Abstract
Embodiments of the invention include apparatus and methods for coating drug eluting medical devices. In an embodiment, the invention includes a coating apparatus including a coating application unit comprising a movement restriction structure; a fluid applicator; and an air nozzle. The apparatus can further include a rotation mechanism and an axial motion mechanism, the axial motion mechanism configured to cause movement of at least one of the coating application unit and the rotation mechanism with respect to one another. Other embodiments are also included herein.
Claims16
A coating apparatus comprising:
- a coating application unit comprising
- a movement restriction structure;
- a fluid applicator;
- an air nozzle;
- and
- a rotation mechanism;
- and
- an axial motion mechanism, the axial motion mechanism configured to cause movement of at least one of the coating application unit and the rotation mechanism with respect to one another,
- the movement restriction structure comprising a first body member and a second body member, the first body member defining a first portion of a channel and the second body member defining a second portion of a channel, the first body member and second body member configured to rotate between a closed position where a balloon is locked in place in the channel and an open position where the balloon is released.
A coating apparatus comprising:
- a coating application unit comprising
- a movement restriction structure;
- a fluid applicator;
- an air nozzle;
- and
- a rotation mechanism;
- and
- an axial motion mechanism, the axial motion mechanism configured to cause movement of at least one of the coating application unit and the rotation mechanism with respect to one another;
- the movement restriction structure comprising a first body member comprising a curved segment and an end, the curved segment defining a portion of a channel, the first body member further comprising an alignment lip adjacent the end, the alignment lip comprising a surface that is angled away from the channel defined by the curved segment.
