InspireMD Announces 30-Day Results from the CGUARDIANS II Clinical Trial of the CGuard Prime 80 cm Implant for Use in TCAR Procedures

MIAMI, June 11, 2026 — InspireMD, Inc. (Nasdaq: NSPR) (“InspireMD” or the “Company”), developer of the CGuard® Prime carotid stent system for the prevention of stroke, today announced 30-day outcomes from the CGUARDIANS II clinical trial of the CGuard Prime 80cm implant for use in transcarotid artery revascularization (TCAR) procedures. InspireMD anticipates potential approval of the CGuard Prime 80 cm stent implant in the second half of this year.

Key 30-day outcomes observed in the CGUARDIANS II trial include:

• Acute device success was achieved in 100% (50/50) of patients;
• No deaths, strokes, or myocardial infarctions were reported within 30 days;
• No stent thrombosis was observed within 30 days;
• Complete stent patency observed at 30 days in evaluable subjects.

Dr. Patrick J. Geraghty, professor of surgery and radiology at Washington University School of Medicine in St. Louis and co-lead investigator of the CGUARDIANS II study, commented, “The 30-day results observed in the CGUARDIANS II trial suggest that the CGuard Prime 80 cm stent may deliver exceptional safety and efficacy when used with a TCAR approach. Notably, the 100% acute device success rate with zero major adverse events has the potential to make CGuard Prime the gold standard implant for high-risk patients undergoing TCAR procedures. I look forward to incorporating it into my own practice, if approved.”

“We believe the 30-day CGUARDIANS II results represent a significant achievement in our quest to tap into the large and growing TCAR market,” said Marvin Slosman, CEO of InspireMD. “Together with our recently initiated CGUARDIANS III clinical trial of our proprietary SwitchGuard neuroprotection system, we potentially have line-of-sight to offering the full TCAR toolkit, subject to regulatory review and approval, leveraging our best-in-class CGuard Prime Carotid Stent System with its unmatched clinical outcomes, for the more than 35,000 TCAR procedures that are performed in the U.S. every year.”

CGUARDIANS II is a prospective, multi-center, single-arm pivotal study that enrolled 50 patients across 11 trial sites. The objective of the study is to evaluate acute device success and technical success of the CGuard Prime 80 cm when used in conjunction with the FDA-cleared ENROUTE TCAR neuro-protection system in patients considered at high risk for adverse events from carotid endarterectomy.
