Rotational medical device with increased drag coefficient for fluid circulation
The patent application (Publication Number: US20240032960A1) describes a rotational medical device with a prime mover connected to a drive shaft that can achieve a working diameter greater than its resting diameter during high-speed rotation. The device includes an abrasive element attached to the drive shaft, with its center of mass radially offset from the axis of rotation. Additionally, surface imperfections are created on at least a portion of the external surface of the drive shaft, both proximal and distal to the abrasive element, to increase the drag coefficient of the drive shaft.
This innovative design allows the rotational medical device to operate effectively during high-speed rotation by increasing the drag coefficient of the drive shaft through strategically placed surface imperfections. By having the abrasive element attached to the drive shaft with a radially offset center of mass, the device can achieve a working diameter larger than its resting diameter. These features work together to enhance the performance and efficiency of the device, potentially leading to improved outcomes in medical procedures where rotational tools are utilized.
