Patent number: 7241344Abstract: An apparatus and method for electrostatic spray deposition of small targets, such as medical devices like stents. The apparatus includes a target holder which applies a first electrical potential to the target, and an electrostatic dispensing nozzle which applies a second potential sufficient to attract the coating fluid from the nozzle toward the target. Because the entire dispensing nozzle is conductive, the coating fluid may receive a greater charge than may be obtained with internal electrode-type nozzles. Electrostatic attraction of the coating fluid to the target is enhanced by the combination of higher charge density imparted to the coating fluid by the conductive nozzle, and application of a momentary voltage spike to the target to provide consistent conductivity between the target and its holder, thereby ensuring the target is presents the full first potential applied to the holder. The voltage spike may also be used independently of the conductive nozzle.Type: GrantFiled: February 10, 2004Date of Patent: July 10, 2007Assignee: Boston Scientific Scimed, Inc.Inventors: Robert Worsham, James G. Hansen

Patent number: 5562208Abstract: A tool bit storage case includes a front cover preferably hingedly interconnected with a back cover, with the covers being selectively separable and movable toward and away from each other between open and closed positions and together defining a generally hollow storage chamber therebetween. A removable pivotable tools bit holder is releasably retained within the hollow storage chamber on one of the covers and is adapted for holding one or more tool bits, with the tool bit holder being pivotal within the storage chamber in order to allow it to be selectively pivoted toward and away from the cover upon which it is retained when the covers are in the open position. The covers are also releasably snapped together, into and out of their preferred hinged interconnection, thus greatly contributing to the interchangeability of components to suit a wide variety of storage applications.Type: GrantFiled: August 28, 1995Date of Patent: October 8, 1996Assignee: Black & Decker Inc.Inventors: Theodore J.
