Abstract: The production method of the present invention can reuse a non-impregnated catalyzed sol, which has been typically discarded, by recovering the catalyzed sol, which is not impregnated in impregnating of a catalyzed sol into a blanket base, to stop gelating the catalyzed sol, and then using this in subsequently preparing a catalyzed sol.

Abstract: An apparatus is provided for remotely powering an implantable medical device (IMD) positioned at a target treatment location within a patient. The apparatus is configured to be positioned at or near an external skin surface of the patient in proximity to the target treatment location. The apparatus includes an induction coil which, when placed in proximity to the IMD, forms an inductive transcutaneous power link with the IMD such that when the induction coil is supplied with a current, the induction coil inductively and transcutaneously delivers power to the IMD. An aerogel layer is disposed between the induction coil and the patient's skin surface. The aerogel layer is configured to receive heat generated from the induction coil and regulate heat dissipation from the aerogel layer to minimize heat transfer to the patient.
