Paranasal sinus access implant devices and related products and methods |
| 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. 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. |
