Venous Stenting

Overview

CE Mark Approved, Not yet available in the US.

The Abre™ venous self-expanding stent system is designed for the unique challenges of venous disease.  It offers patients an alternative to more complex surgical procedures.

The Abre system is an innovative venous stent and delivery system for the treatment of venous outflow obstruction. Its features and sizes are optimal for specifically treating the venous system.

Indications

The Abre™ stent is intended for use in the iliofemoral veins for the treatment of symptomatic venous outflow obstruction.

Abre Venous Stent System Components

Abre Venous Stent System Components

  1. Self-expanding stent is available in multiple lengths and diameters.
  2. Triaxial shaft design controls friction and stabilizes stent position during deployment.
  3. Rotating thumb wheel offers predictable placement and auditory feedback.
Flexible: Abre Venous Stent

Flexible: Abre Venous Stent
Venous stents must conform to venous anatomy and follow the curvature of the pelvic vasculature without kinking or fracturing.

Durable: Abre Venous Stent

Durable: Abre Venous Stent
Venous anatomy is dynamic. Often placed in relatively young and healthy patients, venous stents must perform for decades while exposed to persistent and repetitive external forces. Venous stents are frequently required to cross the inguinal ligament and are subjected to bending, compression, and torsion forces during hip flexion.

Strong: Abre Venous Stent

Strong: Abre Venous Stent*
The radial force of the venous stent must oppose recoil forces of the damaged vein. Venous stents also require compression resistance to oppose external forces including arterial or tumor compression. Uniform stent strength is critical to maintaining flow.

Precise: Abre Venous Stent
Placement matters. Venous stents must be deployed precisely to maximize inflow and outflow while preserving the femoral and iliac confluences. Predictable deployment is critical to covering the entire treatment zone the first time.

Full Range of Stent Sizes

The Abre stent is available in a full range of sizes tailored for the iliofemoral venous profile. Using the proper size can reduce stent migration and ensure appropriate stent apposition to the vessel wall.

Design Details

The Abre stent is intended for permanent implant and is provided sterile for single use. It is pre-mounted on a 9 F (3.1 mm), triaxial, over-the-wire (OTW) delivery system.

The Abre stent is cut from a nickel titanium alloy (nitinol) tube in an open lattice design with integral radiopaque markers at the proximal and distal ends to guide placement to the target lesion. The stent delivery system has a tri-axial shaft design which controls friction and stabilizes stent position during deployment.

Abre Stent Ergonomic Handle

Abre Stent Ergonomic Handle

  1. The single luer hub is on the trailing end of the deployment handle.
  2. A locking pin prevents the stent from being deployed before use. It must be removed to operate the thumbwheel.
  3. The thumbwheel rotates to pull back the retractable sheath (silver), while the rotation provides auditory and tactile feedback.
Triaxial Shaft of Abre Venous Stent System

Triaxial Shaft of Abre Venous Stent System

  1. The inner shaft assembly originates at the luer hub and terminates with a flexible catheter tip. It provides a lumen for the guidewire and anchors the stent in place.
  2. The retractable sheath during deployment retracts—or pulls back—inside the isolation sheath to uncover the stent, allowing it to expand.
  3. The isolation sheath provides accuracy and control of stent delivery.

Stent Size Selection

Use this table as a guide to select the appropriate stent size. Using the appropriate stent size is critical to ensure appropriate stent apposition to the vessel wall. Choose a length that extends beyond both sides of the target lesion, with at least 1cm on each side of lesion to reduce the risk of restenosis. Proper stent placement reduces stent migration and ensures appropriate stent apposition to the vessel wall.
