Patent ID: 10772638

Abstract:
An occluding device for occlusion of fluid flow through a lumen of a body vessel is manufactured by wedging fibers between adjacent coil windings of a primary coil so that the fibers extend generally radially across the primary coil body between the primary coil windings and outward therefrom. An elongated adhesive applicator is inserted into the primary coil lumen and subsequently proximally withdrawn while simultaneously depositing along the primary coil windings. The fibers and the adhesive are placed in overlapping locations so that the fibers extend through the adhesive. The fibers are thus blocked from slipping along their length relative to the coil body by the adhesive adhering to the fibers inside the primary coil lumen. The adhesive extends radially outward from the coil lumen no farther than the outer primary coil radius. The adhesive adheres to the fibers and may or may not adhere with the primary coil windings.
