Disclosed is a system for recharging a selected power source wirelessly, such as through a power transmission. The power source may be positioned within a subject and be charged wirelessly through the subject, such as tissue of the subject. A thermal transfer system is provided to transfer or transport thermal energy from a first position to a second position, such as away from the subject.

Systems, devices and methods are disclosed that allow recharging a power source located in an implanted medical device implanted in a patient, the recharging device comprising first and second pairs of electrical coils configured to generate first and second uniform magnetic fields in overlapping first and second cylindrical regions located between the respective pairs of electrical coils.

Provided herein are methods of treating a patient comprising providing a medical apparatus comprising an external system and an implantable system, implanting the implantable system, and delivering at least one of power or data to the implantable system with the external system. The external system comprises: at least one external antenna configured to transmit a first transmission signal to the implantable system; an external transmitter configured to drive the at least one external antenna; an external power supply; and an external controller. The implantable system comprises: at least one implantable antenna configured to receive the first transmission signal from the first external device; an implantable receiver; at least one implantable functional element configured to interface with the patient; an implantable controller; an implantable energy storage assembly; and an implantable housing surrounding at least the implantable controller and the implantable receiver. Medical apparatus are also provided.

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 system for restoring muscle function to the lumbar spine to treat low back pain is provided. The system may include electrodes coupled to an implantable pulse generator (IPG), a handheld activator configured to transfer a stimulation command to the IPG, and an external programmer configured to transfer programming data to the IPG. The stimulation command directs the programmable controller to stimulate the tissue in accordance with the programming data. The system may include a software-based programming system run on a computer such that the treating physician may program and adjust stimulation parameters.

An implantable head-mounted unibody peripheral neurostimulation system is provided for implantation in the head for the purpose of treating chronic head pain, including migraine. The system may include an implantable pulse generator (IPG) from which multiple stimulating leads may extend sufficient to allow for adequate stimulation over multiple regions of the head, preferably including the frontal, parietal and occipital regions. A lead may include an extended body, along which may be disposed a plurality of surface metal electrodes, which may be sub-divided into a plurality of electrode arrays. A plurality of internal metal wires may run a portion of its length and connect the IPG's internal circuit to the surface metal electrodes. The IPG may include a rechargeable battery, an antenna, and an application specific integrated circuit. The IPG may be capable of functional connection with an external radiofrequency unit for purposes that may include recharging, diagnostic evaluation, and programming.

A transcutaneous energy transfer system (TETS) that includes external and internal coils that have permeable cores is provided. According to one aspect, the TETS includes an external coil having disposed in proximity thereto, a first set of at least one permeable core that is wound by windings of the external coil. The TETS also includes an internal coil having disposed in proximity thereto, for each permeable core disposed in proximity to the external coil, a corresponding permeable core that is wound by windings of the internal coil.

A cochlear implant including a stimulation assembly including an antenna and a stimulation processor and a cochlear lead, operably connected to the stimulation processor, including an electrode array with a flexible body, a plurality of electrically conductive contacts on the flexible body, and a high contrast orientation indicator on a portion of the cochlear lead proximal of the electrode array.
