Method and system for monitoring and treating hemodynamic parameters
A multiplexed medical carrier provides for sensing one or more patient parameters and/or delivering energy via separately identifiable effectors. The carrier includes a body and at least two electrical conductors coupled with at least two effectors. Effectors may be any combination of sensors, actuators or both. Sensors may measure such parameters as pressure, oxygen content, volume, conductivity, fluid flow rate, or any other chemical or physical parameters. Actuators may be used, for example, to pace a heart, stimulate muscle or neural tissue, broadcast ultrasonic energy, emit light, heat or other forms of radiation, or deliver any form of energy or substance. A method for collecting medical data from a patient includes interrogating a network of multiplexed sensors residing on parallel conductors in the patient, including addressing a first addressable sensor in the network to obtain data and addressing a second addressable sensor in the network to obtain data.
1. A method for configuring a medical carrier having a body and at least two conductors, wherein the method comprises the steps of:
providing separately identifiable effectors, wherein the effectors are axially spaced apart along the length of the carrier's body and wherein at least one effector comprises:
at least two electrodes on a surface of the carrier's body; and
an identifiable microprocessor capable of handling instructions, wherein the electrodes are coupled to the microprocessor and positioned about the microprocessor; and
electrically coupling each effector to the conductors through an opening defined in the surface of the carrier's body.
2. A method as in claim 1 , wherein each effector comprises:
at least one sensor coupled to the microprocessor; and
at least one actuator coupled to the mircropocessor.
3. A method for configuring a medical carrier of the type including a plurality of satellite units, wherein the method comprises:
positioning at least two separately identifiable effectors along an elongate body, wherein each effector comprises:
a microprocessor capable of handling instructions; and
a plurality of electrodes that are positioned about the microprocessor and electrically coupled to the microprocessor and controlled thereby;
electrically coupling the microprocessor of each effector to a pair of shared conductors running the length of the elongated body, wherein the shared conductors carry power and data; and
configuring each effector through instructions provided to its corresponding microprocessor using one conductor of the pair of shared conductors.
