摘要:
Exemplary embodiments of the present disclosure are directed to a device for facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein. The device includes an intravascular device including a shaft having a distal end and a proximal end. The device further includes a handle assembly fixed about the proximal end of the shaft, the handle assembly including a first portion. Further rotation of the first portion in a first direction about a longitudinal axis of the shaft causes rotation of the shaft in the first direction when a torque applied by the first portion to the shaft is below a first maximum torque. Still further, rotation of the first portion in the first direction about a longitudinal axis of the shaft does not cause rotation of the shaft in the first direction when the torque applied by the first portion to the shaft is equal to or above the first maximum torque.
