Systems and methods for rotating and coating an implantable device
First Claim
1. A method for applying a coating to an implantable device, comprising:
- positioning an implantable device relative to a material delivery apparatus, the implantable device having a first longitudinal axis;
producing a spray pattern of an application material using the material delivery apparatus; and
rotating the implantable device at a speed sufficient to reduce the size of a portion of droplets of the spray pattern and relative to a rotation member upon which the implantable device is disposed, the rotation member having a second longitudinal axis, and when the first longitudinal axis and the second longitudinal axis are generally parallel the first longitudinal axis and the second longitudinal axis are offset at an offset distance.

Abstract
A method for applying a coating to an implantable device is disclosed. The method includes positioning an implantable device relative to an ultrasonic material delivery apparatus. The implantable device is rotated at a relative speed. The relative speed may be more than 120 revolutions per minute. An application material is applied to the implantable device using the ultrasonic material delivery apparatus. The relative speed may be sufficient to reduce the size of at least a portion of droplets of the application material. A system for rotating an implantable device is disclosed. The system includes an implantable device and a rotation system configured to rotate the implantable device. A longitudinal axis of the implantable device and a longitudinal axis of a rotation member of the rotation system may be offset a desired dimension. An inside diameter of the implantable device may be larger than an outside diameter of a rotation member.

7. A method for rotating a stent, the method comprising:
-
positioning a generally annular stent having an inner surface relative to a rotation member having an outer surface such that less than the entire inner surface of the stent and less than the entire outer surface of the rotation member that is possible of being in general contact with each other are in general contact with each other, the stent having a first longitudinal axis and the rotation member having a second longitudinal axis, and when the first longitudinal axis and the second longitudinal axis are generally parallel the first longitudinal axis and the second longitudinal axis are offset at an offset distance; and applying a rotational force to the rotation member, such that the rotation member begins to rotate at a specified rotation speed causing at least a portion of the outer surface of the rotation member to apply a frictional force to at least a portion of the inner surface of the stent and rotate the stent relative to the rotation member. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)
