| titleOfInvention | A microcatheter with changing outer diameter |
| abstract | The utility model discloses a micro-catheter with changing outer diameter, which comprises a distal-end catheter section with variable diameter and a proximal-end catheter section connected with the distal-end catheter section. It includes an outer layer, an elastic metal layer arranged inside the outer layer, an inner layer arranged inside the metal layer, the distal catheter segment has a developing ring near the head end, and the head end of the distal catheter segment is provided with a chamfer. The device is provided with a spring layer and a braided layer outside the spring layer on the proximal catheter segment, so that the diameter and hardness of the proximal catheter segment are larger than those of the distal catheter segment, so that the entire catheter can more easily enter deeper and thinner blood vessels, and at the same time By changing the material of the catheter, setting a gain coating on the outer layer of the catheter, and changing the overall hardness, compared with the current microcatheter, the stimulation to the blood vessel can be reduced, the catheter can be promoted into the deep blood vessel, and the catheter can be reduced. The occurrence of other problems is conducive to the withdrawal of the catheter. |
