Tryton Medical raised $4 million in a new round of equity financing, according to an SEC filing posted this week.
The Durham, N.C.-based vascular device developer has not yet stated how it plans to spend funds raised or the closing date for the round.
Money in the round came from 8 unnamed sources, according to the SEC filing, and the company is looking for an additional $4 million before closing the round.
In October 2015, Tryton Medical said that data from a post hoc analysis of a randomized clinical trial of its Tryton side branch stent for patients with coronary bifurcation lesions showed reductions in target vessel failure and improved side branch diameter.
Results from the study were published in the journal Catheterization and Cardiovascular Interventions.
The 289-patient post-hoc analysis focused on patients with side branch bifurcation lesions 2.25 mm in diameter or greater.
