Covidien launches microwave ablation system worldwide
Covidien has released the Evident microwave ablation system globally for use in soft tissue.

The Evident microwave ablation system is intended for coagulation of soft tissue during percutaneous, laparoscopic and open surgical procedures. Microwave energy emanates from the feed point of the radiating section of the antenna, causing coagulation of the tissue. The system then creates heat by generating friction through the vibration of water molecules. With microwave ablation, there is no current flow through the patient, eliminating the need for grounding pads, according to the Hamilton, Bermuda-based company.

Microwave technology has shown promising results in ablating soft tissue in patients who are not candidates for surgical resection and have few remaining treatment options, Covidien said.
