Tigertriever 25 Revascularization Device
Product: Tigertriever 25 Revascularization Device — all models and sizes · Where to buy
FDA Clearance Information
FDA-Cleared Indications
- The device is indicated for the removal of thrombus from the neurovasculature in patients experiencing ischemic stroke.
- It is intended for use in patients who are eligible for mechanical thrombectomy according to the device labeling and applicable clinical guidelines.
- The device is intended for use by trained physicians with appropriate imaging and endovascular equipment.
Clinical Applications
- Mechanical thrombectomy for selected acute ischemic strokes caused by a clot in a brain artery.
- Endovascular removal of thrombus from the intracranial neurovasculature.
- Use during catheter-based stroke treatment when vascular imaging identifies a removable arterial occlusion.
- Clot retrieval through a neurovascular catheter system under fluoroscopic guidance.
Reported off-label uses
- Use in selected occlusions or vascular territories outside the device's specific FDA labeling may be reported in clinical practice, but this is off-label and should be determined by the treating specialist.
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 device is delivered through a compatible neurovascular catheter and is selected according to the target vessel, clot location, anatomy and access route.
- Treatment generally requires arterial access, often through the common femoral or radial artery, with fluoroscopic and cerebral angiographic guidance.
- Procedures may be performed with conscious sedation or general anesthesia, depending on the patient's condition and institutional practice.
- MRI safety and scan conditions should be confirmed in the current manufacturer labeling before MRI is performed; the device is intended for temporary use and is removed during the procedure.
- Contraindications, vessel-size requirements, catheter compatibility and handling instructions must be checked in the current FDA-cleared instructions for use.

Frequently Asked Questions
What is the Tigertriever 25 used for?
It is used to remove a blood clot from a brain artery during mechanical thrombectomy for selected acute ischemic strokes.
Is the Tigertriever 25 MRI safe?
MRI safety depends on the device's current labeling and whether the device remains in the body. It is normally removed after clot retrieval, and the manufacturer's MRI conditions should be reviewed before scanning.
What sizes are available for the Tigertriever 25?
The Tigertriever 25 is a 25-size neurovascular revascularization device, with device length and configuration options determined by the current product labeling. Physicians select the appropriate size for the target vessel and clot.
How long does the Tigertriever 25 last?
It is a temporary device used during a single thrombectomy procedure and is removed after clot retrieval. It is not intended to remain permanently implanted.
How much does the Tigertriever 25 cost?
The device price and total stroke-thrombectomy cost vary by hospital, location, insurance coverage, physician fees, anesthesia and other procedural services. Patients should ask the treating hospital and insurer for an individualized estimate.
