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. ## Claims ### Claim 1 A kit for treatment of sinusitis through an implant device for implantation in a human to provide a fluid connection between a location in a lacrimal apparatus to a paranasal sinus through a fistula formed between the lacrimal apparatus and the paranasal sinus to provide direct medical access through the implant device from the lacrimal apparatus to the paranasal sinus, the kit comprising: a first surgical tool having a first working member configured to form an initial fistula; an implant device for implantation to fluidly connect a lacrimal apparatus to a paranasal sinus, the implant device comprising: a proximal end at a first longitudinal end of the implant device; a distal end at a second longitudinal end of the implant device that is longitudinally opposite the first longitudinal end; a conduit extending from adjacent the proximal end to adjacent the distal end; a first internal passage extending between the proximal end and the distal end and through the conduit, the first internal passage having a first end open at the proximal end and a second end open at the distal end; and a length of the implant device longitudinally along the implant device between the proximal end and the distal end in a range of from 8 millimeters to 50 millimeters; and wherein the conduit is constructed of polymeric material having a durometer (Shore A) in a range of from 50 to 100, and the implant device is configured to be implanted to fluidly connect the lacrimal apparatus to the paranasal sinus through the first internal passage of the implant device with the proximal end of the implant device disposed in the lacrimal apparatus with the first end of the first internal passage open to the lacrimal apparatus, the distal end disposed in the paranasal sinus with the second end of the first internal passage open to the paranasal sinus and the conduit disposed through an implantation fistula between the lacrimal apparatus and the paranasal sinus; a carrier for carrying and positioning the implant device for implantation during an implantation procedure, the carrier comprising: a second working member with a distal tip, the second working member being adapted to be disposed through the implantation fistula with the distal tip located in the paranasal sinus; a hand-manipulable handle connected to the second working member; and a second internal passage extending through the handle and the second working member to accommodate passage therethrough of a guide wire to guide the first surgical tool along the guide wire to the implantation fistula during an implantation procedure; wherein: the implant device is mountable on the carrier in a mounting position between the handle and the distal tip with the second working member disposed through the first internal passage and with the proximal end of the implant device disposed toward the handle and the distal end of the implant device disposed toward the distal tip of the second working member; and the carrier is disengageable from the implant device for implant placement of the implant device disposed through the implantation fistula. ### Claim 2 (depends on 1) A kit according to claim 1, comprising a guide wire that is passable through the second internal passage to guide the carrier to a location where the implant device is to be implanted. ### Claim 3 (depends on 1) A kit according to claim 1, wherein the implant device comprises a head adjacent the conduit at the proximal end of the implant device; and wherein the head comprises a flanged tissue engagement surface on a side of the head disposed toward the conduit and configured to engage tissue outside of and adjacent to the implantation fistula when the implant device is implanted. ### Claim 4 (depends on 3) A kit according to claim 3, wherein the head has a length dimension and a width dimension transverse to the length dimension with the length dimension being in a range of from 2 millimeters to 7 millimeters and the width dimension being in a range of from 2 millimeters to 5 millimeters. ### Claim 5 (depends on 4) A kit according to claim 4, wherein the head has a circular outer edge and the length dimension and the width dimension are equal. ### Claim 6 (depends on 1) A kit according to claim 1, wherein a length of the conduit is in a range of from 8 millimeters to 40 millimeters. ### Claim 7 (depends on 1) A kit according to claim 1, wherein the implant device comprises a plurality of apertures through a wall of the conduit providing fluid communication from outside of the conduit to the first internal passage through the conduit, and wherein at least some of the apertures are located along the length at least 5 millimeters from the proximal end. ### Claim 8 (depends on 1) A kit according to claim 1, wherein when the implant device is mounted in the mounting position the distal tip of the second working member is located at least 0.5 centimeter from the distal end of the implant device. ### Claim 9 (depends on 8) A kit according to claim 8, wherein when the implant device is mounted in the mounting position the distal tip of the second working member is located not more than 4 centimeters from the distal end of the implant device. ### Claim 10 (depends on 9) A kit according to claim 9, wherein when the implant device is mounted in the mounting position the distal tip of the second working member is located at least 0.75 centimeter from the proximal end of the implant device. ### Claim 11 (depends on 10) A kit according to claim 10, wherein when the implant device is mounted in the mounting position the distal tip of the second working member is located not more than 7 centimeters from the proximal end of the implant device. ### Claim 12 (depends on 1) A kit according to claim 1, wherein the distal tip of the second working member is blunt. ### Claim 13 (depends on 1) A kit according to claim 1, comprising a treatment composition including a drug for treating the paranasal sinus. ### Claim 14 (depends on 13) A kit according to claim 13, comprising a syringe containing the treatment composition. ### Claim 15 (depends on 13) A kit according to claim 13, wherein the treatment composition includes at least one drug selected from the group consisting of anti-inflammatories, antimicrobials, analgesics, mucolytics, antivirals, decongestants, steroids, antihistamines, antibiotics and anti-fungals. ### Claim 16 (depends on 13) A kit according to claim 13, wherein the treatment composition comprises an antibiotic and at least one drug selected from the group consisting of steroids and antihistamines. ### Claim 17 (depends on 1) A kit according to claim 1, wherein the first working member comprises a cutting instrument selected from the group consisting of a needle, cutting cannula and trocar. ### Claim 18 (depends on 17) A kit according to claim 17, wherein the first working member has a larger diameter than the second working member.
