Abstract
A guide wire includes: a first core shaft made of a superelastic material, and a second core shaft made of a material more plastically deformable than the first core shaft and is joined to a distal end portion of the first core shaft. On the distal end portion to which the second core shaft is joined in the first core shaft, breaking elongation attributed to a tensile load is shorter compared to portions on a proximal end side with respect to the distal end portion.
Claims19
A guide wire comprising:
- a first core shaft made of a superelastic material;
- and
- a second core shaft made of a material more plastically deformable than the first core shaft and joined to a distal end portion of the first core shaft, wherein
- on the distal end portion to which the second core shaft is joined in the first core shaft, a breaking elongation attributed to a tensile load is shorter compared to a portion on a proximal end side with respect to the distal end portion.
1 more element
A method for manufacturing a guide wire, comprising:
- subjecting a distal end portion of a first core shaft made of a superelastic material, to first processing using at least one of pressing, swaging, and drawing;
- and
- joining a second core shaft made of a material that is more plastically deformable than the first core shaft, to the distal end portion subjected to the first processing.
