ERMI

What ERMI does

ERMI is a privately-held medical device company headquartered at 441 Armour Place NE in Atlanta, Georgia, that designs, manufactures, and distributes a suite of mechanical stretching devices intended to restore joint range of motion without surgery. Founded in 2001 by Thomas Paul Branch MD, Emeritus FAAOS, a sports medicine orthopedic surgeon with 35+ years of clinical experience, the company targets patients suffering from joint contractures and post-operative motion loss across six anatomical areas: shoulder, knee, elbow, ankle, great toe, and forearm/wrist. Its core technology, the Flexionater product line, consists of stand-alone, joint-specific mechanical devices that recreate the body alignment and force profiles used by physical therapists, enabling patient-controlled home stretching 24/7. The Therminater™ system extends the platform into ice-free precision cold and heat therapy for post-operative pain and swelling management.

The business model is direct durable medical equipment (DME) sales and rentals, with revenue generated through device provision supported by clinical staff. ERMI reaches customers through four channels: direct-to-consumer sales via its website and 877 phone line, healthcare provider referrals from physicians and physical therapists who prescribe and set up devices, Veterans Administration benefits coverage for eligible veterans, and Worker's Compensation programs for injured workers. Pricing is not publicly disclosed and is handled through direct sales contact, with patient billing processed through a dedicated portal. The company claims that 90% of patients using the Flexionater avoid motion restoring surgery.

ERMI operates as a small, bootstrapped organization with 11-50 employees, no disclosed institutional funding, no M&A history, and no executive leadership beyond its founder. Its geographic footprint is concentrated in the Southeast United States, and its brand identity (Flexionater, Therminater) is held as unregistered common-law marks. The company's growth posture is conservative, focused on deepening clinical evidence, expanding payer relationships, and incrementally extending its product portfolio rather than pursuing aggressive geographic or capital-driven scale.
