1. SWIM technology.
It is a comprehensive technology that takes stent thrombectomy as the cornerstone and combines contact aspiration of the intermediate catheter to achieve the dual mechanisms of "stent grabbing" and "catheter aspiration". There are two ways to remove the stent in the SWIM technology: one is to pull the thrombectomy stent out of the intermediate catheter, and then aspirate the intermediate catheter in situ. It can be summarized as a scheme that uses the intermediate catheter as the thrombectomy channel, and the stent thrombectomy after reaching the highest position + aspiration of the intermediate catheter in situ, which is especially suitable for situations such as middle cerebral artery occlusion where the embolus load is small and can be pulled into/absorbed into the intermediate catheter. The other is that the thrombectomy stent is half-retracted into the head end of the intermediate catheter and withdrawn as a whole after locking. It can be summarized as a thrombectomy technology with double fixed clamps and combined aspiration, which is suitable for large and tough organized thrombi, such as T-shaped heavy-load thrombi at the end of the internal neck or hard thrombi that cannot be pulled into/absorbed into the intermediate catheter after repeated use of the first method.
2. ADAPT technology.
It refers to a thrombectomy method with direct aspiration as the preferred technology. In the early days, the standard operation of ADAPT was to use the suction catheter to absorb part of the thrombus, and then withdraw the suction catheter and the thrombus as a whole. However, this operation method may cause thrombus detachment and escape during the withdrawal process, and does not play the advantage of direct suction. However, the suction catheter developed later has better head-end positioning ability and larger inner cavity, providing stronger suction ability, and most thrombi can be directly sucked out of the catheter from the original position. Its standard operating procedure has also been officially changed to the current suction catheter that continues to suck negative pressure after contacting the thrombus, and sucks the thrombus out of the body in situ until the negative pressure disappears and the blood flow is unobstructed.
3. BADDASS technology.
It is a combined thrombectomy technology, that is, proximal balloon guide catheter occlusion and suction + large-cavity intermediate catheter suction + distal thrombectomy with thrombectomy stent. The standard operation of its technology requires the thrombectomy stent and intermediate catheter to be withdrawn as a whole. This technology is suitable for complex patients with large thrombus load and hard texture.
