Abstract: An apparatus includes a manifold with a chamber for mixing multiple reactants. Gases are jetted into the manifold by a plurality of inlet injectors. The inlet injectors are arranged such that the gases passing into the manifold impinge on each other at a common point to form a mixture. The mixture passes through a plurality of holes in one side of the manifold into a deposition chamber where the mixture of gases impinges on additional gases at a common point to provide a reaction resulting in deposition of solid materials in the deposition chamber. The solid materials are free-standing.

Abstract: Methods of implanting, applying, or adhering various drug molecules directly into or onto the surface of medical devices through gas cluster ion beam (GCIB) and/or monomer ion beam surface modification of the medical devices before or after depositing the various drug molecules onto the medical devices.

Abstract: Regardless of the materials used in an artificial joint component design, the present invention applies gas cluster ion beam (GCIB) technology in order to modify the component's surface(s) so as to increase lubrication between contact surfaces, thereby substantially reducing wear debris, osteolysis complications, and accelerated wear failure. The approach of the surface modification comprises an atomic level surface patterning utilizing GCIB to apply a predetermined pattern to the surface(s) of the joint implant to reduce frictional wear at the interface of the surfaces. A reduction in wear debris by GCIB patterning on any surface(s) of a joint prosthesis reduces accelerated failure due to wear and osteolysis and results in a substantial cost savings to the healthcare system, and reduces patient pain and suffering.

Abstract: Medical devices implanted or otherwise used in a mammal are made less prone to trigger adverse reactions by use of gas cluster ion-beam (GCIB) surface modification and/or monomer ion beam surface modification to implant, apply, or adhere various drug molecules directly into or onto the surface of medical devices. This is accomplished without the need for a polymer or any other binding agent to retain the drug.

Abstract: The application of gas cluster ion beam (GCIB) technology in order to modify the surface of a surgical implant such as the components of an artificial hip joint, thereby substantially reducing wear debris and osteolysis complications is disclosed. The approach of the surface modification comprises an atomic level surface smoothing utilizing GCIB to super smooth the femoral heads and/or the surfaces of the acetabular cups to reduce frictional wear at the interface of the bearing surfaces. A reduction in polyethylene debris and metal debris by GCIB smoothing on one or both bearing surfaces of a surgical implant reduces osteolysis, results in a substantial cost savings to the healthcare system, and reduces patient pain and suffering.
