A new idea for a safer approach to the supra-aortic trunks: the Piton™ catheter

Carotid artery disease is among the most common causes of stroke, and stroke is the third leading cause of death in industrialized countries. Thus the personal health and socioeconomic burden of carotid artery disease is significant. Carotid artery disease accounts for approximately 5-12% of new strokes in patients amenable to revascularization therapy. Atherosclerosis is the main reason for stroke and accounts for approximately one third of all cases. Carotid stenting is nowadays considered a valid standard alternative to surgical carotid endarterectomy, especially in patients having a high perioperative risk. The first carotid balloon angioplasty was carried out in 1979 and the first carotid balloon-expandable bare metal stents were implanted 10 years later, in 1989. However, carotid stenting at that time was associated with major complications, due to extrinsic compression and subsequent to the steel stents used. The Piton™ GC (carotid guide catheter) is intended to facilitate the introduction and placement of interventional devices (e.g., guidewires, stent delivery systems, dilation balloons, angiographic- or micro-catheters, etc.) into the human vasculature to treat vascular obstructive disease, including but not limited to the supra-aortic vessels.
