Publication number: 20240091435Abstract: Disclosed herein are various embodiments of clutching mechanisms applicable to a dual reservoir pumping mechanism for a drug delivery device, the clutching mechanisms serving to allow translation of one of the reservoirs during the filling process and thereafter connecting the reservoirs together such that one can be driven relative to the other one by means of a leadscrew or other driving mechanism.Type: ApplicationFiled: September 13, 2023Publication date: March 21, 2024Inventors: Maureen MCCAFFREY, Soroush KAMRAVA, Steven CARDINALI, Jeffrey BARNES, Kyle BREINGAN, Lucas MCGAHREN, Daniel BARRETT

Publication number: 20240042126Abstract: Disclosed herein is a double reservoir configuration for a pumping mechanism for a drug delivery device wherein one reservoir is rigidly fixed to a housing of the device and the other reservoir moves linearly translates with respect to the fixed reservoir. To avoid having either the input fluid port or the output fluid port moves as the second reservoir linearly translates, one port is in fluid communication with the fixed reservoir and a second fluid port is in communication with the moving reservoir via a hollow tube supporting a static plunger disposed within the moving reservoir. This arrangement provides for the added benefit of allowing air trapped within either of the reservoirs to be almost completely removed as the pump mechanism is filled with the fluid.Type: ApplicationFiled: January 27, 2023Publication date: February 8, 2024Inventors: Soroush KAMRAVA, Kyle BREINGAN, Maureen MCCAFFREY, Jeffrey BARNES

Patent number: 11819675Abstract: A needle mechanism module for automatically inserting a fluid path into a patient for drug delivery is provided. The needle mechanism module can be a component of a wearable drug delivery device. The needle mechanism module can insert a needle and cannula into the patient responsive to activation of the drug delivery device by a user. After insertion, the needle can be automatically retracted, leaving only the cannula in the patient. As a result, discomfort of the user is reduced.Type: GrantFiled: December 17, 2020Date of Patent: November 21, 2023Assignee: INSULET CORPORATIONInventors: Maureen McCaffrey, Ian McLaughlin

Publication number: 20230211077Abstract: Disclosed herein are various embodiments providing an expandable, flexible reservoir for use in a wearable drug delivery device. The reservoir comprises a flexible enclosure made with plastic film which incorporates pleats forming the side walls thereof to increase the volume efficiency and to avoid a “pillowing” effect when the reservoir is filled. The pleats may be formed at non-right angles with respect to each other such as to form a curved side walls for the reservoir. In variations of the invention, various methods are disclosed for maintaining a vacuum with the reservoir during its shelf life.Type: ApplicationFiled: January 4, 2023Publication date: July 6, 2023Inventors: Maureen MCCAFFREY, Daniel ALLIS

Patent number: 11672917Abstract: Drive systems for a drug delivery device are provided. The drive systems can be positioned within a container that stores a liquid drug to be delivered to a user. The drive systems can be coupled to a plunger positioned within the container. The drive systems can be incrementally advanced to drive the plunger further into the container, thereby expelling a portion of the stored liquid drug from the container for delivery to the user. The container can be any type of container including a pre-filled, standardized drug cartridge. The drive systems and container can be components of a wearable drug delivery device.Type: GrantFiled: September 30, 2020Date of Patent: June 13, 2023Assignee: INSULET CORPORATIONInventors: Steven Cardinali, David Nazzaro, Daniel Allis, Maureen McCaffrey

Patent number: 11633541Abstract: Drug delivery systems with reduced hold-up volumes are provided. The drug delivery systems include a cartridge configured to hold a liquid drug. A cartridge stopper is positioned in a first portion of the cartridge. A needle guide component is positioned within the cartridge stopper. A needle is positioned within a central opening of the needle guide. A plunger is positioned in a second portion of the cartridge. The plunger includes a fluid path pocket facing and aligned with the central opening of the needle guide component. The plunger is driven toward the cartridge stopper to expel the liquid drug from the cartridge through the needle. An end of the needle can be positioned within the fluid path pocket when the plunger is pushed against the cartridge stopper, ensuring that only a small volume of the liquid drug remains in the cartridge when delivery of the liquid drug is completed.Type: GrantFiled: February 19, 2020Date of Patent: April 25, 2023Assignee: INSULET CORPORATIONInventors: Maureen McCaffrey, David Nazzaro, Ian McLaughlin, Simon Kozin

Publication number: 20220288302Abstract: Disclosed herein are devices and methods for causing the linear translation of a plunger through a reservoir containing a fluid. A flexible member, for example, a wire or a ribbon, is coupled to the plunger and extends through a wall of the reservoir toward which the plunger is being linearly translated. A pulling force on the flexible member caused by a drive mechanism causes the plunger to linearly translate toward the end wall of the reservoir, thereby forcing any fluid contained in the reservoir out of the reservoir through a fluid port.Type: ApplicationFiled: February 17, 2022Publication date: September 15, 2022Inventors: Daniel BARRETT, Soroush KAMRAVA, Maureen MCCAFFREY

Publication number: 20220105260Abstract: Examples of fluid delivery drive system and/or pump system that creates a vacuum in a fluid line for drawing and expelling fluid are provided. The vacuum may be created by separating two components that are positioned within the sealed fluid line. Once the two components are separated and the fluid is contained within the volume created between the separated components, the two components may be shuttled within the sealed volume. The movement of the two components can seal off an inlet to the fluid line and then open a pathway to an outlet from the fluid line while ensuring the created volume between the two components is maintained constant. The two components can then be moved back together to expel the fluid from the created volume through the outlet for delivery, for example, to a patient. Other examples are disclosed and described.Type: ApplicationFiled: December 16, 2021Publication date: April 7, 2022Applicant: Insulet CorporationInventors: Steven CARDINALI, Daniel ALLIS, Ian HANSON, Maureen MCCAFFREY, Chris GOETCHIUS

Patent number: 11045603Abstract: Systems for piercing a septum of a drug delivery device is disclosed. The drug delivery device may include a needle conduit having an end and a drug container having a septum. The septum piercing mechanism may include a needle support operatively coupled to the needle conduit. The septum piercing mechanism may be movable from a first, unactivated configuration to a second, activated configuration. In the unactivated configuration, the septum seals an interior of the drug container from the end of the needle conduit. In the activated configuration, the end of the needle conduit pierces through the septum placing the needle conduit in fluid communication with the drug container. In one embodiment, activation may cause the needle support to move towards the drug container. In one embodiment, the needle support may be moved by a biasing member. Alternatively, in another embodiment, the needle support may be moved by a cam mechanism.Type: GrantFiled: February 21, 2018Date of Patent: June 29, 2021Assignee: INSULET CORPORATIONInventors: Maureen McCaffrey, Ian McLaughlin
