(CORRECTED: See below.)

Seattle-based NeuroVista, a developer of devices for the treatment of epilepsy, raised $33.8 million in a second-round funding and left behind its former name, BioNeuronics.

The company, founded in 2002 by whiz kid Daniel DiLorenzo, has been quiet about its technology and commercial direction. In April, however, DiLorenzo received a patent for a “neurological control system” using “closed-loop intracranial stimulation” for the “optimal control of neurological disease.” In other words, given NeuroVista’s public interest in epilepsy, it sounds very much like it’s working on implantable neuromodulation devices that could monitor and perhaps counteract the early signs of an oncoming seizure. (Hat tips: VentureWire and Neurotech Business Report).

VentureWire also reports that one other venture-backed company, NeuroPace, and two established device makers, Medtronic and Houston-based Cyberonics, may also be researching epilepsy devices.

Here’s NeuroVista’s vaguely worded announcement. The round was led by Advanced Technology Partners and Delphi Ventures, who were joined by Three Arch Partners, Sprout Group and Foundation Medical Partners.

CORRECTION: An earlier version of this item stated that Dan DiLorenzo “co-founded” NeuroVista. He’s informed us that he was the sole founder, and I’ve corrected the item to reflect that.
