Abstract

The invention provides a double-sacculus conduit for thrombolysis, comprising a connecting device, a stress diffusion tube, a pushing rod, sacculuses, a conduit top section, an inner tube and a guide wire. The pushing rod is of a hollow structure; the inner tube passes through an inner cavity of the pushing rod and inner cavities of the sacculuses; a far end of the inner tube is fixed with the conduit top section; and the connecting device is provided with a first connector and a second connector. The sacculuses are of a double-sacculus structure and comprise a first sacculus, a second sacculus, a connection conduit tube section which is used for communicating the first sacculus with the second sacculus; the sacculuses are provided with micro-pores so that the first sacculus and the second sacculus can be expanded to form a sealed treating space between the first sacculus and the second sacculus when liquid medicine is introduced into the second connector; and the liquid medicine can enter the sealed treating space through the micro-pores. According to the double-sacculus conduit for the thrombolysis, the medicine feeding efficiency of medicaments can be improved.

Description

technical field [0001] The invention relates to a double-balloon catheter for thrombolysis. Background technique [0002] Vascular embolism is a common disease in cardiovascular diseases, such as cerebrovascular ischemic stroke, etc., and its disability rate and mortality rate are extremely high. At present, the treatment methods for such diseases mainly include drug thrombolysis and mechanical thrombectomy. [0003] Judging from the effect of current clinical treatment, the effects of drug thrombolysis and mechanical thrombectomy are not very satisfactory. [0004] The main problem with drug thrombolysis is the need for systemic administration, which can easily lead to bleeding complications. And in the process of thrombolysis, after the size of the embolus shrinks, it is easy to block the blood vessel with smaller diameter downstream. [0005] The main problem of mechanical thrombectomy is that it is easy to destroy the emboli when the grabber captures the emboli, resul...
