Abstract

The invention discloses a transporting device and system. The transporting device comprises a sheathing canal assembly and a handle assembly connected to the near end of the sheathing canal assembly,wherein the sheathing canal assembly comprises an inner core pipe, a push pipe sleeving the outer part of the inner core pipe, and a sheathing canal which sleeves the outer part of the push pipe and axially moves relative to the push rod; a lumen passage allowing the inner core pipe to penetrate is arranged in the push pipe; the sheathing canal assembly also comprises a support member located in the lumen passage; and the length of the support member is not larger than that of the push pipe. The transporting device and system have the beneficial effects that the support member is arranged in the lumen passage of the push pipe, so that the far end of the transporting device has enough gentle and agreeable properties, and the near end of the transporting device has enough supporting strength, so that the push force required by release of a lumen bracket is reduced, and the entire positioning precision of the system is improved.

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. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a conveying device and system for the above-mentioned defects in the prior art. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] A delivery device is provided, comprising a sheath tube assembly, and a handle assembly connected to the proximal e...
