Optimal Tissue Debulking Protocol Defined For Treating In-Stent Restenosis (ISR) With Boston Scientific Corporation’s JETSTREAM Navitus Atherectomy Device

LEXINGTON, Mass.--(BUSINESS WIRE)--CBSET, a not-for-profit preclinical research institute dedicated to biomedical research, education, and advancement of medical technologies, announced today that its scientists have defined the optimal tissue debulking protocol for treating in-stent restenosis (ISR) with Boston Scientific’s JETSTREAM® Navitus atherectomy device. These findings were disclosed this week at the “CRT 2015” annual scientific meeting in Washington, D.C., Feb. 21-24.

The study (“Optimal Number of Runs Using the JETSTREAM Navitus Device to Achieve Maximum Tissue Debulking of In-Stent Restenosis in a Porcine Stent/Balloon Injury Overstretch Model”) determined that the Boston Scientific JETSTREAM Navitus atherectomy device achieved optimal tissue debulking after two blade-up (BU) runs, with no further gain in debulking after the second run. This study also confirmed that stent damage was minimal after the procedure, with no disruption to stent struts or stent integrity. Prior to this study, the number of runs needed to achieve optimal tissue debulking in ISR using the JETSTREAM Navitus device was unknown.
