InspireMD, Inc. NSPR announced positive 30-day results from the CGUARDIANS II clinical trial evaluating its CGuard Prime 80 cm carotid stent implant for use in transcarotid artery revascularization (TCAR) procedures. The study met key safety and efficacy endpoints, reporting a 100% acute device success rate and no deaths, strokes, myocardial infarctions or stent thrombosis within 30 days.
The latest data strengthen InspireMD's case for a potential FDA approval of the CGuard Prime 80 cm implant in the second half of 2026. For investors, the approval could significantly expand the company's addressable market beyond carotid artery stenting procedures and provide access to more than 35,000 TCAR procedures performed annually in the United States.
Likely Trend of NSPR Stock Following the News
Shares of NSPR have traded flat since the announcement of the news. In the year-to-date period, shares of the company have lost 57.3% compared with the industry’s 17.4% decline. The S&P 500 increased 8.7% in the same time frame.
The positive CGUARDIANS II data are likely to bolster InspireMD's long-term growth prospects by supporting the regulatory expansion of the CGuard Prime platform into the rapidly growing TCAR market. If approved, the 80 cm implant would enable the company to address a significantly larger patient population and diversify its revenue stream beyond traditional carotid artery stenting procedures. The encouraging safety and efficacy profile may also strengthen physician confidence and drive broader adoption of the CGuard platform, positioning InspireMD to capitalize on increasing demand for minimally invasive stroke-prevention therapies.
NSPR currently has a market capitalization of $34.2 million.

More on the News
The CGUARDIANS II study is a prospective, multi-center, single-arm pivotal trial designed to evaluate the acute device success and technical success of the CGuard Prime 80 cm carotid stent implant when used with the FDA-cleared ENROUTE TCAR neuroprotection system. The trial enrolled 50 patients across 11 sites in the United States, comprising individuals considered at high risk for adverse events from carotid endarterectomy. The study met its key endpoints, with acute device success achieved in all 50 patients, translating to a 100% success rate.
Further, the trial reported no deaths, strokes or myocardial infarctions within 30 days of the procedure. No cases of stent thrombosis were observed during the 30-day follow-up period, while complete stent patency was recorded in all evaluable subjects. According to the company, these encouraging findings support the safety and efficacy profile of the CGuard Prime 80 cm implant in TCAR procedures and strengthen its ongoing Premarket Approval supplement application with the FDA, which is currently under review. InspireMD expects a potential approval in the second half of 2026, which could expand the use of the CGuard Prime platform into the growing U.S. TCAR market.
Favorable Industry Prospect for NSPR
Per a report by Growth Market Reports, the global TCAR systems market size reached $1.14 billion in 2024, driven by the increasing prevalence of carotid artery disease and advancements in minimally invasive vascular procedures.
