DAFODIL NEO

Advantages and Properties

Trusted durability

Properties

1. Three leaflets are independently laser cut to provide precision and uniformity in size and shape for better haemodynamics and durability.
2. Triad-frame design with elgiloy alloy wireform provides Robustness via Superior spring efficiency, Fatigue and Corrosion resistance.
3. Leaflets are treated with proprietary anti Calcification treatment to increase the valve’s long term durability.
4. In-vitro testing: 200 M cycles proven in-vitro durability as per ISO 5840.
5. Protected by Anti Ca+ anticalcification treatment that helps in removing aldehydes and phospholipids.

 

Ease of Implantability

Properties

Aortic

1. New 17mm size offering suited for small aortic annulus (custom made device on prescription basis only).
2. Commissural markers on sewing ring facilitates suture placement and valve orientation.

Mitral

1. Reduced mitral protrusion to provide greater ease of implantability.
2. Locking threads and Rotator are additional components in the construction of the Mitral valve.
3. Polyester Black sutures in Mitral valves helps reduce the profile of the commissures, easing the bio-prosthesis implantation in the Mitral annulus.
4. Separate long holder handle is provided, making it suitable for minimally invasive procedures.

 

Hemodynamics

Properties

1. The pericardial leaflets are matched in all aspects (triple composite design) to ensure optimal coaptation that helps in minimising valve regurgitation.
2. Dafodil Neo comes with a reduction in the stent diameter to tissue annulus diameter ratio that translates in superior hemodynamics for a given patient annulus.

 

Indication

 

An Aortic Dafodil Neo™ Pericardial Bioprosthesis is indicated for use in patients whose aortic valvular disease is sufficiently advanced to warrant replacement of their natural valve with a prosthetic one. It is also intended for use in patients with a previously implanted aortic valve prosthesis which is no longer functioning adequately and requires replacement. In the latter case, the previously implanted prosthesis is surgically excised and replaced by the replacement prosthesis.
