  • Sensor to detect changes in the cross section of an elongated body cavity
    Patent number: 6083179
    Abstract: A medical apparatus (1) for detecting changes in the cross section of an elongate body cavity, for example, a human urinary tract. The apparatus includes a retainer portion (60) and a sensor portion (10) connected to the retainer portion and having a sensitive body (30) of flexible material. The sensor portion has a first end portion which is fixed to the retainer device (60). The sensitive body is designed as a catheter-like device projecting from the retainer portion (60) and provided at its free end (17) with a rigid closure (37). The sensitive body is hollow and its cavity varies according to the compression of the sensitive body due to cross-sectional changes of the elongated body being examined. A pressure-sensing device indicates the pressure in the cavity and thus the cross sectional changes of the elongated body.
