Background: Poor durability of femoropopliteal artery (FPA) stenting is multifactorial, and severe FPA deformations occurring with limb flexion are likely involved. Different stent designs result in dissimilar stent–artery interactions, but the degree these effects insufficiently understood. Objectives: To determine how different affect flexion-induced deformations. Methods: Retrievable markers were deployed into n = 28 FPAs lightly embalmed human cadavers. Bodies perfused CT images acquired...
High failure rates of femoropopliteal artery (FPA) interventions are often attributed to severe mechanical deformations that occur with limb movement. Torsion the FPA likely plays a significant role, but is poorly characterized and associated intramural stresses currently unknown. torsion in walking, sitting gardening postures was n = 28 situ FPAs using intra-arterial markers. Principal strains were quantified superficial femoral (SFA), adductor hiatus segment (AH) popliteal (PA) analytical...
High failure rates of femoropopliteal artery (FPA) interventions are often attributed to severe mechanical deformations that occur with limb flexion. One these deformations, cross-sectional pinching, has a direct effect on blood flow, but is poorly characterized. Intra-arterial markers were deployed into n = 50 in situ cadaveric FPAs (80 ± 12 years old, 14F/11M), and limbs imaged standing, walking, sitting gardening postures. Image analysis was used measure marker openings calculate FPA...
Abstract The dual nano–macro nature of continuous nanofibers holds great promise in bridging the unique nanoscale properties DNA to macroscopic devices. However, due limitations existing manufacturing methods, controlled fabrication macroscopically long has not been achieved so far. This article presents optimized electrospinning substrate‐free and uniform with lengths diameters ranging from ultrafine (<50 nm) submicron scale. Mechanical tests individual show highly nonlinear deformation...
Noncompressible hemorrhage is a leading cause of preventable death in civilian and military trauma populations. Resuscitative endovascular balloon occlusion the aorta (REBOA) promising method for controlling noncompressible hemorrhage, but safe inflation parameters are not well defined. Our goal was to determine associated with benchtop flow aortic/balloon rupture ex vivo human aortas test hypothesis that optimal characteristics depend on systolic pressure subject demographics.Aortic...
