What It Is
FDA-Cleared Indications
- Dilation of stenotic or obstructed blood vessels during percutaneous transluminal angioplasty.
- Use in peripheral vascular angioplasty procedures to improve blood-vessel lumen diameter and blood flow.
Clinical Applications
- Balloon angioplasty of narrowed peripheral arteries.
- Dilation of obstructed or stenotic veins when percutaneous transluminal angioplasty is indicated.
- Treatment of vascular narrowing associated with atherosclerotic or other obstructive vascular disease.
- Use during image-guided endovascular procedures in which controlled balloon dilation of a blood vessel is required.
Reported off-label uses
- Balloon dilation of selected vascular stenoses outside the specific anatomy or indications described in the device labeling may occur in clinical practice, but this is off-label and should be determined by the treating physician.
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
- Available catheter and balloon dimensions must match the target vessel diameter, lesion length, access route and guidewire or sheath requirements.
- The balloon should be inflated gradually with the recommended contrast-saline mixture and pressure limits; excessive pressure or oversizing can injure the vessel.
- The catheter is used with fluoroscopic or other appropriate imaging guidance and standard angioplasty equipment.
- MRI safety depends on the exact catheter model and whether it remains in the patient; consult the current product labeling before MRI. A temporary catheter is generally removed after the procedure.
- Contraindications and precautions include inability to safely cross the lesion, significant vessel injury or dissection, uncorrected bleeding risk, and allergy or kidney-related concerns involving contrast media.
