Publication number: 20110160699Abstract: Embodiments of the invention provide swallowable devices, preparations and methods for delivering drugs and other therapeutic agents within the GI tract. Some embodiments provide a swallowable device such as a capsule for delivering drugs into the intestinal wall or other GI lumen. The device comprises a capsule sized to be swallowed and pass through the intestinal tract. The capsule can include at least one guide tube, one or more tissue penetrating members positioned in the guide tube, a delivery member, an actuating mechanism and a release element. The release element degrades upon exposure to various conditions in the intestine so as to release and actuate the actuating mechanism. Embodiments of the invention are particularly useful for the delivery of drugs which are poorly absorbed, tolerated and/or degraded within the GI tract.Type: ApplicationFiled: December 23, 2010Publication date: June 30, 2011Applicant: InCube Labs, LLCInventor: Mir Imran

Patent number: 7955305Abstract: An infusion media delivery device includes a housing having a base adapted to be secured to a user's skin. An infusion media reservoir is supported by the housing. A moveable hollow needle is selectively engageable with the reservoir to communicate infusion media from the reservoir. The needle is supported for movement relative to the housing base between a first position and a second position. The needle is spaced apart from a user's skin when in the first position and the base is secured to the user's skin, and the needle is arranged to pierce the user's skin when in the second position and the base is secured to the user's skin.Type: GrantFiled: August 23, 2005Date of Patent: June 7, 2011Assignee: Medtronic Minimed, Inc.Inventors: Sheldon B. Moberg, Ian B. Hanson, Paul S. Cheney, II

Patent number: 7938802Abstract: An injection device comprises a syringe (1) extendible against a spring bias (9) from a retracted position in a housing (2) to a projecting injecting position. A spring biased plunger has collapsible elbows (10) which, when the plunger is released, initially engage the end of the syringe to drive it to the projecting position, whereupon arresting of the syringe movement causes the elbows to collapse inside the syringe to allow the plunger to engage and drive the bung (3).Type: GrantFiled: June 23, 2005Date of Patent: May 10, 2011Assignee: Abbott Biotechnology Ltd.Inventors: Stephen Bicknell, Joseph F. Julian, William L. Rudzena

Publication number: 20110092905Abstract: An injector apparatus comprises a housing (101, 102) for a cartridge or syringe, a plunger (40) for cooperating in use with the cartridge or syringe to express successive doses, a dose setting arrangement (16, 20) to select a dose volume, and a drive mechanism (22, 24) releasable to advance said plunger in respective predetermined increments of magnitude to express said successive doses. The drive mechanism includes a drive spring (22) for imparting movement directly or indirectly to said plunger (40), and said dose setting arrangement comprises a dose setting element (16) moveable in a dose setting routine to define a magnitude of an increment of movement of said plunger for a given dose. The drive mechanism further includes a clutch arrangement (56) operable during said dose setting routine to inhibit forward movement of the plunger and/or to isolate said dose setting element from the force of said drive spring.Type: ApplicationFiled: October 23, 2009Publication date: April 21, 2011Applicant: OWEN MUMFORD LIMITEDInventor: Toby COWE
