Abstract: The disclosed medical device has high visibility on non-woven fabric having a color such as green, blue, or the like, excellent identifiability from other medical devices having colors such as green, blue, or the like, and also a high adhesion property and strength of a coating. The medical device comprises an elongated body and a resin layer covering at least a proximal portion of the elongated body. The resin layer is comprised of a first layer which includes a first fluororesin, an organic pigment and titanium oxide, and a second layer which is formed on the first layer and includes a second fluororesin.

Abstract: The disclosed medical device has high visibility on non-woven fabric having a color such as green, blue, or the like, excellent identifiability from other medical devices having a color such as green, blue, or the like, and high surface smoothness. The medical device comprises an elongated body and a resin layer for covering at least a proximal portion of the elongated body, in which the resin layer has a first layer which includes a first fluororesin, titanium oxide, and a dispersant, and a second layer which is formed on the first layer and includes a second fluororesin. The content of the titanium oxide is 30% by weight or more relative to the solid content of the first layer, and an acid value of the dispersant is 20 to 90 mg/KOH.

Abstract: Provided is an improved medical elongated body which can be inserted into a biological lumen and can be restrained from unintentionally moving at a target site inside the biological lumen. The medical elongated body includes a main body portion that extends in an axial direction, and a projection portion that protrudes radially outward on an outer circumference of the main body portion and extends in the axial direction. One surface of the projection portion in a circumferential direction has higher sliding properties than an other surface of the projection portion in the circumferential direction.

Abstract: A cover application device makes it possible to easily impart desired slidability to a medical elongated body by putting a cover portion on a distal portion of a guide wire. The cover application device has the cover portion that is to be put on the distal portion of the guide wire, and an attachment tool having a lumen into which the guide wire is insertable and having an outer peripheral surface covered with the cover portion.
