    摘要: Improved apparatus and methods for non-invasively assessing one or more hemodynamic parameters associated with the circulatory system of a living organism. In one aspect, the invention comprises apparatus adapted to accurately place and maintain a sensor (e.g., tonometric pressure sensor) with respect to the anatomy of the subject, including an alignment apparatus which is separable from an adjustable fixture. The apparatus moveably captures the sensor to, inter alia, facilitate coupling thereof to an actuator used to position the sensor during measurements. In a second aspect, improved sensor apparatus is disclosed adapted to minimize the effects of shear during sensor movement and monitoring as well as maximize the lateral and proximal search area available to the sensor within the apparatus. Methods for positioning the alignment apparatus and sensor are also disclosed.
