System, apparatus and method for interacting with a targeted tissue of a patient

摘要

A method and an apparatus are provided for interacting with targeted tissue of a patient. The apparatus comprises a central control module, a satellite module, and a lead. The satellite module comprises a processor, a communication module, a switching module, a memory, a sense amp, and a A/D converter. The apparatus is adapted for subcutaneous implantation. The central control module is coupled to the satellite module. The lead is coupled to the satellite module. A programming word comprising information to be sent to the satellite module is provided. The programming word is converted into identifiable groups of pulses corresponding to bits of the programming word. The identifiable groups of pulses are sent to the satellite module. The identifiable groups of pulses are converted to information for providing a therapy to the patient. The energy from the identifiable groups of pulses is stored to power the satellite module.

1. An implantable medical system for use in conjunction with a remote programmer and a power source, the implantable medical system comprising:
a central control module, comprising:
a housing configured to support the power source; anda wireless receiver disposed in the housing, the wireless receiver configured to be coupled to the power source and to receive programming signals from the remote programmer; an elongated conductor comprising at least one connector and having a distal end portion and a proximal end portion, the proximal end portion coupled to the central control module, the elongated conductor carrying power from the power source and digital communications including the programming signals from the wireless receiver, the power and the digital communications being combined on the at least one connector; a plurality of leads; a plurality of tissue-interactive elements associated with the plurality of leads; and a satellite control module coupled between the plurality of leads and the distal end portion of the elongated conductor, the satellite control module comprising a housing such that at least a portion of the plurality of leads and the plurality of tissue-interactive elements are external of the housing of the satellite control module, the satellite control module being configured to utilize the power received through the elongated conductor to generate and selectively route electrical signals to selected ones of the plurality of tissue-interactive elements through the plurality of leads in accordance with the programming signals received from the remote programmer through the elongated conductor by the programming signals including separate values with each value of the separate values corresponding to a tissue-interactive element of the plurality of tissue-interactive elements and with each value of the separate values representing a state of the corresponding tissue-interactive element where the value specifies one of at least three available states for the corresponding tissue-interactive element.
