Abstract: An ablation system (3300) includes a support (3310), a delivery device (3320) configured to deliver the support (3310) to a target tissue, and an ablation element (3330) including a first conductive portion (3331) and a second conductive portion (3332). The first conductive portion (3331) is provided on the support (3310). The second conductive portion (3332) is provided on the support (3310) or the delivery device (3320) or independently from the support (3310) and the delivery device (3320). Both the first conductive portion (3331) and the second conductive portion (3332) are electrically connected to an external pulse ablation source, and the first conductive portion (3331) and the second conductive portion (3332) are configured to transmit pulse ablation energy with different polarities to the target tissue.

Abstract: A venous valve replacement device includes a stent with a blood flow channel and two leaflets connected to the stent, wherein one side of each leaflet is configured as a fixed edge connected with the stent, and the other side is configured as a movable edge, and wherein the movable edges of the two leaflets cooperates with each other to open or close the blood flow channel, and the movable edges of the two leaflets are provided with flaps that attach to each other in a closed configuration.

Abstract: A left atrial appendage occluder with advanced connection manner and a manufacturing method thereof are provided. The left atrial appendage occluder includes a sealing portion and an anchoring portion. Each of the sealing portion and the anchoring portion is provided with a connection part formed by converging a corresponding shape of the sealing portion or the anchoring portion respectively. The connection parts of the sealing portion and the anchoring portion extend toward each other to be fixed and misaligned with each other.
