Patent number: 7407500Abstract: An osmotic delivery system flow modulator assembly, an osmotic delivery system with a flow modulator assembly, and a method of assembling an osmotic delivery system. The osmotic delivery system flow modular assembly includes a body having a hole located through the body and communicating two opposing ends of the body. The use of the osmotic delivery system flow modulator assembly lessens the chance that air or gas pockets will form in the enclosure of the osmotic delivery system during assembly of the system. Because less air is within the osmotic delivery system, performance of the system is enhanced. Use of the flow modulator assembly also lessens the chance that beneficial agent will be wasted during assembly of the osmotic delivery system.Type: GrantFiled: November 22, 2004Date of Patent: August 5, 2008Assignee: ALZA CorporationInventors: Lewis L. Peterson, Fred H. Maruyama, Houdin Dehnad, Lawton Hom, Kevin S. Ly, Craig R. Davis, John R. Peery

Patent number: 7381201Abstract: The present invention provides a reusable spring driven autoinjector. The drive mechanism of the autoinjector of the present invention includes one or more drive springs formed of a shape memory alloy. Therefore, by alternating the shape memory alloy forming the one or more drive springs between austenite phase before an injection and a martensite phase after injection, the reusable autoinjector of the present invention is capable of providing an injection force that is higher than the compressive force required to cock the drive mechanism in preparation for a subsequent injection operation.Type: GrantFiled: June 24, 2003Date of Patent: June 3, 2008Assignee: Alza CorporationInventors: Scott Gilbert, Pedro de la Sema

Patent number: 7338663Abstract: The present invention includes an expandable osmotic layer and a coating suspension for providing an expandable osmotic layer, both of which are useful for the manufacture of controlled release dosage forms. The expandable osmotic layer of the present invention may be produced using the coating suspension of the present invention. Advantageously, the coating suspension of the present invention can be used to coat expandable osmotic layers under both wet and dry process conditions without sacrificing the quality of the expandable osmotic layers produced, and therefore provides a relatively robust coating suspension that facilitates commercial production of controlled release dosage forms including a coated expandable osmotic layer.Type: GrantFiled: June 28, 2003Date of Patent: March 4, 2008Assignee: ALZA CorporationInventors: Shaoling Li, Liang-Chang Dong, Padmaja Shivanand, Patrick S. L. Wong

Patent number: 7156257Abstract: The present invention provides a compressed gas cylinder that is capable of storing a compressed fluid at high pressures. The cylinder of the present invention includes a body terminating in an inwardly domed cap. The dome included in the cap of the compressed gas cylinder of the present invention is formed such that the material near the tip of the dome is relatively thinner than the material near the base of the dome. The tip of the dome, therefore, creates a pierce region in the cap that can be pierced through the application of a relatively low pressure.Type: GrantFiled: March 28, 2003Date of Patent: January 2, 2007Assignee: Alza CorporationInventor: Pedro E. de la Serna

Patent number: 7097634Abstract: The present invention includes an automatic injection device that reliably provides automatic needle retraction even when manufactured with part and assembly tolerances typical of low-cost and high-volume manufacturing processes. The injector of the present invention includes a body, a syringe cartridge, a drive mechanism, and a bias mechanism. The drive mechanism includes an energy source, a drive member, and a compound plunger with a releasable coupling. Significantly, the compound plunger included in the drive mechanism is designed to ensure needle retraction occurs after the automatic injection device has delivered the desired dose of medicament. Moreover, the design of the compound plunger included in the injector of the present invention can compensate for part and assembly tolerances typical of low-cost, high volume manufacturing processes, enabling the fabrication of a low cost automatic injection device providing reliable automatic needle retraction.Type: GrantFiled: July 31, 2003Date of Patent: August 29, 2006Assignee: Alza CorporationInventor: Scott Gilbert

Patent number: 7011649Abstract: The present invention provides a syringe cartridge that is sufficiently robust to be used in autoinjectors that generate injection forces sufficient to deliver viscous medicaments. The syringe cartridge of the present invention includes a syringe, a bias mechanism, and a casing. The casing of the syringe cartridge of the present invention includes a collapsible portion and a fixed portion. Advantageously, the collapsible portion of the casing collapses within the fixed portion of the casing as the syringe is driven through its stroke within the syringe cartridge. As the collapsible portion collapses within the fixed portion, the length of the syringe cartridge is effectively reduced, which, in turn, allows the use of a shorter plunger and thereby facilitates the construction of a more compact autoinjector.Type: GrantFiled: November 8, 2002Date of Patent: March 14, 2006Assignee: ALZA CorporationInventors: Pedro E. De La Serna, Scott J. Gilbert

Patent number: 7011850Abstract: A dosage form for delivery of a therapeutic agent to a subject is described. The dosage form contains: (a) an outer wall defining an interior compartment; (b) within the interior compartment, a therapeutic agent; (c) at least one exit orifice formed by laser ablation of the outer wall for release of the agent therethrough, and (d) a barrier layer disposed between the outer wall and the interior compartment in at least a region corresponding to the exit orifice. The barrier layer comprises a material that allows the barrier layer to remain intact during laser-formation of the at least one exit orifice in the outer wall. Also disclosed is a method for controlling the depth of laser ablation of a dosage form during laser formation of an exit orifice in an outer wall of the dosage form.Type: GrantFiled: December 13, 2000Date of Patent: March 14, 2006Assignee: Alza CorporationInventor: Johan H. Geerke
