OrthoSensor, a US-based medical sensor technology provider backed by healthcare providers Bridger Healthcare and Dignity Health, has been bought by medical technology producer Stryker for an undisclosed amount.
Founded in 2007, OrthoSensor provides sensor-assisted orthopaedic devices used by surgeons to assist with musculoskeletal care.
Ziegler Meditech Equity Partners (ZMEP), a joint venture between investment bank Ziegler and healthcare consultancy Meditech Advisors, joined unnamed angel investors to provide $6m of series A funding for the company in 2008.
OrthoSensor raised $21m in series B funding from ZMEP and an undisclosed strategic investor in 2011 before collecting an additional $15m from undisclosed investors the following year.
The company received $13m in a 2013 series B-2 round backed by Dignity Health and ZMEP alongside unnamed strategic and private investors.
In 2015, OrthoSensor pulled in $19m through a series C round featuring Bridger Healthcare and the Tullis Health Investors-managed Tullis Growth Fund, adding $2.3m from undisclosed investors in 2016 and $2.7m in 2018, according to regulatory filings.
