Pivot‑TR / Pivot Extend®

Permanent implant

Permanent 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.

Pivot Extend®

Technology

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.

Balloon inflation. Volume is adjusted from 12 to 20 mm during the procedure. Device rendering.
The spiral anchor stays fixed in the IVC while the distal anchor and spacer move with the heart, keeping the device aligned with cardiac motion. Device rendering.

Components

Three parts, no fixation.

Tricuspid valve IVC PA
Schematic, not to scale.

IVC anchor

A spiral structure in the inferior vena cava holds the proximal end without sutures, clips, or tissue penetration.

Benefits

Designed around the patient and the procedure.

Adaptive
Adaptive
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.
Atraumatic
Atraumatic
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.
Accessible
Accessible
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.
