Clinical Evidence

Clinical progress across Pivot Bridge and Pivot Extend.

In its first‑in‑human study, Pivot Bridge reduced tricuspid regurgitation, improved right‑heart structure, and eased symptoms in patients with severe secondary TR. Building on this clinical foundation, Pivot Extend is being evaluated in an ongoing Early Feasibility Study in Australia, expected to conclude by the end of 2026. Tau Medical is also expanding clinical and compassionate‑use experience across key regions.

Compassionate-use experience

Challenging anatomy. Complex patients.

Pivot Extend has been used under compassionate-use pathways in patients with severe tricuspid regurgitation and challenging anatomical or clinical characteristics, including those previously considered untreatable.

No limit to annular dimension

Largest coaptation gap to date was ~42 mm.

Pacemaker leads

multiple lead-associated TR cases

3 regions and counting

EU, Oceania, Asia

High-risk profile

cases with RV dysfunction, pulmonary hypertension, renal impairment, or prior interventions
