Abstract
A method for manufacturing a stent delivery system that includes a first diameter reduction step including a first compression step of compressing a stent inward in a radial direction of the stent in a state where a balloon is inserted into a tube of the stent formed in a tubular shape to reduce diameters of the stent and the balloon, and a first release step of releasing the compression thereafter. A pressurization step of supplying fluid to the balloon to inflate the balloon and pressing the balloon against the inner side of the stent is performed during the first release step or after the first release step.

A method for manufacturing a stent delivery system, the method comprising:
- a first diameter reduction step including a first compression step of compressing a stent inward in a radial direction of the stent in a state where a balloon is inserted into a tube of the stent formed in a tubular shape to reduce diameters of the stent and the balloon, and a first release step of releasing the compression after the first compression step;
- a pressurization step of supplying fluid to the balloon to inflate the balloon and pressing the balloon against an inner side of the stent, wherein the pressurization step is performed during or after the first release step;
- and
- a second diameter reduction step performed after the first diameter reduction step, the second diameter reduction step including a second compression step of compressing the stent inward in the radial direction of the stent to reduce the diameters of the stent and the balloon, and a second release step of releasing the compression after the second compression step, wherein the pressurization step is performed during the second compression step.
A method for manufacturing a stent delivery system, the method comprising:
- compressing a stent inward a first time in a radial direction of the stent in a state where a balloon is inserted into a tube of the stent formed in a tubular shape to reduce diameters of the stent and the balloon, and releasing the compression after the compressing of the stent inward the first time;
- compressing the stent inward a second time in the radial direction of the stent to reduce the diameters of the stent and the balloon, and releasing of the compression of the stent after the compressing of the stent inward the second time;
- and
- supplying fluid to the balloon to inflate the balloon and press the balloon against an inner side of the stent.
A method for manufacturing a stent delivery system, the method comprising:
- compressing a stent inward at a load of 5 N to 10 N per length of 1 mm in an axial direction of the stent inward in a radial direction of the stent in a state where a balloon is inserted into a tube of the stent formed in a tubular shape to reduce diameters of the stent and the balloon;
- releasing the compression after the compressing of the stent;
- and
- supplying fluid to the balloon to inflate the balloon and press the balloon against an inner side of the stent.
