Symetis / Boston Scientific: ACURATE neo™ & ACURATE TF DS - (CE)

Transcatheter aortic valve devices

The ACURATE neo Aortic Valve with Transfemoral and Transapical Delivery Systems, is a self-expanding, supra-annular valve, offering an intuitive procedure, predictable release, stable positioning, and has demonstrated excellent clinical outcomes.

ACURATE neo™ & ACURATE TF DS Introduction

The Symetis transfemoral TAVI system consists of the ACURATE neo™ Aortic Bioprosthesis and the ACURATE TF™ Transfemoral Delivery System. The self-positioning bioprosthesis is composed of a porcine pericardial tissue valve sewn into a self-expanding nitinol stent covered with an anti-leak porcine pericardial skirt. Its transfemoral delivery system is designed for a simple 3-step deployment and stable positioning within the native annulus. The product is compatible with the 15F Terumo Solopath or 18F Cook sheaths. The product is available in three sizes (S, M, L) to treat patients with aortic annulus diameters from 21mm to 27mm.

The rollout of ACURATE neo will be modeled on the successful commercialization of Symetis's transapical system, ACURATE TA, which has witnessed a remarkably rapid uptake in core European markets. Clinical trials include the use of ACURATE Neo™ AS Aortic Bioprosthesis for implantation using the ACURATE neoTM AS TF Transfemoral Delivery System in patients with severe aortic stenosis.

Special features:

  • Compatible with 15 Fr balloon-expandable SoloPath sheath
  • Self-seating, self-sealing design for optimal positioning and sealing and reduced PV leak
  • Unique top-down deployment for stable and controlled valve release movie 28 [video=28 chapter=3].

Product advantages:

  • Intuitive procedure: flexible transfemoral and low-profile transapical delivery systems and self-aligning valve
  • Predictable release: safe two-step, top-down deployment with stable hemodynamics
  • Stable Positioning: effective self-fixationp and self-sealing
  • Superior outcomes: very low gradients and new pacemarker rates
