Abstract

The invention discloses a delivery device and system. The delivery device includes a sheath assembly, a terminal and a handle assembly. The sheath assembly includes an inner core tube, a push tube sleeved outside the inner core tube, and a push tube sleeved on the A sheath outside the push tube and axially movable relative to the push tube, the end is connected to the distal end of the inner core tube, the handle assembly is connected to the proximal end of the sheath, and the inside of the push tube A lumen channel is provided for the inner core tube to pass through, a guide wire channel is also provided in the push tube, and a limit mechanism is provided on the end, and the limit mechanism is used to communicate with the guide wire channel The detachable connection of the guide wire threaded in the Beneficial effects of the present invention: by setting a guide wire channel for the guide wire to pass through in the push tube, and setting a limit mechanism detachably connected with the guide wire on the end, the limit mechanism can ensure that the guide wire is transported During the process, it is always connected to the limit mechanism to avoid the displacement of the guide wire and affect the overall positioning accuracy of the system.

Description

technical field [0001] The invention relates to the field of interventional medical devices, in particular to a delivery device and system. Background technique [0002] In the past ten years, endovascular exclusion of aortic stent grafts has been widely used in thoracic and abdominal aortic aneurysms and arterial dissections. treatment method. However, the positioning accuracy of the delivery system in the prior art is not high, and the system cannot accurately and quickly release the stent graft. Therefore, it is necessary to design a reliable delivery system.
