SPIN-TO-OPEN ATHERECTOMY DEVICE WITH ELECTRIC MOTOR CONTROL |
摘要 |
A rotational atherectomy system is disclosed, comprising: an elongated, flexible spin-to-open drive shaft having a distal end for insertion into a vasculature of a patient and having a proximal end opposite the distal end remaining outside the vasculature of the patient; a concentric or eccentric abrasive element, preferably a solid crown, attached to the drive shaft proximate the distal end of the drive shaft; an electric motor rotatably coupled to the proximal end of the drive shaft, the electric motor being capable of rotating the drive shaft in a spin-to-open direction; and control electronics for monitoring and controlling the rotation of the electric motor. When an obstruction at the distal end is detected by the applied torque and/or current reaching a predetermined maximum allowed level and with the drive shaft opened to a maximum allowed outer diameter, power to the motor is eliminated. |
