Publication number: 20180325712Abstract: Catheter for delivery of a medical device such as a stent or filter includes an inner tubular member and an outer tubular member movable relative to the inner tubular member. The outer tubular member is disposed at the distal end of the inner tubular member. The inner tubular member includes a fluid lumen defined therein, the fluid lumen having a fluid flow port directed to the exterior surface of the inner tubular member. A pressure chamber is defined by the inner tubular member, the outer tubular member, a proximal seal and a distal seal, and is in fluid communication with the fluid flow port, wherein fluid introduced through the fluid flow port and into the pressure chamber applies a force on the proximal seal to move the outer tubular member in a proximal direction allowing the medical device constrained by the outer tubular member to be released.Type: ApplicationFiled: July 24, 2018Publication date: November 15, 2018Applicant: ABBOTT CARDIOVASCULAR SYSTEMS INC.Inventors: Michael R. Bialas, John E. Papp, John Simpson, Wouter Erik Roorda, Matthew Gillick, Michael L. Green, David P. Strauss, Duane M. DeMore, Robert P. Barbier, Marc Gianotti

Patent number: 8658006Abstract: A system and method is described for electropolishing tubular metallic prostheses. In one aspect, the system provides a continuously changing set of points of contact between anode and prosthesis. In another aspect, the cathode is given a conical shape to correct for current concentrations that would otherwise exist and unevenly affect the amount of electropolishing over the length of the prosthesis.Type: GrantFiled: April 12, 2010Date of Patent: February 25, 2014Assignee: Abbott Cardiovascular Systems Inc.Inventors: Michael R.

Patent number: 6733641Abstract: A target assembly in which the sputtering material is not soldered or otherwise metallurgically bonded to a backing plate. Rather, the target, which is homogeneously manufactured of sputtering material, is mechanically coupled (e.g., with bolts) to an adapter, which is itself permanently affixed to the chamber. As a result, the target can be easily uncoupled from the chamber and replaced, without also requiring removal and replacement of a backing plate.Type: GrantFiled: June 25, 1997Date of Patent: May 11, 2004Assignee: Praxair S. T. Technology, Inc.Inventors: David P. Strauss, Thomas J. Hunt, Paul S. Gilman

Patent number: 4924368Abstract: A shatter-containment fluorescent lamp having a protective plastic sleeve in which the sleeve is attached by an adhesive at each end of the lamp envelope in a manner to provide a controlled air space between the glass lamp envelope and the plastic sleeve to prevent direct transmission of stresses from the envelope to the sleeve. The sleeve is also attached to the lamp base by the adhesive so that there is integral connection of the sleeve and the base at each end of the envelope. A retaining ring, also held by the adhesive, covers the base. In a preferred embodiment of the invention, the retaining ring inner surface and the lamp base having mating members to align the retaining ring on the base. In another embodiment, the sleeve has a number of angled slots around its circumference at each end and there are corresponding locking teeth on a retaining ring to accommodate for variations in lamp envelope/protective sleeve length.Type: GrantFiled: January 6, 1989Date of Patent: May 8, 1990Assignee: Duro-Test CorporationInventors: Donald P. Northrop, David P. Strauss
