Coronary balloon

The utility model provides a coronary balloon, and relates to the field of medical instruments. The coronary balloon comprises a balloon body and a guide wire arranged on the balloon body in a penetrating mode, and a channel is formed in the balloon body in a penetrating mode and used for blood circulation. The utility model aims to provide the coronary balloon which can provide a flow-through channel for blood when the coronary balloon works, so that blood flows from the near section of a blood vessel to the far position, myocardial ischemia of the far section of the blood vessel cannot be caused no matter how long the coronary balloon is blocked, and time is won for subsequent rescue. 本实用新型提出了一种冠脉球囊，涉及医疗器械领域。该冠脉球囊包括球囊主体和穿设于上述球囊主体的引导丝，上述球囊主体贯穿设置有通道，上述通道用于血液流通。本实用新型的目的在于提供一种冠脉球囊，其能够在冠脉球囊工作时为血液提供流经通道，使血流从血管近段流到远处，不管冠脉球囊堵塞多长时间均不会引起远段血管心肌缺血，为后续的抢救争取时间。
