摘要： A stent graft delivery system including a stent graft cover, a screw gear, and a handle assembly. The handle assembly includes an external slider, a T-tube, and a Y-adapter. The external slider is configured to rotate about the screw gear. The T-tube and the Y-adapter collectively form a hub configured to slide linearly along the screw gear as the external slider rotates. The T-tube defines a main lumen port extending therethrough and is configured to receive the stent graft cover and a main lumen. The Y-adapter defines a secondary lumen port and is configured to receive a secondary lumen.

摘要： A stent graft delivery system and method of operating the same are disclosed. The system includes a stent graft cover, a screw gear, and a handle assembly. The handle assembly includes an external slider configured to rotate about the screw gear, and a central hub configured to slide linearly along the screw gear as the external slider is rotated. The central hub defines a main lumen port extending therethrough and configured to receive the stent graft cover, and a branched lumen port configured to receive a branched lumen. The stent graft cover can be fixed to and within the main lumen port. Rotation of the handle causes the central hub to slide linearly, which simultaneously retracts the stent graft cover and the branched lumen.
