Abstract
Official abstract text for this publication.
A guide wire including a core shaft including a distal end portion having a pseudoelastic property, a tip joined to a distal end of the distal end portion of the core shaft, and an auxiliary wire that is arranged parallel to the distal end portion of the core shaft. The auxiliary wire has a distal end joined to the tip and a rear end joined to the core shaft. The auxiliary wire has a high flexibility, a high breaking strength, and a short breaking elongation compared to the distal end portion of the core shaft.
First claim
Opening claim text (preview).
The invention claimed is: 1 . A guide wire comprising: a core shaft including a distal end portion having a pseudoelastic property; a tip joined to a distal end of the distal end portion of the core shaft; and an auxiliary wire arranged parallel to the distal end portion of the core shaft, the auxiliary wire having a distal end joined to the tip and a rear end joined to the core shaft, wherein the auxiliary wire is more flexible than the distal end portion of the core shaft, a breaking strength of the auxiliary wire is higher than a breaking strength of the distal end portion of the core shaft, a breaking elongation of the auxiliary wire is shorter than a breaking elongation of the distal end portion of the core shaft, and the breaking elongation of the auxiliary wire is shorter than an elongation at a yield point of the distal end portion of the core shaft. 2 . The guide wire according to claim 1 , wherein the auxiliary wire comprises a plurality of strands twisted together. 3 . The guide wire according to claim 1 , wherein the pseudoelastic property is an elastic property that occurs in a mechanism other than elasticity resulting from changes in interatomic spacing. 4 . The guide wire according to claim 1 , wherein the pseudoelastic property is at least one of transformation pseudoelasticity and twinning pseudoelasticity.
