Abstract
A personalized prosthesis for implantation at a treatment site of a patient includes a self-expanding mesh or membrane having collapsed and expanded configurations. The collapsed configuration is adapted to be delivered to the treatment site, and the expanded configuration engages the personalized prosthesis with the treatment site. The mesh or membrane is personalized to match the treatment site in the expanded configuration, and has an outer surface that substantially matches the treatment site shape and size. The self-expanding mesh or membrane forms a central lumen configured to allow blood or other body fluids to flow therethrough. Methods of manufacturing and delivery of the personalized prosthesis are also disclosed.
Claims25
A method for manufacturing a personalized prosthesis, said method comprising:
- providing one or more images of a treatment site in a patient, the treatment site having a shape and volume;
- creating a digital data set characterizing the shape and the volume of the treatment site based on the one or more images;
- transforming the digital data set into machining instructions;
- forming a mandrel using the machining instructions, wherein the mandrel has a shape and a volume that substantially matches the shape and the volume of the treatment site;
- applying a mesh to the mandrel, 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;
- heat treating the mesh while the mesh is disposed over the mandrel so that the mesh has a shape matching the shape and the volume of the treatment site thereby forming the personalized implantable prosthesis, the personalized prosthesis having a contracted configuration and an expanded configuration,
- wherein the personalized implantable prosthesis is adapted to be delivered to the treatment site in a contracted configuration, and
- wherein the personalized prosthesis is biased to return to the expanded configuration, the expanded configuration having the shape matching the shape and volume of the treatment site.
