Abstract
A biocompatible polymer composition is disclosed comprised of high density polyethylene particles. The high density polyethylene particles when sintered into an article can promote vascular growth. For example, when molded into an article, the particles produce a porous structure particularly well suited for maxillofacial implants.
Claims22
A polymer composition for producing medical implants comprising:
- high density polyethylene particles, the particles having an average particle size (d50) of from about 300 microns to about 950 microns, and wherein the particles have a particle size distribution such that the high density polyethylene includes particles having a size less than about 300 microns and includes particles having a size of greater than about 1,000 microns, the high density polyethylene polymer having an average molecular weight of from about 300,000 g/mol to about 10,000,000 g/mol, the high density polyethylene having a melt flow rate of less than about 10 g/10 min at 190° C. and at a load of 21.6 kg when tested according to ISO Test 1133.
