Abstract
The present invention is directed to methods and systems for aligning and coating a medical device during a single coating cycle. A first section of an applicator may apply a contact force to surfaces of the medical device. The contact force may align and remove surface irregularities from the medical device prior to coating the medical device with coating. The coating may be resident on a second section of the applicator.
Claims21
A method for coating a stent, the method comprising the steps of:
- providing a stent having a lattice portion comprised of a plurality of struts;
- positioning the stent on a mandrel;
- providing an applicator including first and second sections forming an offset;
- aligning the struts via a contact force applied by the first section;
- and
- delivering coating to the struts from the second section.
3 more elements
A system for coating a medical device, comprising:
- an applicator having first and second sections which form an offset, the first and second sections are located along an edge of the applicator;
- and
- a fluid source communicating with the second section;
- wherein at least one of the first and second sections of the applicator and the medical device move with respect to one another so that the first section applies a contact force to the medical device while the second section applies a coating.
1 more element
A system for coating a medical device, comprising:
- an applicator having first and second sections located along an edge, the first section forms a contact surface and the second section is comprised of a plurality of recesses;
- and
- a fluid source communicating with the second section;
- wherein at least one of the first and second sections of the applicator and the medical device move with respect to one another so that the first section applies a contact force to the medical device while the second section applies a coating.
