Abstract

The invention provides a branch sheath and an intravascular stent transport device. Wherein the near end of a binding coil in the branch sheath is connected with the far end of the connecting tube, and the far end of the binding coil penetrates through and extends out of the covered cannula and is used for penetrating through a bare end hole of the branch stent and extending out of the bare end hole, so that the compressed bare end of the branch stent is pulled and fixed, and the situation that after the main body stent is released, the binding coil is damaged is avoided. The branch supports are pulled by the main body support to shift. The control wire penetrates through the portion, extending out of the hole of the bare end, of the binding coil and is used for controlling release of the branch stent and being pulled into the branch blood vessel again at any time after the branch stent is separated from the preset position in the operation, and accurate positioning is achieved. The near end of the first fixing coil is connected with the far end of the connecting pipe, and the far end of the first fixing coil is connected with the main body support, so that integrated transmission is facilitated. Therefore, the branch sheath and the intravascular stent transportation device provided by the invention not only can prevent the displacement of the branch stent and ensure the accuracy of the release position, but also are simple to operate and high in feasibility.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a branch sheath and a vascular stent delivery device. Background technique [0002] With the development of intraluminal devices and minimally invasive interventional therapy, intravascular stent placement has become a common treatment method for arch arterial vascular diseases. The aneurysm, breach or dissection is isolated from the blood, avoiding the risk of death due to aneurysm rupture and dissection expansion and bleeding. [0003] Although minimally invasive interventional covered stent grafts have the advantage of less trauma than thoracotomy, there are still some problems, especially the handling of branch vessels. At present, the Castor bracket adopts the integrated design of the branch bracket and the main bracket. Before the implantation of the main body stent, the guide catheter and the guide wire are introduced through the puncture of the branch vessel of ...
