1. A personalized prosthesis for implantation at a treatment site in a patient, said prosthesis comprising: a self-expanding mesh having a collapsed configuration and an expanded configuration, the collapsed configuration adapted to be delivered to the treatment site, and the expanded configuration adapted to expand the personalized prosthesis into engagement with the treatment site, wherein the mesh in the expanded configuration is personalized to match the treatment site, wherein the mesh in the expanded configuration has an outer surface that substantially matches the treatment site shape and size, wherein the self-expanding mesh forms a central lumen configured to allow blood or other body fluids to pass therethrough, wherein the self-expanding mesh comprises one or more apertures extending through a sidewall thereof, the one or more apertures fluidly coupled with the central lumen to allow blood flow or other fluid flow between the central lumen and the one or more apertures, the one or more apertures having a personalized position configured to accommodate side branch vessels or other body passages such that the prosthesis does not obstruct blood flow or fluid flow therethrough, and wherein the mesh in the expanded configuration and the personalized position of the apertures is determined using a digital data set characterizing the shape and volume of the treatment site, the digital data set created from one or more images of the treatment site, and wherein the mesh is formed from a plurality of filaments twisted together to form a repeating circumferential pattern of three twists followed by two twists followed by two twists.
