Abstract

A vascular prosthesis utilizing drawn-filled tubing (DFT) wire to aid in visualizing the prosthesis without needing supplemental radiopaque material is described.

Description

[0001] related application [0002] This application is a non-provisional application of, and claims priority to, U.S. Provisional Application Serial No. 62 / 768,803, filed November 16, 2018, entitled "Stent," the entire contents of which are hereby Incorporated herein by reference. Background technique [0003] Vascular prostheses (artificial blood vessels) such as stents and stent-grafts are used in the vascular system for various reasons. A non-exhaustive list includes supporting the opening of diseased or occluded blood vessels to facilitate blood flow, blood flow diversion involving diversion of blood flow away from a target area such as an aneurysm, and maintaining materials (e.g., embolic materials) within the treatment site To activate local blockages in the area. [0004] Visualization is important for vascular prostheses so the surgeon can confirm proper placement of the device in the vasculature. Traditional metal stents utilize a good shape memory material such a...
