  • Patent number: 10195015
    Abstract: A stent graft includes a tubular graft element to which there are attached a plurality of stent rings. The stent rings are formed of a plurality of stent struts arranged in a zig-zag arrangement with alternating peaks and valleys. The end-most stent is located at the proximal end of the graft tube. Between adjacent peaks of the end most stent, there is provided a series of bridging elements. These are preferably formed of Nitinol wire and to be substantially more flexible than the stent struts. The bridging elements extend in the region of graft material between adjacent stent peaks and are attached to the graft material, for example by suturing. The bridging elements are substantially more flexible than the stent ring and therefore impart little opening force on the graft material in comparison to the force produced by the stent ring. However, the bridging elements impart enough force on the flaps of graft material between the peaks of the stent ring keep these flaps open, that is against the vessel wall.

  • Publication number: 20190003607
    Abstract: The invention relates to a capsule for a valve as well as to a valve comprising such a capsule. The task of the present invention is to provide a valve in which tight tolerances for construction can be achieved and the assembly of the valve is simplified. According to the present invention the above task is solved by a capsule (1) for a valve comprising at least one diaphragm (2), a valve seat (3), a capsule inlet (5) and a capsule outlet (6). The valve seat (3) is openable and closable to permit or stop a fluid flow from the capsule inlet (5) to the capsule outlet (6). The above task is also solved by a capsule (1) for a valve that comprises at least one diaphragm (2), a valve seat (3), a capsule inlet (5) and a capsule outlet (6), wherein the capsule (1) is structured and arranged to control the position of a pilot valve element external to the capsule (1).

  • Patent number: 10117736
    Abstract: The disclosure provides a filter apparatus and method of filtering in a body vessel. The filter apparatus comprises a filter unit and an expandable introducer designed to deliver the filter unit to the target filtering site. The filter unit attaches to the expandable introducer via a plurality of anchors on the filter unit. The expandable introducer delivers and presses the anchors to the vessel wall during implantation. After implantation, the filter unit exerts minimal or about zero radial force against the vessel wall.

  • Publication number: 20180250732
    Abstract: A method of making a self-expanding stent entails applying a bend stress sufficient to over-bend a portion of a wire by an amount in a range from about 85% to about 105%, where the wire comprises a Ni—Ti alloy and includes from about 40% to about 46% cold work. The bend stress is then released, thereby forming a bend having a predetermined bend angle in the wire. The application and release of the bend stress are repeated on successive portions of the wire in order to create a series of bends along a length of the wire in a predetermined bend pattern. The wire comprising the predetermined bend pattern is then positioned about a mandrel in an expanded stent geometry and heat set. Thus, a self-expanding stent is formed.

  • Patent number: 9717611
    Abstract: A stent graft (40) for treating Type-A dissections in the ascending aorta (22) is provided with a plurality of diameter reducing suture loops (56-60) operable to constrain the stent graft during deployment thereof in a patient's aorta. The diameter reducing loops (56-60) allow the stent graft (40) to be partially deployed, in such a manner that its location can be precisely adjusted in the patient's lumen. In this manner, the stent graft can be placed just by the coronary arteries (26, 28) with confidence that these will not be blocked. The stent graft (40) is also provided with proximal and distal bare stents (44,52) for anchoring purposes.

  • Patent number: 9486343
    Abstract: A pre-loaded stent graft delivery device and stent graft, the stent graft delivery device. The stent graft has at least one fenestration or side arm and the fenestration is preloaded with an indwelling guide wire. Indwelling access sheaths are provided within auxiliary lumens of a pusher catheter and dilators are preloaded into the access sheaths along with the indwelling guide wire. A handle assembly at a distal end of the guide wire catheter. The handle includes a multiport manifold with access ports to the auxiliary lumens in the pusher catheter. Upon deployment of the stent graft into the vasculature of a patient, the indwelling guide wire can be used to facilitate cathertization of a side branch or target vessel through the fenestration or be used to stabilize the access sheath during catheterization, advancement of the access sheath into the target vessel and deployment of a covered or uncovered stent therein through the access sheath.

  • Patent number: 9393096
    Abstract: A filter device for trapping embolic debris comprises a bag which is deployed by everting it from an end of a delivery catheter. After release from the catheter, with the assistance of a pusher member, the open end of the bag self-expands against the walls of a body lumen. In one method of removal after use, the device is withdrawn into catheter by pulling on a wire attached to the closed end of the bag.

  • Patent number: 8974157
    Abstract: An adjustable cargo storage press for organizing and securing cargo items stored in a cargo storage area of an automobile. The adjustable cargo storage press is disposed within or integrated with a cargo area of an automotive vehicle such as a trunk, bed or bed liner of a car, truck, or sport utility vehicle. The press prevents movement of cargo items and potential damage to the cargo items during transport. The press also maintains the position of the cargo items for easy removal from the cargo storage area. The press includes one or more hinged walls that lock in a vertical position and move towards each other along guide tracks. The one or more hinged walls compress the cargo items between the hinged walls, and fold flat when not in use so as not to limit cargo storage capacity of the cargo storage area.

  • Patent number: 8857889
    Abstract: A door check system includes a rod interconnecting a door assembly and a body of a vehicle. The door check system secures the position of the door assembly at any location along a swing path of the door assembly, between a fully open position and a fully closed position. A coil spring is disposed about the rod, with the rod extending through a central aperture thereof. An actuator is coupled to the coil spring and configured for tightening and loosening the coil spring about the rod. When the actuator tightens the spring about the rod, the spring grasps the rod and secures the position of the door assembly relative to the body. When the actuator loosens the spring from about the rod, the door assembly is free to move along the swing path.
