TCAR®. A growing history
of clinical evidence

Driven by Consistently Low Stroke Rates


The growing body of evidence continues to validate and strengthen TCAR’s clinical story as a safe and reproducible alternative to CEA.

The Less Invasive Standard in Stroke Prevention.


Along with the stroke protection provided by TCAR, the less invasive approach
has a multitude of additional patient, physician and hospital benefits.

Benefits of a Less Invasive Approach

With a less invasive approach than CEA, a number of significant patient benefits are realized. These lead to improved patient outcomes and reductions in adverse events. Cranial nerve injury is the most common neurologic complication of CEA. Rates of cranial nerve injury range from 5.1% to 8.6%6 in clinical trials. With a smaller incision compared to CEA, scarring and rates of cranial nerve injury are significantly reduced with TCAR.

Procedural Efficiencies

There are many efficiencies that can translate to benefits to the patient, physician and hospital. The TCAR procedure significantly reduces clamp time and overall procedure time compared to a more invasive surgical procedure (CEA).

Evidence for TCAR as a safe, less invasive
alternative to CEA.

With a growing list of trials and clinical results, TCAR has built an indisputable library of proof of efficacy in stroke protection and positive patient outcomes. Click below to learn more about some of the studies that make up the large and growing body of evidence supporting TCAR as safe and effective for patients with carotid disease.

transcervical access and cerebral
embolic protection system.

Pivotal results in a prospective, single-arm,
multi-center trial of TCAR in high surgical
risk patients.

The TSP looks at real-world outcomes of all patients captured in the Vascular Quality Initiative (VQI).

The TCAR vs. TF-CAS Study reviewed patient data collected from the VQI-TSP to compare outcomes of TCAR vs TF-CAS.
