摘要：
The present invention relates to a catheter with a support balloon for easily passing through a blocked blood vessel, the catheter unit 100 constituting the shaft tube of the catheter； And a balloon 200 coupled to a portion of the catheter unit 100 to support the catheter unit 100 to receive a force. In addition, the present invention relates to a method using a catheter with a support balloon for easily passing through a blocked blood vessel, and more specifically, the catheter portion 100 constituting the shaft tube of the catheter； And a balloon (200) coupled to a portion of the catheter portion (100) to support the catheter portion (100) so as to receive a force, including (1) the catheter portion (100) and the balloon (200). Catheter comprising a step of inserting into the blood vessel； (2) supporting the catheter unit 100 by inflating the balloon 200 of the catheter inserted in step (1)； And (3) passing the wire through the blocked blood vessel by passing the wire through the catheter portion 100 supported in the step (2). According to the catheter attached to the support balloon for easily passing through the clogged blood vessel proposed in the present invention and a method of using the catheter, the catheter includes a balloon, thereby attempting to pass through the closed lesion on the opposite side of the closed artery. When supported, the balloon allows the wire to effectively pass through the blocked vessel without being pushed back. In addition, according to the catheter attached to the support balloon for easily passing through the clogged blood vessel proposed in the present invention and a method of using the same, the material of the balloon to be made of at least one of polyethylene, polyurethane, polyethylene terephthalate, nylon, The change in size is caused by the pressure of the injected air, and it fits well with the vessel wall and shape during the expansion process. In addition, according to the catheter with a support balloon for easily p
