Publication number: 20220168510Abstract: A controlled multidosing delivery device for use with a syringe includes a housing, a plunger rod and a drive shell. The housing having an axially extending chamber including openings at either end, the distal end being adapted for attachment to the syringe barrel. The plunger rod includes a contact button at the proximal end of an elongated shaft and a pusher feature at the distal end. The drive shell is disposed for axial translation within the axially extending chamber. The drive shell includes a head disposed for translation along the axis to provide dose delivery, a plurality of engagement surfaces for engagement by the pushing feature, and a retention feature that inhibits proximal movement of the drive shell when engaged.Type: ApplicationFiled: April 9, 2020Publication date: June 2, 2022Applicant: Congruence Medical Solutions, LLCInventors: Lou Castagna, Lance Wetzel, Gautam Nithyanand Shetty
