Abstract
This is a braided tubular structure made up of a plurality of interwoven fibrous members, preferably ribbons, a majority of which comprise one or more superelastic and (at least) ternary alloys of nickel, titanium, and at least about 1.5% (wt) of one or more alloying members selected from the group consisting of vanadium, chromium, manganese, iron, and cobalt.
Claims16
A tubular structure comprising a plurality of constituent filaments:
- wherein said plurality of constituent filaments are interwoven into a braid forming an inner passageway,
- wherein at least some of said constituent filaments are superelastic alloy constituent filaments,
- wherein said superelastic alloy constituent filaments have a cross section with a maximum dimension no greater than about 12.0 mils, and
- wherein said superelastic alloy comprises a nickel titanium alloy containing at least about 1.5%(wt) of at least one alloying element selected from the group consisting of vanadium, chromium, manganese, iron, and cobalt.
