Boston Scientific Shares Fall on Watchman Usage Slowdown

Boston Scientific (BSX) shares fell about 12% on Wednesday to their lowest in more than two years, after the medical device maker flagged declining usage of its heart disease device Watchman. CEO Michael Mahoney said at Bernstein's annual conference that the company has seen a declining usage of Watchman stand-alone procedures in 2026.

Changing Treatment Patterns

Mahoney noted that doctors are increasingly combining Watchman procedures with other heart treatments during a single visit, rather than performing it as a standalone procedure. Watchman is a small implant placed in the heart to prevent blood clots and strokes, especially in patients with atrial fibrillation who cannot take long-term blood thinners.

Growth Expectations

The company expects flat dollar growth from the first quarter to the second quarter, and likely in the third quarter. Boston Scientific maintained its full-year organic revenue growth forecast of 6.5% to 8%, a range it had previously narrowed from higher expectations. Analysts say the update pushes off a recovery in investor trust.
