Embodiment 1
[0047] If the stent of the present invention is used as an acute thrombus removal device, the doctor slowly pushes the catheter (or microcatheter) with the stent 10 inside to pass through the thrombus 30, and then presses the proximal end 21 of the delivery guide wire 20 fixed together with the stent, Withdraw the microcatheter slowly, as image 3 As shown, the stent is released and contains the thrombus 30 like this. At this time, the delivery guide wire 20 is slowly withdrawn, and finally the thrombus is sent to a guide catheter with a larger inner diameter, and the guide catheter with thrombus is withdrawn from the patient's body. The patient's blood flow was unblocked and the symptoms were relieved.
Embodiment 2
[0049] If the stent of the present invention is used as a temporary stent to quickly dredge narrow or blocked blood vessels, such as Figure 4 As shown, the doctor can send the microcatheter equipped with the stent 10 of the present invention to the more distal position of the narrowed or blocked blood vessel 40, then press the delivery guide wire 20 fixed with the stent, and slowly withdraw the microcatheter , so that the bracket is released. If the doctor is not satisfied with the position of the stent, he can withdraw the stent to the microcatheter, readjust the position of the microcatheter, and then release the stent again, and finally place the middle part of the stent on the narrowed blood vessel. Due to the expansion and support of the stent, the actual inner diameter of the narrowed blood vessel increases. Blood flow gradually increased, and the patient's symptoms eased. Generally, blood flow can be fully restored after about 30 minutes to 120 minutes. After achievi...
Embodiment 3
[0053] If the stent of the present invention is used as a permanent implant stent 10 to assist in releasing the microcoil, the doctor can send the microcatheter with the stent of the present invention inside the bifurcation aneurysm 50 of the main blood vessel 70 and branch blood vessels 71, and then Press and hold the delivery guide wire 20 that is fixed together with the stent, and slowly retract the microcatheter, so that the stent is released, such as Figure 5 , by observing the position of the development ring (or development coil) 15 at the distal end of the stent 11, it is ensured that the umbrella-shaped (or barrel-shaped) structure at the distal end of the stent is just positioned at the neck of the aneurysm 50. If the doctor is dissatisfied with the position of the stent, the stent can be withdrawn into the microcatheter, the position of the microcatheter is readjusted, and then the stent is released again. Finally, the umbrella (or barrel) structure at the distal en...
