  • Patent number: 8372424
    Abstract: This invention relates to stable non-aqueous single phase viscous vehicles and to formulations utilizing such vehicles. The formulations comprise at least one beneficial agent uniformly suspended in the vehicle. The formulation is capable of being stored at temperatures ranging from cold to body temperature for long periods of time. The formulations are capable of being uniformly delivered from drug delivery systems at an exit shear rate of between about 1 to 1×10?7 reciprocal second.
    Type: Grant

  • Patent number: 8366738
    Abstract: Disclosed is an apparatus and a method for removable of undesired material from body lumens. The apparatus may be used for fragmenting or removing a thrombus or occlusion from a blood vessel. The apparatus includes first shape segments and second shape segments connected to form a coiled member. A longitudinally extending tether is positioned inside the first shape segments and outside the second shape segments along the length of the coil. Applying a proximal force on the tether produces a change in the shape of at least a portion of the coil from a first generally linear configuration to a second complex three dimensional shape. A method of using the apparatus to engage and remove, or fragment, the thrombus or occlusion is disclosed.

  • Publication number: 20120259373
    Abstract: Described herein are devices, systems and methods for treating disease and/or infection by the release of silver from an implant over an extended period of time. In particular, the devices described herein may be used to treat infections such as osteomyelitis by the controlled release of silver ions from multiple sites of an extended-use implant. This implant typically includes a plurality of arms that both anchor and help distribute the released ions within the tissue. Power may be applied to release the silver ions into the tissue.

  • Publication number: 20120123485
    Abstract: Silver and/or zinc ion releasing implants, systems and method of operating, inserting and activating/inactivating them are described. In some variations the implant is configured as a bone implant that includes a bone-screw or intramedullary rod like body configured to receive a treatment cartridge having a plurality of ion-releasing members configured as an anode that can controllably engage with a catheter to turn galvanic release of ions on/off as desired. These devices may be configured to release silver ions (and/or zinc ions) above a predetermined level for a predetermined period of time and may maintain a concentration of ions over a relatively large volume of tissue. The ion-releasing members may be configured to reduce or prevent implant movement.

  • Patent number: 8172897
    Abstract: A device and a method of manufacturing an implantable medical device, such as a stent, are described herein. The device includes a metallic region composed of a bioerodable metal and a polymer region composed of a biodegradable polymer contacting the metallic region. The metallic region may erode at a different rate when exposed to bodily fluids than the polymer region when exposed to bodily fluids. In certain embodiments, the polymer region is an outer layer and the metallic region is an inner layer of the device. A further aspect of the invention includes device and a method of manufacturing the device that includes a mixture of a biodegradable polymer and bioerodable metallic particles. The mixture may be used to fabricate an implantable medical device or to coat an implantable medical device. In some embodiments, the metallic particles are metallic nanoparticles.
