Embodiment Construction

[0032] The core of the present invention is to provide a balloon catheter that partially blocks the blood flow. By controlling the inflated state of multiple balloons respectively, the accurate adjustment of the closed state of the blood vessel is realized, thereby realizing the precise control of the perfusion blood flow, thereby promoting Restoration of brain function.

[0033] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] Please refer to figure 1 and figure 2 , figure 1 A schematic structural view of a specific embodiment of the balloon catheter provided by the present invention; figure 2 It is a schematic cross-sectional view of a specific embodiment of the balloon catheter provided by the present invention.

[0035] The specific embodiment of the present invention pr...

Abstract

The invention discloses a balloon catheter for partially blocking blood flow. The balloon catheter comprises a catheter seat and a catheter body mounted at the catheter seat, wherein a plurality of balloons are arranged on a far-end segment of the catheter body, a main hole channel and a plurality of side hole channels are formed in the catheter body, the main hole channel axially extends, and theside hole channels are isolated from another; and a main pipe and a plurality of side pipes are correspondingly arranged on the catheter seat, and the multiple side hole channels respectively communicate to different balloons and are used for respectively controlling inflation states of the multiple balloons. By inflating the multiple balloons, near-end blood vessels of a thrombus are effectivelysealed, blocked and protected to different degrees, so that early perfusion of a lot of blood flow is reduced after acute stroke is dredged, and reperfusion injury complications are reduced; by adjusting the inflation states of the multiple balloons, multi-level accurate adjustment of the sealing states of blood vessels is realized, so that accurate control of perfusion blood flow is realized, and functional recovery of the brain is promoted; and manifold auxiliary instruments do not need to be used, and blood flow retardant radiography evaluation, short-term pipe flushing and liquid perfusion during operations can be realized by virtue of the single instrument.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a balloon catheter for partially blocking blood flow. Background technique [0002] Intervention therapy is an emerging treatment method between surgery and medical treatment, after years of development. As a representative minimally invasive treatment, interventional technology for cerebrovascular diseases has developed rapidly in recent years with the advancement of imaging equipment and the introduction of new interventional devices. [0003] For the treatment of large vessel occlusion in acute ischemic stroke, mechanical thrombectomy has gradually become a bright spot in the treatment of acute ischemic stroke. Time window, the mechanical thrombectomy method is mainly divided into two types, one is the stent thrombectomy method, this method is punctured through the femoral artery, the guiding catheter system is pushed to the artery of the stroke, and then the stent device is ...
