Ultraflex Ev Hemostasis Introducer
FDA Clearance Information
The Ultraflex EV Hemostasis Introducer was cleared through the FDA 510(k) pathway on September 25, 2001. Manufactured by St Jude Medical, it is classified as a Class 2 device under product code DYB.
What It Is
FDA-Cleared Indications
- Introduction and delivery of embolization coils during vascular procedures.
- Vascular access for procedures requiring placement of embolic coils to occlude or control blood flow.
Clinical Applications
- Delivery of embolization coils for treatment of selected aneurysms and pseudoaneurysms.
- Delivery of embolization coils to control bleeding from selected gastrointestinal or other vascular sources.
- Coil embolization of selected arteriovenous malformations or abnormal vascular connections.
- Coil occlusion of selected visceral, pelvic, or peripheral vessels when vascular embolization is indicated.
Reported off-label uses
- Use as an access sheath for delivery of other embolic materials or vascular devices when compatible with the catheter system and procedural technique.
- Use in selected venous embolization procedures, such as varicocele or ovarian-vein embolization, when the device size and configuration are appropriate.
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
- The appropriate sheath size and length must be selected for the target vessel, access site, guidewire, delivery catheter, and embolization coil system.
- The device is used with fluoroscopic or other appropriate imaging guidance by clinicians trained in vascular access and embolization.
- Check compatibility with the intended catheter, guidewire, and coil system before use; do not force the device if resistance is encountered.
- Potential complications include bleeding, hematoma, arterial or venous injury, thrombosis, infection, vasospasm, embolization to an unintended location, and contrast-related complications.
- MRI safety and conditional use should be confirmed in the current manufacturer labeling. The FDA record alone does not establish that the device is MR Safe or MR Conditional.
