Declarations under Rule 4.17: as to applicant's entitlement to apply for and be granted a patent (Rule 4.17(ii)) as to the applicant's entitlement to claim the priority of the earlier application (Rule 4.17(iii)) Published: with international search report (Art. 21(3)) with amended claims and statement (Art. 19(1)) 1-1 O 01 00 O C (54) Title: CONTROLLED DELIVERY SYRINGE DEVICE (57) : A controlled delivery syringe device includes a syringe barrel having a proximal end and distal end which defines a chamber for containing an injectable material. A plunger rod is associated with the syringe barrel and a plunger is secured thereto which is axially movable within the syringe barrel. A plurality of equally and sequentially spaced periodic features are associated with the plunger rod and a counter member is engageable with the periodic features. Application of a distally directed force to the plunger rod results in disengagement and reengagement of the counter member with the sequentially spaced periodic features on the plunger rod, enabling advancement of the plunger rod and plunger in the syringe barrel while providing tactile feedback of dose progression of the injectable material. A method of retrofitting a syringe with a device for injecting a metered dose of injectable material is also provided.
