Area of Science:

  • Biomedical Engineering
  • Medical Devices
  • Cardiovascular Research

Background:

  • The development of advanced medical devices is crucial for improving patient outcomes.
  • Existing imported PIAB catheters present a benchmark for hemodynamic performance.
  • Cost-effectiveness remains a significant consideration in healthcare technology adoption.

Purpose of the Study:

  • To evaluate the hemodynamic effects of a newly designed PIAB catheter.
  • To compare the performance of the laboratory-developed PIAB catheter against imported products.
  • To assess the clinical and economic viability of the novel PIAB catheter.

Main Methods:

  • Serial animal experiments were conducted using goats to assess hemodynamic parameters.
  • Comparative analysis was performed between the PIAB catheter and imported devices.

  • Clinical usage data from hospitals was collected to evaluate real-world performance.

    • Main Results:

    • Hemodynamic parameters such as BAPDP (24) vs PSP (22), BAEDP (8) vs EDP (14), and BAPSP (20) vs PSP (22) were recorded.
    • The PIAB catheter exhibited hemodynamic performance equivalent to or exceeding that of imported products.
    • The PIAB catheter is significantly more affordable than foreign-manufactured alternatives.

    Conclusions:

    • The PIAB catheter developed in our laboratory presents a cost-effective and high-performing alternative to imported devices.
    • The device has demonstrated satisfactory results in initial hospital implementations.
    • Further adoption of this PIAB catheter could lead to significant cost savings in healthcare.
