Anchoring and migration of balloon in REBOA

A mechanical theory is described for a phenomenon in the surgical procedure of resuscitative endovascular balloon occlusion aorta (REBOA). In this pushed into by catheter and then inflated order to stop haemorrhage. One hazards tendency migrate away from its intended position. This work examines mechanics anchoring migration analysing effects pressure waves, sheet flow solid friction thin gap between walls balloon. viscoelastic model adopted wall waves left ventricle The lubrication approximation used blood aorta. Samples quantitative predictions are discussed on how inflation characteristics affect migration. crucial roles placement pointed out, which should help guiding manufacturing balloons their usage field.
