Publication number: 20240108467Abstract: Delivery apparatus and methods for delivering a medical device into a patient's vasculature are disclosed. In some examples, a method includes inserting, into a patient, a distal end portion of a delivery apparatus including a radially compressed prosthetic valve mounted around a balloon, advancing the distal end through the patient's vasculature, and inflating the balloon to radially expand the prosthetic valve at a native heart valve. The delivery apparatus includes a handle, a first shaft and a second shaft extending from the handle, and a locking mechanism to prevent axial movement of the second shaft relative to first shaft. The second shaft extends coaxially through the first shaft and includes the balloon, the radially compressed prosthetic valve, and one or more radiopaque markers at a distal end portion. The first shaft includes an end piece covering a proximal portion of the balloon during the advancing of the delivery apparatus.Type: ApplicationFiled: December 14, 2023Publication date: April 4, 2024Inventors: Philippe Marchand, David M.

Patent number: 6234807Abstract: A printed circuit board connector edge tab design has increased tab contact area with a large local capacitance at the connector interface. This serves to balance out the inductive effects of the connector and results in a lower overall channel impedance at the interface. The invention replaces the prior art plated pathway to the upper row of tabs with wider tabs on the lower row. The edges of the lower row tabs are spaced such that each of the connector pins destined for the upper row straddle two of the lower tabs as they travel upward. This design prevents the pins from contacting the fiberglass substrate of the board while it traverses the lower row of tabs. The absence of the prior art plated pathways allows each of the lower row tabs to be expanded into the space formerly occupied by the pathways. This design also allows the increased capacitive area of the edge tabs to be located in very close proximity to the connection area between the connector pins and the edge tabs.Type: GrantFiled: January 24, 2000Date of Patent: May 22, 2001Assignee: International Business Machines CorporationInventors: Kamran Amini, Joseph Curtis Diepenbrock, Robert J.

Patent number: 5507468Abstract: The present invention is directed to an integral bi-directional flow control valve. The valve includes a housing that defines a passageway for the flow of a fluid in a first direction and a second direction. The housing defines a phase change chamber in the passageway. A first restrictor having a first bore is positioned in the passageway adjacent the phase change chamber. The bore has a volume less than the volume of the chamber. As the fluid flows through the bore in the first direction into the chamber, the fluid changes from a liquid to a gas as it exits the bore. The gas continues to flow through the passageway. A second restrictor having a second bore is positioned in the passageway adjacent the chamber and opposed to the first restrictor. The second restrictor includes a second bore having a volume less than the volume of the chamber. The second bore can be the same size as the first bore or a different size depending on the application.Type: GrantFiled: January 12, 1995Date of Patent: April 16, 1996Assignee: Aeroquip CorporationInventor: Robert J.
