Strong Flat Stent Membrane with Low Blood Permeability

Covered stents are widely used in diseases such as aortic dissection and aneurysm. They are highly effective due to their excellent properties in the areas of release resistance, strength and blood permeability. Flat stent membrane, known as 404070,404085, 402055 and 303070,is the core materials for the covered stents. This membrane has been developed to have a smooth surface and low water permeability, making it an ideal polymer material for the design of medical devices and manufacturing technology. The stent membranes are available in a range of shapes and sizes to fulfill the special needs of different patients. Furthermore, AccuPath^® offers a range of customized membrane thickness and sizes to meet your requirements.
