LeMaitre Vascular, Inc. Data Breach Notice (Vermont Attorney General): What Was Exposed & What To Do

LeMaitre Vascular, Inc. notified Vermont residents of a data breach in a filing reported to the Vermont Attorney General on September 18, 2026. According to that notice, the incident involved a small number of people—two individuals—and the company listed Social Security numbers, government ID numbers, and health records among the information exposed.

Public detail remains limited to what appears in the state filing. The notice establishes that sensitive personal and health-related data were involved for the affected Vermont residents, which is why the disclosure matters even at this scale: those categories of information can support identity misuse and related harm if they reach the wrong hands.

Breaking down the breach

What is known comes from LeMaitre Vascular, Inc.’s data breach notice as reported to the Vermont Attorney General on September 18, 2026. The filing states that the company notified Vermont residents and that two people were affected. The notice names Social Security numbers, government ID numbers, and health records among the exposed information.

The public record does not describe how the incident occurred, when unauthorized access began or ended, what systems were involved, or whether data were exfiltrated in full or only accessed. Method, timeline beyond the reporting date, and technical scope are undisclosed in the available summary. No threat actor is attributed in the facts provided.

How a breach like this happens

Incidents that lead to notices naming Social Security numbers, government IDs, and health records often follow familiar patterns, though none of these patterns is confirmed for this specific case. Attackers may gain entry through stolen or phished credentials, unpatched remote-access software, compromised email accounts, or misconfigured cloud storage. Once inside, they may search for files or databases that hold identity and clinical information because those records retain value for fraud and secondary misuse.

In other cases, a vendor or business partner with access to patient or employee data is compromised, and the primary organization learns of the exposure only after an investigation. Ransomware groups sometimes claim to have stolen data before encryption; other actors quietly copy records without making demands. Organizations typically discover the problem through internal monitoring, law-enforcement notice, or a third-party alert, then work to determine whose information was involved and what categories were present. Without a published forensic account, it is not possible to say which path applied here.

Who is LeMaitre Vascular, Inc.?

LeMaitre Vascular, Inc. is a medical-device company operating in the vascular and related healthcare sector. Firms of this kind design, manufacture, and sell products used in vascular surgery and related care. In the ordinary course of business they may hold employee records, customer or distributor contacts, and—when they interact with clinical settings, trials, or patient-support programs—information that can include health-related details and government identifiers.

A breach at such an organization is consequential because healthcare-adjacent companies often process data that is both personally identifying and medically sensitive. Even when the number of people named in a state notice is small, the categories of data can still create lasting risk for those individuals. Regulators require notice when certain personal information is involved so that residents can take protective steps.

What was likely exposed

The Vermont notice lists specific categories. Public detail on exact file contents, full data fields, or whether every listed type applied to both individuals is otherwise limited. Based on the filing, the following were named as exposed:

• Social Security numbers
• Government ID numbers
• Health records

Organizations in the medical-device and healthcare-support sector commonly maintain additional records such as names, addresses, dates of birth, insurance or billing identifiers, and employment data. Whether any of those further elements were involved in this incident is unconfirmed. Readers should treat only the types stated in the notice as established for this event.

What's at stake

For the two people named in the Vermont filing, exposure of Social Security numbers and government ID numbers raises the possibility of identity theft, fraudulent account opening, or tax- and benefits-related misuse. Health records can support targeted scams, insurance fraud, or unwanted disclosure of medical information. Those harms do not always appear immediately; misuse can surface months later.

For the organization, a breach notice triggers legal notification duties, potential regulatory scrutiny, and the cost of investigation and remediation. Trust with patients, clinicians, and partners can be affected even when the headcount of affected individuals is low. The filing does not state financial losses, litigation outcomes, or operational disruption, so those remain outside what is publicly confirmed here.

Were you affected?

If you have a connection to LeMaitre Vascular, Inc.—as a Vermont resident who received a notice, an employee, a patient in a related program, or someone who otherwise shared identity or health information with the company—review any official letter carefully for the date range and data types it describes. Consider placing a fraud alert or credit freeze with the major credit bureaus, monitoring credit reports and explanation-of-benefits statements, and being cautious about unsolicited calls or emails that reference the incident or request verification of personal details.

Keep copies of any breach notice you receive. If you did not receive a letter but remain concerned, you can still take the same monitoring steps. Readers can also run a free exposure scan of their email to check whether their information has surfaced in known breach data, which may help indicate whether the same address appears in other incidents beyond this notice.
