MILTONIATM

Mechanical Bi-Leaflet Heart Valve

The MILTONIATM Mechanical Bi-Leaflet Heart Valve is a low profile bi-leaflet valve consisting of an orifice ring and two mirror image leaflets. The leaflets consist of pyrolytic carbon coated over a graphite substrate. The graphite substrate for the leaflets is tungsten impregnated for radiopacity. The orifice ring consists entirely of pyrolytic carbon. In the full open position, the plane of each leaflet forms a nominal angle of 85° relative to the plane of the orifice ring.The valve sewing ring is constructed of double velour polyester fabric and is mounted on the orifice ring using a titanium stiffening ring and secured with two titanium lock ring and a lock wire. This method of sewing cuff attachment to the orifice allows for rotation of the sewing ring in situ, during surgical placement. Three markers are located in the aortic sewing ring and four markers are located in the mitral sewing ring to assist in the uniform placement of sutures around the valve annulus.

Considerably larger EOAS and excellent patient prosthesis match result in a valve with exceptional hemodynamic performance. Meril recognizes that ppm can be a significant problem in the aortic position. The Miltonia™M AP was created and designed to address this issue.

5-min (1)

The effective orifice area (EOA) of the Miltonia™ valve is larger, size-for-size, than other valve on the market and virtually eliminates patient-prosthesis mismatch (ppm) in the aortic position.

Storage Temperature : 10 °C to 25 °C (50-77 °F)
Storage Solution : Glutaraldehyde
Rinse Procedure : 1 min rinse each in first 3 bowl and store the valve in 4th bowl prior to implantation.
MRI Safety Information : Testing of this device in a magnetic field of 1.5 and 3.0 Tesla has shown that this device is MR conditional.

Tri-leaflet stented bioprosthesis

HEMODYNAMICS SUPPORT

Triple-Composite design provides optimal Effective Orifice Area (EOA)

The three separate leaflets are matched for better leaflet Coaptation which helps minimize Intra-Valvular Regurgitation.

EASE OF IMPLANTABILITY

  1. Black sutures in Mitral valves helps reduce the prole of the commissures, easing the bioprosthesis implantation in the Mitral annulus
  2. Sewing ring designed for better approximation to patient’s annulus and for ease of implantability.
  3. Commissural markers on sewing ring facilitates suture placement and valve orientation.
  4. Elgiloy alloy wireform provides excellent Radio-Opacity and handling characteristics
