Neutral Hybrid Braid Structure for Rotation-Stable Medical Delivery

The patent applies preliminary anti-action by pre-configuring the braid pattern with alternating wire directions (first wires in first direction, second wires in second direction) that create counteracting forces before delivery. This preliminary configuration prevents unintentional rotation during delivery by having the braid structure itself generate opposing rotational forces that cancel each other out, thereby maintaining attachment stability without compromising device functionality.

The patent applies local quality by varying wire directions locally within different segments of the braid pattern rather than uniformly throughout. Specifically, first wires are arranged in a first direction while second wires are arranged in a second direction, creating localized directional properties that collectively achieve rotational neutrality. This approach manages manufacturing complexity by organizing the braiding process into distinct wire groups with specific directional assignments.
