Aliso Viejo-based Cianna Medical Inc. has raised $4 million, according to a U.S. Securities and Exchange Commission filing.

Cianna develops devices to treat early stage breast cancer in women. The company was founded in 2007 and has raised, including this new funding, about $45 million in several venture rounds since February 2008, according to a report.

Its most recent deal prior to this one was $10 million in financing from GE Capital Health Finance Services in May 2014.

The company did not disclose the names of the investors or what the proceeds are for.

Investors in a previous round included La Jolla-based Windamere Venture Partners, San Rafael-based Fog City Fund and Bedford, Mass.-based BioLucent, the report said.
