Description
Technical Field
The invention relates to the field of medical instruments, in particular to an intracapsular turbulence device.
Background
Intravascular devices such as catheters are often used in the medical field. Catheters are typically inserted into a patient's femoral, radial, carotid, or jugular vein and pass through the patient's blood vessels to the heart, brain, or other target anatomy. Typically, the guidewire is first directed to the target anatomy, and one or more catheters are then passed through the guidewire and directed to the target anatomy. Once in place, the catheter can be used to deliver drugs, stents, embolic devices, radiopaque dyes, or other devices or substances for treating a patient in a desired manner. In other cases, the catheter and guidewire are simultaneously delivered toward the target anatomy while the guidewire is within the catheter, and then the guidewire is further delivered into the anatomy by translating within the catheter.
Aneurysms are hemangioid projections that result from abnormal changes in the local blood vessels of the arteries. Subarachnoid hemorrhage due to rupture of aneurysms is often associated with very high mortality rates. Patients may be life threatening at any time if the aneurysm does not have a good treatment. The intracapsular spoiler device is currently a mesh device configured to fully deploy within the aneurysm, with the interstices of the mesh covering the neck of the aneurysm and reconstructing the aneurysm-carrying blood vessel interface. The intracapsular spoiler device can be used to treat wide-neck aneurysms and aneurysmal ruptures. Since the intracapsular spoiler device is fully placed within the aneurysm, the tumor-bearing and branched blood vessels are unobstructed and can be accessed during treatment for any further retreatment or subsequent deployment of the auxiliary device. The prior art spherical or spheroid-like intracapsular spoiler devices have the following problems: residual blood flow in the intracapsular spoiler device; poor developing property, and can not judge the covering effect of the tumor neck; the model is limited and can not adapt to aneurysms or wide neck aneurysms with various forms. The wide carotid aneurysm, which is only suitable for the bifurcation of the blood vessel, cannot be treated for most sidewall type aneurysms.
The invention aims to provide a novel intracapsular spoiler device which can solve the problems of the existing intracapsular spoiler device.
