ENROUTE® Transcarotid
Stent System

Stroke Prevention through Plaque Stabilization

First and only carotid stent system designed and indicated for transcarotid access

Designed with purpose

Designed for TCAR®, the ENROUTE Transcarotid Stent System autoconforms to anatomy and delivers long-term plaque stabilization to prevent future strokes

Features include:

  • TCAR specific delivery length: Short 57cm delivery system for ergonomic and precise stent delivery
  • Optimized cell design: Provides the most coverage of any open cell stent design, autoconforming to even the most difficult anatomies

See its effectiveness


Optimized hybrid-cell stent design autoconforms in 2mm segments for uniform scaffolding that respects native vessel anatomy.

Superb Lesion Coverage

Open cell design and autoconforming technology provide durable plaque coverage.

Instructions for use

The ENROUTE Transcarotid Stent Stystem used in conjunction with the ENROUTE Transcarotid Neuroprotection System (NPS) is indicated for the treatment of patients at high risk and standard risk for adverse events from carotid endarterectomy.

Indications for Use: The ENROUTE® Transcarotid Stent System used in conjunction with the ENROUTE Transcarotid Neuroprotection System (NPS) is indicated for the treatment of patients at high risk for adverse events from carotid endarterectomy, who require carotid revascularization and meet the criteria outlined below.

Please refer to Instructions for Use for indications, contraindications, warnings and precautions.

Caution: Federal (U.S.) law restricts this device to sale by or on the order of a physician.

Contraindications: Use of the ENROUTE Transcarotid Stent System is contraindicated in the following patients:

  1. Patients in whom antiplatelet and/or anticoagulation therapy is contraindicated.
  2. Patients in whom the ENROUTE Transcarotid NPS is unable to be placed.
  3. Patients with uncorrected bleeding disorders.
  4. Patients with known allergies to nitinol.
  5. Lesions in the ostium of the common carotid artery.

General Warnings

  1. Only physicians who have received appropriate training for transcarotid stenting and who are familiar with the principles, clinical applications, complications, side effects and hazards commonly associated with carotid interventional procedures should use this device.
  2. The safety and efficacy of the ENROUTE Transcarotid Stent System have not been demonstrated with embolic protection systems other than the ENROUTE Transcarotid NPS. Use the ENROUTE Transcarotid Stent System only with the ENROUTE Transcarotid NPS.
  3. The long term performance (> 3 years) of carotid stents has not yet been established.
  4. As with any type of vascular implant, infection secondary to contamination of the stent may lead to thrombosis, pseudoaneurysm or rupture.
  5. The stent may cause a thrombus, distal embolization or may migrate from the site of implant through the arterial lumen. Appropriate sizing of the stent to the vessel is required to reduce the
    possibility of stent migration (see Section 9.3 of the full instructions for use). In the event of thrombosis of the expanded stent, thrombolysis and PTA should be attempted.
  6. Overstretching of the artery may result in rupture and life-threatening bleeding.
  7. In patients requiring the use of antacids and/or H2-antagonists before or immediately after stent placement, oral absorption of antiplatelet agents (e.g., aspirin) may be adversely affected.
  8. The appropriate antiplatelet and anticoagulation therapy should be administered pre- and post-procedure as suggested in Section 9.1 of the full instructions for use.
  9. In the event of complications such as infection, pseudoaneurysm or fistulization, surgical removal of the stent may be required.
    Non-clinical testing has demonstrated that the ENROUTE Transcarotid Stent is MR Conditional.
