Biotech firm ViOptix just tacked $4.4 million onto an already $12.2 million fourth round of funding and landed $3 million in debt financing to break even, reports VentureWire. The Fremont, Calif. company says this will be its last round of venture capital.
Around since 1999, ViOptix has pioneered a device that allows doctors to detect how much oxygen exists in human tissues through a non-invasive procedure. No plans for the new money, beyond self-sufficiency, have been disclosed. All told, the company has brought in about $33 million to date.
Investors include Canadian Medical Discoveries Fund, Channel Medical Partners, Morningside Technology Ventures, MDS Capital and Trident Capital.
