An expandable medical device has a plurality of elongated struts joined together to form a substantially cylindrical device which is expandable from a cylinder having a first diameter to a cylinder having a second diameter. At least one of the plurality of struts includes at least one opening extending at least partially through a thickness of said strut. A beneficial agent is loaded into the opening within the strut in layers to achieve desired temporal release kinetics of the agent. Alternatively, the beneficial agent is loaded in a shape which is configured to achieve the desired agent delivery profile. A wide variety of delivery profiles can be achieved including zero order, pulsatile, increasing, decrease, sinusoidal, and other delivery profiles.

Stent mounting assembly and a method of using the same to coat a stent

A support device for a stent and a method of coating a stent using the device are provided.

Support device for a stent and a method of using the same to coat a stent

Methods for coating different regions of an implantable device are disclosed. An embodiment of the method includes dipping a first portion of the implantable device into a first coating substance, and then centrifuging the implantable device to provide an even coating. Next, a second portion of the implantable device is dipped into a second coating substance, and the implantable device is again centrifuged, resulting in an even second coating. In another embodiment, a first coating substance is applied to an interior surface of a cylindrical implantable device, such as a stent or graft, and a second coating substance is applied to an exterior surface. A centrifuge step is performed so that the first coating substance is preferentially and uniformly applied on the interior surface of the implantable device and the second coating substance is preferentially and uniformly applied on the exterior surface of the implantable device.

Selective coating of medical devices

The present invention relates to method and apparatus for dispensing a beneficial agent into an expandable medical device. The method includes the step of placing an expandable medical device on a mandrel, the medical device forming a cylindrical device having a plurality of openings and dispensing a beneficial agent into the plurality of openings.
