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.
