<p>A catheter sensor assembly comprises: a) an elongate member (11) with a distal end (12) to ease insertion of the catheter sensor assembly (16) and a proximal extension (13) shaped for fitment of the member into a lumen (20) of a catheter tube (30), the distal end (12) and the proximal extension (13) joined by an intermediate part (14); b) a lower section (36) having a curved bottom (37) defining the tubular shape of the elongate member (11) so that when the proximal extension (13) is fit within the lumen (20) the tubular member extends distally therefrom; c) a passage (15) opened in a first direction and extending along the proximal extension and across the intermediate part; d) a sensor (16) carried upon and overlying the passage intermediate part near the distal end, the sensor having a bottom surface (17) of substantially planar configuration and a top (18) with an open recess (38) so that the top recess faces in the first direction when the sensor covers the passage with the bottom planar surface in communication with a distal portion of the passage and the lumen (20); e) conductors (25) attached to an area of the sensor bottom planar surface near the proximal extension for transmitting signals from the sensor (16) through the lumen; and f) an adhesive sealant (27, 28) between the sensor and the intermediate part about the bottom planar surface for securing the sensor to the member on the intermediate part near the distal end with the sealant also across the conductors and the area of the sensor that the sealant does not close the entire passage.
