A cyberattack on U.S. medical device maker Boston Scientific is causing an ongoing “global disruption” to its operations, according to a federal regulatory filing on Wednesday, the latest healthtech giant to face a cyberattack in recent weeks.

The Massachusetts-based company, which makes medically implanted devices like pacemakers and defibrillators, confirmed in a filing with the U.S. Securities and Exchange Commission that on Tuesday it began experiencing “disruptions and limitations of access” to its IT systems and business applications critical for its operations.

Boston Scientific said the cyberattack has affected its ability to ship and process orders, but has not said whether the disruption extends to customers with medical devices and implants.

When asked by TechCrunch, Boston Scientific spokesperson Chanel Hastings shared the company’s public statement, but would not comment on whether patients are affected by the cyberattack, say what steps patients should take, or answer questions about the nature of the incident.

Boston Scientific treats around 48 million patients a year, according to its website.
