Sponsors with the most current trials registered for this condition.
Medtronic Cardiac Ablation Solutions is the lead sponsor of 12 current trials on ClinicalTrials.gov in our USA, UK, China and Ireland registers, as of the registry sync on 26 September 2026. Completed and withdrawn studies are not counted.
Yes. 6 of its 12 ClinicalTrials.gov trials are recruiting. Eligibility and site contacts are on each trial's record. Only the study team can confirm whether a patient is eligible.
Yes. 1 trial in our Ireland register (ClinicalTrials.gov). Some may be the same study registered in both. See the Irish clinical trials register for sites and contacts.
Every trial, status, phase and condition on this page is copied from public ClinicalTrials.gov and EU CTIS records by a daily sync, grouped by the sponsor name each registry records. It says nothing about the organisation beyond its registered trials, and it is not medical advice.
Everything on this page is copied from public registry records — it is not written from memory, and nothing here describes the organisation beyond its registered trials. Each trial links to its own record so you can check it yourself.
This page is built automatically: a daily sync job reads the registry records behind our trial registers and groups every current trial by its lead sponsor name, ignoring legal-form suffixes such as Inc. or Ltd. A small, hand-checked list joins the same organisation's different registry names (for example its EU legal entity). There is no AI drafting and no per-sponsor editorial pass. The “last verified” date above is the timestamp of that sync, not a review date. Our general editorial approach is described in our editorial standards and corrections policy. The the registries data on this page was last retrieved on 26 Sep 2026.
