Saphena Medical raising Series B round for its endoscopic vein harvesting device

Boston startup Saphena Medical is kicking off a Series B round for its endoscopic vein harvesting device.

The startup launched last year with $3 million in Series A funding, which it said at the time was enough to push through regulatory clearance. But it’s recently raised another $1.2 million of a potential $3 million Series B round, according to a recent regulatory filing.

Saphena Medical spun out of Pavilion Medical Innovations, a sort of medical device think tank formed out of  Catalyst Health Ventures.

The startups working to consolidate veinous harvesting devices into one tool – the so-called Venapax Endoscopic Vessel Harvesting System. It holds a flexible tip that stays closed during dissection, but it expands when the electrodes used in surgery are deployed. It says:

The electrodes can be easily deployed or retracted as needed during dissection. Precise control is delivered via bi-directional, circumferential rotation of electrodes. This allows for easy access to all vessel side branches because the device can be easily positioned for all orientations.  Bi-polar cauterization treats tissue placed between electrodes on either side where the double-sided blade cuts tissue after cauterization.

The company’s led by Pavilion founder Michael Glennon, who is also CEO of Cruzar Medsystems, another Boston device startup that’s developing a balloon catheter meant to cross obstructive lesions.
