Holder for electrically charging a substrate during coating
First Claim
1. A stent holder for removeably holding a stent during a coating process wherein the stent holder comprisesa stent mounting portion comprising at least two arms upon which the stent is mounted, the at least two arms defining a hollow space therebetween, andan electrically chargeable section separate from the stent mounting portion,wherein the arms form an elliptical portion configured to exert force on an inner surface of the stent,wherein the arms are coupled to the electrically chargeable section that electrically charges the stent during the coating process and at least a portion of the electrically chargeable section includes a dimension larger than an inner diameter of the stent so that the stent sits on the electrically chargeable section, andwherein when the elliptical portion exerts force on the inner surface of the stent, the arms diverge from a central axis of the stent holder, making at least one bend, and converge at the central axis of the stent holder, or the arms diverge from a central axis of the stent holder and arc to converge at the central axis of the stent holder, the arms touching one another both where the arms diverge and where the arms converge.

Abstract
A stent holder for mounting and electrically charging a stent during coating of the stent using dry particles, the particles comprising inert polymers, pharmaceutical or biological agents, is provided. An assembly for supporting and electrically charging a stent during the coating of the stent using dry particles, the particles comprising inert polymers, pharmaceutical or biological agents, is provided. A chamber for creating an electrical field around a stent and for supporting, electrically charging, and exposing the stent to dry particles, the particles comprising inert polymers, pharmaceutical or biological agents, is provided. A method for creating an electrical field around a stent and for supporting, electrically charging, and exposing the stent to dry particles comprising inert polymers, pharmaceutical or biological agents is provided.
