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

Publication number: 20230064224Abstract: Pump subsystem for fluid delivery (e.g., in a wearable patch pump) comprises a fluid chamber with pumping motion and a valve shaft assembly with valving motion, both being driven by the same drive mechanism. Fluid chamber has variable volume chamber provided by a piston driven by the drive mechanism and translated relative to a plug in the pump housing. Piston extends the fluid chamber during an intake stroke and retracts the fluid chamber during a discharge stroke. Valve assembly has at least one valve shaft controllably translated by the drive mechanism to selectively align a first throughway with an opening in the pump chamber and a fluid intake port for an intake stroke to draw fluid into the fluid chamber, and align a second throughway with the opening in the pump hamber and a fluid discharge port for an discharge stroke to discharge fluid from the fluid chamber.Type: ApplicationFiled: January 20, 2021Publication date: March 2, 2023Applicant: Becton, Dickinson and CompanyInventors: Alessandro PIZZOCHERO, Mark WOOD, Shehryar SIDDIQUI, Elizabeth GURIN, Keith KNAPP

Patent number: 11315674Abstract: Improved systems and methods for medicine delivery, and in particular, improved insulin pen needles and related devices are provided. Smart injection devices record and transfer data including medicine level, delivered dose, dose confirmation, and dose time and date. Additional data captured may include glucose concentration, insulin level, carbohydrates ingested, stress level, exercise, blood pressure, and glucose high and low excursion events. Various means of data collection and analysis are provided and systems can identify and flag patients who require intervention. Smart sleeves and add sensing capability to standard insulin pens. Pen needles are provided with sensing capability to confirm and measure doses delivered by insulin pen. A two-part pen cap include a primary sleeve that connects to the insulin pen and an end cap that provides for capturing the time of dose delivery, and monitoring the hold time for a dose delivery after plunger movement.Type: GrantFiled: October 20, 2015Date of Patent: April 26, 2022Assignee: BECTON, DICKINSON AND COMPANYInventors: Keith Knapp, Neil McCaffrey, Jay Butterbrodt, Margaret Taylor, Ruth Markowitz, Gary Searle, Michael Gibney, James Salemme, James Walker, Sean Sullivan, Ernest Elgin, Rita Saltiel-Berzin

Patent number: 10918807Abstract: A medicament delivery system is disclosed including disposable pen needles (10, 60, 120) each having a stainless steel needle or cannula (12, 62, 122) with a concealed or a very short non-injection end (28, 78, 128) that is not intended to pierce the septum (8) of the drug storage compartment (6) of a medication pen (2), thus reducing the risk of needle stick injuries. Several types of non-metallic interfaces (30, 80, 100) serve as intermediaries between the pen needles (10, 60, 120) and a medication pen (2) and perform the septum-piercing function. These improve the flow of medicament to the needle or cannula (12, 62, 122) due to the larger lumen of the plastic interface (30, 80, 100) that directly feeds medicament to the needle or cannula (12, 62, 122), allowing for even smaller gauge needles for improved patient comfort.Type: GrantFiled: May 31, 2016Date of Patent: February 16, 2021Assignee: Becton, Dickinson and CompanyInventors: Keith Knapp, Sudarsan Srinivasan

Patent number: 10022504Abstract: A pen needle (101) for use with a drug delivery device (100) includes a hub body (113) having internal threads (216) to receive the drug delivery device (100). A post (121) is connected to the hub body (113). A needle (103) is rigidly fixed to the post (121). The post (121) is separable from the hub body (113) such that the needle (103) is removed with the post (121). The fluid path is not disturbed by such removal because the entire needle (103) is removed with the post (121). Removal of only the post (121) and needle (103) reduces the volume of waste required for disposal, thereby increasing the effective capacity of a sharps container.Type: GrantFiled: September 15, 2010Date of Patent: July 17, 2018Assignee: Becton, Dickinson and CompanyInventors: Joshua Horvath, Joseph Brizzolara, Charles Hwang, James Bates, Keith Knapp
