An external charging system for an Implantable Medical Device (IMD) is disclosed having a thermal diffuser proximate to the primary charging coil for distributing heat from the primary charging coil. In an example, the primary charging coil is mounted to a first side of a circuit board, and the thermal diffuser is also connected to the first side and in contact with the primary charging coil. In one example, the thermal diffuser is a plastic material, such as an acrylic pad, with a high thermal conductivity and a low electrical conductivity. The thermal diffuser may also contact temperature sensors mounted to the first side of the circuit board.

A rechargeable battery installed in a battery powered device is charged using a separate battery charging device. A charging signal is provided from the battery charging device to the battery powered device. The charging signal includes energy to charge the battery during a charging session. In the battery charging device from the battery powered device, a plurality of values of a charging parameter is received. The values reflect an amount of energy being received by the battery powered device from the charging signal provided by the battery charging device. In the battery charging device, the plurality of values of the charging parameter received from the battery powered device are analyzed. In the battery charging device, the charging signal is adjusted based on the analyzing.

An intraocular implant (IOI) includes a lens structure with variable optical power, a sensor that detects an optical accommodation response, a rechargeable power storage device, a recharging interface, a wireless communication interface, and a controller. The controller can receive information from the sensor indicating an optical accommodation response, control the lens structure to vary the variable optical power based on the information received from the sensor, control the recharging interface to recharge the rechargeable power storage device, and further control the recharging interface to receive power for operation of the IOI, and transmit and receive information through the wireless communication interface.

Electrical energy is transcutaneously transmitted at a plurality of different frequencies to an implanted medical device. The magnitude of the transmitted electrical energy respectively measured at the plurality of frequencies. One of the frequencies is selected based on the measured magnitude of the electrical energy (e.g., the frequency at which the measured magnitude of the electrical energy is the greatest). A depth level at which the medical device is implanted within the patient is determined based on the selected frequency. For example, the depth level may be determined to be relatively shallow if the selected frequency is relatively high, and relatively deep if the selected frequency is relative low. A charge strength threshold at which a charge strength indicator generates a user-discernible signal can then be set based on the determined depth level.

A system and method for using statistical analysis of information obtained during a rechargeable battery charging session, wherein the method is for optimizing one or more parameters that are used for controlling the charging of a rechargeable battery during the charging session.

An external charger for a battery in an implantable medical device and charging techniques are disclosed. Simulation data is used to model the power dissipation of the charging circuitry in the implant at varying levels of implant power. A power dissipation limit constrains the charging circuitry from producing an inordinate amount of heat to the tissue surrounding the implant, and duty cycles of a charging field are determined so as not to exceed that limit. A maximum simulated average battery current determines the optimal (i.e., quickest) battery charging current, and at least an optimal value for a parameter indicative of that current is determined and stored in the external charger. During charging, the actual value for that parameter is determined, and the intensity and/or duty cycle of the charging field are adjusted to ensure that charging is as fast as possible, while still not exceeding the power dissipation limit.
