufacturer with global distribution across more than 70 countries.
