  • Publication number: 20250099170
    Abstract: An ablation apparatus (20) is provided, including: a catheter (21) and an ablation portion (22) connected to a distal end of the catheter (21), where the ablation portion (22) has an expansible property and includes a plurality of ablation members (22a); each ablation member (22a) includes a supporting unit (24), a wall attachment unit (23), and an energy release unit provided on the wall attachment unit (23); a plurality of supporting units (24) are deployed radially outwardly and extend toward the distal end of the ablation portion (22) to be connected to a plurality of wall attachment units (23); when the ablation portion (22) is in a naturally expanded state, at least one wall attachment unit (23) in the ablation portion (22) is independently deformed relative to the adjacent wall attachment units (23). The ablation apparatus (20) can adapt to the morphology of a target tissue and attach well to the target tissue.

  • Publication number: 20230028589
    Abstract: A delivery sheath and a medical device. The delivery sheath includes an outer canal and a traction structure. The outer canal includes a connecting canal, a canal body, and a distal canal. The canal body is located between the connecting canal and the distal canal. The canal body includes a first flexible canal, a spacer canal, and a second flexible canal. The spacer canal is provided between a distal end of the first flexible canal and a proximal end of the second flexible canal. The hardness of the connecting canal is greater than that of the first and second flexible canals, and the hardness of the spacer canal is greater than that of the first and second flexible canals. The traction structure includes a first traction fiber and a second traction fiber.
