NeoChord has raised $20.6 million in a new round of equity financing, according to a recently posted SEC filing.

The St. Louis Park, Minn.-based company offered Series D preferred stock in the round, with the first sale noted on October 31, according to the filing.

A total of 27 anonymous investors have joined in the offering, according to the filing. NeoChord is looking for an additional $8.8 million before closing the round, bringing the total raised up to a hoped for $29.4 million.

The company has not yet stated how it plans to spend funds in the round.

Earlier this month, NeoChord said that it closed a $25 million Series D equity financing round to help support its mitral valve repair system intended to treat mitral valve regurgitation.
