Oldelft Ultrasound

What Oldelft Ultrasound does

Oldelft Ultrasound is a Netherlands-headquartered OEM supplier of medical ultrasound transducers, founded in 1939 as an optics company and active in ultrasound probe development since the 1980s. Operating as Oldelft B.V. from Delft with approximately 90 employees, the company designs and manufactures transesophageal echocardiography (TEE) probes for integration into the ultrasound systems of all major global equipment manufacturers, including GE Healthcare, Philips, Siemens Healthineers, Canon, Samsung, Hitachi, and Mindray. The company was the first to deliver a commercial TEE solution in 1988 and currently offers both a complete 2D TEE portfolio (neonatal, pediatric, and adult probes) and proprietary 4D ultrasound solutions.

The company's core technology is built around the USX platform, a proprietary 4D ultrasound imaging architecture powered by an in-house designed ASIC. This platform supports a family of miniaturized 4D probes - including the world's first mini 4D TEE probes for pediatric patients as small as 5 kg, a 4D ICE transducer fitting into a 12 French catheter, and a next-generation adult 4D TEE premium probe with 8 mm shaft and 3,072 elements. Differentiating technology features include state-of-the-art matrix array acoustic elements, advanced thermal management for safe prolonged tissue contact, multi-directional articulation (2-way and 4-way), and ASIC-driven scalability across product lines.

Oldelft generates revenue through direct B2B hardware sales of transducers to OEM partners under non-publicly-disclosed commercial terms. Pricing is quote-based via direct contact ([email protected]), and sales inquiries are managed through prototype requests and OEM integration projects. Distribution is exclusively OEM-embedded: probes are integrated into OEM ultrasound systems and resold to hospitals and clinicians worldwide, with Oldelft serving Europe, North America, and the Asia-Pacific markets including China, Japan, and South Korea. In March 2026, Oldelft was acquired by Germany-based steute Technologies, a Battery Ventures portfolio company, from prior owner Smile Invest, becoming part of steute's Meditec segment. The company holds ISO 13485:2016 certification and operates a formal partnership services channel for collaborative 4D transducer development in cardio, surgery, and urology.
