The method also includes the LP sensing a signal indicative of cardiac activity of the patient over a plurality of cardiac cycles, and outputting one or more conductive communication pulses, during a portion of at least one of the cardiac cycles, wherein the portion of the at least one of the cardiac cycles is identified based on the signal that is sensed and the information that is stored.

A helix antenna structure includes loop antennas and a multilayered printed circuit board including printed circuit board layers. Each printed circuit board layer includes a peripheral loop antenna and each adjacent two loop antennas are electrically connected by a connection bridge functioning as a monopole antenna. A selected printed circuit board layer physically and electrically accommodates a transmitter inside ‘its’ peripheral loop antenna, and it further includes a first antenna feeding line which is connected to the loop antenna that is disposed on the selected printed circuit board layer and electrically connectable to a first output terminal of the transmitter. A second antenna feeding line is disposed on another printed circuit board layer and electrically connected to its loop antenna and connectable to another output terminal of the transmitter. The two antenna feeding lines lie in a plane perpendicular to an axis of the printed circuit board after its folding.

Methods and apparatuses (e.g., devices and systems) for vagus nerve stimulation, including (but not limited to) sub-diaphragmatic vagus nerve stimulation. In particular, the methods and apparatuses described herein may be used to stimulate the posterior sub-diaphragmatic vagus nerve to treat inflammation and/or inflammatory disorders. The implantable microstimulators described herein may be leadless and batteryless.

Methods for manufacturing implantable electronic devices include forming an antenna of the implantable electronic device by delivering an antenna trace within a dielectric antenna body. The antenna trace includes a first trace portion disposed in a first transverse layer and defining a first trace path and a second trace portion disposed in a second transverse layer longitudinally offset from the first transverse layer and defining a second trace path. If projected to be coplanar, the first trace path defines a trace boundary and the second trace path is within the trace boundary.

An illustrative cochlear implant system is disclosed herein. The cochlear implant system comprises a microphone assembly including a microphone and a retention device configured to hold the microphone near an entrance to an ear canal of an ear of a recipient. The cochlear implant system further comprises an off-the-ear (OTE) sound processor that includes a housing configured to be worn off the ear of the recipient and further configured to physically attach to the microphone assembly so as to allow the microphone assembly to be worn off the ear when the microphone assembly is not being worn at the ear using the retention device. Corresponding systems and methods are also disclosed.

Power is transmitted to an implanted receiving coil oriented such that an axis of the receiving coil is parallel to skin of a subject. A transmitting coil is in a housing, which is placed against the skin. A central axis of the transmitting coil is perpendicular to the skin. A portion of the transmitting coil is over the receiving coil. A first distance, from the axis of the transmitting coil to a center of the receiving coil, is greater than a second distance, from the axis of the transmitting coil to an inner edge of the portion of the transmitting coil. The first distance is less than a third distance, from the axis of the transmitting coil to an outer edge of the portion of the transmitting coil. Circuitry powers the implant by driving current through the transmitting coil that induces current in the receiving coil.
