  • Publication number: 20110125263
    Abstract: A method for treating a surface of a medical implant to create nanostructures on the surface that results in increased in-vivo chondrocyte adhesion to the surface. Further, disclosed is a method to fabricate a drug delivery system. The drug delivery system includes a medical implant that has undergone a surface treatment process that results in the modification of the surface configuration and topography. The modified surface acts as a depot or reservoir for loaded biological material, biologic agents or pharmaceutical products. Additionally, a device for delivering pharmaceutical products or other biological materials is disclosed. The device includes integrally attached nanostructures that retain or adsorb the loaded pharmaceutical products and/or biological materials. Further disclosed is a medical implant that includes a surface configured to allow for and regulate protein adsorption.

  • Publication number: 20100081108
    Abstract: An adapter for use with an air/water tip (e.g., a three-way dental syringe). The adapter comprises a body including a proximal end and a distal end, a mixing chamber disposed between the proximal and distal ends, a water delivery lumen for delivering water from a coupleable fluid dispensing device to the mixing chamber, and a separate air delivery lumen for delivering air from a coupleable fluid dispensing device to the mixing chamber. The cross-sectional area of the water delivery lumen at a location adjacent the mixing chamber is greater than the cross-sectional area of the air delivery lumen at a location adjacent the mixing chamber. The relative cross-sectional areas act to balance pressures of air and water entering the mixing chamber so as to provide a ratio of volumetric flow rate of water to air that is between about 0.5:1 to about 2:1.
