| 摘要 |
A spacer and implant assembly are disclosed, the spacer including an outer balloon that is folded so as to be dilatable, and an inner balloon that is folded so as to be dilatable, and that is removably inserted into the outer balloon. The inner balloon dilates in response to introduction of a dilating fluid having a lower viscosity than a viscosity of a filling material inserted into the outer balloon, and the outer balloon dilates in response to the dilation of the inner balloon. |
