Abstract: A method and computer program for calculating proximal and distal ends of an interlaced device before being positioned in a vascular structure are proposed. The method comprises receiving a three-dimensional image of a vascular structure in which an interlaced device with a singularity at a proximal and/or distal end will be positioned. A central line of said structure which defines a direction in which the interlaced device is to be deployed is traced. A point Pd on the traced central line and the local morphology of the vessel are defined, wherein point Pd indicates the point where the distal end of the interlaced device will start to be deployed. A proximal point Pp is calculated using the distal point Pd and the local morphology of the vessel, both having been defined. The proximal and distal ends are calculated depending on if the singularity is at the proximal and/or distal ends.

Abstract: A method, system and computer program are provided for determining the porosity of a flexible porous structure when it is subjected to deformation. The method performs the following steps by processing representative data of the flexible porous structure: a) generates a first function (Fs) defining how the flexible porous structure changes shape when it is subjected to deformation; b) generates a second function (Fp) defining how a covered surface of the flexible porous structure changes when it is subjected to changes in shape, wherein the second function (Fp) is directly linked with porosity of the flexible porous structure; c) obtains reference porosity values of a reference region (CU-R) of the flexible porous structure in a reference configuration via the first function (Fs); and d) calculates the porosity of at least one deformed region (CU-D) of the flexible porous structure, from said reference porosity values and from the second function (Fp).
