ABSTRACT:
Measurement devices and methods for measuring balloon catheters are provided. Embodiments enable measuring the outer dimensions and burst pressure of a balloon catheter. The measurement apparatus can measure a balloon catheter in ambient air or a balloon catheter submerged in a heated water bath. In ambient air, an axial drive mechanism translates the balloon catheter in an axial direction and a rotary drive mechanism rotates the balloon catheter while a measurement device is used to measure balloon catheter dimensions. In a water tank, an axial drive mechanism translates the balloon catheter in an axial direction while a measurement device is used to measure the burst pressure of the balloon catheter. The devices and methods can utilize a laser micrometer in order to provide such measurements. A control unit provides a user interface and is capable of displaying real time data during the measurement process.
