What Joline does

Joline GmbH & Co. KG is a privately held German medical technology company founded in 1999 and headquartered in Hechingen, Germany. The company designs, manufactures, and sells minimally invasive medical devices organized into four divisions: Dialysis (short-term, long-term, and pediatric catheters), Spine (kyphoplasty instruments, balloon catheters, and the Stop'n GO Quattroplasty double balloon system), Cardiology (KNIPSA endomyocardial biopsy forceps in 50 cm and 109 cm variants), and Stents & OEM (braided and laser-cut stents plus OEM contract manufacturing services). All products are developed and assembled by hand in Germany under an EN ISO 13485 quality system, with manufacturing capabilities spanning ISO Class 8 cleanroom plastic injection molding, laser welding/cutting, heat treatment, wire braiding, and electropolishing. The contract manufacturing division produces over 150,000 implants annually for external medical technology customers.

Joline generates revenue primarily through direct hardware sales of proprietary medical devices, complemented by OEM/contract manufacturing services. Go-to-market combines direct field sales in Germany and the United States (via wholly-owned subsidiary Joline Medical Inc., headquartered in Delaware with a Florida sales office) with a network of international distribution partners reaching more than 80 countries. Products are CE-marked, MDR-certified, and for kyphoplasty, FDA-approved (June 2020). Key end markets include dialysis clinics and nephrology departments, spine surgery and orthopedic hospitals, cardiology departments and heart centers, and other medical device OEMs seeking ISO 13485-certified manufacturing partners. The company is family-controlled through holding company Monsun GmbH, with the Sunnanväder family as principal shareholders and Christian Keller and Michael Eisenlohr serving as co-CEOs. No external institutional funding is disclosed, and the business is currently expanding capacity through a new 4,000 sqm headquarters in Hechingen expected to complete in Q2 2026.
