  • ASSEMBLY AND METHOD OF IMPLANTING A HEART ASSIST SYSTEM
    Publication number: 20120296151
    Abstract: A needle guard is used when suturing the cuff of an attachment ring to the heart. The needle guard is disposed in the attachment ring to prevent other parts of the attachment ring from being punctured by a suturing needle. The needle guard can include one or more grooves to inhibit relative movement between the needle guard and the attachment ring during suturing. The needle guard is removed upon completion of suturing and to allow insertion into attachment ring of an inflow conduit of a heart assist device. An articulated clamp is used to compress the attachment ring into engagement with the inflow conduit. The attachment include an annular rib that grabs the inflow conduit.

  • CONTROL VALVE ASSEMBLY FOR ELECTRO-HYDRAULIC STEERING SYSTEM
    Publication number: 20110284311
    Abstract: A steering system includes a fluid pump and an electro-hydraulic steering circuit in selective fluid communication with the fluid pump. The electro-hydraulic steering circuit defines a first flow path having a first proportional valve and a first load-sense passage in selective communication with the first proportional valve. The first proportional valve includes a closed position. A hydrostatic steering circuit is in selective fluid communication with the fluid pump and defines a second flow path having a second proportional valve and a second load-sense passage in selective fluid communication with the second proportional valve. The second flow path is in a parallel flow configuration with the first flow path. An isolation valve is disposed in the first flow path in series with the first proportional valve. The isolation valve includes a closed position and is piloted to the closed position by fluid communicated through the second load-sense passage.

  • Selectively Coating Luminal Surfaces of Stents
    Publication number: 20110073036
    Abstract: With abluminal side of a stent masked, the luminal side of the stent is selectively coated with a substance, such as an anti-coagulant, a platelet inhibitor and/or a pro-healing substance. The stent can be masked by inserting it into a rigid mandrel chamber or by compressing a masking sleeve onto the outer side of the stent. A spray nozzle inserted into the masked stent spray coats the substance onto the luminal side. The sprayed coating can be cured onto the stent such as by inserting an electrical-resistance heater bar into the stent.
