Abstract: A hollow balloon catheter device (100) includes a catheter portion (10) including a passage (101) defined therethrough, and a balloon (20) located at one end of the catheter portion (10). An inflation tube (30) passes through the passage (101) and extends into a balloon element (202). A blood flow channel (201) extends through the balloon (20). The balloon (20) is inflated via the inflation tube (30) to dilate a blocked blood vessel (200), while the blood flow channel (201) forms an open configuration and communicates with the blood vessel (200) after the balloon (20) is inflated so that blood continues to flow through the blood flow channel (201). This ensures that blood flow is not hindered or blocked, eliminating concerns about blood reflux or blockage for the doctor and avoiding operational errors due to time constraints.
