  • Patent number: 9159203
    Abstract: An automated teller machine is proposed having at least one camera to detect manipulation attempts that captures images of one or more elements arranged in the control panel, such as a keypad, cash-dispensing drawer, card entry slot and generates image data from a plurality of individual image recordings (F1, F2, F3). The at least one camera is connected to a data processing unit that preprocesses the image data generated (individual image data) into a resulting image (R). The preprocessed image data of the resulting image (R) can be computed, for example, by exposure blending from the individual images (F1, F2, F3) and represent a very good data base for data evaluation to detect manipulation.

  • Publication number: 20150272758
    Abstract: A delivery device for a collapsible prosthetic heart valve includes an operating handle and a catheter assembly. The operating handle may include a housing defining a movement space therein, a carriage assembly moveable in a longitudinal direction within the movement space, a deployment actuator coupled to the housing and rotatable relative to the housing, and a coupling assembly rotationally fixed to the deployment actuator. The catheter assembly may include a first shaft around which a compartment is defined and a distal sheath operatively connected to the carriage assembly. Movement of the carriage assembly in the longitudinal direction in the movement space may move the distal sheath between the closed condition and the open condition. The coupling assembly may have an engaged position in which rotation of the deployment actuator moves the carriage assembly, and a disengaged position in which rotation of the deployment actuator does not move the carriage assembly.

  • Patent number: 8953045
    Abstract: The invention proposes an automated teller machine having different control elements, such as a card entry slot (4), for example, wherein at least one camera (CAMK) is integrated in a control element, the card entry slot (4), for example, and captures images of a plurality of sub-regions attributed to said control element (4), such as an interior region, outer region and overhead region. Lighting (L) that illuminates one or some of the partial regions, the interior region or the slit region of the card entry slot (4), for example, can also be arranged, thereby also improving the image. In addition, the construction can be furnished with a light-conducting material (K) over which light produced by the lighting (L) can be guided and distributed.

  • Patent number: 8893370
    Abstract: An assembly for collapsing a self-expanding prosthetic heart valve includes a compression member, a support member, a constricting member, and a spacer which may be used for smaller sized heart valves. The compression member has a tapered wall between its first open end and its second open end, the tapered wall defining an open space adapted to receive the heart valve. The support member has a base and a recess adapted to receive an end of the heart valve. The support member and the compression member are movable toward one another to compress the heart valve and push it through a relatively small aperture in the second open end of the compression member. The second end of the constricting member is sized to receive the compressed heart valve from the second open end of the compression member for loading into a delivery device.

  • Patent number: 8882708
    Abstract: In general, this disclosure relates to techniques for providing a mating mechanism between at least one pressurizing unit and at least one corresponding sleeve in a powered medical fluid injection device. An example powered medical fluid injection device includes a sleeve and an injector head coupled to the sleeve. The sleeve has a notch with a predefined shape and size. The sleeve is configured to receive a pressurizing unit (such as a syringe) having an external tab with a predefined shape and size that are substantially identical to the predefined shape and size of the notch in the sleeve, such that the tab mates with the notch when the sleeve receives the pressurizing unit. The injector head is configured to inject a quantity of a medical fluid from the pressurizing unit during operation.

  • Publication number: 20140236225
    Abstract: A vascular closure system includes a balloon location device, a bioadhesive delivery device, and a sealing tip. The balloon location device includes a balloon for temporarily sealing a vessel puncture internally and at least one lumen for delivering inflation fluid to the balloon. The bioadhesive delivery device includes at least one lumen for delivery of the balloon location device to the vessel puncture. One of the balloon location device and the bioadhesive delivery device includes a first lumen for delivery of a first volume of bioadhesive to the vessel puncture. The sealing tip is releasable within a channel formed in the first volume of bioadhesive upon withdrawal of the balloon. One of the balloon location device and the bioadhesive delivery device is configured for delivery of a second volume of bioadhesive to the vessel puncture after the sealing tip is released in the channel.

  • Patent number: 8740877
    Abstract: In general, this disclosure relates to techniques for implementation and use of a fluid connection assembly, having a locking mechanism, which may be connected to a medical fluid injection device. An example fluid connection assembly includes at least one fluid connector, a mating mechanism coupled to the at least one fluid connector and configured to connect the at least one fluid connector to a medical fluid injection device, and a locking mechanism coupled to the mating mechanism and movable into a locked position or an unlocked position. In this example, the fluid connection assembly becomes affirmatively coupled with the medical fluid injection device when the locking mechanism is in the locked position, and the fluid connection assembly becomes removably decoupled from the medical fluid injection device when the locking mechanism is in the unlocked position.

  • Publication number: 20140039263
    Abstract: An introducer includes a housing and a flexible seal. The housing includes a hub, a cap, and a lumen. The flexible seal is positioned across the lumen and retained between the hub and the cap. The seal includes a top surface and a bottom surface, a bottom slit formed in the bottom surface, and a top slit formed in the top surface. The top slit crosses the bottom slit. The seal member is biased by an interface between the hub and the cap to at least partially close the top slit and at least partially open the bottom slit.

  • Patent number: 8419676
    Abstract: In general, this disclosure relates to techniques for sealing, or pinching, high-pressure fluid tubing (e.g., braided tubing) that may be used to deliver medical fluid from a powered medical fluid injection device, such as an injector that delivers contrast media and/or saline during angiographic or computed tomography (CT) procedures. In some cases, one or more low-friction, solenoid-based pinch valve mechanisms may be used. One example powered medical fluid injection device comprises an injector head and at least one pinch valve mechanism that is coupled to the injector head. The at least one pinch valve mechanism comprises a plunger, a reciprocating arm driven by the plunger, and a tube pinching area. The at least one pinch valve mechanism, when deactivated by the injector head, is configured to cause the reciprocating arm to pinch fluid tubing that runs through the tube pinching area.
