PROTECTIVE SHEATH ASSEMBLY FOR A POLYMER SCAFFOLD |
| 摘要 |
A medical device includes a polymer scaffold crimped to a catheter having an expansion balloon. A sheath is placed over the crimped scaffold after crimping to reduce recoil of the crimped polymer scaffold and maintain scaffold-balloon engagement relied on to hold the scaffold to the balloon when the scaffold is being delivered to a target in a body. The sheath is removed by a health professional either by removing the sheath directly or using a tube containing the catheter. |

1. An apparatus, comprising:
a catheter including a scaffold comprising a polymer, the scaffold being crimped to a balloon; a sheath disposed over the scaffold; a tube containing at least a portion of the catheter; and a member disposed within the tube, wherein the member partially or fully removes the sheath from the scaffold when the tube is separated from the catheter; and wherein the catheter is configured for being introduced into a mammalian body only after the sheath is removed from the scaffold. |
