Figure 1.

Multi-panel figure illustrating scaffold structure and in vivo imaging. Panel A shows a schematic cross-section of the resorbable fibrillated scaffold, with magnified views highlighting its architecture under scanning electron microscopic visualisation. Panel B presents a longitudinal cross-sectional optical coherence tomography (OCT) image of a vessel, with scaffolded and non-scaffolded regions labeled. Panel C displays axial OCT images at different time points: native vessel before implantation, immediately post-implantation, and at one- to three-month follow-up.

Serial intravascular OCT of the resorbable fibrillated scaffold. (A) 3D rendering of the scaffold's tubular, strut-free design with scanning electron microscopy insets of the cross-section (left) and outer surface (right). (B) Post-implantation longitudinal OCT view; dashed bracket marks the scaffolded segment. Green and red arrows indicate sites of the cross-sections in (C), which shows axial OCT images at post-implantation (green, red), 1-month (yellow), and 3-month (blue), with magnified insets highlighting scaffold-vessel interaction over time. Scale bar: 1 mm. Compared with the native vessel (green), reduced backscatter clearly delineates the device margins (red), producing a characteristic “blurring” that diminishes with time.
