Patent number: 11738150Abstract: A drug delivery device (100) for administering a low dose of a medicament includes a housing (111) and a drug reservoir (101) disposed in the housing (111). A needle (135) is connected to the drug reservoir (101). A pressure applying member (113) is movably connected to the housing (111) and is movable between first and second positions. The pressure applying member (113) does not apply pressure to the drug reservoir (101) in the first position and applies pressure to the drug reservoir (101) in the second position to dispense medicament stored in the drug reservoir (101). A method of administering a low dose of insulin to simulate a first-phase insulin response of a pancreas is also disclosed.Type: GrantFiled: December 16, 2020Date of Patent: August 29, 2023Assignee: Becton, Dickinson and CompanyInventors: Margaret Taylor, James Bates, Roman Tunkel, Jay Butterbrodt, Gary Searle, Joshua Horvath, Keith Knapp, II, Edward Gillen

Patent number: 11471592Abstract: Provided is an extended use self-contained, wearable medical device. The device is preferably configured with an infusion deployment mechanism for variably inserting and retracting an infusion needle to different depths, or completely retracting the infusion needle from the infusion site and then re-inserting the infusion needle after a predetermined period of time, throughout an infusion cycle for extending the viability of the infusion site. Another embodiment comprises dual needle deployment mechanisms which may also variably insert and retract the infusion needles. A flow sensor is preferably provided for detecting the stoppage of flow through the infusion cannula and signaling the needle deployment mechanism to attempt infusion at a different depth or to deploy a second infusion needle. A re-fillable reservoir assembly is preferably provided for supplying a drug over the extended use of the device.Type: GrantFiled: June 3, 2016Date of Patent: October 18, 2022Assignee: BECTON, DICKINSON AND COMPANYInventors: Gary Searle, Keith N Knapp, II, Roman Tunkel, Peter Skutnik, Lionel Vedrine

Patent number: 9867929Abstract: An infusion pump system is disclosed for dispensing liquid medication, such as insulin. The infusion pump system includes a first reservoir for storing liquid medication, a first fluid driver for exerting pressure on the first reservoir, a second reservoir for storing liquid medication, and a second fluid driver for exerting pressure on the second reservoir. One or more valves are used to permit flow of liquid medication from the first reservoir to the second reservoir, and to permit flow of liquid medication from the second reservoir to an infusion site. Each of the valves is selectively opened or closed to fill the second reservoir with liquid medication from the first reservoir and to dispense liquid medication from the second reservoir to the infusion site. A controller and one or more sensors are used to monitor and control the system.Type: GrantFiled: August 9, 2013Date of Patent: January 16, 2018Assignee: Becton, Dickinson and CompanyInventors: Gary Searle, Roman Tunkel, William Tormey, III, Andrew Leonczyk, David Pollock, Paul Naumann, Kenneth Focht
