Gradient cross linking and modifying type durable prosthetic biological valve and preparation method thereof |
| abstract |
The invention belongs to the field of medical equipment, and relates to a gradient cross linking and modifying type durable prosthetic biological valve and a preparation method thereof. According to the preparation method, a compound chemical modification and gradient immersing manner is mainly adopted to taw pericardium material so as to prepare the gradient cross linking and modifying type durable prosthetic biological valve during the chemical modification process of the prosthetic biological valve, and the performance attenuation caused by chemical modification saturation can be avoided so as to prevent calcification. Therefore, the service life of the biological valve can be prolonged. |
