Abstract
A method for telemetrically measuring a parameter in a patient's heart comprises the steps of imaging the heart and identifying an implantation site in the heart. An opening is created in the tissue at the implantation site. A sensor comprising a housing, a membrane at one end of the housing wherein the membrane is deformable in response to the parameter, and a microchip positioned within the housing and operatively communicating with the membrane for transmitting a signal indicative of the parameter is provided. The sensor is placed in the opening and the parameter is telemetrically measured from outside of the patient's body based on the transmitted signal by the sensor. The sensor is also telemetrically powered from outside of the patient's body. A signal charging and reading device is placed outside of the patient's body for telemetric powering and signal reading with respect to the sensor. In an alternative embodiment, the sensor has a tapered distal end and a tissue piercing tip for direct implantation into tissue. Alternative embodiments of this sensor include helical threads on the tapered distal end for threading the sensor into tissue and a plurality of tissue barbs for direct and firm anchoring of the sensor in tissue.
