Abstract
Methods of coating a stent are disclosed. In one example, the method includes positioning the stent on a support element configured to support the stent while rotating the stent. The support element has at least three elongate elements converging inwardly from a proximal end to a distal end of each element to form a conical or frusto-conical shape. The support element can be configured to be positioned within an end of the stent. The stent can be pinched between the support element and a second support element. A coating composition is applied to the stent. The method can further include pulsing the support element and/or the second support element to change a contact position of the stent with respect to the support element or the second support element; rotating the support element and the second support element at two different rates; or translating the support element from a first point of contact with the stent to a second point of contact with the stent.
