Abstract: An implantation tool for implanting a paranasal sinus fluid access implant device through a surgical path between a lacrimal apparatus in an orbit and a paranasal sinus in an implantation procedure to provide direct fluid communication access from the lacrimal apparatus in the orbit to the paranasal sinus through an internal passage of the implant device. The implantation assembly comprises the implant device and an implantation tool wherein the implant device is mounted in a mounting orientation on a mounting portion of a carrier member of the implantation tool with a securement mechanism of the implantation tool in a securement configuration. The securement mechanism is reconfigurable to a released configuration to release the implant device from securement to the mounting portion of the carrier member.

Abstract: 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.

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: Described herein are implantable devices, delivery systems and surgical methods for creating a barrier that may be deployed into a digestive system organ to block the biochemical and/or neurohormonal systems thereby providing therapeutic benefit ideally treating diabetes mellitus and obesity. The device for creating a barrier in the digestive system organ may include a wall or conduit whether impermeable or porous at varying degrees. Method of surgical delivery for the device described herein may be conducted through open, laparoscopic, minimally invasive, or endoscopic means. The device may be temporarily secured on a novel delivery system enabling the methods described. The device may be secured to the digestive organ allowing natural biomechanical motion (peristaltic motion) of the digestive system without untoward effects.
