Abstract
In-vivo biodegradable medical implants, containing at least in part at least partially fine-grained metallic materials that are strong, tough, stiff and lightweight, are disclosed The in-vivo biodegradable implants are used in a number of stent applications, for fracture fixation, sutures and the like. The in-vivo biodegradable medical implants enable the reduction of implant size and weight and consequently result in reducing the release of implant degradation products into the body
Claims14
A biodegradable medical implant comprising
- (a) from 5 to 100% by weight or volume of a metallic material and
- (b) from 95 to 0% by weight or volume of a polymeric material;
- where from 5 to 100% of the metallic material has a crystalline microstructure with an average grain size ranging from 2 nm to 10 μm;
- said implant having a thickness ranging from 5 μm to 2.5 cm;
- the metallic material, average grain size and thickness being such that the implant degrades entirely in-vivo in a time ranging from one month to twelve months.
