Vascular lens-end balloon for arhythmia radiofrequency ablation

Abstract

The invention provides a vascular lens-end balloon for vascular intervention therapy. The vascular lens-end balloon comprises a balloon body, a balloon top-end electrode, balloon surrounding electrodes, balloon electrode leads and a balloon vascular lens-end interface. The balloon body is of a dual-layer structure which comprises an inner layer and an outer layer; the balloon electrode leads are connected to the balloon top-end electrode and the balloon surrounding electrodes and the balloon electrode leads can move between the inner layer and the outer layer of the balloon body; the balloon vascular lens-end interface is connected into the balloon body; both ends of the balloon vascular lens-end interface are hollowed; a spiral structure is arranged in the balloon vascular lens-end interface; balloon electrode lead interfaces are arranged at the tail end of the interior of the balloon vascular lens-end interface; and the balloon electrode lead interfaces are connected to the balloon electrode leads. The vascular lens-end balloon provided by the invention has the beneficial effects that (1) a platform is provided for endoscopic cardiovascular examination in blood vessels and for arhythmia radiofrequency ablation therapy; the influence of blood on images is eliminated; and the vascular lens-end balloon, which is unnecessary to block a blood flow, is simple and convenient to operate; and (2) the arhythmia radiofrequency ablation therapy can be conducted under the direct vision of a vascular endoscopy, so that the use of rays is reduced; therefore, the vascular lens-end balloon is simple, convenient and safe.

Description

technical field [0001] The invention discloses a blood vessel lens end balloon for arrhythmia radiofrequency ablation, which belongs to the field of medical devices, and in particular relates to a blood vessel lens end balloon for arrhythmia radio frequency ablation. Background technique [0002] Arrhythmia is a common cardiovascular disease. With the aging population in my country, the incidence of some complex arrhythmias increases accordingly; in 2014, my country's epidemiological survey showed that the prevalence of atrial fibrillation in men and women aged ≥ 60 increased to 1.83% and 1.92%, respectively; like atrial fibrillation, the prevalence of ventricular arrhythmias also increased with the level of population aging. [0003] Since the 1970s, with the clinical application of digital subtraction technology and three-dimensional cardiac imaging, as well as the development of radiofrequency medical devices and the progress of the basic theory of arrhythmia, percutaneous...

Problems solved by technology

Although the patent (United States Patent Number 4784133) that has appeared in recent years has made some improvements to the end of the vascular lens and formed a certain working platform at the head end, there are obvious defects. The problem of emptying; second, the end of the vascular lens is hard and the operation is relatively complicated; third, it is impossible to use the angioscope as the working platform to complete the interventional treatment for cardiovascular diseases
