Histological samples from animal 4 show good apposition of the p48 MW HPC with the arterial wall (a) with the braided wires of the device (b, white arrow) covered by a thin neointimal layer (b, black arrowheads). The p48 MW has a similar appearance within the vessel (c) as well as at higher power magnification (d) with a thin neointimal layer seen (d, black arrowheads)
