Abstract
A catheter rotation drive apparatus includes first and second drives that are engageable to an output shaft. When the first drive is engaged to the output shaft and rotated, the output shaft rotates in an output rotation direction, and when the second drive is engaged to the output shaft and rotated, the output shaft rotates in the output rotation direction.
Claims14
A catheter rotation drive apparatus, comprising:
- a first pair of input drives coupled to one another via a first belt, the first pair of input drives comprising a first drive and a first engagement shaft, the first drive coupled to a first drive pulley;
- a second pair of input drives coupled to one another via a second belt, the second pair of input drives comprising a second drive and a second engagement shaft, the second drive coupled to a second drive pulley;
- wherein each of the first and second drives are engageable to an output shaft;
- wherein when the first drive is engaged to the output shaft and rotated, the output shaft rotates in an output rotation direction,
- wherein when the second drive is engaged to the output shaft and rotated, the output shaft rotates in the output rotation direction,
- wherein when the first engagement shaft of the first pair of input drives is engaged, the second engagement shaft of the second pair of input drives is disengaged, such that when the first drive pulley is rotated in its drive direction, the output shaft is caused to rotate via the first belt in the output rotational direction.

A method of fabricating a rotatable catheter comprising:
- providing first and second drive shafts that are engageable to an output shaft;
- wherein:
- when the first drive shaft is engaged to a first engagement shaft and to the output shaft, a second drive shaft is disengaged from a second engagement shaft and from the output shaft, and when the first drive shaft is rotated, the output shaft rotates in an output rotation direction;
- and
- when the second drive shaft is engaged to the second engagement shaft and to the output shaft, the first drive shaft is disengaged from the first engagement shaft and from the output shaft, and when the second drive shaft rotated, the output shaft rotates in the output rotation direction.
