Angled probe for coronary sinus cannulation improves control, precision, and efficiency of cardiac lead placement

Summary

Cardiac resynchronization therapy has emerged as the standard of care to reverse cardiac dysynchrony in patients with advanced congestive heart failure. This therapy is administered by inserting endocardial leads directly into the heart via coronary sinus cannulation. However lead insertion is technically challenging and standard cannulation devices are long and flexible, resulting in limited control by the surgeon. This technology is a right-angled cannula probe with a rigid frame that facilitates proper entry into the coronary sinus and allows monitoring of tissue interactions via tactile response. This device can improve the effectiveness of direct coronary sinus cannulation by improving ease of insertion, reducing total operating time, and reducing patient morbidity risks.

Technology Benefits

Improves steering and monitoring of catheter positionAbility to catheterize at distances greater than 50cm without losing leverageEase of insertionReduces pain and morbidityReduces cost, procedure time, and training with improved controlCustomizable contour geometry and distance markings specific to individual patient anatomyApplicable to a wide variety of other cardiac intervention proceduresPatent Information:Patent Pending (US 20160220811)Tech Ventures Reference: IR CU14007, IR CU14193

Technology Application

Cardiac lead placement during coronary resynchronization therapyInsertion of cardiac instrumentationInsertion of monitoring instruments (e.g. temperature, pressure, oxygen saturation) in the coronary sinusInsertion of prostheses, including rings, sutures, stiffeners, and pumps to reduce heart failureDelivery of contrast agents for angiographyCan be adapted for use in other procedures involving coronary sinus, intrapericardial access, intracardiac access (valve repair), transseptal puncture, and to all pacemakers/ICDs
