A novel wire-directed detachable balloon simplifies placement in arteries and veins. This new device offers easier and more accurate deployment compared to traditional flow-directed methods.

Area of Science:

  • Medical Devices
  • Vascular Interventions
  • Surgical Technology

Background:

  • Conventional detachable balloons often rely on flow-directed placement, which can be challenging for accuracy.
  • Existing methods may lack precision in targeting specific vascular locations.

Purpose of the Study:

  • To introduce and evaluate a novel wire-directed detachable balloon system.
  • To assess the ease and accuracy of placement for this new device in animal models.

Main Methods:

  • Development of a silicone detachable balloon with two self-sealing valves (proximal and distal).
  • The proximal valve secures the catheter tip; the distal valve permits guide wire passage.
  • The balloon is advanced over a guide wire, with detachment occurring after wire withdrawal.
