Area of Science:

  • Vascular surgery
  • Medical device innovation
  • Interventional radiology

Background:

  • Foreign body retrieval in small vessels poses significant challenges.
  • Existing devices may have limitations in accessing or effectively removing embolic materials and iatrogenic fragments.
  • Minimally invasive retrieval techniques are crucial for reducing patient morbidity.

Purpose of the Study:

  • To evaluate the efficacy and safety of a new retrieval device designed for small vessel applications.
  • To assess the device's performance in retrieving various types of foreign bodies from a range of arterial locations.
  • To determine the feasibility of selective placement in challenging anatomical areas.

Main Methods:

  • A canine model was utilized to simulate clinical scenarios.

  • Retrieval attempts were performed on 25 embolic coils, 3 silicone balloons, and 5 catheter/guide wire fragments.
  • The device was tested in multiple arteries including renal, pulmonary, hepatic, brachiocephalic, subclavian, carotid, and maxillary.
  • Selective placement in vertebral and proximal basilar arteries was also assessed.

    • Main Results:

    • The retrieval device achieved a high success rate of 91% (30 out of 33 attempts).
    • Successful retrieval was demonstrated across a variety of embolic materials and vessel types.
    • The device showed selective placement capability in deep and tortuous vessels like the vertebral and basilar arteries.

    Conclusions:

    • The new retrieval device is highly effective for removing foreign bodies from small and critical arteries.
    • Its high success rate and selective placement capability make it a promising tool for interventional procedures.
    • This device potentially offers a safer and more efficient option for managing retained materials in vascular interventions.
