Abstract
A medical device shaft includes a specific portion having a flattening of 2% or more and 6% or less, the flattening being defined as a value obtained by dividing a difference between an orthogonal diameter and a minimum diameter by the orthogonal diameter, where, in a cross-section orthogonal to an axial direction of the medical device shaft, a diameter having a smallest length is defined as the minimum diameter and a diameter in a direction orthogonal to a direction of the minimum diameter in the cross-section is defined as the orthogonal diameter.
Claims15
A medical device shaft comprising:
- a specific portion having a flattening of 2% or more and 6% or less, wherein
- the flattening is defined as a value obtained by dividing a difference between an orthogonal diameter and a minimum diameter by the orthogonal diameter, and
- in a cross-section orthogonal to an axial direction of the medical device shaft, a diameter having a smallest length is defined as the minimum diameter and a diameter in a direction orthogonal to a direction of the minimum diameter in the cross-section is defined as the orthogonal diameter.
guidewire comprising:
- a coil body formed by winding a wire;
- and
- a core shaft inserted into the coil body, the core shaft including:
- a distal end side specific portion having a flattening of 7% or more;
- and
- a specific portion located proximal to the distal end side specific portion, the specific portion having a flattening of 2% or more and 6% or less,
- wherein the flattening is defined as a value obtained by dividing a difference between an orthogonal diameter and a minimum diameter by the orthogonal diameter.
