A guide wire includes a wire having an elongated body section and a distal portion decreasing in outer diameter from the body section. The guide wire may have a resin coating portion coating the body section and the distal portion and having a smooth outer surface; and a visually discernible mark provided at the resin coating portion. The body section may have a flexible portion which constitutes a part of the body section and lower in flexural rigidity than other portions of the body section different from the part, and the visually discernible mark is provided at a position of the resin coating portion at which the flexible portion is coated with the resin coating portion

A medical instrument to be inserted into a living body before being used. The medical instrument is provided with a medical instrument main body including a long linear body having flexibility on which a coating layer covering at least the outer periphery on the distal side thereof is formed. The coating layer composes of a first layer which includes a material containing a low-friction resin material capable of lowering friction and a binder resin material serving as a binder; a second layer which is formed on the first layer and includes a material containing a low-friction resin material and a pigment and in which the content of a binder resin material is lower than the binder resin material content of the first layer or nil; and a third layer which is formed on the second layer and includes a material containing a low-friction resin material.

A guide wire includes a member with a core wire. The guide wire may have a marker-forming layer which partly encircles the outer surface of the member and differs in color from the member, and a coating layer which covers the marker-forming layer and the member at least in the region where the marker-forming layer is formed and has such transparency as to make the marker-forming layer visible. The marker-forming layer and the coating layer can be formed from mutually miscible resins, while the marker-forming layer functions as a visible marker.

A guide wire includes a wire body having a core wire and a resin coating layer covering an outer periphery of a distal section of the wire body, and an annular member provided on the proximal side of the resin coating layer. The outer diameter of the distal end of the annular member and the outer diameter of the proximal end of the resin coating layer are preferably equal, and a distal end face of the annular member is joined to a proximal end face of the resin coating layer.

The invention includes: an operation wire which is inserted into a catheter, and is supported on a distal end or the vicinity of the catheter; and an operation portion which moves the operation wire back and forth with respect to the catheter. The catheter is provided with a curvable portion wherein the distal direction of the catheter is curved with respect to the proximal direction of the catheter.

A guide wire includes an elongate wire body, and a marker at least at a distal-side portion of the wire body over the whole circumference to indicate the intracorporeal position of the wire body. The marker has a first line-forming portion and a second line-forming portion which intersect each other at a plurality of locations so that the marker has a grid-like shape as a whole. According to another aspect, a guide wire includes a member with a core wire, a marker-forming layer partly encircling the outer surface of the member and differing in color from the member, and a coating layer covering the marker-forming layer and the member at least in the marker-forming layer region and having transparency making the marker-forming layer visible. The marker-forming and coating layers can be formed from mutually miscible resins, while the marker-forming layer functions as a visible marker.

摘要:
A guide wire includes an elongated wire body and a radiopaque part capable of forming an X-ray image and located at the distal end portion of the wire body. The radiopaque part has a radiopaque member and a resin coating layer. The radiopaque member is composed of a metallic material capable of forming an X-ray image and arranged outside the wire body and in the lengthwise direction of the wire body. The resin coating layer covers the radiopaque member and at least part of coating layer contains a radiopaque material capable of forming an X-ray image. The radiopaque part is divided into a first radiopaque region, a second radiopaque region, and a third radiopaque region which are sequentially arranged from the distal end in the lengthwise direction of the wire body.
