  • Patent number: 8889211
    Abstract: A method of producing a drug coated balloon that comprises the steps of: subjecting a balloon catheter with a folded and wrapped balloon thereon to a pre-annealing step to induce a fold/wrap memory in the resulting pre-annealed balloon; unfolding the pre-annealed balloon sufficiently to expose the full circumferential surface of the balloon by application of an inflation pressure that retains said fold/wrap memory; applying a drug coating formulation to the unfolded balloon surface; releasing pressure to relax the balloon and induce creasing along fold memory; and evacuating the balloon slowly to induce refolding and rewrapping of the balloon. The method overcomes the need to use a folding apparatus to fold and wrap a drug coated balloon.

  • Patent number: 7494076
    Abstract: A secured method and pressing means for rendering data stored on a plurality of data storage devices unrecoverable. The method begins in a secure room where a mobile, relocatable hydraulic pressing means including at least one beveled bar is used for holding and crushing the plurality of data storage devices simultaneously. An activation device is connected to the mobile relocatable hydraulic pressing means enabling a user to send a signal to commence the destruction of the data storage devices to form debris. The debris is packed into storage containers and transported in a secure transport device to a location for secure storage or final disposition.

  • Publication number: 20070156205
    Abstract: An embodiment of a system for gathering physiologic data related to a human body includes a sensor device implanted in the human body, an inductive coil communicably coupled to the implanted sensor device; and a manager device in communication with the implanted sensor device via the inductive coil. The coil may be wrapped around the sensor device or attached to the sensor device fixation. An embodiment of a method for gathering physiologic data related to a physiologic parameter in a human body includes communicably coupling an inductive coil to communication circuitry of an implantable medical device (IMD), deploying the inductive coil and the IMD into a vessel of the human body, and inducing current in the inductive coil via the communication circuitry, the current representative of data associated with the IMD.
