1. A method for determining blood pressure of an artery, the method comprising:
- applying pressure to the artery so that the artery exhibits a plurality of pressure waveforms representing pulses in the artery;
producing sensed pressure waveform data representing each of the plurality of pressure waveforms;
deriving a plurality of parameters related to waveform shape from the sensed pressure waveform data for a selected one of the waveforms, including at least one parameter other than maximum pressure waveform amplitude and applied pressure corresponding to the maximum pressure waveform amplitude; and
determining a blood pressure value based upon the parameters.

Abstract
The present invention is a method for calculating blood pressure of an artery having a pulse. The method includes applying a varying pressure to the artery. Pressure waveforms are sensed to produce pressure waveform data. Waveform parameters are derived from the sensed pressure waveform data. Blood pressure is then determined using the derived parameters.
