FDA approved new software for Abbott's CardioMEMS HF System on October 6. The CardioGuide HF app shows pulmonary artery pressure readings on a patient's smartphone. Until now those readings went only to the care team.

The same approval covers Dynamic Treatment Plan, which lets a clinician set personalized medication adjustment protocols tied to pressure changes. Abbott plans to launch both later in 2026. The implant itself does not change. It is still a catheter-delivered sensor in the pulmonary artery, used for more than a decade to catch worsening heart failure weeks before symptoms appear.

No hardware moved here, so the review work sat in labeling and human factors. Handing a patient a number that was clinician-only changes who acts on it, and that is the question FDA had to be satisfied on.
