US 10,246,763 B2 · Magnesium-zinc-strontium alloys for medical implants and devices

Abstract

A medical implant and/or device, which includes a biodegradable and cytocompatible magnesium-zinc-strontium alloy is disclosed. The implant and/or device can include a biodegradable and cytocompatible magnesium-zinc-strontium (Mg—Zn—Sr) alloy having a weight percent composition of Zn and Sr as follows: 0.01≤Zn≤6 wt %, 0.01≤Sr≤3 wt %. A method for manufacturing an implant in the form of a biodegradable and cytocompatible magnesium-zinc-strontium alloy is disclosed, which includes melting the biodegradable and cytocompatible magnesium-zinc-strontium alloy in an inert environment and molding the biodegradable magnesium-zinc-strontium alloy in a semi-solid state.
