Abstract

The invention relates to the technical field of medical equipment, and provides a shock wave assisted drug perfusion balloon catheter and medical equipment. The shock wave assisted drug perfusion balloon catheter comprises: an outer tube; a balloon which is connected with one end of the outer tube, wherein a liquid outlet hole is formed in the side wall of the balloon; an inner tube which is sequentially inserted into the outer tube and the balloon, wherein the inner tube penetrates through the balloon, and a gap between the inner tube and the outer tube forms a medicine conveying channel; and a shock wave generator which is located in the balloon and arranged on the outer wall of the inner tube. According to the shock wave assisted medicine perfusion balloon catheter, the liquid outlet holes are formed in the surface of the balloon, and the medicine conveying channel is formed through the gap between the inner tube and the outer tube, so that external medicine can reach the balloon through the medicine conveying channel and then enter a blood vessel through the infusion hole in the surface of the balloon. The medicine loss in the conveying and withdrawing process is avoided, the medicine utilization rate is improved, and the medicine dosage and the toxicity risk can be reduced.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a shock wave-assisted drug perfusion balloon catheter and medical equipment. Background technique [0002] In recent years, drug-coated balloons have been increasingly used in the treatment of lower extremity arteriosclerosis obliterans. Drug-coated balloons are loaded with anti-intimal hyperplasia drugs, which can not only improve the short-term and long-term patency of target lesions, And can reduce the number of stent implantation. [0003] However, the existing drug-coated balloon (Drug-coated balloon, DCB) has certain limitations. On the one hand, the drug is coated on the surface of the balloon, and a large amount of drug will be lost into the blood during the delivery, expansion, and withdrawal of the balloon, which may cause distal embolism, and the drug utilization rate is low and the dose is large, which may increase the mortality rate. risk. On the other h...
