Abstract
A balloon in which a rupture in a circumferential direction can be prevented from occurring, and a method of manufacturing the same is disclosed. The balloon is configured to be arranged on a medical catheter, and includes a dilatable cylindrical portion formed with a birefringent polymer material. A ratio of the number of orientation distributions, calculated by dividing the number of orientation distributions of the cylindrical portion in a circumferential direction by the number of orientation distributions of the cylindrical portion in an axial direction, is less than 2.

A balloon configured to be arranged on a medical catheter, comprising:
- a dilatable cylindrical portion that is formed with a birefringent polymer material,
- the dilatable cylindrical portion being configured such that a ratio of a number of orientation distributions calculated by dividing a number of orientation distributions throughout a total length of the cylindrical portion in a circumferential direction by a number of orientation distributions throughout a total length of the cylindrical portion in an axial direction is less than 2, whereby a rupture of the dilatable cylindrical portion in the circumferential direction is prevented.
