Initial Clinical Experience With the Micromesh Roadsaver Carotid Artery Stent for the Treatment of Patients With Symptomatic Carotid Artery Disease

Abstract

The Roadsaver double layer micromesh stent seems to be safe and effective in the treatment of extracranial ICA stenosis and in the context of tandem lesions in ischemic stroke. Further studies with larger populations are warranted.

Incidence of New Ischaemic Brain Lesions After Carotid Artery Stenting with the Micromesh Roadsaver Carotid Artery Stent: A Prospective Single-Centre Study

“…Preliminary results with CGuard, a novel meshcovered carotid stent, have been published [9]. The safety and the efficacy of Roadsaver, a nitinol dual-layer micromesh stent designed to contain plaque against the vessel wall preventing its protrusion and release of emboli after deployment, were satisfactorily tested by Hopf-Jensen et al [10].…”

Commentary: Carotid Artery Revascularization for Stroke Prevention

“…51,52 With low-risk, safe, and durable CAS, we may at last be able to get away from the paradox of CAS revascularization ("too late" if the patient has already developed stroke vs "indication uncertain" and "intervention risk exceeding that associated with the disease's natural history" in some asymptomatic cohorts). Access to safe CAS 11,13,61,62,64 is particularly important in weighing the peri-and postprocedural risk against the natural disease stroke risk. With the procedural and 30-day risk further confirmed to be <1%, 11 significantly lower than the 5-year risk associated with the natural history of the disease, a decision on whether to offer intervention on top of OMT will become less controversial.…”

“…Technological advancements, including mesh-covered carotid stents for sustained embolic prevention, 11,13,62,64,65,72 taken together with optimized use of temporary protection (with a focus on proximal protection systems for high-risk lesion subsets in particular 11,53,54,56,57,60,66 ) and increased endovascular operator experience 70 may ultimately make CAS a safer procedure that CEA. 35 …”

“…The article by Wissgott et al 62 on the carotid CGuard double-layered embolic prevention stent in the February 2017 issue of the JEVT represents the journal's most recent contribution to the cutting-edge developments in CAS that has included dual-layer stent technology [63][64][65] and new data on the evolution of intraprocedural cerebral protection. 58,66 Following on their work with the RoadSaver doublelayer stent [Terumo, Tokyo, Japan; branded as Casper for commercialization in neuroradiology by Microvention/ Terumo, Saint-Germain-en-Laye, France), 65 Wissgott and colleagues 62 continue their work by evaluating another major dual-layer stent: the CGuard embolic prevention stent (EPS) system (InspireMD, Boston, MA, USA).…”

The Casper carotid artery stent: a unique all metal micromesh stent designed to prevent embolic release

“…The stent can be repositioned in the catheter until up to 50% has been extruded for improved positioning, as determined by the operator. Favorable results have been reported from Europe where the Casper stent is called the Roadsaver stent 3 4. (The Casper stent is undergoing clinical trials with the US Food and Drug Administration as the Roadsaver Stent.…”
