The invention provides a transcatheter valve conveying system which comprises a handle portion, a catheter portion and a casing pipe portion. The catheter portion is connected with the handle portion, the casing pipe portion is arranged at the far end of the catheter portion and can slide relative to the handle portion, the casing pipe portion is provided with a main body portion connected with the catheter portion, and the outer surface of the at least near end of the main body portion is provided with a circumferential groove and an axial reinforcing rib connected with the circumferential groove. According to the transcatheter valve conveying system, due to the fact that the main body portion is provided with the circumferential groove and the axial reinforcing rib, the main body portion has the good bending performance, supporting strength and axial tensile performance and low axial elongation, so that the transcatheter valve conveying system can pass through the bent portion of a vessel, and a valve can be conveniently released and recycled.
Description
technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a transcatheter valve delivery system. Background technique [0002] Because transcatheter valves do not require thoracotomy like surgery, they have the advantages of less trauma and faster recovery. In recent years, as a new technology, they have been favored by doctors. Transcatheter valves are mainly delivered through a delivery system. Before implantation, the valve needs to be installed on the delivery system. During the implantation process, the valve needs to be delivered to the lesion site through the delivery system. [0003] At present, the transcatheter valve delivery system mainly includes a handle part and a catheter part. The inner core of the catheter part is the inner core for assembling the valve, and the outer part of the distal end of the catheter part is the sleeve part covering the valve; the valve needs to be released after reaching the l...
