St Jude Medical, a US-based healthcare technology provider, has led a $10m investment round in iRhythm Technologies and will market its heart monitor to customers.
This deal marks St Jude’s first public move into iRhythm.
The other investors in what is effectively iRhythm’s B round include return venture capitalists Mohr Davidow Ventures and Synergy Life Science Partners.
The two VCs, alongside Stanford University and UNC Kenan-Flagler Private Equity Fund, backed last year’s $6.5m series A extension that was added to the initial $12.5m raised in 2007, according to news provider VentureWire.
