Testing Catheters in Real-World Conditions

Manufacturers of catheters usually test their products by simulating real-world conditions. The simulation includes replication of a patient lying in an operating room and a surgeon inserting a catheter. ZwickRoell developed a horizontal testing machine in close cooperation with customers and surgeons. The machine has a number of special adaptations to enable the simulated operational procedure on the patient.

Over the years, ZwickRoell has expanded its portfolio and now offers a variety of testing solutions connected to design, testing, and production challenges faced by catheter manufacturers today.

Solutions

The solutions offered by ZwickRoell vary from a horizontal Allround with or without water bath to a horizontal zwickiLine, and can determine numerous results, such as:

  • Track force - the force needed to advance a catheter, interventional device or guide wire through a tortuous path is measured
  • Push efficiency - the amount of force that is experienced by the distal tip of the product when a known force is being applied to the product on the proximal end is measured by the proximal and distal load cell
  • Insertion force measurement - measures the force used to advance through the introducer sheath
  • Guide-wire movement – provides measurement of the force needed to advance a guide wire through catheter, guide catheter or other interventional device
  • Flexibility - measures ability of the tip of the catheter to track over a specified bend in a guide wire, i.e. 90 degrees
  • Guide wire and catheter lubricity track measurement - comparative test which uses the track test data in order to determine if coatings have an effect on the force required to advance product through a tortuous path
