  • Publication number: 20080319371
    Abstract: A method to electrokinetically deliver a medicament to a nail of a mammalian user including: forming a cast of the nail of the user wherein the cast is a reverse impression of the nail; applying a medicament matrix to the nail; sandwiching the medicament matrix between the cast and the nail; pressing the medicament matrix to the nail using the cast; applying electrical current to an electrical current path extending through the medicament matrix and the nail, and delivering medicament from the matrix into the nail by electrokinetic transporting the medicament along the current path.

  • Publication number: 20080262414
    Abstract: An applicator cartridge for use with a device for electrokinetically delivering a medicament to a treatment site, the cartridge including: an applicator head including an active electrode, and a conductive path extending between a pair of electrical contacts, wherein the electrical contacts electrically engage respective contacts on the device when the cartridge is inserted into the device; a matrix support surface of said applicator head adjacent the active electrode; a matrix attached to the matrix support surface and in contact with the active electrode, the matrix having an exposed surface adapted to be applied to the treatment site; a medicament or a medicament and an electrically conductive carrier carried by said matrix; a removable lid covering the exposed surface of the matrix and sealed to the applicator head, the lid is conductively coupled to the applicator head and completes the conductive path on the applicator head, wherein removal of the lid breaks the conductive path.

  • Patent number: 5107833
    Abstract: A software-controlled, external programmer for transcutaneously programming and receiving data from an implanted medical device providing a real-time indication of the implanted medical device RF telemetry signal strength to the user of the device programmer while automatically optimizing gain level to minimize interference in the presence of noise. The method and apparatus involves monitoring the validity of received intervals or frames uplinked from the implanted medical device to adjust the gain of the RF amplifier in a pre-determined range. When noise is detected, indicating a relatively small signal-to-noise ratio, the automatic gain control (AGC) level is decreased, effectively tracking this condition. Similarly, lack of any signal of loss of individual RF pulses causes the AGC level to be increased.
