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 shaft for operating a blood thrombus capturing member (2), comprises a blood thrombus capturing member (3) equipped on the distal end side thereof, and a guide tip (4) quipped at the distal end, through which a guide wire is inserted so as to be capable of relative movement, wherein the shaft (2) is flexible. Therefore, the distal end component of a blood thrombus capturing catheter can be easily guided to a vein constriction, and particularly with a branched vein, the distal end component of the blood thrombus capturing catheter can be easily guided to the targeted branch of the vein.

摘要： It is intended to provide a thrombus-aspiration catheter capable of exerting flexibility and aspiration force even in the case where the tube in the front end side is a triple lumen tube or a contrast marker is provided at the front end. A thrombus-aspiration catheter (1) comprising a basal end side tube (2) of the double lumen type which has an aspiration lumen (11) and a core wire lumen (12), and a front end side tube (3) of the triple lumen type which has a guide wire lumen (13) in addition to the aspiration lumen (11) and the core wire lumen (12), wherein the front end of the above-described front end side tube is obliquely cut and a terminal aspiration tube (4) of a flexible double lumen, which has a front end opening (41) inclined in almost the same direction as the cut face (31), is connected to the cut face.
