Abstract
Official abstract text for this publication.
The present disclosure teaches methods of controlling the release rate of agents from a polymeric matrix. The methods relate to the application of pressure, and optionally, in combination with heat, to a polymeric coating.
First claim
Opening claim text (preview).
We claim: 1. A method comprising: obtaining a medical device with a polymeric coating layer, the polymeric coating layer having been dried; applying a pressure greater than ambient to the dried polymeric layer of the medical device using a pressure vessel; and optionally applying heat to the dried polymeric layer of the medical device in combination with the application of the pressure. 2. The method of claim 1 , wherein the pressure is pulsed.…
