Embodiment Construction

[0064] see figure 1 , referring to the remaining figures, the stent valve with an inner tongue structure of the present invention includes a radially deformable tubular mesh stent body 1 , leaflets 2 , membrane 3 and an inner tongue structure 4 . The inner tongue-shaped structure 4 is connected to the inner side of the stent body 1, and forms a stent with an inner tongue-shaped structure together with the stent body. The inner tongue-like structure 4 contains at least one inner free tongue that can move to the inside of the stent. The inner free tongue constitutes the connecting edge between the valve leaflet 2 and the covering film 3. The leaflet 2 and the covering film 3 are connected to the inner free tongue, or through the inner free tongue. The free tongue is connected with the frame body.

[0065] The tubular mesh stent body in the present invention can be a straight tubular mesh stent, a drum shaped mesh stent with a drum-shaped structure in the middle section, or a ra...

Abstract

A stent valve includes a tubular netted stent body (1) deformable radially and leaflets (2) and an overlay film (3), and also includes an inner tongue structure (4) connected to the inside of the stent body (1). The inner tongue structure (4) and the stent body (1) cooperatively constitute a stent with an inner tongue structure. The inner tongue structure (4) contains at least one inner free tongue movable to the inside of the stent. The inner free tongues constitute connecting rims of the leaflets (2) and the overlay film (3). The leaflets (2) and the overlay film (3) connect with the inner free tongues, or connect with the stent body (1) via the inner free tongues. The weaving method of the woven stent with an inner tongue structure includes a first weaving and a second weaving.
