Sofinnova Partners Announces Two First Investments from its MD Start III Medtech Acceleration Fund

Sofinnova Partners announced the second investment from its MD Start III Fund, a medtech accelerator that actively works with clinicians and entrepreneurs to develop disruptive medical devices. In May 2019, the fund raised €48 million from key institutional investors and has made two seed investments so far: MastOR and Gradient Denervation Technologies. The most recent investment is in MastOR, a French company leveraging its core expertise in surgical robotics to develop enhanced laparoscopic devices to improve the precision and ergonomics of minimally-invasive surgery. The company was founded in 2019 by a renowned pioneer in laparoscopic surgery, Professor Brice Gayet of the Paris-based Institut Mutualiste Montsouris, and entrepreneur, Pierre Campredon.

“The Sofinnova MD Start team is known for its active, hands-on approach to company building,” said Prof. Gayet. “Their strategic and operational expertise is the perfect complement to the years of research and prototyping we have conducted thus far. Together, we will be able to accelerate the development of this game-changing technology and bring it to its full potential.”

MD Start III also invested in Gradient Denervation Technologies in February. The company is developing a medical device for a transvascular treatment of pulmonary hypertension, based on prior research and intellectual property developed at Stanford University. This has been an important area for MD Start, given its focus on interventional cardiology as a very innovation-savvy and fast-adopting medical community.

“These investments exemplify our mission of transforming innovative ideas into medical realities and backing inventors who are developing disruptive concepts for outstanding medical devices and procedures,” said Anne Osdoit, Partner at Sofinnova Partners. “Our network and partnerships have yielded a rich deal flow pipeline and we are confident in the potential for this fund to continue uncovering first-class devices that address major unmet medical needs.”
