Problems solved by technology

[0004] The embodiment of this specification provides a detachable balloon catheter, which is used to solve the following technical problems: the reflux of the embolic agent cannot be controlled. Once the embolic agent reflux exceeds its release point, it will still cause microcatheter incarceration, resulting in difficulty in removing the catheter or even unable to withdraw

Abstract

The embodiment of the invention discloses a detachable balloon catheter, and belongs to the field of medical instruments. The detachable balloon catheter comprises: a Y-shaped valve, wherein the Y-shaped valve comprises a Y-shaped valve main path and a Y-shaped valve bypass; a balloon catheter which is a coaxial double-cavity balloon catheter and comprises a balloon catheter outer cavity and a balloon catheter inner cavity, wherein the near end of the balloon catheter is connected with the Y-shaped valve; a detachable head end catheter, wherein a developing marking ring is arranged at the tail end of the detachable head end catheter; and a damping sleeve which is used for releasing and separating the balloon catheter from the detachable head end catheter. According to the detachable balloon catheter provided by the embodiment of the specification, the detachable head end catheter can be detached, so that an embolism agent can be better filled into a lesion part, the embolism effect of the lesion part is better, the surgical risk is reduced, and the surgical cure rate is increased.

Description

technical field [0001] This specification relates to the field of medical devices, in particular to a detachable balloon catheter. Background technique [0002] Endovascular interventional embolization is currently the safest and most effective method for the treatment of cerebral arteriovenous malformations. Endovascular interventional embolization technology is to obtain vascular access through arterial or venous puncture, use guide wires, catheters and other instruments to enter the malformed lesion, and then inject liquid embolism through a microcatheter to seal the lesion, so as to achieve the purpose of treatment. During the embolization process, a small amount of embolic agent usually needs to flow back to block the proximal supplying artery, so as to ensure better diffusion of the embolic agent to the target site. However, the reflux of embolic agents has many risks. The reflux enters the blood supply artery of normal brain tissue, causing cerebral infarction, and t...
