Abstract: Auto-injectors can deliver many different types of medicines into people. One failure mode of auto-injectors is failing to insert the needle into the patient while the medicine is propelled from the auto-injector. This error results in the medicine not entering the patient's body. An auto-injector can include a syringe and probes to prevent medicine from being propelled if the person administering the injection does not position the auto-injector correctly.

Abstract: An implantable cardiac monitoring device includes first and second arms, pivotably attached to one another; electronic circuitry and an associated power source of the device are hermetically sealed in a housing formed by one of the arms. A first electrode is carried by the first arm, a second electrode by the second arm, and a third electrode by one of the two arms. The device further includes a tether element, preferably a strut, pivotably attached between the arms and movable between a folded state and an expanded state. When the strut is in the folded state, the device, in a relatively compact form, can be inserted through a relatively small incision and into subcutaneous tissue, after which, the strut is moved to the expanded state where ends of the arms are spaced apart from one another and supported by the strut, and the three electrodes form dual sensing vectors.

Abstract: Low voltage conductors in a lead assembly share a lumen in a tube and are separated from adjacent conductors in the tube by an insulative layer. In an embodiment, low voltage conductors are combined with high voltage conductors. In another embodiment, low voltage conductors are combined with other low voltage conductors.

Abstract: This document discusses, among other things a cardiac lead with first and second electrodes electrically interconnected by back-to-back diodes or another conductivity control device. During sensing of intrinsic electrical heart signals, these electrodes are isolated from each other by the conductivity control device. This reduces noise during sensing. During pacing or defibrillation, these electrodes are electrically connected to each other by the conductivity control device. When used in common as a return path electrode, this avoids unintentional stimulation of the heart at the return path electrode instead of at the stimulating electrode. The electrodes can also share a common conductor from one of the electrodes back to a proximal end of the lead.
