An implantable medical device (IMD) can include a cardiac pacemaker or an implantable cardioverter-defibrillator (ICD). Various portions of the IMD, such as a device body, a lead body, or a lead tip, can be provided to reduce or dissipate a current and heat induced by various external environmental factors. According to various embodiments, features can be incorporated into the lead body, the lead tip, or the IMD body to reduce the creation of an induced current, or dissipate the induced current and heat created due to an induced current in the lead. For example, an IMD can include at least one outer conductive member and a first electrode. The first electrode can be in electrical communication with the at least one outer conductive member. The first electrode can dissipate a current induced in the at least one outer conductive member via a first portion of the anatomical structure.

The present application relates to an electrode pad comprising at least one electrode with an electrode terminal. A contact member such as a hydrogel is disposed on said electrode terminal and covered by a retainer mesh. The electrode terminal may be, for example, a silver electrode disposed on a flexible foil, and the contact member may be disposed in the aperture of a backing layer. The retainer mesh is designed to allow for an electrical contact of the contact member to an object such as the body of a person while at the same time mechanically retaining the contact member. Moreover, the electrode pad may comprise an array of several electrodes disposed on a carrier, said carrier having a slit separating at least two neighboring electrodes.

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 flexible substrate has a first surface and a second surface, and includes an electrical circuit configured to electronically couple the electronic device to at least one of an electrode a battery, or an antenna. The flexible substrate is coupled to the base such that a first portion of the second surface is in contact with the first protrusion. A second portion of the second surface is non-parallel to the first portion.

A system for supplying power transcutaneously to an implantable device implanted within a subject is provided. The system includes an external connector including one of a microneedle array and a microwire holder. The system further includes a power cable electrically coupled to the external connector and configured to supply power to the one of the microneedle array and the microwire holder, and an internal connector configured to be implanted within the subject and electrically coupled to the implantable device, the internal connector including the other of the microneedle array and the microwire holder. The microneedle array includes a plurality of electrically conductive microneedles, the microwire holder includes a plurality of electrical contacts, and the microwire holder is configured to engage the microneedle array such that the plurality of electrically conductive microneedles extend through the skin of the subject and electrically couple to the plurality of electrical contacts.

In an embodiment, an electrical stimulation system can include one or more of an electrode assembly including one or more electrodes and an electronics subsystem. In some variations, each of the one or more electrodes can include a hydrophilic layer and a conductive layer. In some variations, the electronics subsystem can include one or more of a control module, power module, and a stimulus generator. In some variations, the electrical stimulation can further include one or more of an electrical attachment system, mechanical attachment system, head apparel assembly, flexible housing, and/or any other suitable component.
