  • Patent number: 7715923
    Abstract: High reliability electrical connections between a helical strand and flat electrodes, such us strip electrodes found in implantable neurostimulator system, are described. The connection consists of a crimp joint in which an inside diameter mandrel is used to provided the coil with sufficient radial rigidity to ensure structural integrity of the crimp. The mandrel is made of a relatively soft biocompatible material that deforms rather than damages the fine wires of the helical strand during crimping. The crimping is accomplished by radial deformation of an annular or semi-annular crimping member that receives the helical strand/mandrel assembly.

  • Publication number: 20090285714
    Abstract: Implantable medical devices made from a single beta phase Tantalum alloy utilizing Titanium as an alloying agent that are biocompatible, radiopaque and visible under x-ray and fluoroscopy, the alloy having mechanical properties that allow it to be machined by conventional, machining methods for forming the devices, and a method for making the alloy. The alloy is between approximately 10 percent and 25 percent Ti by weight and preferably has a density of 12 g/cm3 or greater.

  • Publication number: 20060286288
    Abstract: A process for improving the adhesion of polymers to metal surfaces includes a highly porous layer that is condensed onto a metal substrate to provide a strong bond between the metal substrate and the highly porous layer. A polymer adhesive is deposited on top of the highly porous layer, where the polymer adhesive bonds to the pores that exist in the highly porous layer, improving the adhesion of the polymer adhesive to the metal substrate.

  • Patent number: 5648327
    Abstract: Disclosed are aqueous liquid detergent compositions comprising dispersed particles of a silicone-based suds suppressor system and a separately added moderately hydrophobic particulate silica stabilizing agent. Such a separately added stabilizing agent serves to retard coalescence and coagulation of the suds suppressor particles and thus enhances the storage stability of the suds suppressor-containing detergent compositions of this invention.
