Abstract: An implant device is configured to be implanted in a fistula to fluidly connect the lacrimal apparatus and a paranasal sinus. A surgical tool has an implant the implant device mounted on a carrier. Various methods involve a fistula between the lacrimal apparatus and a paranasal sinus. A kit includes an entry device for use to form a fistula and an implant tool for use to implant an implant device following formation of a fistula.

Abstract: Access to a paranasal sinus is provided through implantation of an implant device with a conduit of the implant device disposed through a fistula surgically-formed between a location in the lacrimal apparatus and a paranasal sinus. As implanted, the implant device has a proximal end disposed in the lacrimal apparatus in the orbit, a distal end disposed in the paranasal sinus and an internal passage that provides fluid communication between the lacrimal apparatus in the orbit and the paranasal sinus.

Abstract: A paranasal sinus access implant device may include one or more material or geometric features that may enhance performance of one or more portions of the implant device, for example an exposed surface including an antimicrobial agent. Various products and methods may include or use such an implant device.

Abstract: A paranasal sinus access implant device includes a head to be disposed in a location in the lacrimal apparatus and a conduit extending into a paranasal sinus when the implant device is implanted to provide a fluid communication path between the lacrimal apparatus and the paranasal sinus through an internal passage through the implant device. The head has a perimeter transverse to a longitudinal axis of the implant device and a flanged portion of the head extending 360 degrees around the axis. A side of the flanged portion is disposed toward and engages tissue in the lacrimal apparatus when the implant device is implanted. The head includes a concave undercut portion on the distal side of the flanged portion, with the concave undercut extending 360 degrees around the axis within the perimeter of the head.

Abstract: A paranasal sinus access implant device to provide an artificial fluid path in fluid communication with the lacrimal apparatus may be implanted through a fistula opening into the lacrimal apparatus. The implant device may have a conduit with a first longitudinal portion having a larger minimum wall thickness than a minimum wall thickness of a second a second longitudinal portion of the conduit located distal of the first longitudinal portion. Various kits may include a paranasal sinus access implant device and one of more other components for a procedure involving implantation. A method involves use of a cutting tool to cut away tissue to prepare a fistula sized for implantation.

Abstract: Apparatuses, tools and kits are directed to fluid manipulations in relation to a paranasal sinus through a paranasal sinus access implant device (906) that provides fluid communication between the lacrimal apparatus in the orbit and a paranasal sinus. An implant device has a proximal head and a conduit distal of the head, with the conduit having a first longitudinal portion having a larger minimum wall thickness than a minimum wall thickness of a second a second longitudinal portion of the conduit located distal of the first longitudinal portion. A paranasal sinus fluid manipulation tool (900) has an engagement structure (904) insertable into the palpebral fissure to engage a head of the implant device.

Abstract: An implant device to provide an artificial fluid path in fluid communication with the lacrimal apparatus is implanted through a fistula opening into the lacrimal apparatus using a working member disposed through the implant device and a break-away sheath. Implantation kits and tool assemblies including the working member, implant device and break-away sheath facilitate implantation of the implant device.
