Publication number: 20110314754Abstract: The invention provides door frame assembly, suitable for hanging a door panel in a number of different positions. The invention is characterised such that a side wall of the frame is routered on front and rear faces, either face adapted to receive one plate of a door hinge. In addition one edge of the door panel is routered across the entire length of the edge to receive a second plate of said hinge, wherein the outer edge of the second plate comprises a bull nosed edge. The advantage of the door frame assembly according to the invention is the routering both sides of the panel allows it to be reversed depending on which way one wishes to hang the door. As the door panel edge is routered across the entire edge allows the hinge to hang the door in the frame in either direction.Type: ApplicationFiled: March 11, 2010Publication date: December 29, 2011Inventor: Stephen Griffin

Patent number: 7918806Abstract: A guide wire with a distal portion having adjustable flexibility. The guide wire may include a distal polymeric member and a heat source. The heat source may be activated to cause the polymeric member to increase in temperature and increase in flexibility. The increase in flexibility of the distal portion of the guide wire enhances the ability of the guide wire to navigate tortuous vasculature to a target site. After the guide wire has been navigated to the target site, the heat source may be deactivated to cause the polymeric member to decrease in temperature and increase in stiffness. The increase in stiffness of the distal portion of the guide wire enhances support provided for devices (e.g., catheters) advanced thereon.Type: GrantFiled: February 13, 2006Date of Patent: April 5, 2011Assignee: Boston Scientific Scimed, Inc.Inventors: Stephen Griffin, Gregory E. Mirigian

Publication number: 20110034989Abstract: A balloon catheter or stent delivery system for medical treatment of a patient has a proximal hub, a balloon, and an improved shaft design. The catheter shaft has a rapid-exchange configuration, and a tubular outer body that includes a hypotube extending from the catheter proximal end to a position at or near a proximal leg of the balloon. An inner tubular body defines a guidewire lumen extending from a distal guidewire port at the catheter distal end to a proximal port located at a position between the balloon and the hub. A distal leg of the balloon is directly or indirectly affixed to the inner body, and a proximal leg of the balloon is affixed to the distal end of the outer body. The hypotube has an aperture for accepting the inner body proximal end, and a circumferential cut pattern. The cut pattern adds flexibility, and may extend from the hypotube distal end to a position proximal of the proximal guidewire port.Type: ApplicationFiled: October 18, 2010Publication date: February 10, 2011Applicant: Cordis CorporationInventors: Laila Al-Marashi, David Grewe, Stephen Griffin, Elaine Lim, David Majercak, Roger Stevens
