Problems solved by technology

However, the top structure of this kind of device brings greater impact to the weak top of the aneurysm, and its protruding part at the proximal end interferes with the blood flow to a certain extent because it falls into the parent vessel

Embodiment 1

[0029] Embodiment 1: Embolization of arterial non-side wall aneurysms using a braided body system. Such as Figure 1 to Figure 9 As shown, a new type of braid system for embolization of aneurysms, including a mesh braid 1, a delivery system 2 connected to the braid, and a ring of polymer material placed between the braid and the delivery guide wire 3. Glue 4 for bonding, and a sheath 5 for compressing the braid. The microcatheter 6 enters the lesion 7 of the aneurysm, and then the entire braided body system advances in the lumen of the microcatheter 6 until its distal end reaches the ostium of the aneurysm. Keep the sheath tube 5 still, and push the delivery system 2 forward, so that the braid 1 gradually moves into the aneurysm. During this process, the braid will continue to expand automatically. As the entire braid 1 is pushed out of the sheath 5 , the braid 1 will be completely released within the aneurysm 7 . Then the release instrument 8 connected to the proximal end...

Embodiment 2

[0030] Embodiment two: if Figure 11 As shown, for the use of the sheath, it can also be used only as a transition tool for the braid in the compressed state to enter the microcatheter. Such as Figures 12 to 14 As shown, in this case, the sheath only needs to enter the handle portion of the microcatheter, and the braid in the compressed state will advance directly in the lumen of the microcatheter. The subsequent release process is the same as the release process in Embodiment 1, and will not be repeated here.

Embodiment 3

[0031] Embodiment 3: Embolization of arterial side wall aneurysms by using braided body system. Such as Figure 15 As shown, the embolization of arterial side wall aneurysms using the braid system is basically similar to the embolization of non-side wall aneurysms, and will not be repeated here.

Abstract

The invention discloses a novel braided part system for embolizing aneurysm and belongs to the field of medical instruments. The braided part system comprises a mesh braided part and a delivery system connected with the braided part. During an operation, a doctor can send the braided part to an aneurysm portion by a microcatheter and a sheath, the braided part which is compressed originally is pushed gradually and released into the aneurysm portion, and then is separated from the delivery system by an electric detaching manner or other detaching manners, the delivery system and the sheath are removed to the outside of the body of a patient, and the braided part is remained in the aneurysm portion as an embolism. The braided part system can embolize the aneurysm portion effectively, requirements to personal embolizing skills of the doctor in operation are lowered, operation time is shortened, impact to the top of the aneurysm is lowered, interference to blood flow in tumor-carried blood vessels is decreased, and clinical effects of aneurysm embolism is improved further.

Description

technical field [0001] The present invention relates to a medical device, and more particularly, the present invention relates to a novel braid system for embolizing aneurysms. Background technique [0002] Aneurysm is a common vascular disease. At present, regarding how to treat aneurysms, clinical doctors can use aneurysm clips to occlude the neck of the aneurysm, bypass and use coils to embolize the aneurysm. Due to the use of the two surgical methods of aneurysm clipping to occlude the neck of the aneurysm and bypass, it is necessary to directly open the body cavity that wraps the aneurysm, such as craniotomy and thoracotomy, which inevitably brings a lot of pain to the patient. Injury, at the same time, the wound recovery period of patients in this type of operation is also longer. Therefore, clinically doctors tend to use coils to embolize aneurysms. However, using coils to embolize aneurysms often requires doctors to have quite skilled coil packing skills, and for ...
