In some examples, a system includes an implantable medical device configured for implantation in a chamber of the heart, an extension attached to the implantable medical device, the extension comprising a housing comprising at least one electrode, the housing defining a hole, and a tether comprising a first tether portion and a second tether portion and configured to be threaded through the hole. When the tether is threaded through the hole, the first tether portion and the second tether portion are on opposite sides of the hole. The tether may be used to implant the extension in a different chamber of the heart of the patient than the implantable medical device.

Some embodiments relate to wearable technology. An example embodiment includes a garment that includes a panel, a sensor, a flexible display device, and a communication module. The panel includes an outer surface. The sensor is integrated into the garment and configured to collect data. The flexible display device is integrated into the outer surface of the panel. The flexible display device is configured to receive and display data. The communication module is communicatively coupled to the flexible display device, the sensor, and a programmable device and is configured to receive data from the programmable device and sensed data from the sensor and to communicate the received data and the sensed data to the flexible display device.

A method of stimulation therapy and an apparatus for providing the therapy which addresses cardiac dysfunction including heart failure. The therapy employs atrial pacing pulses delivered to a heart after the atrial refractory period and timed so that they will not cause a ventricular contraction. These atrial pacing are timed to achieve beneficial effects on myocardial mechanics (efficacy) while maintaining an extremely low level of risk of arrhythmia induction. These methods may be employed individually or in combinations in an external or implantable ESS therapy delivery device.

A single-pass pacing lead capable of sensing and pacing both the atria and the ventricles is described. In some examples, the single-pass pacing lead is connected to a DDD pacemaker. In some examples, the single-pass pacing lead comprises four electrodes. In some examples, the lead includes three electrodes configured to be positioned in or near an atrium, e.g., the right atrium, and one electrode configured to be positioned in or near a ventricle, e.g., the left ventricle, when the lead is implanted. In other examples, the lead includes two electrodes configured to be positioned in each of the atrium and ventricle when the lead is implanted. In some examples, one of the electrodes, which is configured to be positioned proximate the coronary sinus ostium when the lead is implanted, comprises a helical element for fixation of the lead to tissue.

An integrated bipolar implantable medical electrical lead, which may be employed by a cardiac defibrillator, has a single low voltage electrode and a single high voltage electrode and employs a relatively robust and fail-safe configuration of three conductors. Each of the three conductors extends within an individual lumen of a tri-lumen insulative body of the lead. First and second conductors of the three connect, in parallel, the low voltage electrode to a first contact of a connector terminal assembly of the lead, and a third conductor of the three connects the high voltage electrode to a second and a third contact of the connector terminal assembly. A configuration of the third conductor differs from that of the first and second conductors in order to make the third conductor more susceptible to fracture, relative to the first and second conductors, after many years of chronic implant under extreme loading conditions.

An implantable medical device includes an energy storage device with an internal component and an outer case that encloses the internal component. The outer case is electrically connected to the internal component. The energy storage device includes a first electrode that is electrically connected to the internal component. Furthermore, the device includes a control assembly with a control component and a control case that encloses the control component. The control case is coupled to and electrically connected to the outer case. The control component is electrically coupled to the first electrode and the outer case to be powered by the internal component of the energy storage device. The control component controls transmission of an electrical signal between the implantable medical device and biological tissue. Also, an outer surface of the outer case and the outer surface of the control case are exposed to the biological material.

An implantable medical device is configured so that all of the major components including a housing and attached leads are disposed within the vasculature of a patient. A tether extends from the housing of the device to an implant location where the tether is secured to tissue outside of the vasculature. In this manner, an intravascular medical device may be implanted at a location remote from final placement, delivered via the vasculature and anchored at the initial entry point.

Intravascular medical device

An extra-systolic stimulation (ESS) therapy addresses cardiac dysfunction including heart failure. ESS therapy employs atrial and/or ventricular extra-systoles via pacing-level stimulation to a heart. These extra-systoles must be timed correctly to achieve beneficial effects on myocardial mechanics (efficacy) while maintaining an extremely low level of risk of arrhythmia induction and excellent ICD-like arrhythmia sensing and detection (security). The present invention relates to therapy delivery guidance and options for improved ESS therapy delivery. These methods may be employed individually or in combinations in an external or implantable ESS therapy delivery device.

This invention securely holds a fishing rod and reel in a variety of situations and automatically sets the fishing hook when a fish strikes the baited hook or lure. Adapters hold the vertical stand either on a pond bank, a boat or dock rail, or dock flooring. The vertical stand pivotally supports a rod and reel holder, which is configured to hold the fishing tackle securely and without damage. The fishing line is looped under the trigger lever, which is raised and rotated by the pull on the fishing line when a fish strikes the bait. The catch arm is released as the trigger lever is lifted. The rod and reel holder is spring loaded and pivots around the support point when the catch arm is released, thus snapping to a more upright position, which action sets the hook.

A capacitor-discharge implantable cardioverter defibrillator (ICD) has a relatively smaller mass of less than about 120 grams. The smaller mass of the ICD is achieved by selecting and arranging the internal components of the ICD to deliver a maximum defibrillation countershock optimized in terms of a minimum physiologically effective current (I.sub.pe), rather than a minimum defibrillation threshold energy (DFT). As a result of the optimization in terms of a minimum effective current I.sub.pe, there is a significant decrease in the maximum electrical charge energy (E.sub.c) that must be stored by the capacitor of the ICD to less than about 30 Joules, even though a higher safety margin is provided for by the device. Due to this decrease in the maximum E.sub.c, as well as corollary decreases in the effective capacitance value required for the capacitor and the net energy storage required of the battery, the overall displacement volume of the ICD is reduced to the point where subcutaneous implantation of the device in the pectoral region of human patients is practical. The size of the capacitor is reduced because the effective capacitance required can be less than about 125 .mu.F. By optimizing both the charging time and the countershock duration for the smaller maximum E.sub.c, the size of the battery is reduced because the total energy storage capacity can be less than about 1.0 Amp-hours. In the preferred embodiment, the charging time for each defibrillation countershock is reduced to less than about 10 seconds and the pulse duration of the countershock is reduced to less than about 6 milliseconds.
