摘要： 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).

摘要： A vascular dilating catheter comprising an outer tube, an inner tube and a connector, wherein said connector comprises an inlet for injecting a balloon distending solution and an inlet for insertion of a guidewire into the inner tube; the inner tube is inserted into the outer tube; and the outer tube having flexibility at a distal end side and rigidity at a proximal end side is provided with a balloon at the distal end portion thereof, the outer tube being adhered to the inner tube at the position enclosed by the balloon, and the outer tube having, between the proximal end of the balloon and the site of adhesion to the inner tube, a through-hole which connects the inner cavity of the balloon and a circular lumen formed as a gap between the outer tube and the inner tube. According to the catheter of the present invention, various forces applied to the proximal end of the catheter can be directly and positively transmitted to the distal end portion of the catheter. In addition, the distal end portion of the catheter has a suitable bending strength, and the catheter of the present invention is devoid of bending or twisting of the balloon, or snapping of the distal end portion.
摘要翻译：一种包括外管，内管和连接器的血管扩张导管，其中所述连接器包括用于注射球囊膨胀溶液的入口和用于将导丝插入内管的入口; 内管插入外管中; 并且在前端侧具有柔性的外管和在近端侧的刚性在其前端部设置有气囊，外管在由气囊包围的位置处粘附到内管，外侧在气囊的近端和与内管的粘合位置之间具有连接气囊的内腔的通孔和形成为外管和内管之间的间隙的圆形内腔的管。根据本发明的导管，施加到导管的近端的各种力可以直接和肯定地传递到导管的远端部分。此外，导管的远端部分具有合适的弯曲强度，本发明的导管没有球囊的弯曲或扭曲，或者远端部分的咬合。

摘要： A stylet which comprises a stylet assembly body and a connector for connecting the stylet to a catheter. The stylet body has a piece of wire bent double and twisted together to form a rounded end serving as a distal end at one end. The connector has a stylet connecting part for holding a proximal end of the stylet body. The connector also holds the catheter to prevent the catheter from slipping from the stylet during use.
摘要翻译：一个管心针，其包括一个探针组件本体和用于将管心针连接到导管的连接器。探针主体具有弯曲的双股线，并且扭曲在一起以形成一端作为远端的圆形端。连接器具有用于保持探针体的近端的探针连接部。连接器还保持导管，以防止导管在使用过程中从探针中滑落。
