Document Type and Number:
WIPO Patent Application WO/2023/143359
Kind Code:
A1
Abstract:
A branch sheath comprises a connection tube (21), a covered cannula (22), a control wire (11), a binding coil (24), and a first fixing coil (23). The distal end of the connection tube (21) is connected to the proximal end of the covered cannula (22). The control wire (11) passes through the connection tube (21) and the covered cannula (22), and two ends of the control wire (11) respectively extend out of the connection tube (21) and the covered cannula (22). The proximal end of the binding coil (24) is connected to the distal end of the connection tube (21), and the distal end of the binding coil (24) passes through and extends out of the covered cannula (22), and is used for passing through the hole of a bare end (411) of a branch stent (41) and extending out of the hole of the bare end (411), so as to pull and fix the bare end (411) of the branch stent (41). The distal end of the control wire (11) passes through the part, extending out of the hole of the bare end (411), of the binding coil (24). The proximal end of the first fixing coil (23) is connected to the distal end of the connection tube (21), and the distal end of the first fixing coil (23) is connected to a main stent (31).
