A delivery system for mitral valve repair is provided. The delivery system for mitral valve repair includes an inner sheath (3), a middle sheath (2), an outer sheath (1), a first pull wire, a second pull wire, and a push-pull wire. The inner sheath (3), the middle sheath (2), and the outer sheath (1) are nested from inside to outside in sequence and slidably connected along an axial direction of the inner sheath (3). The first pull wire is used to pull the outer sheath (1) and the second pull wire is used to pull the middle sheath (2) so that an outer sheath distal end (12) and a middle sheath distal end (22) can be deflected by different angles in different directions, thereby increasing the flexibility of the delivery system when delivering a device to be delivered (100).

The dielectric layer is exposed to a precursor having a first metal, and a first ammonia treatment is performed. A first purge operation is performed, a second ammonia treatment is performed after the first purge operation, and a second purge operation is performed after the second ammonia treatment to form the barrier layer on the dielectric layer.

Instant messaging method and system, communication information processing method, terminal, and storage medium

The present disclosure provides an instant messaging method and system, a communication information processing method, a terminal, and a storage medium. The instant messaging method includes: receiving, by a first terminal, a sound recorded by a user, and performing sound change processing on the sound recorded by the user to provide a changed sound; sending, by the first terminal, the changed sound after the sound change processing to a second terminal for the second terminal to synthesize the received, changed sound that has gone through the sound change processing with a pre-stored animation, so as to form analog image data and to play the analog image data. The present disclosure has advantages including rich communication forms, convenient operation, and high network transmission efficiency.
