摘要：
An intravascular guide wire (20) having at least two core materials joined together. There is a wire core (22) having a proximal core section (24) with a proximal end (26) and a distal end (28) and a distal core section (30) with a proximal end (32) and a distal end (34). The distal end (28) of the proximal core section (24) and the proximal end (32) of the distal core section (30) are formed into complementary shapes, and then placed into a flexible sleeve (56) in opposing directions. Inside the flexible sleeve, the complementary shaped ends are joined together through bonding, welding, brazing, cementing, or soldering. The flexible sleeve can be either a stretched coil or a polyimide sleeve, each with an outer diameter similar to the outer diameter of the core wire, therefore the guide wire does not require additional grinding to reduce the outer diameter of the joined section.
摘要（中）：
具有连接在一起的至少两个芯材料的血管内导丝（20）。 存在具有近端芯部分（24）的线芯（22），其具有近端（26）和远端（28）以及具有近端（32）和远端（32）的远端芯部分（30） 34）。 近端芯部分（24）的远端（28）和远端芯部分（30）的近端（32）形成互补形状，然后在相反的方向上放置在柔性套筒（56）中。 在柔性套筒的内部，互补的端部通过粘合，焊接，钎焊，胶结或焊接而连接在一起。 柔性套筒可以是拉伸线圈或聚酰亚胺套筒，每一个具有类似于芯线的外径的外径，因此导丝线不需要额外的研磨以减小接合部分的外径。
