Publication number: 20230310029Abstract: An apparatus for inserting a continuous analyte monitoring transmitter that includes an outer member, an inner member configured to telescope relative to the outer member, a transmitter, a bias member, an insertion device, and a pivot member. Force is applied to press the outer member toward an insertion site over the duration of a stroke. During a first portion of the stroke, the pivot member cannot pivot and the motion of the outer member translates to the insertion device until the biosensor is inserted at the insertion site. Over a second portion of the stroke, the continued motion causes a first pivot window in the outer member to overlap with a second pivot window in the inner member, allowing the pivot member to pivot and retract the insertion device from the insertion site, leaving the implanted biosensor.Type: ApplicationFiled: June 8, 2023Publication date: October 5, 2023Inventors: Jennifer L. Gass, Eugene Prais, Thomas A.J. Mayer, JR., Cameron M. Young, Nicholas Erekovcanski

Patent number: 11672451Abstract: A lancing device has a domed structure that can be depressed by application of a force by a user's finger so as to expose the tip of a needle. The domed structure is configured to move from a non-depressed state to a depressed state in a manner that allows for the piercing of the user's finger. The domed structure may then recoil to its original, non-depressed position upon the user ceasing to apply the force. Other embodiments of a lancing device are disclosed.Type: GrantFiled: April 10, 2020Date of Patent: June 13, 2023Assignee: Ascensia Diabetes Care Holdings AGInventors: Eugene Prais, Robert S.
