  • Patent number: 9254202
    Abstract: The present invention relates to method for loading a beneficial agent into an expandable medical device. The method includes the steps of sealing a plurality of openings extending through the medical device from a first side to a second side with a sealing member to substantially prevent a beneficial agent from passing through the openings, partially filling the openings with the beneficial agent delivered from an automated micro-jetting dispenser, substantially solidifying the beneficial agent, and removing the sealing member from the plurality of openings.

  • Patent number: 8986775
    Abstract: A system for delivery of a beneficial agent in the form of a viscous liquid or paste allows holes in a medical device to be loaded in a single step process. The loading of a beneficial agent in a paste form also provides the ability to deliver large and potentially sensitive molecules including proteins, enzymes, antibodies, antisense, ribozymes, gene/vector constructs, and cells including endothelial cells.

  • Patent number: 8011316
    Abstract: A machine and process useful for processing a delicate workpiece, e.g., an implantable medical device, includes a carrier having a mandrel and wheels. The workpiece is positioned on the mandrel, which is free to roll by gravity on rails which cooperate with the wheels to self-align the travel of the carrier. The carrier can move the workpieces through a series of processing steps by gravity feed and without human intervention. A laterally movable carriage receives the rolling carriers and moves the carrier for processing, and returns the carrier to the rails to again roll by gravity to another processing substation for additional processing. An elevator, which can including processing units itself, is positioned along the rails to receive carriers and raise them so they can continue to roll for further processing.

  • Patent number: 7927650
    Abstract: The beneficial agent is applied into the holes in a medical device in a dry particulate form and is adhered in the hole in a manner that allows release of the drug in a controlled manner. The drug material would be formed into particles and placed in the holes. The solvent would be added to partially liquefy and adhere the drug into the holes. After application of the solvent, the particles are adhered together in a substantially uniform drug containing matrix. The particles may include drug alone or drug in combination with other materials including a matrix.

  • Patent number: 7622029
    Abstract: An electropolishing device for polishing a cylindrical medical device such as a stent includes anodes in the form of rollers arranged to contact an exterior surface of the device. A drive mechanism rotates the anodes periodically during the electropolishing process to change a contact point between the anodes and the medical device. A tilting mechanism can also be used for periodically tilting the anodes during the electropolishing process to allow bubbles to escape from one end of the stent.
