implant system

Abstract

The invention discloses an implant system, which includes a delivery tube, a grabber and a guide wire. The delivery tube has a proximal end surface and a distal end surface oppositely arranged, and a side peripheral surface connecting the proximal end surface and the distal end surface. There are a first wire passing hole and a second wire passing hole, the catcher is passed through the first wire passing hole, and the guide wire is passed through the second wire passing hole; the first wire passing hole runs through the proximal surface and the far end surface; the second wire hole includes a first section and a second section, the first section communicates with the second section, and the proximal opening of the first section is set on the proximal surface, and the distal opening of the second section is set on the side On the peripheral surface, the second section is far away from the first wire passing hole and extends toward the distal end; the central axis of the second section forms a certain angle with the central axis of the first section. Since the catcher threaded in the first wire passing hole can adjust the angle of the short branch, the guide wire protruding from the second wire passing hole can smoothly enter the lumen of the bending part along the axial direction of the bending part for subsequent implantation of extended stents.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an implant system. Background technique [0002] For the treatment of abdominal aortic aneurysms, abdominal aortic stent grafts are usually used to isolate the tumor in the abdominal aorta. If the tumor accumulates in the left common iliac artery, an extended stent must be implanted to separate it from the abdominal aorta. The stent-graft was connected such that the extended stent isolated the tumor in the left common iliac artery. Generally, an abdominal aortic stent graft includes tubular long branches and short branches. During the implantation of the extended stent, a guide wire is usually used to first pass through the left common iliac artery and then enter into the lumen of the short branch, and then the extended stent is implanted along the guide wire and connected to the short branch. However, if the cavity of the abdominal aortic aneurysm where the abdomin...

AI Technical Summary

Problems solved by technology

However, if the cavity of the abdominal aortic aneurysm where the abdominal aortic aneurysm is located is large, the relative angle between the short branch and the left common iliac artery is large, or the relative angle between the long branch and the short branch is large (for example, the apex of the aneurysm is between the two branches) In the middle), the guide wire protruding from the left common iliac artery is difficult to align with the end of the short branch, which in turn makes it difficult to extend the guide wire into the short branch, and finally makes it difficult to implant the extended stent
