Fibra obtenida por aposición para uso en el despliegue endoluminal de dispositivos expandibles en anatomías tortuosas

摘要

A catheter assembly includes an expandable device that is disposed at a distal end of a catheter and expandable toward a fully deployed outer dimension. A fiber extends from the catheter and is releasably coupled to a side wall of the expandable device near or at an end of the expandable device to maintain an inner curvature of the expandable device as the expandable device is deployed.
