Problems solved by technology

When the diameter of the balloon is smaller than the inner diameter of the blood vessel, the embolus will easily slip out of the gap between the balloon and the blood vessel, resulting in failure of thrombectomy or prolonging the operation time

Abstract

The present invention discloses an intravascular thrombus removal balloon catheter. The intravascular thrombus removal balloon catheter comprises a balloon catheter body and a thrombus removal sheath,the balloon catheter body is composed of a catheter body, a balloon and a Y-shaped catheter base, a head is arranged at a far end of the catheter body, a guide wire cavity and a balloon cavity are arranged inside the catheter body, a balloon hole is formed in an outer portion of the balloon cavity, a balloon channel and a guide wire channel are formed in the Y-shaped catheter base, and a first silica gel ring and a first cock are arranged outside the guide wire channel; a net bag is arranged at a far end of the thrombus removal sheath, a sheath tube seat is arranged at a near end of the thrombus removal sheath, the net bag is fixed at a front end of the thrombus removal sheath in a welding or bonding mode, a developing ring is arranged at a front end of the net bag, and a hole is formed in a middle of the developing ring. In the balloon catheter, rigidity of the latex balloon is improved, a certain shape can be kept in a blood vessel after the balloon is filled, slippage of the balloon is avoided, a guide wire is compatible, so that the balloon catheter can reach a farther lesion position under the guide of the guide wire.

Description

technical field [0001] The invention relates to a catheter, in particular to an intravascular embolectomy balloon catheter. Background technique [0002] The existing Fogarty embolectomy balloon catheter is a balloon catheter with a closed front end, the balloon is made of latex material, and both ends of the balloon can be visualized. After the balloon enters the target blood vessel, it is inflated to crush the thrombus in the occluded blood vessel, and the small blood clot formed after being crushed flows to the distal blood vessel along with the blood circulation, allowing it to be absorbed slowly. Larger emboli or old flocculent thrombi will be dragged out of the body along with the balloon. The cutting balloon catheter is a balloon catheter with a blade on the outer wall of the balloon that is specially used to cut the plaque tissue deposited on the blood vessel wall. It mainly benefits by squeezing the plaque and slightly dilating the blood vessel wall. [0003] The ...
