Pivot‑TR / Device Comparison

One platform, two treatment paths.

Pivot Extend® and Pivot Bridge® are built on the same Pivot‑TR platform. One is designed to stay, the other to prepare the patient for what comes next.

Pivot Extend®

Permanent implant

Pivot Extend®
Pivot Bridge®

Temporary implant

Pivot Bridge®

Shared platform

What they have in common.

Transfemoral delivery

Femoral vein → IVC → right atrium → PA, under fluoroscopy.

Non-fixated anchoring

Spiral IVC anchor and atraumatic PA anchor, without tissue penetration.

Self-centering spacer

Oblique, flow-guided positioning that adapts to remodeling.

Retrievable

Both are designed for catheter-based retrieval.

Key differences

Where they differ.

How long it stays

Pivot Extend®

Permanent

Pivot Bridge®

Temporary, up to 3 weeks

What it is for

Pivot Extend®

Definitive therapy for secondary TR

Pivot Bridge®

Pre-habilitation and diagnostic use, in preparation for definitive therapy

How blood flows

Pivot Extend®

Self-centering oblong spacer with a flow-adaptive, saline-filled balloon

Pivot Bridge®

Self-centering oblong spacer with flow apertures

How it adapts

Pivot Extend®

Spacer volume adjustable during the procedure (12–20 mm diameter)

Pivot Bridge®

Bridge to surgery, transcatheter repair, or replacement

How it comes out

Pivot Extend®

Removable by transcatheter retrieval

Pivot Bridge®

Removable by transcatheter retrieval, or manually at the time of surgery
