Company Description
InspireMD, Inc. (NSPR) is a medical device company whose common stock is quoted on the Nasdaq Capital Market under the ticker symbol NSPR, according to its SEC filings. The company is described in public disclosures and press releases as the developer of the CGuard® Prime carotid stent system for the prevention of stroke and as a business that seeks to utilize its proprietary MicroNet™ mesh technology in carotid stenting.
Business focus and core technology
According to multiple company press releases, InspireMD focuses on the development and commercialization of carotid stent systems that incorporate its proprietary MicroNet™ mesh technology. The company states that it aims to make its products the industry standard for carotid stenting by providing outstanding acute results and durable, stroke-free long-term outcomes. Its disclosures highlight CGuard® Prime as a carotid stent system designed for the treatment of carotid artery stenosis and for the prevention of stroke.
The company’s earlier Polygon description notes that InspireMD is a United States based medical device company focused on a proprietary MicroNet stent platform technology for the treatment of complex vascular and coronary disease, with products including the CGuard carotid Embolic Prevention System (CGuard EPS) and the MGuard Prime Embolic Protection System (MGuard Prime EPS. That description also states that the company has generated a majority of its revenue from sales of CGuard EPS.
CGuard® Prime carotid stent system
In recent SEC filings and news releases, InspireMD describes itself as the developer of the CGuard® Prime carotid stent system for the prevention of stroke. A Form 8-K filed on June 24, 2025 reports that the company received FDA premarket approval (PMA) for the CGuard Prime Carotid Stent System in the United States. A later Form 8-K dated July 9, 2025 references a press release announcing the U.S. commercial launch of CGuard® Prime. Subsequent earnings-related news indicates that the company initiated a U.S. commercial launch and completed carotid procedures across hospitals using CGuard Prime.
Company press releases explain that CGuard® Prime is a carotid stent system that incorporates MicroNet™ mesh technology. InspireMD’s descriptions emphasize its goal of providing strong acute performance and durable outcomes in carotid interventions and of supporting a stent-based approach to carotid revascularization.
MicroNet™ mesh platform and product history
Across its communications, InspireMD consistently identifies MicroNet™ mesh as its proprietary technology platform. The Polygon description characterizes this as a MicroNet stent platform for complex vascular and coronary disease, and lists CGuard EPS and MGuard Prime EPS as products based on this platform. More recent company press releases describe MicroNet™ mesh as the core technology used in CGuard® Prime for carotid stenting, and the company states that it seeks to use this mesh technology to provide stroke-free long-term outcomes.
Clinical evidence and pivotal trials
InspireMD highlights clinical data supporting its carotid stent system. A January 2026 news release reports that results from the company’s C-GUARDIANS pivotal trial of the CGuard® Prime carotid stent system were published in the Journal of the American College of Cardiology (JACC). According to that release, the trial evaluated the safety and efficacy of carotid artery stenting with the company’s MicroNet™ covered stent in patients with asymptomatic carotid stenosis and included both symptomatic and asymptomatic patients with obstructive carotid disease at high risk for complications with carotid endarterectomy.
The C-GUARDIANS trial, as described in the publication summary provided by the company, enrolled patients across sites in the United States and Europe and assessed a composite primary endpoint including death (all-cause mortality), stroke, or myocardial infarction through 30 days, and ipsilateral stroke from 31 to 365 days. InspireMD states that the trial demonstrated low rates of disabling stroke or myocardial infarction through 30 days and low ipsilateral stroke rates through one year, with no unexpected device-related adverse events reported.
In addition to C-GUARDIANS, InspireMD has referenced external clinical evidence that is relevant to carotid artery stenting. A November 2025 press release notes the publication of the NIH-sponsored CREST-2 study in the New England Journal of Medicine and describes the company’s view that CREST-2 data support the role of carotid artery stenting combined with medical therapy for patients with severe asymptomatic carotid stenosis. The company states that these external data, together with its own C-GUARDIANS trial results, support a shift toward an endovascular-first or stent-based approach in certain segments of carotid disease.
Regulatory milestones and U.S. commercialization
InspireMD’s SEC filings and press releases describe a sequence of regulatory and commercial milestones for CGuard® Prime. A Form 8-K dated June 24, 2025 reports that the company received FDA PMA approval of the CGuard Prime Carotid Stent System in the United States on June 23, 2025. A subsequent Form 8-K dated July 9, 2025 references a press release announcing the U.S. commercial launch of CGuard® Prime for the prevention of stroke.
Later financial results releases, referenced in the company’s November 4, 2025 Form 8-K, state that InspireMD initiated its U.S. commercial launch of CGuard Prime and completed carotid procedures across leading hospitals. The company also notes that this initial U.S. commercial activity contributed to revenue and that it has been expanding its U.S. personnel, particularly its commercial team, in connection with the launch.
Geographic activity
The Polygon description of InspireMD states that the group operates in Italy, Germany, Russia and other countries. More recent company communications describe clinical trial activity across sites in the United States and Europe and reference global experience with implants of its device. For example, a November 2025 press release notes that CGuard has been supported by more than 65,000 global implants and extensive real-world evidence. These statements indicate that InspireMD’s technology has been used in multiple international markets.
