An intravascular stent is a synthetic tubular structure intended for permanent implant in native or graft vasculature. The stent is designed to provide mechanical radial support after deployment; this support is meant to enhance vessel patency over the life of the device.
Intravascular stent for preventing occlusion of branch vessels and method for manufacturing the same
This invention discloses an endovascular stent for preventing branch vessel occlusion. The stent includes a proximal end, a distal end, and a mid-section. The stent is a mesh-like structure formed by weaving multiple biocompatible braided filaments with one or more high-density metal wires. The number of filaments in the proximal and distal ends is less than that in the mid-section, and the mesh size in the proximal and distal ends is larger than that in the mid-section. This endovascular stent provides sufficient support while effectively reducing the risk of branch vessel occlusion. The stent is also easier to press into a smaller diameter stent delivery tube, and the filaments at both ends are less prone to tangling during stent deployment.
