Embodiment approach

[0043] see figure 2 , figure 2 It is the second embodiment of the blood flow inlet hole 123 and the blood flow outlet hole 122 in the present invention. The blood flow inlet hole 123 and the blood flow outlet hole 122 are arranged in a groove shape, that is, dense holes, and the holes communicate with each other to form a complete The open area, that is, grooves are made in the guide wire lumen, so that blood enters the guide wire lumen through the slot-like opening.

[0044] In addition, the outer diameter of the guide wire 4 described in the present invention can also be set to a gradual change type, or the inner diameters of the guide wire lumen 1 111 and the guide wire lumen 2 15 can be set to a gradual change type, or the guide wire and the guide wire lumen The gap fit in the gap controls the blood flow into its gap, which in turn controls the blood flow.

[0045] The following is an example of aneurysm occlusion in complex intracranial parts (such as Figure 5 Shown...

Abstract

The present invention discloses a balloon catheter capable of controlling blocking amount of blood flow. The balloon catheter capable of controlling blocking amount of blood flow comprises a balloon catheter body and a guide wire, the balloon catheter body is composed of a catheter body, a balloon and a Y-shaped catheter base, a front end of the guide wire is provided with a head end and a springring, the catheter body is composed of a flexible far-end section, a balloon section and a rigid pushing shaft section, a first guide wire cavity is formed in the flexible far-end section, a developing mark ring is further arranged at one end, close to the rigid pushing shaft section, of the balloon section, and a balloon channel and a guide wire channel are formed in the Y-shaped catheter base. The balloon catheter capable of controlling blocking amount of blood flow can adapt to a long operation time, can properly open a vascular access, control blood flow, avoid ischemia or metabolic disorders of downstream organs and improve a survival rate of patients in an operation of blocking an aneurysm or a blood vessel for a long time. Besides, due to a multi-cavity structure, the guide wire cavity and the balloon cavity are independent of one another, positions of the catheter and the guide wire can be flexibly adjusted during a balloon-filling period, operation of an operator is facilitated, and operation time is shortened.

Description

technical field [0001] The invention relates to a catheter used in surgical operations, in particular to a balloon catheter with a controllable blood flow blocking amount. Background technique [0002] The existing occlusion balloon catheter system is a set product consisting of a occlusion balloon catheter and a 0.010-inch hydrophilic guide wire. The occlusion balloon catheter is a single-lumen tapered multi-purpose catheter with a hydrophilic coating; the distal end has a non-detachable, low-pressure inflated, highly compliant balloon with two radiopaque markers bring. There is an overflow port at the front end of the catheter, and the balloon can only be inflated when the overflow port is blocked by the guide wire. The overflow port is made of heat-shrinkable polyester elastomer; the proximal and distal ends of the catheter are respectively made of modified nylon and polyene elastomer; the catheter lining is made of polytetrafluoroethylene; the balloon is made of Made ...
