  • Publication number: 20240075271
    Abstract: Implantable devices and associated devices, systems, and methods are disclosed herein. The devices and systems of the present technology may be equipped with electronic components that provide a platform for remote patient and/or device monitoring. Operation of an implantable devices and/or one or more components thereof can be modulated over time depending on certain conditions. This modulation can include limiting wireless data communication with external devices to certain time intervals, varying parameters of data collection by sensing elements, and/or controlling power supplied to electronic components, for example. In some examples, an implantable device may operate in a low-power standby state in which data is obtained via sensing elements and stored in local data storage, but the data is not wirelessly transmitted to an external device until a modulation signal is received by the implantable device, causing the implantable device to change to a more active power state.

  • Publication number: 20080287944
    Abstract: A method and apparatus for carrying our thermal ablation of target tissue is disclosed. The apparatus includes an RF ablation device having a multi-electrode electrode assembly designed to be deployed in target tissue, defining a selected-volume tissue region to be ablated, and having infusion channels for infusing a liquid into the target tissue during the ablation process. A control unit in the apparatus is operably connected to an RF energy source, for controlling the RF power level supplied to the electrodes, and to an infusion device, for controlling the rate of infusion of a liquid through the device into the tissue. During both electrode deployment and tissue ablation, impedance and or temperature measurements made within the tissue are used to control the RF source and infusion device, for optimizing the time and extent of tissue ablation.
