摘要:
The present invention provides pharmaceutical compositions. In one aspect, a pharmaceutical composition is provided having a plurality of polymeric film layers heat sealed together as a multilayer structure and having an active agent dispersed within the multilayer structure. The multilayer structure is configured to release the active agent upon administration to a subject, either in a controlled release or immediate release manner.

Implantable medical devices such as stents, methods of making medical devices, and systems for making medical devices are disclosed herein. In one exemplary embodiment, medical device includes a stent that is coated at least on a portion of one surface by an ink-jet device.
摘要:
A cement composition comprises free-flowing spray-dried unreacted cement particles and a liquid binder. The spray-dried particles may include a poly acid. A method for making a cement composition using spray dried cement particles comprises a) providing cement particles, b) milling or sieving said cement particles so as to produce cement particles having a desired average size, c) adding a liquid carrier to said particles before or after milling so as to form a slurry, d) adding a poly acid to said particles while maintaining the pH of the slurry above about 6, and e) spray-drying the slurry. The resulting particles can be used in conjunction with a liquid binder to form a monolith having a desired shape.

A solution is provided that includes a non-aqueous organic solvent within which a solute has been dissolved. A thermal-fluid ejection mechanism is provided that has fluid-ejection nozzles and that is capable of thermally ejecting the solution. A device medium is provided that has a three-dimensional surface on which the solution is to be ejected. The fluid-ejection nozzles of the thermal fluid-ejection mechanism are controlled to eject the solution onto the three-dimensional surface of the device medium in accordance with a desired pattern.
