A sheath unit for recovering a thrombus capture member, in which the thrombus capture member can be accommodated without leakage of a thrombus, and which can be more smoothly passed through a lesion, and a thrombus capture catheter unit for capturing the freed thrombus are provided. The sheath unit for recovering a thrombus capture member includes a sheath having a flexible tube at its tip, a portion of the flexible tube being reduced in diameter. A thrombus capture catheter unit includes the sheath unit for recovering the thrombus capture member and a thrombus capture member. The thrombus capture member which is expanded is accommodated into the sheath and a crossed wire member and a portion of a filter part constituting the thrombus capture member are accommodated in the flexible tube, thereby diameter-reducing an opening part of the filter part.
