Abstract: Disclosed are stent holding devices having a support mandrel and one or more stent retaining fixtures disposed on the mandrel. The retaining fixture may include a character identifier to facilitate tracking a stent mounted on the holding device. The retaining fixture may include a conical protrusion and a conical recess to allow any number of retaining fixtures to engage each other and be stacked on the mandrel. The retaining fixture may include a tubular member having a spiral cut that enables the diameter of the tubular member to be adjusted to allow for a frictional fit on the mandrel. The retaining fixture may have a Z-shaped or T-shaped structure configured to retain a stent. The stent retaining fixture may also have a filament for retaining a stent.

Abstract: A medical device includes a balloon expanded scaffold crimped to a balloon catheter. The scaffold has a network of rings formed by struts connected at crowns and links connecting adjacent rings. The scaffold has a polymer coating and is crimped to the balloon. The scaffold is rotated, or allowed to rotate during crimping to improve results from crimping, such as reduced damage to the coating.

Abstract: A system and method for coating an expandable member of a medical device comprises providing a dispenser in fluid communication with a fluid source with the dispenser having at least one outlet to dispense fluid of the fluid source therefrom. The outlet(s) of the dispenser is positioned proximate a surface of an expandable member, with relative movement between the outlet(s) and the surface of the expandable member established along a coating path, and fluid is dispensed from the dispenser to form a substantially continuous bead of fluid between the at least one outlet and the surface of the expandable member along the coating path, and simultaneously drying the fluid while dispensing the fluid from the dispenser to control flow of fluid on the surface of the expandable member. The fluid source can include a variety of therapeutic agents.
