Multi-strand implant with enhanced radiopacity
View Patent ↗An implant for medical use, and methods of making same, having a body formed of a plurality of single strands of a first material. The body further includes at least one multi-strand of radiopaque material incorporated among the single strands, the multi-strand having at least two side-by-side filaments of radiopaque material that lie substantially contiguous to each other over substantially the entire length of the multi-strand.
1. An implant for medical use, comprising:
a structure having a body constructed to include;
a plurality of only single strands composed of at least a first non-radiopaque material and having at least one multi-strand of radiopaque material incorporated among the single strands, the multi-strand having at least two side-by-side filaments of radiopaque material that lie substantially contiguous to each other over substantially the entire length of the multi-strand, a diameter of each side-by-side filament is the same as a diameter of each of the single strands.
2. The implant of claim 1 wherein each of the side-by-side filaments of the multi-strand is a monofilament of radiopaque material.
3. An implant for medical use, comprising:
a structure having a body wall formed of a plurality of only single strands composed of at least a first non-radiopaque material, the single strands composed of at least a first non-radiopaque material establishing a first spacing pattern and a first wall thickness, the body wall including a plurality of multi-strands of radiopaque material interspersed with the single strands, each multi-strand having at least two side-by-side filaments of radiopaque material that lie substantially contiguous to each other, and each multi-strand joining in the first spacing pattern without substantial deviation from that pattern and without substantially altering the first wall thickness, a diameter of each side-by-side filament is the same as a diameter of each of the single strands.
4. The implant of claim 3 wherein each of the side-by-side filaments of the multi-strands is a monofilament of radiopaque material.
5. The implant of claim 3 wherein the first spacing pattern is one of an open braid pattern and an open weave pattern.
