Claim of US Patent No. 10,363,020

1. A method of use of a composite arteriotomy plug comprising:positioning a composite arteriotomy plug having an elongate core member, a distal end, and a proximal end within a tissue tract adjacent to a vessel puncture,
wherein the composite arteriotomy plug varies along an axial extent of the composite arteriotomy with regard to at least one of composition, placement, and thickness of one or more layers disposed about the elongate core member of the composite arteriotomy plug as a function of longitudinal distance from the distal end of the composite arteriotomy plug;
controlling longitudinal exposure of the composite arteriotomy plug to body fluids within the tissue tract by altering at least one of the composition, placement, and thickness of the one or more layers disposed about the elongate core member of the composite arteriotomy plug as a function of longitudinal distance from the distal end of the composite arteriotomy plug; and
allowing the composite arteriotomy plug to expand radially upon contact with bodily fluids with a swelling profile in which swelling is generally initiated at or near the distal end of the composite arteriotomy plug and continues at more proximal locations as a function of time.
