Abstract
A braided device comprising: filaments of a first type and of a second type, the second type differing from the first type in at least one characteristic; the first type of filaments defining an integral symmetrical 1×1 sub-pattern; and the combination of the first type of filaments and the second type of filaments being braided together into a braided device exhibiting a uniform braid pattern.
Claims16
A braided device comprising:
- a plurality (M) of filaments of a first type and a plurality (N) of filaments of a second type;
- said filaments of the first type being substantially more rigid than the filaments of the second type;
- the plurality (M) of filaments of the first type in said braided device being an even integer;
- the ratio N/M being an odd integer;
- said first type of filaments defining an integral axis symmetrical 1×1 sub-pattern producing a relatively stable axis symmetrical structure independent of the filaments of the second type and providing at least 75% of the rigidity of the braided device;
- wherein the combination of said first type of filaments and said second type of filaments are braided together into a braided device exhibiting a uniform braid pattern.

A method for braiding comprising:
- selecting a braiding apparatus having a number of horn gears, the number of horn gears being designated N;
- selecting a first filament type and a second filament type, said filaments of the first type being substantially more rigid than the filaments of the second type;
- and
- loading said first filament type on carriers on said horn gears, such that the number of horn gears being loaded, designated M, satisfy the equation N/M=odd integer, and M is an even integer, said horn gears being loaded symmetrically and evenly;
- loading said second filament type on all unoccupied carriers on said horn gears;
- and
- operating said braiding apparatus to produce a braided device having a braid pattern,
- whereby said first filament type defines an integral axis symmetrical 1×1 sub-pattern producing a relatively stable axis symmetrical structure independent of the filaments of the second type and providing at least 75% of the rigidity of the braided device.
