Abstract

The invention provides an interventional microcatheter flexible in steering, and relates to the technical field of medical instruments. The microcatheter comprises a catheter base, a stress expansion catheter and a catheter body which are sequentially connected end to end, the stress expansion catheter is arranged at one end of the catheter body in a sleeving mode and installed on the catheter base, and the catheter body comprises an inner layer, a middle layer and an outer layer which are sequentially arranged in a sleeving mode from inside to outside; and the middle layer is divided into a near end, a far end and a tip control end from near to far, and the tip control end can deform by more than 300 degrees. Due to the fact that the deformation degree of the tip control end is large, the internal structure is varied, steering is flexible when blood vessels are intervened, control over lesions in different directions in an operation is effectively enhanced, and the success rate of the operation is increased.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a flexible microcatheter. Background technique [0002] Microcatheters are used in nervous system interventional procedures to selectively deliver diagnostic materials (such as contrast agents), therapeutic devices (such as coils) or other devices or drugs to the treatment site, and are suitable for the introduction of interventional devices to assist intervention Sexual instruments penetrate deep into the neurovascular system. [0003] Existing microcatheters can only pass through common lesions. Due to the complex and changeable blood vessels involved, and the steering of the tip control end of the existing microcatheters is not flexible enough, it cannot pass through special lesions, reducing the cost of surgery. Success rate. Contents of the invention [0004] In view of this, the object of the present invention is to provide a flexible microcatheter to solve ...
