    摘要： A balloon catheter comprises a balloon, an inner shaft, an outer shaft and a transition shaft. The transition shaft has a proximal portion and a distal portion joined by a tapered portion. The proximal portion has a diameter greater than the distal portion. The proximal portion has a first end portion engaged to at least a portion of the outer shaft at a first engagement site. At least a portion of the proximal waist is engaged to the proximal portion of the transition shaft at a second engagement site. At least a portion of the end region of the inner shaft is engaged to the distal portion of the transition shaft at a third engagement site. The distal portion extends through the balloon wherein at least a portion of the distal waist of the balloon is engaged to the distal portion of the transition shaft at a forth engagement site.

    摘要： There is provided a method of monitoring one or more specified reactions in a fluid medium sample using a thermal signature, comprising providing at least one micro-cantilever sensor, said micro-cantilever sensor comprising at least two materials having different coefficients of thermal expansion, and having a heater and piezo-resistive sensor integrated therein, calibrating the at least one micro-cantilever response to thermal changes to form a calibrated micro-cantilever response characteristic, starting the specified reaction in the fluid medium sample, pulsing the heater with one or more electrical pulses to induce heat generation in the micro-cantilever, sampling the output of the integrated piezo-resistive sensor to characterize a response of the micro-cantilever during the specified reaction in the fluid medium, and subtracting the calibrated micro-cantilever response characteristic from the sampled output to determine a characteristic of the one or more specified reactions in the fluid medium sample. There is also provided a method for measuring at least one thermal property of a fluid medium sample, and a fluid medium sample reaction detection apparatus.
