| 摘要 |
A stent (24) made of a biodegradable copolymer is applied to the exterior surface of an angioplasty balloon (22). Upon being positioned at a restricted vessel section (20) a contrast fluid present in the balloon (22) is heated which results in the stent (24) being heated. Heating the stent (24) and expanding the angioplasty balloon (22) allows the stent (24) to expand so that it presses against the vessel wall. The balloon (22) is then collapsed leaving the stent (24) in position. |
