Onocor LLC

Onocor LLC develops the ŌNŌ transcatheter retrieval system, a specialized device designed for percutaneous removal of embolized, misplaced, or malfunctioning left atrial appendage (LAA) occlusion devices and other structural heart implants. The system addresses a critical clinical need in interventional cardiology and electrophysiology, where device complications from catheter-based structural heart procedures require retrieval without resorting to surgical explantation. The ŌNŌ system operates on a four-step mechanism: receive, align, compress, and remove, enabling physicians to safely retrieve devices from complex anatomical positions, including retrieval from the left ventricular outflow tract. This technology reduces procedural morbidity by eliminating the need for remedial open-heart surgery and serves as a safety net that encourages adoption of less-invasive structural heart interventions. The company is positioned in the interventional cardiology and electrophysiology markets, supporting the growing field of catheter-based structural heart disease management. Clinical validation includes peer-reviewed publication in the Journal of the American College of Cardiology (JACC), documenting first-in-human percutaneous device retrieval cases.
