Valiant thoracic stent graft with Captivia delivery system

The Valiant™ Captivia™ stent graft system is designed to treat all lesions of the descending thoracic aorta, including thoracic aortic aneurysms (TAA), type B aortic dissection (TBAD), intramural hematoma (IMH), penetrating atherosclerotic (PAU), and blunt thoracic aortic injury (BTAI).

Overview

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 has been chosen for over 150,000 patients worldwide. It has five years of clinical data across all descending thoracic aortic pathologies.2–4

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.

Angular flexibility and radial strength give the Valiant™ Captivia™ stent graft conformability and optimal seal1

Risks associated 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

  • Eight peak proximal stent design ensures even distribution of radial force for complete vessel wall apposition.
  • Mini support spring enhances proximal apposition and seal.

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.

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.

  • 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.
