ABSTRACT:
A catheter assembly for intracardiac suture comprises a hooking catheter (4) provided at a distal end with a suture-hooking member (42) and at the proximal end with a manipulating element (41) at a proximal end thereof; a first sheath (3) for movably holding the hooking catheter therein; a piercing catheter (2) for movably holding the first sheath, provided at a distal end with a piercing needle and at the proximal end with a hemostatic valve 29; and a second sheath (1) for movably holding the piercing catheter, provided at the proximal end with a hemostatic valve 19. The piercing catheter (2) and second sheath (1) are provided at each distal portion with a side hole (21, 11) so that the side hole (21) of the piercing catheter (2) is laid to lie the side hole (11) of the second sheath (1) when the tip of the piercing catheter (2) is reached to the tip of the second sheath to allow the first sheath (3) to protrude through the overlapped side holes (21, 11).
