Improved testing of medical devices, in particular medical devices providing wireless communication capabilities. A communication link between a medical device under test and the communication tester is established and a signal quality indicator of the established communication link is monitored while interfering the communication link by one or more interfering signals.

An implantable medical device (IMD) includes one or more stimulation engines (SEs) and selectively connectable output switching circuitry for driving a plurality of output nodes associated with a respective plurality of electrodes of the IMD's lead system when implanted in a patient. The output switching circuitry may be configured to facilitate self-test mode (STM) functionality in the IMD (e.g., when it is in a hermetically sealed package) by using a dual mode switch in series with a stimulation engine selection switch with respect to each output node in the output switching circuitry under mode selection control.

A power control circuit for use with devices that will be placed in a flammable sterilizing gas includes a bi-stable switch that is configured to produce an output to place the circuitry of a connected device in a run state or a sleep state. The bi-stable switch controls one or more transistors to drain energy from energy storage devices in the circuitry of the connected device to a level below an ignition level of a sterilizing gas. A remotely actuatable switch can be actuated from outside of a packaging in which the power control circuit is placed to cause the bi-stable switch to produce an output that puts the circuitry in the run state without removing the power control circuit from the packaging.

The disclosure provides a soak tester apparatus for testing an implantable enclosure having an impedance engine, a multiplexer and a removably attached cartridge, which cartridge has a plurality of threads, comprising a Faraday cage housing; a receptacle disposed within the Faraday cage housing, wherein the receptacle is configured to host an implantable enclosure having an impedance engine, a multiplexer and a removably attached cartridge, which cartridge has a plurality of threads; and a pigtail disposed within the Faraday cage housing having a charging coil configured to power the implantable enclosure.

The present invention relates to a preoperative test method, to an implantation system (20) and to an implantation method for implanting a neuroprosthesis in the area of the pubic bone (31), wherein implantation is ultimately simplified and made more effective directly or indirectly by the subject-matters of the invention.

A medical device control unit is provided. The control unit may include a communications interface, a memory, and at least one processing device. The processing device may be configured to cause application of a control signal to a primary antenna associated with a unit external to a subject's body. The processing device may further be configured to monitor a feedback signal indicative of the subject's breathing and store, in the memory, information associated with the feedback signal. The processing device may also cause transmission of the stored information, via the communications interface, to a location remote from the control unit. The processing device may further be configured to receive an update signal, from the location remote from the control unit, and cause application of an updated control signal to the primary antenna based on the update signal.

A capacitive test apparatus for testing an electronic device contained within a package, the apparatus comprising: a plurality of conductive pads in electrical communication with the processor, wherein the plurality of conductive pads are configured to align with electrodes of the electronic device during testing and capacitively couple electrical stimuli to the electrodes via the package; processing circuitry configured to: apply the electrical stimuli to the plurality of conductive pads; receive one or more response signals induced by the electrical stimuli coupled through the package; and determine one or more electrical characteristics of the electronic device based on the one or more response signals.

Various embodiments of a sealed package and a method of forming such package are disclosed. The package can include a non-conductive substrate that includes a cavity disposed in a first major surface. A cover layer can be disposed over the cavity and attached to the first major surface of the non-conductive substrate to form a sealed enclosure. The sealed package can also include a feedthrough that includes a via between a recessed surface of the cavity and a second major surface of the substrate, and a conductive material disposed in the via. An external contact can be disposed over the via on the second major surface of the non-conductive substrate, where the external contact is electrically connected to the conductive material disposed in the via. The sealed package can also include an electronic device disposed within the sealed enclosure that is electrically connected to the external contact.
