An implantation tool (300, 400) to implant a paranasal sinus fluid access implant device with an internal fluid communication passage through an artificial, surgical path between a lacrimal apparatus in the orbit and a paranasal sinus in an implantation procedure to provide direct fluid communication access through the internal passage from the lacrimal apparatus in the orbit to the paranasal sinus, the implantation tool comprising: a carrier member (306, 406) configured to carry the implant device on a mounting portion (308, 408) of the carrier member in a mounted orientation to position the implant device in an implantation position through the surgical path from an approach through the palpebral fissure during the implantation procedure; a securement mechanism (340, 342, 344, 346, 418, 420, 440) to secure the implant device in the implantation orientation on the carrier member to carry the implant device to the implantation position during the implantation procedure, the securement mechanism being reconfigurable from a securement configuration to secure the implant device to the mounting portion of the carrier member in the implantation orientation to a released configuration to release the implant device from securement to the carrier member to permit withdrawal of the carrier member relative to the implant device to leave the implant device implanted in the implantation position during the implantation procedure, wherein the securement mechanism comprises at least one securement member (340, 418) positioned to extend over and press against an exterior portion of the implant device in the implantation orientation when the securement mechanism is in the securement configuration; a handle portion (304, 404) connected with the carrier member and configured to remain outside of the surgical path during the implantation procedure and being manipulable by a medical practitioner to direct implantation of the implant device during the implantation procedure; internal working space housed within at least a portion of the handle portion and at least a portion of the carrier member; a release mechanism (310, 312, 318, 322, 352, 410, 414, 456) disposed at least in part in the internal working space and manipulable to reconfigure the securement mechanism from the securement configuration to the released configuration. a carrier member (306, 406) configured to carry the implant device on a mounting portion (308, 408) of the carrier member in a mounted orientation to position the implant device in an implantation position through the surgical path from an approach through the palpebral fissure during the implantation procedure; a securement mechanism (340, 342, 344, 346, 418, 420, 440) to secure the implant device in the implantation orientation on the carrier member to carry the implant device to the implantation position during the implantation procedure, the securement mechanism being reconfigurable from a securement configuration to secure the implant device to the mounting portion of the carrier member in the implantation orientation to a released configuration to release the implant device from securement to the carrier member to permit withdrawal of the carrier member relative to the implant device to leave the implant device implanted in the implantation position during the implantation procedure, wherein the securement mechanism comprises at least one securement member (340, 418) positioned to extend over and press against an exterior portion of the implant device in the implantation orientation when the securement mechanism is in the securement configuration; a handle portion (304, 404) connected with the carrier member and configured to remain outside of the surgical path during the implantation procedure and being manipulable by a medical practitioner to direct implantation of the implant device during the implantation procedure; internal working space housed within at least a portion of the handle portion and at least a portion of the carrier member; a release mechanism (310, 312, 318, 322, 352, 410, 414, 456) disposed at least in part in the internal working space and manipulable to reconfigure the securement mechanism from the securement configuration to the released configuration.
