International Classification:

A61F 9/007
B29D 23/00

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.

International Classification:

A61M 27/00
A61F 9/007
A61B 17/11
A61M 3/02
A61M 31/00

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.

International Classification:

A61F 9/007

Abstract:

Apparatuses, tools and kits are directed to fluid manipulations in relation to a paranasal sinus through a paranasal sinus access implant device () 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 () has an engagement structure () insertable into the palpebral fissure to engage a head of the implant device.
