US Patent 12017023 Paranasal sinus fluid access implantation tools, assemblies, kits and methods

An implantation tool to implant a paranasal sinus fluid access implant device to fluidly connect the lacrimal apparatus in the orbit with a paranasal sinus has a securement mechanism reconfigurable from a securement configuration to secure the implant device to a mounting portion of a carrier member to a released configuration to release the implant device from the carrier member, and with a release mechanism disposed at least partially in an interior working space housed within the implantation tool. An implantation method with an approach through the palpebral fissure advances the implant device through a surgical route mostly under tension.
