A device for insertion into soft tissue including a micro electrode, a micro light source; a stiffening element having a material dissolvable or degradable in aqueous body fluid or a material swellable in such fluid to form a transparent gel; a coat of a flexible non-conducting polymer material on the stiffening element; a base disposed at the rear end of the device. The flexible coat has a distal opening allowing light emitted from the light source to leave the device upon said collapse or dissolution or swelling. Also disclosed is a therapeutic or diagnostic device formed in the tissue from the insertable device, uses thereof, and a method of disposing the insertable device in soft tissue.

An implantable medical device contains a hermetic battery. The hermetic battery contains a hermetically sealed battery housing defining an internal chamber, an electrochemical cell disposed within the internal chamber, and an electronic module disposed within the internal chamber. The electronic module is electrically conductively connected to the electrochemical cell, and the electronic module is arranged in the electrochemical cell.

Systems and methods for improved control and performance of cochlear implants are disclosed. In an embodiment, the audio environment is sampled, and a neural network determines suggested filter setting for the cochlear implant. The process is repeated such that, as the user moves through various audio environments having differing noise levels, satisfactory performance of the cochlear implant is maintained for the user.

An antenna for an implantable medical device, the antenna being configured for inductive wireless power transfer and/or near-field magnetic induction communication, the antenna comprising at least one coil or at least one set of coils, each coil comprising several windings. Furthermore, the present disclosure relates to an implantable medical device (IMD).

The types of electrode leads that are connected to an implantable medical device are determined based on electrical parameters that are measured at the electrodes that are positioned on the leads. The different types of known electrode leads have different physical electrode arrangements that impact the measured electrical parameters. Properties in the measured electrical parameters that are indicative of the physical arrangements of electrodes of known types of electrode leads are utilized to determine the types of leads that are connected to the implantable medical device.

Provided herein are systems for providing therapy to the heart of a patient. The systems include an implantable device for implantation proximate the heart of the patient. The implantable device includes: an anchoring element for maintaining the position of the implantable device after implantation in the patient, at least one sensing electrode for sensing the electrical activity of the heart, at least three pacing electrodes for delivering electrical energy to the tissue of the heart, and a controller including an algorithm for determining when the patient requires therapy. The systems further include an external device having a transceiver for transmitting energy to the implantable device.

The present invention changes the magnet-mode of an active implantable medical device (AIMD) such that repeated application of a clinical magnet in a predetermined and deliberate time sequence will induce the AIMD to enter into its designed magnet-mode. In one embodiment, a clinical magnet is applied close to and over the AIMD and removed a specified number of times within a specified timing sequence. In another embodiment, the clinical magnet is applied close to and over the AIMD and flipped a specified number of times within a specified timing sequence. This makes it highly unlikely that the magnet in a portable electronic device, children's toy, and the like can inadvertently and dangerously induce AIMD magnet-mode.

Apparatus and methods for treating back pain are provided, in which an implantable stimulator is configured to communicate with an external control system, the implantable stimulator providing a neuromuscular electrical stimulation therapy designed to cause muscle contraction to rehabilitate the muscle, restore neural drive and restore spinal stability; the implantable stimulator further including one or more of a number of additional therapeutic modalities, including a module that provides analgesic stimulation; a module that monitors muscle performance and adjusts the muscle stimulation regime; and/or a module that provides longer term pain relief by selectively and repeatedly ablating nerve fibers. In an alternative embodiment, a standalone implantable RF ablation system is described.

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.
