Abstract

See full text

A method for improving bioactivity of a surface of an implantable object comprising titania, titanium, an alloy of titanium, and/or polytetrafluoroethylene (PTFE) and implantable objects prepared thereby provides forming an accelerated neutral beam derived from an accelerated gas-cluster ion-beam (GCIB) in a reduced-pressure chamber, introducing an implantable object into the reduced-pressure chamber, and irradiating at least a first portion of the surface of said implantable object with a GCIB-derived neutral beam.
