Single unitary piece braided woven construct endovascular catheter with asymmetric aggregate flexural strengths among flexural planes

A method for producing a catheter device as a unitary single piece tubular braided woven construct having four distinct spiral patterns extending in a longitudinal direction using a multi-carrier braiding system comprising:

• a support plate on which is mounted a plurality of horn gears collectively arranged radially in a circle defining a collective radial inner surface and a collective radial outer surface;
• wherein each horn gear of the plurality of horn gears is rotatable about a respective central horn gear axis and has associated therewith at least one bobbin carrier configured to receive a respective bobbin of a wound wire;
• and wherein the plurality of horn gears represent multiple horn gear polar pairs with each horn gear polar pair of the multiple horn gear polar pairs representing two horn gears disposed radially in the circle 180 degrees of one another defining a distinct corresponding flexural plane for each of the four distinct spiral patterns having a corresponding aggregate flexural strength based on the wires associated therewith;
• the method comprising the step of:
• creating the four distinct spiral patterns by establishing asymmetric aggregate flexural strengths among the flexural planes;
• each of the four distinct spiral patterns having a different aggregate flexural strength.
