  • Publication number: 20140214156
    Abstract: An apparatus for replacing a diseased cardiac valve is movable from a radially collapsed configuration to a radially expanded configuration. The apparatus comprises an expandable support member and a prosthetic valve secured therein. The main body portion extends between first and second end portions and includes an outer circumferential surface, a circumferential axis extending about the circumferential surface, and a plurality of wing members spaced apart from one another by an expandable region. Each of the wing members includes first and second end portions and a flexible middle portion extending between the end portions. The second end portion is integrally formed with the uyimain body portion. The first end portion is adjacent the circumferential axis and substantially flush with the outer circumferential surface in the radially collapsed configuration. The first end portion extends substantially radial to the outer circumferential surface in the radially expanded configuration.

  • Publication number: 20140189816
    Abstract: A server-based desktop-virtual machines architecture may be extended to a client machine. In one embodiment, a user desktop is remotely accessed from a client system. The remote desktop is generated by a first virtual machine running on a server system, which may comprise one or more server computers. During execution of the first virtual machine, writes to a corresponding virtual disk are directed to a delta disk file or redo log. A copy of the virtual disk is created on the client system. When a user decides to “check out” his or her desktop, the first virtual machine is terminated (if it is running) and a copy of the delta disk is created on the client system. Once the delta disk is present on the client system, a second virtual machine can be started on the client system using the virtual disk and delta disk to provide local access to the user's desktop at the client system. This allows the user to then access his or her desktop without being connected to a network.

  • Publication number: 20140094836
    Abstract: Disclosed is a pericardiocentesis needle component (10), comprising a guide wire (13) and a puncture needle (12). The guide wire (13) extends into and through the puncture needle (12), and the guide wire (13) comprises a bent section (32) at the distal end and a straight section at the proximal end. The bent section (32) at the distal end is formed by bending the guide wire (13), and the end of the bent section is a pointed-shape structure. The guide wire (13) is made of a highly elastic material. The pointed end rotates at least 90 degrees within a range of no more than 3 mm starting from the pointed end at the bent section (32) of the guide wire. The pericardiocentesis needle component (10) of the present invention is less likely to damage a heart during a pericardiocentesis procedure.

  • Publication number: 20130238088
    Abstract: A method is provided for implanting a valve having at least one valve leaflet within the cardiovascular system of a subject. One step of the method includes preparing a substantially dehydrated bioprosthetic valve and then providing an expandable support member having oppositely disposed first and second ends and a main body portion extending between the ends. Next, the substantially dehydrated bioprosthetic valve is attached to the expandable support member so that the substantially dehydrated bioprosthetic valve is operably secured within the main body portion of the expandable support member. The expandable support member is then crimped into a compressed configuration and placed at a desired location within the cardiovascular system of the subject. Either before or after placement at the desired location, fluid or blood re-hydrates the substantially dehydrated bioprosthetic valve.
