The AVE Micro Stents™
AVE Micro Stent is a stent model, recently introduced in clinical cardiology practice in Europe and undergoing currently multicenter clinical trials in USA. Both Micro Stent I and II are formed from a continuous segment of stainless steel wire in the zigzag design, and both display eight axial struts connected by eight radiused crowns. As the basic unitary element of the Micro Stent is either 3.0 or 4.0 mm in length (I&II, respectively), these devices are premounted on AVE delivery balloons as stents of : 6.0, 8.0, 9.0, 12.0, 15.0, 18.0, 21.0, 30.0 and 39.0 mm in length. Advantages of AVE Micro Stents include limited amount of metal, excellent x-ray opacity, highly customizable length and superior trackability. The degree of recoil is similar to the J&JIS stents. Stent profile allows passage through 6 and 7F guiding catheters. High flexibility of the AVE Micro Stent expands the range of accessible vessel segments. The analysis of the use of AVE Micro Stents in 1132 patients demonstrates the low complications rate as well as an overall restenosis rate of 20.9%.
