A leadless cardiac pacemaker device is configured to provide HIS bundle pacing and contains a housing having a tip, a first electrode arranged on the housing in the vicinity of the tip, the first electrode being configured to engage with intra-cardiac tissue, and a second electrode arranged on the housing at a distance from the tip of the housing. A processor is enclosed in the housing and operatively connected to the first electrode and the second electrode. The processor is configured to process a reception signal received by at least one of the first electrode and the second electrode and to generate a pacing signal to be emitted using at least one of the first electrode and the second electrode.

Insertion tool

An intracardiac pacemaker device, comprising a housing that is configured to be implanted entirely within a ventricle (V) of a heart (H), an electronic module for generating pacing pulses, a battery for supplying energy to the electronic module, an elongated lead extension protruding from the housing, at least a first electrode arranged on the elongated lead extension, and a pacing electrode and a return electrode for applying the pacing pulses to cardiac tissue, wherein the pacing electrode is arranged on the housing. The electronic module is electrically coupled to the pacing electrode via the housing, and wherein the electronic module is configured to carry out measurements of electrical activity via the at least one first electrode of the elongated lead extension.

Intracardiac pacemaker device, particularly for VDD or VDDR pacing

An implantation tool for implanting a medical device subcutaneously includes a core extending along a longitudinal axis. The core is formed with a longitudinal recess extending along the longitudinal axis. A shell protrudes from an end of the core in the direction of the longitudinal axis. The shell defines a compartment for carrying the medical implant. The compartment is connected to the longitudinal recess. A rod that extends along the longitudinal axis is arranged in the longitudinal recess.

Tools and method for subcutaneous device insertion

A biventricular (BiV) implantable cardiac stimulator contains a stimulation control unit, one or more stimulation units, an impedance measurement unit and an impedance evaluation unit. The stimulation control unit is operatively connected to one or more stimulation units to control delivery of stimulation pulses by the one or more stimulation units. The stimulation control unit is configured to assess ventricular contractility based on an impedance signal generated by the impedance evaluation unit and to switch between at least a univentricular left ventricular stimulation mode and a biventricular stimulation mode and to evaluate the ventricular contractility in relation to the respective ventricular stimulation mode.

Various embodiments are directed toward a system and method for determining an orientation of an implantable medical device ('IMD') and automatically adjusting a subcutaneous electrocardiogram ('ECG') signal based on the determined orientation. The method can further include tagging generated SECG signals so as to identify whether a SECG signal had been generated from an implantable monitoring device with its first electrode being superior or inferior relative to its second electrode. Further embodiments can include automatically adjusting the orientation of the generated SECG signals to match that of a preferred orientation.

Automatic orientation of subcutaneous ECG in implantable monitoring devices

In an electrostimulator which applies electrical stimulation to patient tissue, measurements of lead impedance (tissue resistance), battery status, and like matters are used to format and/or truncate the ranges of programmable therapeutic output settings available for selection by a clinician. The clinician can therefore better tell whether chosen settings can actually be successfully implemented, and/or whether they may have adverse effects on device lifespan or patient safety.

Enhanced therapy settings in programmable electrostimulators

An implantable medical device including a data communication interface connected to a pulse generator. The pulse generator generates and delivers forward current pulses and reverse current pulses, wherein a polarity of the reverse current pulses is opposite to the polarity of the forward current pulses. Generates pulses representing binary digits, wherein a first kind of digits (1 or 0) is represented by a current pulse, and a second kind of digit respective of the other type of binary digits (0 or 1) is represented by a pause between current pulses. The data communication interface together with the pulse generator deliver current pulses with strictly alternating polarity such that every other current pulse is a reverse current pulse of opposite polarity compared to an immediately preceding forward current pulse. Thus, every string of current pulse is both, charge balancing and information encoding.

Insertion tool for an implantable monitoring device

A sterilizable containment that includes an inner packaging and an outer packaging. The outer packaging encloses the inner packaging and includes at least two electric feedthroughs. The inner packaging includes at least two electric contacts, wherein each of the at least two electric contacts of the inner packaging matches one of the at least two electric feedthroughs of the outer packaging to provide an electric connection between a respective feedthrough and the corresponding contact when the inner and the outer packaging are closed. Each of the contacts of the inner packaging feed electrical charge from outside of the inner packaging to the inside of the inner packaging and vice versa. The inner packaging includes electrically conducting media that allows propagation of electrical charge between the contacts of the inner packaging and an implantable medical device included inside in a packaging when the containment is filled.

Tunneling tool for an implantable monitoring device

An implantable medical device includes an actuator and/or sensor portion to be fixed to bodily tissue by means of a fixation mechanism, to act on the tissue and/or to detect a signal from the tissue, wherein at least one detector element, preferably a plurality of detector elements, adapted for detecting the close proximity of bodily tissue, is arranged on the actuator and/or sensor portion of the device, and an output of the or each detector element being connected or connectable to a detection signal evaluation unit for deriving a fixation state verification from detection signals provided by the or each detector element.

Implantable cardiological monitoring device

Implantable electromedical device or loop recorders or ILRs that solve the problem of very low arrhythmia detection specificities in, i.e., high number of false positives, based on detection and analysis of external noise, specifically muscle noise surrounding the electromedical device. Embodiments generally employ active detection of lead or device movement that induces signal artifacts indicative of external noise. One or more embodiments may detect lead or device movement through use of a piezoelectric transducer, for example located proximally to the device or in the lead of the electromedical.
