US 12,751,859 B2 · Intracanalicular depot inserter device

Abstract

Disclosed in certain embodiments is an intracanalicular injectable applicator device includes a body forming a cavity and a cannula coupled to a first distal end of the body. The cannula forms a channel that is aligned with the cavity of the body. The cannula is configured to store an intracanalicular injectable in the channel. The intracanalicular injectable applicator device further includes a tip structure coupled to the body. The tip structure is disposed around at least a portion of the cannula. A distal end of the tip structure is configured to dilate a lacrimal punctum by inserting the distal end of the tip structure into the canaliculus via the lacrimal punctum. The intracanalicular injectable applicator device further includes an actuating structure configured to push the intracanalicular injectable through the channel and the distal end of the tip structure into a canaliculus via a lacrimal punctum.

Dependent claims

A tip structure of an intracanalicular injectable applicator device, wherein the tip structure comprises:

a first distal end that attaches to a body of the intracanalicular injectable applicator device;
an inner surface forming a recess that receives a first cannula distal end of a cannula of the intracanalicular injectable applicator device, wherein a second cannula distal end of the cannula is coupled to the body;
and
a second distal end comprising a beveled tip configured to be inserted in a lacrimal punctum to dilate the lacrimal punctum and to inject an intracanalicular injectable from the cannula into a canaliculus via the lacrimal punctum.
