Product details

Deploy durability with Valiant™ Captivia™ system

Valiant™ Captivia™ thoracic stent graft system maintains vessel wall apposition and fixation, regardless of angulation and oversizing.1 Clinically supported by low type Ia endoleak rate (0% at 5 years).2 The stent graft system has over a decade of worldwide experience and chosen for over 150,000† patients worldwide. It has five years of clinical data across all descending thoracic aortic pathologies.2–4

This is the Valiant™ thoracic stent graft with the Captivia™ delivery system, shown as a pre-insertion image next to a fluoroscopic image of the system apposed in the vessel wall.

The Valiant™ Captivia™ stent graft is the only device that maintains complete apposition regardless of angulation and oversizing.1

Results

The Valiant™ Captivia™ stent graft system remained apposed to the aortic wall at each increment of neck angulation and degree of oversizing in a simulated environment.

For the other stent grafts tested, lack of device wall apposition was observed between the proximal anchorage segment and the inferior aortic wall.

This is a chart showing the stent graft apposition to the aortic wall at each increment of neck angulation and degree of oversizing in a simulated environment.

 

ꝉ10–19% device oversizing.

Risks assocatied with TEVAR procedures may include rupture, conversion to open repair, or secondary procedures.

Features

How does Valiant™ Captivia™ system maintain a continuous seal in a dynamic environment?

 

Achieving and maintaining a continuous seal is critical for TEVAR durability.

  • The Valiant™ Captivia™ system establishes and maintains a continuous seal and optimizes apposition in a dynamic environment.
  • It is the only device that maintains complete vessel wall apposition regardless of angulation and oversizing.1

Continuous seal

  • 8 peak proximal stent design ensures even distribution of radial force for complete vessel wall apposition.
  • Mini support spring enhances proximal apposition and seal.
This is an image of the Valiant™ thoracic stent graft with a close-up showing the eight peak proximal stent design and support spring.

Ease of access

  • Crossing profile is similar to or lower than other thoracic stent grafts for ease of access.
  • Hydrophilic coating facilitates stent graft delivery.
This is an image of the Captivia™ delivery system for use with the Valiant™ thoracic stent graft.

Precise deployment

  • Platinum-iridium Figur8 markers provide high visibility for accurate placement. 
  • Three-step deployment with tip capture release provides controlled deployment and precise placement in the thoracic aorta.
Initiate deployment, hold delivery system with one hand on front grip, use other hand to rotate the slider counterclockwise

Step 1

Slow, controlled deployment for precise placement

Continue withdrawing graft until distal spring is fully deployed; for rapid deployment, hold trigger and pull slider back

Step 2

Quick deployment option, if desired

To release proximal bare stent, rotate tip capture release handle counterclockwise then pull tip capture release handle back

Step 3

Tip capture release

This is an image of the Valiant™ thoracic stent graft showing flexibility next to a family of stent grafts to show the broad selection of proximal and distal components to allow for customization for a variety of patients.
 
  • Absence of a longitudinal bar allows for enhanced flexibility and kink resistance.
  • Broad selection of proximal and distal components leads to many combinations to customize for a variety of patients.

Indications

The Valiant™ thoracic stent graft with the Captivia™ delivery system is indicated for the endovascular repair of all lesions of the descending thoracic aorta (DTA) in patients having the appropriate anatomy, including:

  • Iliac or femoral artery access vessel morphology that is compatible with vascular access techniques, devices, or accessories;
  • Nonaneurysmal aortic diameter in the range of 18 mm to 42 mm (fusiform and saccular aneurysms/penetrating ulcers), or 18 mm to 44 mm (blunt traumatic aortic injuries) or 20 mm to 44 mm (dissections); and
  • Nonaneurysmal aortical proximal and distal neck lengths ≥ 20 mm (fusiform and saccular aneurysms/penetrating ulcers), landing zone ≥ 20 mm proximal to the primary entry tear (blunt traumatic aortic injuries, dissections). The proximal extent of the landing zone must not be dissected.
