OCCLUSION-CROSSING DEVICES |
| 摘要 |
A catheter device for crossing occlusions includes an elongate catheter shaft, a rotatable tip configured to rotate relative to the elongate catheter shaft, a drive shaft, and an OCT imaging sensor. The rotatable tip includes a housing coupled with the elongate catheter shaft and cutting wedges extendable from the housing. The drive shaft has a central lumen extending therethrough and extends within the elongate catheter shaft. The drive shaft is coupled with the wedges and is configured to rotate the rotatable tip. The OCT sensor includes an optical fiber coupled with the rotatable tip and configured to rotate therewith. The elongate catheter shaft is configured to move axially over the drive shaft to extend and retract the wedges from the housing while maintaining a fixed position of the imaging sensor relative to the cutting wedges. |
