  • Patent number: 6508808
    Abstract: An osmotic delivery system for controlled delivery of a beneficial agent includes an implant capsule having a beneficial agent reservoir, an osmotic agent which expands on contact with fluid imbibed through a permeable membrane retained by the implant capsule, a delivery port, and a valve for opening and closing the delivery port. When the osmotic agent expands, a pressure is exerted against a separating member positioned between the beneficial agent reservoir and the osmotic agent. The separating member moves within the capsule, thereby forcing the valve to move a distance such that the beneficial agent can exit the reservoir through the delivery port.

  • Patent number: 6452133
    Abstract: Methods and apparatus for laser treating batches of pharmaceutical dispensers are provided. Sequential batches of untreated dispensers are carried on alternate batch carriers that are advanced into associated alternate stationary laser treatment stations. The multiple stationary laser treatment stations are located within a region of adjacency in which a single laser source can be operated to treat alternate batches of dispensers positioned within the associated alternate laser treatment stations. A laser controller directs the laser beam to alternatingly operate in each laser treatment station and, within each laser treatment station, to treat each dispenser in a batch of dispensers positioned therein. An advance coordinator advances the batch carriers in coordination with the activity of the laser controller in a repeating alternating cycle.
