Soft tissues' expanders: computer-assisted simulation of elasticmesh deformation and fractal vascular geometries in controlled skinexpansion

摘要

Using vascular fractal geometries, the coupling between elasticnetwork deformation and vascular branching pattern modification undersimulated controlled skin expansion is described. The simulation modelis based on two fundamental biological considerations: the organizationof the elastic network in meshes of pre-established geometricconfiguration and the branching distribution of a specific vascularpattern. The model tests the relative role of the elastic organizationof the skin, the interrelation between skin tension line orientation andpedicle axis, and the apparently random proliferation of the branchingvascular pattern
