The present invention includes devices and methods for pacing contact, lead, conduit or other medical fixture placement in tissues or organs. The invention features an articulating multiple suction foot device, comprising an inner vacuum conduit and foot slidingly contained within an outer vacuum conduit and foot, with the inner vacuum conduit and foot configured to extend beyond the outer vacuum suction foot, and to be further articulated once extended; as well as a separate tissue or waste removal vacuum assembly that extends within the inner vacuum conduit to the inner vacuum foot to remove cut tissue prior to its advancement beyond the outer vacuum suction foot. The device is configured to permit the placement foot, such as a suction foot, to articulate to a desired position with respect to the target tissue, while the pacing contact, lead, fluid conduit or other medical fixture is releasably attached to the placement foot to permit it to be released from the placement foot after stabilization on the target tissue site.

The present disclosure relates generally to pacing of the cardiac conduction system of a patient, and more particularly, to providing adaptive cardiac conducting system pacing therapy and to determining selective or non-selective capture of the cardiac conduction system by cardiac conduction system pacing therapy. The adaptive cardiac conduction system pacing therapy may adjust AV delay and VV delay based on various signals and metrics and may switch between cardiac conduction system pacing therapy exclusively and cardiac conduction system pacing therapy in combination with traditional left ventricular pacing therapy.

Introducers for implanting a lead having a fixation element distal to an electrode include a window, electrode, or conductive member alignable with the electrode of the lead white maintaining the fixation element in a retracted configuration. The window, electrode or conductive member of the introducer provide a mechanism for applying test stimulation signals to determine whether the lead is properly positioned in a patient without deploying the fixation element.

A subcutaneous implantable medical device and method (SIMD) provided. A pulse generator (PG) is configured to be positioned subcutaneously within a lateral region of a chest of a patient. The PG has a housing that includes a PG electrode. The PG has an electronics module. An elongated lead is electrically coupled to the pulse generator. The elongated lead includes a first electrode that is configured to be positioned along a first parasternal region proximate a sternum of the patient and a second electrode that is configured to be positioned at an anterior region of the patient. The first and second electrodes are coupled to be electrically common with one another. The electronics module is configured to provide electrical shocks for antiarrhythmic therapy along at least one shocking vector between the PG electrode and the first and second electrodes.

An electrode (10) for treating organic tissue by means of direct current, comprising an electrode holder (20), at least one electrically conductive electrode surface (30), which is let into the electrode holder (20), wherein the at least one electrode surface (30) is connected to at least one control element (400) and wherein the at least one control element (400) is connected to a control and energy supply unit by way of electrical lines (60, 70), wherein the at least one control element (400) is configured in such a way that each individual electrode surface (30) is actuable by the at least one control element (400) in such a way that a current density (J) provided within a predetermined interval for each one of the at least one electrode surfaces (30) can be maintained or that a current density (J) for each one of the at least one electrode surfaces (30) can be maintained around a predetermined value.

A connector block that permits simultaneous and continuous interconnection of the three leads of the epicardial pacing wires, the pacemaker, and the ECG monitor on clear separately labeled connectors is provided. Circuitry is provided that allows the display of epicardial signals on the telemetry unit, while still preserving the ability to pace the heart from the pacemaker. When pacing the connector block prevents excessive loading of the pacer signals by the ECG monitor and/or damage to the monitor by the high-voltage pacer signals. The connector block may be used universally on all monitors without the need for sophisticated understanding of the electrical characteristics of the ECG monitor or concern for damage or improper signal loading.

A pacing lead for a left cavity of the heart, implanted in the coronary system. The lead includes a lead body with a hollow sheath of deformable material, having a central lumen open at both ends, and at least one telescopic microcable of conductive material. The microcable slides along the length of the lead body and extends beyond the distal end thereof. The part emerging beyond the distal end is an active free part comprising a plurality of distinct bare areas, intended to come into contact with the wall of a target vein of the coronary system, so as to form a network of stimulation electrodes electrically connected together in parallel. The microcable further comprises, proximally, a connector to a generator of active implantable medical device such as a pacemaker or a resynchronizer.

Embodiments include a medical implant including a fixing device with at least one fixing element to fix the implant at a site of implantation. The implant includes a belt drive that rotates an actuation device, wherein the actuation device is coupled to the fixing device and converts the rotary movement into a longitudinal movement of the fixing device. Embodiments include an insertion device to insert the medical implant.

Systems and methods are provided for delivering vagus nerve stimulation and cardioversion/defibrillation therapies to patients for treating chronic heart failure. The vagus nerve stimulation and cardioversion/defibrillation therapies may be provided using a single implantable pulse generator, which can coordinate delivery of the therapies to provide an acute vagus nerve stimulation therapy in advance of delivering cardioversion-defibrillation energy.

Injectable subcutaneous heart device (ISHD) for regulating arrhythmias in a heart of a patient, including a plurality of linked structures, each one of the linked structures being hollow, an interconnecting bus, a biocompatible coating, at least two electrodes and a plurality of sensors, the interconnecting bus for electrically coupling the linked structures and the biocompatible coating for hermetically sealing and electrically insulating the linked structures, one of the linked structures encapsulating a power source, another one of the linked structures encapsulating at least one capacitor and a third one of the linked structures encapsulating electronics, the electrodes and the sensors being respectively placed on an outer surface of the linked structures located at opposite ends of the ISH D, for detecting arrhythmias and providing electrical shocks to the heart, the electrodes and the sensors being electrically coupled with the interconnecting bus and the ISHD being positioned subcutaneously around the heart.
