Average percentage of cell types within central, mid, and outer regions of vessel cross sections treated with IMPEDE, AVP, and Nester devices. Note: The vessel implanted with AVP at 60 days was not scored due to the presence of extensive intradevice vascular channels. Additionally, multinucleated giant cells were assessed qualitatively and are not reflected in this figure; however, they are reflected in the healing score assigned (defined in Table 2).
