Thermedical, a Waltham medical equipment company, has received Food & Drug Administration clearance to market its technology for the coagulation and ablation of soft tissue during certain surgical procedures.

FDA clearance “is a significant milestone for Thermedical as it will facilitate our plans to carry out a series of clinical trials to evaluate the efficacy of our system for treating large, solid tumors, including liver cancer,” president Michael G. Curley said Wednesday in a statement.

Thermedical said that substantial preclinical testing of its ablation system was carried out under multiple grants from the National Institutes of Health. Thermedical was also awarded $500,000 by the Massachusetts Life Sciences Center.

Privately held Thermedical was founded by Curley and Patrick S. Hamilton, two alumni of the Hyperthermia Center at the Massachusetts Institute of Technology.
