Abstract

An insertion tool, systems, and methods for use with lacrimal implants are herein provided. An insertion tool is disclosed that includes an inserter tip with a static pin at a distal end configured to be placed in a bore of a lacrimal implant and a mechanical coupling to receive a handle at a proximal end of the inserter tip; and, a handle coupled to the inserter tip at a distal end of the handle and a plunger at a proximal end of the handle, wherein the plunger is configured to release the inserter tip from the handle. The static pin of the inserter tip is de-coupled from the lacrimal implant after placement in a lacrimal canaliculus without mechanical force from the insertion tool.

Core Innovation

The invention relates to a lacrimal implant insertion tool for placing a lacrimal implant at a punctum. An inserter tip includes a static pin at a distal end configured to be placed in a bore of the lacrimal implant, with a mechanical coupling configured to receive a handle at a proximal end of the inserter tip. The handle is coupled to the inserter tip at a distal end of the handle and includes a plunger at a proximal end of the handle, where the plunger is configured to release the inserter tip from the handle.

The invention further addresses how the static pin is managed relative to the implant during insertion. The system decouples the static pin from the implant in the canaliculus without applying mechanical force from the insertion tool, using a release mechanism that disengages the inserter tip from the handle. This provides a two-piece insertion tool concept in which the inserter tip functions with the handle for placement and is then released.

In related systems, a system for treatment of an eye includes the inserter tip having the static pin configured to be placed in a bore of a lacrimal implant, together with a mechanical coupling to receive a handle. The system additionally includes the lacrimal implant coupled to the static pin, and the lacrimal implant may include multiple member geometry with a bored member configured to receive the inserter static pin, including an angled intersection and defined first and second angle ranges.

Claims Coverage

The document provides two independent claims, one directed to a lacrimal implant insertion tool and one directed to a system for treatment of an eye.

Overall, the independent claim coverage centers on a lacrimal implant insertion tool with an inserter tip having a static pin for placement in a bore of the lacrimal implant and a mechanical coupling that receives a handle, together with a proximal plunger mechanism that releases the inserter tip from the handle. The independent system claim additionally includes a lacrimal implant coupled to the static pin as part of a system for treatment of an eye.
