Problems solved by technology

[0004] Due to the extremely complex anatomical structure of the left atrial appendage, the diameter of the delivery sheath used for reference is small, and during the operation, the doctor's observation field of view is limited, so in the prior art, the left atrial appendage is judged by the diameter of the delivery sheath The method of notch size has the following defects: (1) the accuracy is low, and the possibility of inappropriate device selection is high; (2) the operation is difficult and takes a long time; (3) the risk of surgery and the cost of surgery are both higher

Embodiment 1

[0064] Please also see Figure 1 to Figure 3 , the delivery system 100 provided in Embodiment 1 is used to deliver the left atrial appendage occluder to the left atrial appendage and release it. The delivery system 100 includes a delivery sheath 10, a dilation tube 20 movably accommodated in the delivery sheath 10, a pigtail catheter 30 movably accommodated in the delivery sheath 10, a hemostatic valve 40, and a hemostatic valve 40 detachably connected to the delivery sheath. The loader 50 between the tube 10 and the hemostatic valve 40 , and the push cable 60 movably accommodated in the delivery sheath 10 .

[0065] It can be understood that the dilation tube 20 can be sold as a set pre-installed in the delivery sheath 10 by the manufacturer, or the dilation tube 20 can be assembled in the delivery sheath 10 only before or during the operation by the surgeon. The loader 50 can be pre-connected between the delivery sheath tube 10 and the hemostatic valve 40 by the manufacture...

Embodiment 2

[0099] The structure of the conveying system provided in this embodiment is basically the same as that of the conveying system 100 provided in Embodiment 1. The difference is that, in the delivery system provided in this embodiment, the developing unit is provided on the second shaping section of the dilation tube, but the tube body of the delivery sheath is not provided with a developing unit, and the delivery system does not include a pigtail catheter. That is, the delivery system provided in this embodiment only includes a delivery sheath, a dilation tube, a hemostatic valve, a loader, and a push cable.

[0100] Specifically, see Figure 12 , the second shaping section of the expansion tube is provided with two developing units. And the two developing units are not in contact with each other. That is, there is a certain distance between the two developing units in the axial direction of the second shaping section of the expansion tube.

[0101] In the delivery system pro...

Abstract

The invention discloses a delivery system of a left atrial appendage occlusion device. The delivery system comprises a delivery sheath pipe. The delivery sheath pipe comprises a main body part and a shaping part which is connected to the distal end of the main body part. The shaping part comprises a first shaping section and a second shaping section which is connected to the distal end of the first shaping section. At least two developing units are arranged on the second shaping sections, and the at least two developing units keep a distance range of 10-40mm in an axial direction of the secondshaping section. The invention also discloses an application method of the delivery system in left atrial appendage occlusion. According to the delivery system provided by the invention, on the basisof a distance between the two developing units, size of a left atrial opening is measured and calculated, so that measurement accuracy is effectively improved and the possibility of improper model selection of the left atrial occlusion device is reduced; and measuring time is shortened, operating time and cost are reduced and operating risks are reduced.

Description

technical field [0001] The invention belongs to the field of interventional medical equipment and relates to a delivery system for a left atrial appendage occluder. Background technique [0002] Catheter intervention refers to a surgical method in which a doctor operates a catheter to place various materials, drugs or instruments into the heart, arteries or veins of the human body through the catheter to diagnose or treat diseases. Catheter intervention is widely used to treat a variety of cardiovascular diseases. For example, the left atrial appendage occluder is implanted in the left atrial appendage through catheter intervention to block the blood flow into the left atrial appendage, thereby eliminating the thrombus formed at the left atrial appendage due to atrial fibrillation, thereby preventing stroke or other systemic diseases caused by thrombus sexual embolism. [0003] In the prior art, the left atrial appendage occlusion operation generally first inserts a guide ...
