摘要：
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.
