Tangent Medical Technologies, a University of Michigan startup based in Scio Township, has secured $4.5 million in venture capital to accelerate the commercialization of its medical device.

Ann Arbor-based Arboretum Ventures, Cambridge, Mass.-based Flagship Ventures, Pennsylvania-based Osage Ventures and several private individuals invested in Tangent, which has a small operation on Parkland Plaza south of Jackson Road.

The financing comes a few months after the company hired Ann Arbor entrepreneur Jeff Williams to serve as its chairman and CEO. Williams previously served as CEO of Pittsfield Township-based HandyLab and Scio Township-based Accuri Cytometers, which was also funded by Arboretum and Flagship.

Williams, who is also serving as CEO of Ann Arbor-based U-M startup Life Magnetics, said in a statement that the new funding would help Tangent Medical complete regulatory filings and get its product onto the market.

Tangent has developed an proprietary device called NovaCath, which would replace traditional intravenous (IV) drug delivery systems in hospitals.

The company was the first startup to spin out of U-M's Medical Innovation Center, which allows multidisciplinary post-doctoral researchers to collaborate to develop new technologies that can be commercialized.

Founders Adrienne Harris, Elyse Kemmerer and Steven White will stay with the company.

Arboretum Ventures managing partner Tim Petersen and Flagship Ventures partner Harry Wilcox will join Tangent Medical's board as a result of the investment.

So great to see such beneficial technology becoming so successful in finding funding... I was curious about the UM connection, so did a little digging, thought others might be curious too. From I see that Adrienne Harris got BSE and MSE degrees in biomedical engineering from UM , Steven White got his BSE, MSE and PhD in Mechanical Engineering from UM, Elise Kemmerer got her PhD in Neuroscience from UM. Great to see that they chose to stay IN MICHIGAN to start their company, kudos and thanks. (Oh, also minor typo "developed an proprietary device" , "an" should be "a" - there seem to be fewer and fewer typos on, yey....)
