A subcutaneously implantable device includes a housing, a clip attached to a top side of the housing, a first prong with a proximal end attached to the housing and a distal end extending away from the housing, and a first electrode on the first prong. The clip is configured to anchor the device to a muscle, a bone, and/or a tissue. The first prong is configured to contact a heart. The first electrode is configured to contact the heart. Sensing circuitry in the housing that is configured to sense an electrical signal from the heart, and therapeutic circuitry in the housing is in electrical communication with the first electrode and is configured to deliver electrical stimulation to the heart through the first electrode.

An implantable medical device for implantation into a patient comprises a body, an anchoring device for anchoring the body to tissue at a location of interest, the anchoring device being arranged on the body, and an electrode device for at least one of emitting an electrical stimulation signal and sensing an electrical sense signal. The electrode device comprises at least one electrode and a helically extending coil body, wherein the electrode device is movable with respect to the body between a retracted position, in which the electrode device at least partially is received within the body, and an engagement position, in which the electrode device is moved to protrude from the body to engage with tissue.

In some examples, an implantable medical device (IMD) includes a housing defined in part by a longitudinal axis, a header at a distal end of the housing, the header defining a header plane, the header plane disposed at an angle relative to a reference plane, where the reference plane is perpendicular to the longitudinal axis, a fixation mechanism extending from the header, the fixation mechanism configured to be advanced into tissue of a heart of a patient to fix at least a portion of the IMD to the heart, one or more electrodes that extend from the header and are configured to engage with the septum, and circuitry within the housing, wherein the circuitry is configured to deliver cardiac pacing to the heart via the one or more electrodes.

A neurostimulation system is shown and described. The neurostimulation system may include a stimulation device implantable into a patient, a lead operatively coupled with the stimulation device, a first power cell providing power to the stimulation device where the first power cell is charged by an externally applied AC (High HF) magnetic field.

An implantation system and methods of inserting an implant are disclosed. The method includes the step of making an incision in an abdominal wall with an instrument positioned within an abdominal cavity. The method further includes the steps of forming a pocket between a first surface of the abdominal wall and a second surface of the abdominal wall, such that the incision defines an opening into the pocket, inserting an implant through the opening and into the pocket, and closing the opening such that the implant is captured within the pocket.

In an embodiment herein, an aortopulmonary stimulation method is provided including positioning at least one aortic electrode in or near the aorta, and using the at least one aortic electrode, to deliver stimulation to the aorta to decrease aortic after load.

This document describes implantable medical devices and methods of using such devices. The implantable medical devices include a cardiac lead sized for insertion in a cardiac cavity, the cardiac lead having a distal end and a proximal end and a lead body extending therebetween, a heat exchange module disposed at the distal end of the lead body, the heat exchange module comprising an enclosure having a first surface and a second surface, and one or more temperature sensors located within the enclosure.

This disclosure relates to a communication amplification device for an implantable capsule, in particular for an autonomous cardiac stimulation capsule. The amplification device comprises a first holding element and a second element configured to hold the implantable capsule. The first holding element is configured to receive the distal end of the capsule and the second holding element is configured to receive the proximal end of the capsule. The first holding element comprises a communication amplification antenna configured to couple to a distal electrode of the capsule.

A cochlear implant includes a cochlear lead, a housing, an antenna, a stimulation processor operably connected to the antenna and to the cochlear lead, a first fixation element, a second fixation element with a different configuration than the first fixation element, and a connector configured to simultaneously connect the first and second fixation elements to the housing in such a manner that the first and second fixation elements are independently detachable from the housing.

A control module for an electrical stimulation system includes a sealed electronics housing; an electronic subassembly disposed within the electronics housing; one or more connector assemblies coupled to the electronic subassembly; and a rechargeable battery disposed external to the electronics housing. The one or more connector assemblies are configured to receive a lead. The rechargeable battery includes a positive electrode, a negative electrode, and a single battery case attached directly to the sealed electronics housing and forming a sealed cavity that encapsulates both the positive electrode and the negative electrode. The battery case is electrically isolated from each of the positive electrode and the battery electrode.
