Dynamic Scoring®

flex’s Dynamic Scoring® allows for long linear scores to be made along the entire length of the diseased vessel at very low atmospheric pressures. FLEX exerts less than 1atm of force on the arterial wall. 

Static scoring utilizes balloon apposition to force the scoring elements into the artery wall at much higher pressures while having to inflate multiple times in long diseased segments.

Vessel Preparation

Because the treatment and procedures necessary to adequately prepare vessels for adjunctive therapy are often complex and challenging, VentureMed created the FLEX Scoring Catheter®. VMG’s innovative FLEX catheter is an easy-to-use and cost-effective “vessel preparation” device. FLEX incorporates a proprietary technology that allows for effective dynamic linear scoring with a lower propensity for vessel wall damage or barotrauma. The unique design allows the operator to easily prepare a diseased vessel in a single insertion without the need for multiple balloon inflations. FLEX is an ideal device to use prior to adjunctive therapies (angioplasty, drug coated balloon, bare metal stenting and drug eluding stent). 

By incorporating Dynamic Scoring®, FLEX offers an effective and safe alternative to balloon-based scoring technology. Without the need for multiple balloon inflations, the operator can effectively treat a much wider range of vessel lengths and diameters in a single catheter — not only saving time, but cost as well.
