a-b, Illustration (a) and photo (b) showing clinical catheter access via the established femoral arterial sheath for smart stent delivery. Scale bar, 12 mm. c, Delivery catheter navigation over glide wire. Real-time fluoroscopy is used to visualize the progression and position of the glide wire and catheter. Once the glide wire is successfully navigated to the desired location, it serves as a track along which the clinical catheter loaded with the smart stent can be advanced. Scale bar, 4 mm. d-e, Diagnostic angiograms evaluating a side branch jailed by the smart stent. (d) Post-implantation and (e) pre-implantation angiograms demonstrate that the smart stent does not obstruct flow to the side branch. Preserving anterograde blood flow in jailed branches is important for the utilization of the smart stent in a variety of vascular locations. The smart stent’s mesh structure is specially designed to prevent the complete obstruction of flow across the smart stent to the side branches. Scale bars, 3 mm. f-g, Versatile deployment of the smart stent in multiple locations. Notably, the appearance of the smart stent in the image (g) is lighter (fainter) in color compared to image (f). This variation in visualization is attributed to differences in tissue thickness and the distinct anatomical areas being imaged. Scale bars, 6 mm. Panel a has been partially created in BioRender.
