Cardiac stimulation control and communication system
First Claim
1. A cardiac system comprising:
- a processor for receiving and processing input signals, received from one or more electrodes, into processed signals, said electrodes are adapted to be placed in a heart;
a signal processing network for receiving said processed signals and for providing from said processed signals a first Time Division Multiple Access (TDMA) signal and a second filtered Code Division Multiple Access (CDMA) signal to a selector, wherein said first and second signal are different signals; and
a selector for selecting said TDMA or said filtered CDMA signal and providing said selected TDMA or CDMA signal to a modulator and transmitter for modulation and wireless transmission of said selected signal by said modulator and said transmitter.

Abstract
Cardiac stimulation control and communication system, including a pacemaker, having a processor for processing input signals to and/or from one or more electrodes located in a heart. A signal processing network for receiving input signals and for providing a Time Division Multiple Access (TDMA), a filtered signal, spread spectrum signal and/or Orthogonal Frequency Division Multiplex (OFDM) signal to a selector for selection and transmission. In-phase and quadrature-phase cross-correlated spread spectrum signals are provided to a modulator for modulation and transmission of signals received from one or more electrodes or probes or sensors used by a patient. An implantable cardiac stimulation device and a telemetry transmitter and telemetry wired or wireless receiver, for transmission and reception of wireless and or wired signals, wherein said telemetry signals are for monitoring and/or controlling the implantable cardiac stimulation device. A pacemaker, receiver and demodulator for receiving and demodulating a Global Positioning System (GPS) receiver for receiving location finder signals or a receiver and demodulator for receiving and demodulating other than GPS signals and for providing location finder signals and for connecting said location finder signals to a transmitter for transmitting said location finder signals. A Time Division Multiple Access (TDMA) signal is provided to a non-quadrature modulator for non-quadrature modulation of TDMA signal and a filtered signal is processed into a cross-correlated spread spectrum in-phase and quadrature-phase filtered signal and provided to a quadrature modulator for quadrature modulation of said cross-correlated spread spectrum filtered signal. The transmitted signals are received and used by a nurse or other health professionals.
