About Sigt LLC
Sigt LLC is a for-profit limited liability company registered as a sole proprietorship to receive federal contract and grant awards. Sigt LLC has developed proprietary "High Frequency Dielectric Sensing" technology to monitor tissue properties and lesion formation during cardiac ablation procedures.
Through several grant awards from the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health, Sigt LLC has developed novel systems integrating its dielectric sensing technology into cardiac ablation catheters. These systems enable intraoperative monitoring of ablation procedure parameters, tissue characterization, confirmation of durable lesion formation, and detection of adverse events like micro-bubbles to improve safety and efficacy. Sigt LLC's largest award is a $1.65 million Phase II project grant under the NHLBI's Cardiovascular Diseases Research program to optimize and validate a clinical-grade "High Frequency Dielectric Sensing Lesion Assessment System" integrated into an 8.5Fr radio frequency ablation catheter. Previous Phase I awards funded prototyping and proof-of-concept testing of this system as well as a separate "Intraoperative Cardiac Pulsed Field Ablation Lesion Assessment System" applying the dielectric sensing technology to pulsed electric field ablation procedures for atrial fibrillation treatment.
