Sunnyvale, Calif. -- IntraOp Medical, a Sunnyvale-based developer of technology for the treatment of cancer, said on Friday that it has raised $5.4 million in a new round of private equity funding as part of a capital restructuring that also includes the extinguishment of more than $8.7 million worth of notes and payables. The company also has named wireless industry veteran John Powers as its new president and CEO. Powers, who previously held executive posts at metroPCS, VelociTel, Inc., Crown Castle International and Motorola, takes over for Donald Goer, who has become the company's chief scientist. "The new capital and debt restructuring will provide IntraOp with the resources it needs to accelerate its growth strategy," said Goer. IntraOp's flagship product is a portable electron-beam linear accelerator designed for use in operating rooms. The system allows oncologists to pinpoint areas that requires radiation and immediately deliver high doses directly to the affected tissue during cancer surgery.
