Sigma-Tec

Sigma-Tec is a medical technology company specializing in the development and commercialization of advanced radiofrequency (RF) ablation systems for the treatment of solid tumors. The company's flagship technology utilizes a unique electrode design and power delivery algorithm to create precise, predictable zones of thermal necrosis in cancerous tissue while sparing adjacent healthy structures. Sigma-Tec's solutions are primarily targeted at difficult-to-treat cancers, including those in the liver, pancreas, and lungs, where surgical resection may not be feasible. By providing a minimally invasive alternative to traditional surgery, the company aims to improve patient outcomes and reduce recovery times in oncology care. Sigma-Tec continues to expand its clinical evidence base and geographic reach through partnerships with leading cancer centers worldwide.
