What It Is

The Innerdyne Radially Expanding Vascular Access System is designed to provide a stable and reliable means of accessing the vascular system. It features a heparin coating to reduce the risk of thrombosis and improve biocompatibility. The radial expansion mechanism allows for minimal trauma during insertion, making it suitable for delicate vascular procedures.

FDA-Cleared Indications

  • Vascular access for the introduction of catheters and other vascular instruments.
  • Use in procedures requiring access to the vascular system, including catheter-based embolization procedures.

Clinical Applications

  • Obtaining vascular access for catheter-based embolization procedures.
  • Providing access for placement or manipulation of intravascular catheters and other instruments.
  • Supporting minimally invasive vascular procedures in which a stable access route is needed.

Reported off-label uses

  • Use as an access route for other endovascular interventions when selected by the treating clinician based on device compatibility and patient anatomy.

Off-label use: these uses are reported in practice or the literature but are not part of the FDA-cleared indications. Physicians may use a cleared device off-label based on their medical judgment; the manufacturer may not promote off-label uses.

Practical Considerations

  • Select the device size and configuration to match the access vessel, patient anatomy, and instruments being used.
  • Confirm compatibility with the guidewires, catheters, sheaths, and other equipment planned for the procedure.
  • The heparin coating does not eliminate the risk of thrombosis, bleeding, infection, arterial injury, or other vascular-access complications.
  • Use imaging guidance and appropriate sterile technique; follow the current manufacturer instructions for preparation, insertion, removal, and disposal.
  • MRI safety information should be confirmed in the current device labeling. Do not assume the device is MR safe or MR conditional without that documentation.

Related Literature

The linked study explored the development of a percutaneous fetoscopic access system for tracheal occlusion in congenital diaphragmatic hernia. It demonstrated the feasibility of using a radial expansion sheath for safe access in an ovine model. The study highlighted the potential for reducing maternal morbidity by avoiding laparotomy, though it was limited by its animal model and early-stage development.
