29. An implant insertion tool for insertion of a lacrimal implant into a punctum of a patient, the insertion tool comprising:
-
a tool body having a distal portion configured to hold the implant on an outer implant surface, the distal portion having an inner lumen with an internal depth stop; and a plunger slidable within the inner lumen to engage and dispense the implant, the plunger having a stop configured to engage with the internal depth stop, wherein the engagement of the stop and the internal depth stop limits an insertion depth of the implant into the punctum.
-
-
30. An implant insertion tool for use with a lacrimal implant, the insertion tool comprising:
-
a tool body having a proximal handle, a distal end, and an axis therebetween, the tool body including; an implant receptacle releasably supporting, on at least one outer implant surface, the lacrimal implant relative to the handle, such that the lacrimal implant is advanceable distally into a canalicular lumen by manipulation of the handle; and a tissue-engagement stop surface, the stop surface being distally oriented and configured to engage an anteriorly oriented tissue surface to inhibit distal insertion of the lacrimal implant beyond a target insertion depth.
-
-
31. A lacrimal implant insertion system for treatment of one or more tissues near a punctum of a patient, the punctum disposed between a canalicular lumen and an anteriorly oriented tissue surface of the patient, the lacrimal implant system comprising:
-
a self-dilating lacrimal implant; and an insertion tool having a proximal handle, a distal implant receptacle, and an axis therebetween, the implant receptacle releasably supporting the lacrimal implant such that the lacrimal implant is advanceable distally into the canalicular lumen by manipulation of the handle, the insertion tool including a tissue-engagement stop surface, the stop surface being distally oriented and configured to engage the anteriorly oriented tissue surface so as to inhibit distal insertion of the lacrimal implant beyond a target insertion depth.
-
-
32. A method of inserting an implant into a punctum of a patient using an insertion tool, the method comprising:
-
advancing the implant distally into the punctum; engaging a tissue stop of the insertion tool against a tissue surface of the punctum so as to inhibit distal movement of the insertion tool; and detaching the implant from the insertion tool while the tissue stop engages the tissue surface and while the implant is aligned axially relative to the tissue stop so that the implant is implanted at a target depth within the canalicular lumen.
-
-
33. A method of inserting an implant into a punctum of a patient using an insertion tool, the method comprising:
-
placing a tissue stop of the insertion tool proximate the punctum; moving a plunger within the insertion tool forward, thereby inserting the implant into the punctum; and stopping the plunger movement when a stop on the plunger engages an internal depth stop of the insertion tool, wherein the engagement of the stop and internal depth stop limits the depth of insertion of the implant into the punctum.
-
-
34. An extraction tool for extraction of an implant from a punctum of a patient, the extraction tool comprising:
an extraction tool body having a distal portion, wherein the distal portion includes an extraction feature to engage a complimentary extraction feature of the implant.
-
35. An extraction tool for extraction of an implant from a punctum of a patient, the extraction tool comprising:
-
an extraction tool body having a distal portion; and a suction device configured to provide a suction force to the extraction tool body, wherein the distal portion of the extraction tool includes an inner lumen extending to a tip of the distal portion, and wherein the tip is configured to engage the punctum and apply the suction force to extract the implant.
