Closed cell stents excel

Closed cell stents provide greater plaque coverage of the carotid artery, thereby potentially reducing the risk of a delayed embolism relative to open cell stents, the company says. The study was presented in Paris at the 60th Annual Meeting of the Society for Vascular Surgery by Dr Joseph Hart, University of Rochester School of Medicine and Dentistry, Rochester, New York, who helped collect the data during his Marco Polo fellowship in Dendermonde, Belgium.

The study compares the clinical results of open versus closed cell carotid stents in 709 patients. At 30 days post procedure, symptomatic patients that received the closed cell stent showed a 4.1 times reduction of stroke, transient ischemic attacks (TIA, a major predictor of stroke) or death – compared to the open cell stent group. The Carotid WALLSTENT Monorail represented more than 70% of the closed cell stents used in this study. Closed cell stents, such as Boston Scientific’s Carotid WALLSTENT Monorail, have overlapping or fully connecting struts and cover 5 to 10 times more of the vascular wall as compared to open cell stents that have both connecting and non-connecting struts.
