Braid-reinforced catheter shafts: How to ensure X-ray and MRI compatibility

May 25, 2018 By Heather Thompson

To achieve stiffness in intervascular catheter shafts, manufacturers often turn to stainless or nitinol – but those materials aren’t suited for MRI. Luckily, low-cost fibers offer a viable alternative. William Li and Steve Maxson, Adam Spence Intervascular catheter shafts are designed to be relatively stiff at the proximal end, to facilitate the … [Read more...] about Braid-reinforced catheter shafts: How to ensure X-ray and MRI compatibility
