Abstract: A medical system includes a patient-applied part, a medical device, a power cable, and a patient-applied part cable. The medical device may include a device housing, a rechargeable battery within the device housing, a control circuit within the device housing, a power circuit within the device housing, and an electrical port on the device housing for use in making electrical connections to the control circuit and the power circuit within the device housing. The power cable may have a first end configured to be electrically connected to an electrical power line and a second end configured to be removably connected to the electrical port. The patient-applied part cable may have a first end configured to be electrically connected to the patient-applied part and a second end configured to be removably connected to the electrical port.

Abstract: A medical system may include an external medical device, at least two patient-applied parts, and a furcated cable having one proximal end configured to be connected to the external medical device and having at least first and second distal ends configured to be connected to the patient-applied parts. The cable may include first and second types of twisted wire pairs. The second type includes wires that have a lower gauge and higher current capacity than the first type. The cable may include at least four sets of twisted wire pairs, including at least two sets of twisted wire pairs of the first type and at least two sets of twisted wire pairs of the second type. Each of the first and second distal ends include a first type and a second type of twisted wire pairs.

Abstract: A system may include a headset band configured to be worn on a head of a patient, first and second arms, first and second coil assemblies, and at least one power supply electrically connected to the first coil assembly and the second coil assembly. The headset band may include a first end and a second end, and may be configured the first end to be on a first side of the head when the second end is on a second side of the head when worn on the head. The first arm may be rotatably connected to the headset band near the first end, and the second arm may be rotatably connected to the headset band near the second end. The first coil assembly may be connected to the first arm and the second coil assembly may be connected to the second arm.

Abstract: A therapy system for applying an electrical signal to an internal anatomical feature of a patient includes an implantable component and an external component. The implantable component is configured to receive a selected therapy program and a selected therapy schedule from the external component. The implantable component is adapted to be selectively configured into one of a training mode and a delivery mode. The implantable component is configured to apply therapy to the internal anatomical feature in accordance with the selected therapy program and the selected therapy schedule when configured in the delivery mode. The implantable component is configured to simulate application of therapy when configured in the training mode.

Abstract: Embodiments of an implantable medical device includes a loop antenna wound about an inner housing. The loop antenna may form a partial winding, a complete winding, or multiple windings about the inner housing. One or more additional antennae may be capacitively coupled to the loop antenna external to the inner housing to increase efficiency and decrease Return Loss Response of the implantable device. The additional antenna may be balanced or unbalanced antennae.

Abstract: A redundant alarm system including a central controller that interfaces with a first alarm, a second alarm, a visual indicator and an acoustic sensor. When an alarm condition exists, the controller activates the primary alarm causing the primary alarm to generate an audible first alarm signal. The audible first alarm signal is transmitted from the primary alarm to the acoustical sensor. The acoustical sensor detects the audible first alarm signal and transduces the audible first alarm signal into a first feedback signal that is relayed to the controller. If the controller does not receive the first feedback signal from the acoustical sensor within a predetermined time after activating the primary alarm, the controller activates the secondary alarm and the visual indicator.
