Abstract: An implantable electrical stimulating device and system provides for a remote determination of the identity of the person in whom the stimulating device is implanted. The stimulating device may be a pacemaker, a defibrillator, another medical device or a non-medical device. The bases for the remote identification are (1) the comingling of (A) biologic identification information of the person linked to the stimulating device, and (B) information pertaining to a physiologic parameter (e.g. heart rate information) of that person, and (2) the modulation of the physiologic parameter by external information. Embodiments of the invention in which the stimulating device is external to the person are possible. By utilizing the apparatus providing for the remote identification of a person plus stimulating device, one aspect of secure communication—that based on reliable mutual identification of each participant in a communication—is achieved.

A wrist mounted version may alarm drivers or others requiring focus or concentration when they fall asleep and may alert a medical center. The invention may have a pulse oximeter on a person's wrist/finger to monitor their breathing while asleep, and in the event of a serious snoring or sleep apnea episode, activate the breathing assistance pulses.

Abstract: A system and method for accelerating confirmation of cardiac arrhythmias is provided. The system includes memory to store specific executable instructions. One or more processors are configured to execute the specific executable instructions for obtaining a far field cardiac activity (CA) data set that includes far field CA signals for a series of beats. The CA data set includes a first CA data subset and a remainder CA data subset. The system analyzes the CA data set for an arrhythmia of interest utilizing a primary detection process having primary criteria. During a first phase of the primary detection process the system analyzes the first CA data subset to determine whether the first CA data subset satisfies at least a portion of the primary criteria. When the first CA data subset satisfies at least the portion of the primary criteria, the system initiates a secondary confirmation process.

Abstract: Systems and methods are provided for applying electrical stimulation to a body by an electrode spaced from a target nerve of passage. It has been discovered that pain felt, or perceived to be felt, in a given region of the body can be treated by stimulating muscle close to a “nerve of passage” in a region that is superior (i.e., cranial or upstream toward the spinal column) to the region where pain is felt, such as in a case of post-amputation residual limb pain, or purportedly felt in the case of post-amputation phantom limb pain.

A stimulation therapy lead includes helical electrodes configured to conform to an outer diameter of a cervical vagus nerve sheath, and a set of connector pins electrically connected to the helical electrodes. A neurostimulator includes an electrical receptacle into which the connector pins are securely and electrically coupled. The neurostimulator also includes a pulse generator configured to therapeutically stimulate the vagus nerve through the helical electrodes in alternating cycles of stimuli application and stimuli inhibition that are tuned to both efferently activate the heart's intrinsic nervous system and afferently activate the patient's central reflexes by triggering bi-directional action potentials.

Abstract: Methods of treating pain are disclosed, wherein a non-pulsed, low-frequency electrical current is applied to the nerve carrying the pain signals in order to suppress transmission of those signals. In desired embodiments, the current is applied in a direction transverse to the nerve axis. Such currents have been found not to induce motor-neuron recruitment, meaning these methods can treat pain without causing muscle spasm or other muscular responses. A cuff for applying such a current transverse to the nerve axis is also disclosed.

Abstract: Implantation of a cardiac stimulus system using the intercostal veins. Superior, intercostal, and inferior access methods are discussed and disclosed. Superior access may be performed by entering the brachiocephalic vein from a jugular, subclavian, or other vein, and then accessing the internal thoracic vein, traversing a portion of the internal thoracic vein and then accessing an intercostal vein therefrom. Inferior access may be accomplished inferior to the lower rib margin via the superior epigastric vein, advancing superiorly into the internal thoracic vein and then accessing an intercostal vein therefrom. Intercostal access may include creating an opening in an intercostal space between two ribs and advancing a needle using ultrasound guidance to enter the intercostal vein directly.

Abstract: An external defibrillator system is configured with at least two different algorithms for determining the duration of a shock administered to a patient being treated and selects the algorithm based on one or more patient parameters such as, for example, the patient's TTI. The patient's TTI can be measured prior to or while the shock is being administered to the patient. The shock can be, for example, a multiphasic defibrillation or a multiphasic cardioversion shock. The charge voltage of the system's energy storage device can additionally be varied depending on the one or more patient parameters. For example, the system may charge the energy storage device so that the charge voltage is higher or lower than a nominal charge voltage responsive to the patient's TTI is higher or lower compared to an average TTI, respectively.
