DEFINITION

Classification: 604/526

Lumen enforced by embedded or coiling strands:

(under subclass 524) Subject matter providing filaments either dispersed throughout the internal structure of the conduit, enclosing the lumen or encircling it.

(1) Note. For placement in this subclass the strand should provide strength in the axial direction to prevent the lumen from collapsing.
