    摘要： A balloon catheter of novel configuration, which is capable of both efficiently heating a heating element by using a laser light and of ensuring durability by avoiding the laser light directly heating members other than the heating element. Provided is a balloon catheter with a balloon disposed in a distal end section of a shaft and wherein: a tightly wound coil shaped heating element is housed and arranged in the balloon; an optical fiber that irradiates a laser light inside the heating element is disposed; and a supply path that supplies a fluid to inside the balloon through an inside of the heating element and a discharge path that discharges the fluid from inside the balloon through a discharge port positioned on an outside of the heating element are disposed.

    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 suture thread for intracardiac suture operation, comprises a thread guide element (1) and a thread (2) joined to a rear end thereof, the thread guide element (1) being composed of a slender straight member (11) of a super-elastic alloy wire and a looped member (12) of a super-elastic alloy wire provided at a front end of the straight member (11). The thread guide element (1) may be further provided at its rear end with a looped member (13) of a super-elastic alloy wire. The super-elastic alloy may be an alloy selected from the group consisting of Ti-Ni, Cu-Zn-AI and Cu-AI-Ni alloys. The looped member (12) of the suture thread is captured by suture-hooking means (42) of a catheter assembly (C) including a hooking catheter (4).

    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.
