Pivot‑TR / Pivot Extend®
Permanent implantPermanent support that moves with the heart.
Pivot Extend® is a permanent, flow-adaptive spacer for secondary tricuspid regurgitation, designed to restore coaptation and sustain heart function through dynamic, self-centering support.

A definitive therapy for patients with massive to torrential TR, sized in the procedure to fit each valve.
Pivot Extend® crosses the tricuspid valve obliquely, held between the IVC and the pulmonary artery without fixation. Flow dynamics and device geometry keep it centered, so support continues as the right heart remodels.
Procedure
Designed to stay centered.
Delivered transfemorally under fluoroscopy, the spacer is inflated to the size the valve needs and then left to find its own center with every beat.

Spacer volume is adjusted intra-procedurally to optimize coaptation.
Components
Three parts, no fixation.
IVC anchor
A spiral structure in the inferior vena cava holds the proximal end without sutures, clips, or tissue penetration.
Balloon spacer
A saline-filled balloon on a nitinol mesh sits across the valve. Its volume is adjusted during the procedure, from 12 to 20 mm in diameter, to match the patient’s anatomy.
PA anchor
An atraumatic extension into the pulmonary artery stabilizes the distal end along the flow axis, preventing migration.
Benefits
Designed around the patient and the procedure.

- Self-centering
- Oblique, flow-guided positioning keeps the spacer in the coaptation gap.
- Patient-specific sizing
- Balloon volume is adjusted in the procedure, from 12 to 20 mm.
- Follows remodeling
- Designed to stay effective as valve geometry changes over time.

- Non-fixated anchoring
- IVC and PA anchors hold the device without sutures, clips, or tissue penetration.
- Leaflet integrity
- Supports coaptation without grasping or damaging the leaflets.
- Retrievable
- Designed for catheter-based retrieval if the treatment plan changes.

- Transfemoral
- Standard percutaneous venous access in the cath lab or hybrid OR.
- Simple imaging
- Fluoroscopy-guided placement, designed without the need for TEE or ICE.
- Fast adoption
- Designed for a short learning curve for interventional teams.
- Tricuspid annulus
- Pivot‑TR spacer
- No-contact zone
Annulus Non-contact
Pivot-TR does not mechanically constrain the annulus, which may help preserve right ventricular function.
