Clinical Experience With a Novel Perfusion Balloon Catheter in Patients With Coronary Artery Perforation: Primary Results From the Ringer Clinical Study.

ABSTRACT:

Background

The Ringer perfusion catheter (Teleflex) features a novel design with a spiral-shaped inflatable balloon that approximates a hollow cylinder when inflated to manage hemorrhage associated with coronary artery perforation (CAP) during percutaneous coronary intervention while enabling distal perfusion.

Methods

In a multicenter, prospective, single-arm study, the safety and efficacy of using the Ringer device in the treatment of CAP were assessed. The primary efficacy end point included successful Ringer delivery across the perforation site, angiographic confirmation of no extravasation with balloon inflation, and demonstration of antegrade coronary flow. The primary safety end point was freedom from device-related thrombosis and coronary dissection. Clinical and angi
