主权项

1. An implantable device comprising a self-expanding filament-wound tubular structure having a circumference, opposing proximal and distal ends, and a crossing pattern of at least one filament having a length,
wherein said filament includes a multiplicity of filament portions defined as portions of the length of the filament separated by consecutive apices along the length of the filament, said apices comprising bent portions of said filaments located only at the opposing proximal and distal ends of said tubular structure, wherein the crossing pattern is non-interlocking and includes multiple crossover points along a length of a filament portion, wherein the filament is wound only on top of previously wound filament and does not pass underneath previously wound filament such that the filament is not woven or braided, and wherein no filament portion extends around the entire circumference of the tubular structure.
