Abstract
The invention relates to methods of manufacturing various medical devices and starting materials by utilizing the processes of high speed injection molding and slurry-based, semi-solid die casting applied to biocompatible metals or metal alloys that may have a high melting point temperature. These devices may be made fully consolidated or porous to allow the devices to act as a functional drug delivery vehicle.
Claims4
A method of making a medical device, comprising:
- providing a biocompatible material;
- casting a porous medical device from the biocompatible material by processing the biocompatible material into a thixotropic state;
- and
- impregnating the medical device with a drug wherein a binder material is injected into the thixotropic material in order to cast the porous medical device.
