1. An implantable medical sensor for remotely sensing and measuring a parameter within a patient'"'"'s body, the sensor comprising:

  • a housing having a proximal end and a distal end and having a longitudinal axis and a deformable membrane fixed to one end of the housing, the membrane being deformably movable in direct correspondence to a change in a measured parameter within the patient'"'"'s body;

    a microchip positioned within the housing and operatively communicating with the membrane for transmitting a signal indicative of the parameter, wherein the signal is a digital signal, the microchip comprising an array of photoelectric cells;

    an LED for transmitting light at the photoelectric cells;

    a shutter connected to the membrane and moveable between the photoelectric cells and the LED in response to deforming of the membrane;

    a first set of anchoring members operatively connected to the proximal end of the housing; and

    a second set of anchoring members operatively connected to the distal end of the housing;

    the first set of anchoring members and the second set of anchoring members being movable between a collapsed position and a deployed position, the collapsed position being defined as a position whereby the first set of anchoring members and the second set of anchoring members are substantially parallel to the longitudinal axis of the housing and the deployed position being defined as a position whereby the first set of anchoring members and the second set of anchoring members are substantially perpendicular to the longitudinal axis of the housing, and wherein each anchoring member of the first set of anchoring members and the second set of anchoring members comprise a ring member, each ring member having a tissue engaging surface thereon.
