Accentus Medical

What Accentus Medical does

Accentus Medical Ltd is a UK-based B2B medical device surface engineering company headquartered at Harwell Campus, Didcot, with roots in UKAEA nuclear research from the 1970s. The company develops and supplies proprietary biocompatible coating technologies — Acusure® thermal plasma spray coatings (titanium and hydroxyapatite), Agluna® silver ion antimicrobial surface treatment, and Acusure Ag® hydroxyapatite coating with incorporated antimicrobial silver — applied to orthopaedic and other implantable medical devices. Its technology addresses two core clinical problems: durable cementless fixation of implants to host bone and soft tissues, and reduction of post-operative implant-related infections through silver ion antimicrobial efficacy. Coatings are applied at the company's ISO 13485:2016 certified facility with purpose-built plasma spray booths, and customers reference FDA Masterfile MAF-1691 in their own regulatory submissions.

Accentus generates revenue through two streams: custom contract manufacturing and supply of coated implant components (hardware sales) to orthopaedic OEMs, and regulatory testing services including mechanical, fatigue, SEM, and XRD analytical studies performed under ISO 13485 procedures. The go-to-market is enterprise field sales targeting medical device manufacturers globally, supplemented by attendance at industry conferences such as AAOS. Customers include orthopaedic OEMs across hip, knee, extremity, and spine segments; 3Spine, Inc. is a publicly disclosed partner for the MOTUS lumbar spine device. The majority of products are supplied to international customers outside the UK, spanning Europe, the Americas, and Asia Pacific.

Following the 2025 acquisition by STS Group (backed by Batavorum Capital), Accentus continues to operate under its established name as part of a multi-sector surface engineering platform with operations in the UK, Netherlands, and USA. The company has accumulated an estimated 300,000+ patients treated with Acusure® coated implants and 2,000+ Agluna® coated custom devices since first clinical use in 2006. Leadership is headed by CEO Dr Philip Agg, with Brian Howlett as Non-Executive Chairman, David Marson as CFO, and James Shawcross as Director of Quality and R&D.

Revenue model

1. Custom Surface Coating Manufacturing & Supply: Accentus Medical supplies its proprietary Acusure® plasma spray coatings (titanium and hydroxyapatite), Agluna® silver ion antimicrobial surface treatment, and Acusure Ag® silver ion hydroxyapatite coating to orthopaedic device manufacturers. Coatings are applied to customer-specified implants during manufacturing. Revenue is generated through the supply of coated components, likely on a per-order or contract manufacturing basis.
2. Regulatory Testing Services: Accentus Medical provides medical device regulatory testing services to the orthopaedic manufacturing sector. Services include mechanical testing (static tension/compression/shear, strain-life fatigue testing), analytical studies (scanning electron microscopy, X-ray diffraction), and coating validation testing. Performed under ISO 13485 certified procedures meeting ISO, ASTM, and US FDA requirements.
