Example Embodiment

[0057] Example one

[0058] figure 1 It is a schematic structural diagram of a valve installed in the transcatheter heart valve pre-installation system provided by Embodiment 1 of the present invention. figure 2 It is a side view structure diagram of the protective device of the transcatheter heart valve preinstallation system provided in the first embodiment of the present invention. Reference Figure 1 to Figure 2 As shown, this embodiment provides a transcatheter heart valve preinstallation system.

[0059] The transcatheter heart valve pre-installation system includes: a delivery system 1 including a catheter 11 for inserting a valve 3 and an operating handle (not shown in the figure). Among them, the catheter 11 can realize the delivery of the valve 3 in the human body. In order to reduce the damage to blood vessels in the process of implanting the valve 3 into the human body. The diameter of the catheter 11 is as small as possible, and is generally smaller than the inner d...

Abstract

The present invention provides a transcatheter cardiac valve pre-assembly system and pre-assembly method. The system comprises a delivery system and a protective device. The delivery system includes acatheter for loading valves, the protective device is provided with a cavity in communication with the catheter, the cavity is used for accommodating at least a portion of the valves that are not taken by the catheter and the cavity has at least one opening. According to the invention, when the valve is pre-assembled with the delivery system catheter, the part of the valves that are not taken bythe catheter is protected by the protective device, the part of the valves outside of the catheter is prevented from being deformed or damaged due to the collision or extrusion, and the normal function of the valves is ensured, and the service life of the valves is prolonged.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a transcatheter heart valve preinstallation system and a preinstallation method. Background technique [0002] Currently, transcatheter heart valves on the market are usually assembled and connected to the delivery system during the operation. Due to the difficulty in the assembly process, especially in the stage of locking the valve frame of the valve with the catheter of the delivery system, it needs to go through Professional training and a lot of practice can only be mastered. This process not only increases the workload of doctors, but also prolongs the preparation time for surgery. [0003] The existing technology completes the assembly of the valve and the delivery system when the product is manufactured, that is, the valve has been completely put into the catheter of the delivery system when it leaves the factory, and the entire valve is compressed in the catheter...
