Area of Science:

  • Biomedical Engineering
  • Medical Device Technology
  • Drug Delivery Systems

Background:

  • Implantable drug infusion pumps are widely used clinically.
  • Methods for diagnosing suspected pump failures are needed.
  • Previous benchtop apparatus was cumbersome for in vivo monitoring.

Purpose of the Study:

  • To develop a portable apparatus for diagnosing implantable drug infusion pump failures.
  • To provide a simpler and more accessible method for in vivo pump monitoring.

Main Methods:

  • A portable interrogation unit was created, comprising a laptop computer, data acquisition software, an analog/ASCII interface, a pressure transducer, and fluid conduits.
  • Communication with the implanted pump is achieved via percutaneous needle puncture of the drug reservoir refill septum.

Related Experiment Videos

  • Pump performance is assessed by incrementally filling the reservoir and simultaneously measuring reservoir pressure.

    • Main Results:

    • The apparatus generates a real-time plot of pressure versus volume.
    • This pressure-volume plot quickly identifies or rules out reservoir pressure as a failure mode.
    • Diagnostic runs are saved for archival purposes.

    Conclusions:

    • The portable pump interrogation apparatus offers a practical solution for diagnosing implantable drug infusion pump failures.
    • This device is expected to be as beneficial as the previously developed benchtop apparatus for pump technology development and clinical use.
