A novel remote-controlled vascular occluder, adapted from stereotactic biopsy forceps, offers precise temporary arterial blood flow control. This innovative device provides surgeons with immediate on-off occlusion capabilities, enhancing procedural safety and efficacy in complex vascular interventions.

Area of Science:

  • Biomedical Engineering
  • Neurosurgery
  • Vascular Surgery

Background:

  • Temporary control of arterial blood flow is crucial in various surgical procedures.
  • Existing methods for vascular occlusion may have limitations in precision or accessibility.
  • The need for adaptable tools in complex surgical fields, such as neurosurgery, is significant.

Purpose of the Study:

  • To introduce a new remote-controlled vascular occluder designed for temporary arterial occlusion.
  • To describe the design modifications and functional capabilities of the novel occluder.
  • To highlight the device's utility in challenging surgical scenarios and specific vascular pathologies.

Main Methods:

  • Modification of existing stereotactic biopsy forceps to create the vascular occluder.
