Abstract
The invention relates to an integrated thoracic aortic branch support which comprises a main support and a first branch support arranged on the sidewall of the main support, wherein the main support is communicated with the first branch support; the main support and the first branch support are composed of memory alloy wire frames and tectorial membranes fixedly coating the frames. The first branch support is arranged on the main support, a most important branch artery channel is reserved when the important arteries are coated, so as to enable the thoracic aortic support to achieve the left side of the right brachiocephalic trunk opening, the first branch support carried by the main support is placed in the left common carotid artery, or conducting bridging to the right common carotid artery and the left common carotid artery, and conducting bridging to the left common carotid artery and the left subclavian artery firstly and then covering all the arcus aortas by the support, the first support is placed in the right brachiocephalic trunk, so that the support can also be used for lesion near the aortic arch, exaggerated thoracic surgery is avoided, and the surgical risk and medical cost of a patient are decreased accordingly.
Description
Technical field
The present invention relates to medical instruments field, particularly a kind of integral type thoracic aorta branch stent.
Background technology
Along with carrying out of interventional technique, stent applications is more and more, but at present because of apparatus and technical reason, the support of some privileged sites still can not be used, and for example the artery dissection pathological changes just can't be used covered stnet near the aortic arch.Because covered stnet is applied to aortic arch, can block head to blood flow, namely cover the blood flow of left subclavian artery, left common carotid artery and right brachiocephalic trunk, cause cerebrum ischemia, cause apoplexy, in addition dead.If need to cover aortic arch with covered stnet, can only right brachiocephalic trunk be transplanted to ascending aorta by opening first breast at present, and then with right common carotid artery and left common carotid artery put up a bridge, left common carotid artery puts up a bridge to finish covered stnet with left subclavian artery again and covers aortic arch.
For above-mentioned technical barrier, need research and development and design a kind of branch stent that can accurately implant, can be applied near the pathological changes of aortic arch blood vessel, thereby avoid excessive open chest surgery, greatly reduce patient's risk and medical treatment cost.
Summary of the invention
In view of this, the purpose of this invention is to provide a kind of integral type thoracic aorta branch stent, can directly it be inserted near the aortic arch by invasive methods, with near the pathological changes of this stent applications aortic arch blood vessel, thereby avoid excessive open chest surgery, reduce patient's operation risk and medical treatment cost.
