Angled probe for coronary sinus cannulation improves control, precision, and efficiency of cardiac lead placement
Technology description
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.
Surgical failure rates for lead insertion via coronary sinus cannulation can be reduced using angled probe with tactile feedback
The coronary sinus is radiolucent and its precise location is variable. Current cannulation techniques rely on dye pulses and image guidance to help locate the coronary sinus, which may be problematic for volume-overloaded patients. In addition, precisely steering a flexible catheter is difficult at distances over 50 cm, for which steerable catheters are helpful, but leverage is often inadequate to reach far posterior or angulated coronary sinus locations. The optimized angle and stiffness of this technology allows for the flexibility to navigate cardiac vessels, but also the rigidity necessary to provide leverage for distant access. The cannula does not make use of an obturator but instead has calibration marks to allow the surgeon to exert fine control over the navitation of the cannula. Minimizing the failure rate of this procedure will reduce patient morbidity risks, reduce prolonged patient hospitalization, reduce total operating time, and improve effectiveness of the intervention.
