Microcatheters Reinforced catheters

A microcatheter is a small type of reinforced catheter, usually called a microcatheter with a diameter of 0.70-1.30 mm. Microcatheters generally consist of a tube body, a city mark, a seat, and a strain relief cannula.
Microcatheters are widely used in coronary interventional therapy, including complex lesions such as complete occlusion or subtotal occlusive lesions, bifurcation lesions, severe calcified lesions and severely distorted lesions.
The choice of microcatheter is critical to the success of neurointerventional endovascular surgery. The choice of microcatheter for endovascular therapy depends on the size of the target vessel, as well as the embolic agent used and the operator's experience. When using removable coil embolization, microcatheters with a head end bimetal marker should be used rather than a single metal marker microcatheter.
Microcatheter design features
Most microcatheters have these design features: a lubricating coating, a soft tip, and an intermediate reinforcement. Among them, the middle reinforcement layer will have a great impact on the performance of microcatheters from the design and manufacturing. The middle reinforcement layer is a design method that uses metal wire to increase the strength of the catheter and push force by weaving or winding.
At present, the microcatheters commonly used in domestic hospitals are finecross, To rnus and corsair microcatheters. Finecross microcatheter is convenient to apply, the price is favorable, the positioning is clearer, and its weave structure and small outer diameter make it have certain advantages in crossing occlusive lesions. Corsair microcatheters have a larger outer diameter to provide greater support and stability, and more stable support when reverse facing.
Microcatheters are widely used in coronary, peripheral, nerve and many more fields, and their value for interventional surgery is self-evident. Microcatheters are one-time medical consumables, which have a good reputation and market recognition in China, and sales have been very impressive. In the future, with the continuous innovation and progress of medical devices, I believe that we will have more diverse catheters to help doctors and patients better achieve the treatment of diseases.
