Abstract
The method of assisting the production of an implantable unfurlable made to measure device comprises: three-dimensional reconstruction of a complex surface of the cavity in which the device will be implanted; Production of a first finite element mesh of this complex surface; Choosing of generic components of the device; Production of a second finite element mesh of these assembled generic components; Determination of the morphosis parameters for morphosing from the first mesh to a mesh of a set of simple linked volumes which is representative of the part of the cavity, and then deformation of the first mesh by this morphosis; Simulation of a deformation of the second mesh, by inverse morphosis dependent on the determined parameters, to the complex surface, simulating unfurling of the device; Determination of dimensioning of points of interest by projection onto the second deformed mesh; and Generation of a production blueprint plan of the device.
