Abstract

The present invention provides an intracapsular spoiler device comprising a plurality of blades, a plurality of tip filaments each extending through a tip from a root of a respective blade, a top developing ring secured to the top developing ring, a lower developing ring secured to the root of the plurality of blades, and a movable developing ring secured to the tip of the tip filaments. And each blade is arranged on the corresponding blade tip wire through the corresponding movable developing ring and can slide on the corresponding blade tip wire. The vein net of the intracapsular turbulent flow device is located in the aneurysm neck opening and attached to the aneurysm neck opening, complete filling of the aneurysm or adding of a spring ring for assistance is not needed, the space occupying effect is reduced, compared with a traditional treatment mode, intravascular operation is reduced, stent type objects do not need to be implanted into the aneurysm carrying artery, and the treatment cost is reduced. The occurrence probability of thrombus events in the operation period is reduced, meanwhile, a patient does not need to take double-antibody drugs after treatment, and safety is improved.

Description

technical field

[0001] The invention relates to the field of medical devices, in particular to an intrasaccular spoiler. Background technique

[0002] Intravascular devices such as catheters are frequently used in the medical field. Catheters are typically inserted into a patient's femoral artery, radial artery, carotid artery, or jugular vein and passed through the patient's blood vessels to reach the heart, brain, or other target anatomy. Typically, a guidewire is first guided to the target anatomy, and one or more catheters are then passed over the guidewire and guided to the target anatomy. Once in place, the catheter may be used to deliver drugs, stents, embolic devices, radiopaque dyes, or other devices or substances used to treat the patient in the 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 delivered further into the anatomy by...
