Abstract
An applicator for applying an external counterpulsation to a body portion is provided. The applicator including: an outer shell for covering the body portion, the outer shell having a length in a longitudinal direction and a circumference in a circumferential direction; a balloon disposed in the outer shell, pressurization of which applies an external pressure to the body portion; and at least one anti-deformation member for reducing an amount of deformation of the outer shell caused by the pressurization of the balloon.

- and
- at least one anti-deformation member for reducing an amount of deformation of the outer shell caused by the pressurization of the balloon.
A method for applying an external counterpulsation to a body portion, the method comprising:
- covering the body portion with an outer shell, the outer shell having a length in a longitudinal direction and a circumference in a circumferential direction;
- disposing a balloon in the outer shell;
- pressurizing the balloon to apply an external pressure to the-body portion;
- and
- disposing at least one anti-deformation member in or on the outer shell for reducing an amount of deformation of the outer shell caused by the pressurization of the balloon.
