Implant insertion tool with a tissue stop configuired to engage tissue

摘要

An insertion tool 500 for insertion of an implant into a punctum of a patient, comprises a tool body having a distal portion configured to hold the implant on an outer implant surface, the distal portion having an inner lumen 560 with an internal depth stop 540, where a distal end of the tool body includes a tissue stop 530 configured to engage tissue proximate the punctum, and a plunger 550 slidable within the inner lumen 560 to engage and dispense the implant. The plunger 550 has a stop 545 configured to engage with the internal depth stop 540, where the engagement of the stop 545 and the internal depth stop 540 limits the insertion depth of the implant into the punctum.
