Abstract: Disclosed herein are representative embodiments of methods, apparatus, and systems used to deliver a prosthetic heart valve to a deficient valve. In one embodiment, for instance, a support structure and an expandable prosthetic valve are advanced through the aortic arch of a patient using a delivery system. The support structure is delivered to a position on or adjacent to the surface of the outflow side of the aortic valve (the support structure defining a support-structure interior). The expandable prosthetic valve is delivered into the aortic valve and into the support-structure interior. The expandable prosthetic heart valve is expanded while the expandable prosthetic heart valve is in the support-structure interior and while the support structure is at the position on or adjacent to the surface of the outflow side of the aortic valve, thereby causing one or more native leaflets of the aortic valve to be frictionally secured between the support structure and the expanded prosthetic heart valve.

Abstract: A current tester includes: a probe, a computing device for converting a voltage drop across a component to a current, and an output device for signaling a presence or non-presence of current. The computing device stores a pre-determined voltage drop/current relationship for the component. A method for detecting current in a circuit includes: connecting a current tester to the component, measuring a voltage drop across the component, converting the voltage drop to a current via the current tester, and producing a signal by the current tester indicating a presence or non-presence of current in the circuit. A method for detecting current in a circuit may also comprises: connecting probes of a testing device to a component in the circuit; determining via whether the probes are properly connected to the component; and determining a voltage drop across the component to determine the presence or non-presence of current.

Abstract: A testing device for a relay includes an enclosure for containing a circuit that includes at least one electrical socket adapted for selective engagement with a connector of the relay, a power source, a testing indicator LED adapted to convey a testing results indication, a power switch, and a testing IC adapted to run a series of tests on the relay when the relay is engaged with the at least one socket. In use, with the connector of the relay engaged with the at least one socket, power may be applied to the circuit such that the testing IC runs the series of tests on the relay by alternately activating and deactivating the coil power lines and measuring the resulting state of the armature line, the normally open signal line, and if available the normally closed signal line of the relay.

Abstract: A device and methods for detecting current changes over a preset threshold in a circuit are provided. The device includes a housing for securing at least a circuit board therein. The device further includes at least one alerting device in electrical communication with and controlled by a micro-controller. The device also includes at least one input device fixed with the housing and configured so that a user may set conditions for the micro-controller. The meter also includes at least one detecting device for measuring a current reading in a circuit, and in electrical communication with the micro-controller. The micro-controller stores a current reading in the memory and the micro-controller then compares subsequent current readings to the stored current readings to calculate a current change. If the current change is greater than the preset threshold, the micro-controller activates the at least one alerting device.
