PEAK Surgical Announces Positive Results From Preclinical Study of PEAK PlasmaBlade(TM) for Obstetric and Gynecologic Surgery
Date:5/6/2008

ontrolling bleeding and minimizing thermal damage, the PEAK PlasmaBlade has the potential to be an important dissection tool for surgical procedures," said John Tighe, president and chief executive officer of PEAK Surgical. "PEAK Surgical is committed to bringing this highly precise tissue dissection technology to market as quickly as possible."

About PEAK's Technology

For decades, surgeons have relied on scalpels to cut skin and delicate tissues and used electrosurgical devices to cut and coagulate fat and other thicker, tougher tissues. Although scalpels precisely cut tissue, they do not control bleeding. Electrosurgical devices, on the other hand, cut efficiently and control bleeding but can cause extensive thermal damage to surrounding tissue. In cases where the risk of collateral damage or scarring from electrosurgery is considered to be unacceptable, surgeons must use both a traditional scalpel for cutting and an electrosurgery device for coagulation. The PEAK PlasmaBlade combines into a single surgical tool the precision of a scalpel and the bleeding control of a traditional electrosurgery device.

In addition, unlike most radiofrequency-based surgical products that use continuous voltage waveforms to cut tissue, the PULSAR Generator supplies pulsed plasma-mediated electrical discharges through the PEAK PlasmaBlade. These pulsed plasma-mediated discharges and electrode insulation techniques were originally developed at the Hansen Experimental Physics Laboratory and Department of Ophthalmology at Stanford University. Because the radiofrequency is provided in short on-and-off pulses and the blade is insulated, the PlasmaBlade cuts tissue at an average temperature that is half that of a conventional electrosurgery device and can be as low as 50 degrees Centigrade. This temperature reduction results in reduced heat transfer and half the damage to surrounding tissues compared with traditional electrosurgical devices. The PEAK PlasmaBlade also c
