Document Type and Number:
WIPO Patent Application WO/2023/051078
Kind Code:
A1
Abstract:
A delivery catheter (1), an implant delivery system, and a working method. A balloon structure of the delivery catheter (1) comprises an expandable component and a balloon body (140); the expandable component is provided in the balloon body (140) in an expandable mode and sleeved at the distal end of a guide wire cavity tube (210); an implant is provided on the balloon body (140) and is provided in the middle of the expandable component in a position-limiting mode in the axial direction in a conveying process; and the expandable component is used for providing radially outward supporting force from the middle of the balloon body (140) during expansion so as to enable a distal-end inner environment and a proximal-end inner environment of the balloon body (140) to be communicated, such that the implant can be expanded stably and uniformly, and the implant can be expanded symmetrically; and the risk that the implant moves in the axial direction of the delivery system during conveying and releasing can be solved.
