MEDICAL TREATMENT SYSTEM AND METHOD OF USE THEREOF

A medical device includes a shaft defining a lumen and a distal portion defining a side opening in fluid communication with the lumen. The medical device includes a device coupled to the distal portion of the shaft and overlying the side opening. The device includes an expandable member configured to expand laterally outward from a collapsed state to an expanded state, and configured to allow fluid to flow through the expandable member and into the side opening. The device includes a retraction device positioned in contact with the expandable member and configured to move relative to the expandable member from a first position to a second position. When the retraction device is in the first position, the expandable member is in the collapsed state, and when the retraction device is in the second position, the expandable member is in the expanded state. 一种医疗装置包括限定腔和远侧部分的轴，所述远侧部分限定与所述腔流体连通的侧开口。所述医疗装置包括装置，其联接到所述轴的所述远侧部分并且覆盖在所述侧开口上。所述装置包括可扩张构件，其被配置为从塌缩状态横向向外扩张至扩张状态，并且被配置为允许流体流过所述可扩张构件并且进入所述侧开口。所述装置包括收缩装置，其被定位成与所述
