March 28, 2025- Teleflex Incorporated announced that the preliminary results from its Ringer™ PBC IDE study were reported in a featured presentation at the CTO Plus Conference in New York by the study’s principal investigator. Ringer™ PBC is a rapid-exchange percutaneous transluminal coronary angioplasty (PTCA) catheter with a unique helical balloon. When inflated, the balloon approximates a hollow cylinder with a large central perfusion lumen, allowing for continuous coronary blood flow during prolonged inflations.
The study enrolled 30 participants, and analysis was performed based upon intention-to-treat. Ringer™ PBC is currently indicated for balloon dilatation of coronary artery or coronary bypass graft stenoses where the physician desires distal blood perfusion during balloon inflation for the purpose of improving myocardial perfusion.
