Superior anti-calcification performance

Micro-ExTM processing: Removes residual cellular debris and phospholipids from the pericardium while eliminating glutaraldehyde active groups. Series of animal studies demonstrate that Micro-ExTM processing reduces valve leaflet calcification by over 99%, significantly delaying calcification progression.

Excellent Hemodynamic Performance

The Elgiloy high-elastic alloy valve frame reduces stress concentration, significantly improving the fatigue resistance.
A well-designed frame and leaflet structure provide the valve with a larger effective orifice area, while physiological leaflet opening and closing ensure optimal forward blood flow.
The thinner sewing ring allows for larger valve sizes, thereby enhancing hemodynamic performance.
The undulating design fully conforms to the shape of the aortic annulus, enabling complete supra-annular implantation, which is particularly beneficial for patients with narrow aortic roots.

       

Outstanding Biocompatibility

Rapid endothelialization (less than 30 days) after implantation
Studies indicate that endothelial cells coverage on the valve leaflet surfaces play a crucial role in maintaining normal valve structure and function:
① The endothelial cell membrane forms a barrier that prevents the infiltration of blood components/tissue fluid components and inhibits calcium salt deposition.
② The endothelial cell membrane prevents blood components from penetrating into the collagen fibers of the leaflet tissue, avoiding loosening and disorganization of collagen structures.
③ The endothelial cell membrane possesses excellent antithrombotic properties.

Softer Leaflets, Closer to Natural

The next-generation innovative pericardial processing technology (Micro-Ex) enhances pericardial strength while maximizing its silk-like flexibility. The flexible valve leaflets provide superior coaptation height, faster opening and closing response, and increased effective orifice area.

Exquisite Manufacturing Process

Finite element analysis determines the maximum stress on the valve leaflets, while the fiber orientation of the pericardium is precisely aligned to maximize leaflet strength.

Comfortable Implantation Experience

• The multi-functional valve holder retracts the valve leaflets prior to implantation, effectively preventing contact with the left ventricular wall and suture entanglement during the implantation.

• The unique three-marker design on the sewing ring allows the optimal valve positioning during implantation, significantly improving ease of implantation, has been clinically validated.

• The unique honeycomb design of sewing ring not only minimizes needle resistance but also effectively prevents perivalvular leakage.

• The low valve profile height and smooth commissures facilitate safe implantation through small incisions.
