Pivot Extend® and Pivot Bridge® are two therapies built on the Pivot-TR platform, designed to treat tricuspid regurgitation, including massive and torrential cases, using a minimally invasive, flow-adaptive approach.
Pivot Extend® is a permanent solution with an adjustable saline-filled spacer, offering long-term therapy for patients ineligible for surgery.
Pivot Bridge® is a temporary implant that stabilizes high-risk or frail patients before surgery or further intervention with potential application as a diagnostic tool.
Both devices use a non-fixated, self-centering spacer and are tailored to match individual patient needs.
