The intracranial thrombus aspiration catheter is a device used to remove intracranial thrombi. Under the guidance of the catheter, the thrombi are aspirated to restore cerebral blood flow. The intracranial thrombus aspiration catheter is mainly composed of a catheter body and a suction device. The catheter body is generally made of flexible materials and has a moderate length. One end is connected to the suction device, and the other end is used to guide to the thrombus site.
At present, the structure of intracranial thrombus aspiration catheters used clinically is generally a four-layer design from the inside to the outside, which includes the PTFE liner inner layer, the middle metal layer, the polymer outer layer, and the hydrophilic coating on the outer surface. The structural classification of thrombus aspiration catheters is mainly divided into the proximal support section of the catheter, the middle transition section of the catheter, and the distal soft section of the catheter. The function of the proximal support section of the catheter is to have good anti-bending and support properties, and to provide good pushing performance for the catheter. The function of the middle transition section of the catheter is to have appropriate strength and flexibility to better connect the proximal support end and the distal soft section, thereby promoting the pushing force of the proximal support section to be more effectively transmitted to the distal end of the catheter. The function of the distal soft section of the catheter is to have good flexibility and a visualized Tip head, which is conducive to passing through the tortuous intracranial blood vessels.
NeuroSafe's Glutton Aspiration Catheter has the following features:
1.Hybrid structure of coil and braiding,combined flexibility and maneuverability;
2.Larger inner diameter lumen, higher aspirating efficiency;
3.Distal multi-segment design of gradual hardness;
4.Proximal composite polymer enhanced pushability;
5.Compatible with 6F long sheath;
6.Hydrophilic coating on the distal segment easily reach distal vessels/occlusions.
As a device used to remove intracranial thrombus, the intracranial thrombus aspiration catheter has the characteristics of precise guidance, good aspiration effect, safety and reliability, and easy operation. It plays an important role in neurological and cardiovascular surgery, helping patients restore cerebral blood flow and improve the effect of surgical treatment.
