PEAK Surgical

PEAK Surgical, Inc. was a Palo Alto, California-based medical device company that developed the PEAK Surgery System, a proprietary tissue dissection platform built on pulsed plasma radiofrequency technology originally invented at Stanford University's Hansen Experimental Physics Laboratory. The system comprised the PEAK PlasmaBlade — a family of disposable cutting devices offering the precision of a scalpel and the bleeding control of traditional electrosurgery without the extensive collateral thermal damage — and the PULSAR Generator. The PlasmaBlade operated at temperatures as low as 50 degrees Celsius, roughly half that of conventional electrosurgical devices, resulting in significantly reduced tissue damage, scarring, and inflammation. PEAK Surgical was acquired by Medtronic in 2011, and the PlasmaBlade product line continues under the Medtronic brand.
