摘要:
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.
摘要:
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.
摘要:
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.

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.
摘要:
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. A method of manufacture includes modifying a preliminary form, which may include roughening a smooth surface and/or enlarging a preliminary form for the head including a preliminary form for the concave undercut portion. of the head.

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.
