    摘要： 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.

    摘要： It is an object to provide a filter for thrombus capture catheters with a thin wall and a sufficient strength and a method of producing the same. A filter for thrombus capture catheters is produced by a method comprising the steps of: arranging a plurality of wires so as to run helically and cross each other, thereby forming a cross wire assembly 2 with a spindle-shaped configuration, which is expanded at a middle portion 2C and converged at distal portion 2A and proximal portion 2B; and forming a parachute canopy-shaped filtering section 3 on one side of said cross wire assembly corresponding to approximately half of the spindle-shaped configuration by the dip coating method using a filter material.

    摘要： A blood flow blocking catheter, comprises: a puncture needle component having a puncture needle capable of puncturing a vein; and a sheath that covers said puncture needle component, and a balloon catheter that can be inserted into and removed from a lumen of the puncture needle component and has at its distal end a balloon that can block off blood flow. With the present invention, a balloon catheter can be easily inserted into a vein, and the balloon inflated, without making a large incision in the vein. Therefore, the temporary obstruction of blood flow with a balloon catheter can be carried out more easily, and this simplifies the surgery and makes it less invasive. Thus, it is possible to obtain a blood flow blocking catheter with which vascular anastomosis can be performed more safely and in less time.
