Bronchus sealants and methods of sealing bronchial tubes
Bronchus sealants and methods of sealing bronchial tubes are provided. In general, the bronchus sealants and methods of sealing bronchial tubes can facilitate sealing of stapled bronchial tubes. In some embodiments, a reinforcement material can be introduced into a bronchial tube, and then the bronchial tube and the reinforcement material can be stapled using a surgical stapler. A sealant can be introduced into the bronchial tube and can harden therein, thereby helping to seal the bronchial tube where the bronchial tube was stapled. The sealant can be introduced into the bronchial tube before and/or after the stapling of the bronchial tube and the reinforcement material.
1. A surgical method, comprising:
transorally advancing a reinforcement material into a bronchial tube of a patient;
introducing a sealant into the bronchial tube and applying the sealant to the reinforcement material within the bronchial tube prior to the reinforcement material being fastened to the bronchial tube, the sealant transitioning from a first state to a second, harder state within the bronchial tube so as to secure the reinforcement material in a fixed position relative to the bronchial tube; and
after the sealant is applied to the reinforcement material, fastening the reinforcement material to the bronchial tube with a fastener;
wherein advancing the reinforcement material includes advancing a distal end of a scoping device into the bronchial tube and introducing the reinforcement material into the bronchial tube through the scoping device;
wherein introducing the sealant includes introducing the sealant into the bronchial tube through the scoping device with the sealant in the first state; and
wherein the scoping device has an end cap on the distal end thereof during the introduction of the sealant into the bronchial tube through the scoping device, and the scoping device does not have the end cap on the distal end thereof during the introduction of the reinforcement material into the bronchial tube through the scoping device.
2. The method of claim 1 , wherein fastening the reinforcement material includes stapling the bronchial tube and the reinforcement material that has been introduced into the bronchial tube.
3. The method of claim 2 , wherein a first component of the sealant is introduced and applied before the stapling of the bronchial tube and the reinforcement material, and a second component of the sealant is introduced and applied after the stapling of the bronchial tube and the reinforcement material.
4. The method of claim 1 , wherein the fastener is selected from the group consisting of staples, clips, sutures, and energy.
5. The method of claim 1 , wherein the fastener includes a staple, and fastening the reinforcement material includes stapling the bronchial tube and reinforcement material using a stapler located outside of the bronchial tube.
6. The method of claim 5 , wherein the stapler cuts the bronchial tube and the reinforcement material, and the method further comprises removing a cut portion of the bronchial tube and a cut portion of the reinforcement material from the patient's body.
7. A surgical method, comprising:
positioning a reinforcement material within a bronchial tube;
positioning a stapler outside the bronchial tube and using a location mechanism coupled to the stapler to identify a location of the reinforcement material within the bronchial tube; and
after identifying the location of the reinforcement material, stapling the bronchial tube and the reinforcement material with the stapler so as to form a staple line extending across the bronchial tube with the reinforcement material engaged within the staple line;
wherein an actuator coupled to the reinforcement material moves from a first state to a second, harder state after the stapling so as to facilitate sealing of the staple line.
8. The method of claim 7 , wherein the location mechanism includes a light, and using the location mechanism includes illuminating the light outside the bronchial tube.
9. The method of claim 7 , wherein the location mechanism includes a magnet, and using the location mechanism includes the magnet magnetically engaging a target located within the bronchial tube adjacent to the reinforcement material.
10. The method of claim 7 , wherein the reinforcement material comprises at least one of a mesh, a non-woven matrix, a film, a melt-blown non woven material, a felt material, a closed cell foam, an open-cell foam, a sponge, a braided suture, poliglecaprone, polyglactin, polydioxanone, collagen, oxidized cellulose, glycerol, glycolide, lactide, dioxanone, trimethylene carbonate, gut suture, polypropylene, polyethylene, polybutester fiber, stainless steel, nylon, polyester, silk, polyvinylidene difluoride, and polypropylene.
11. The method of claim 7 , wherein the actuator includes a biologic foam.
12. The method of claim 7 , wherein the reinforcement material irritates the bronchial tube.
13. The method of claim 7 , wherein the location mechanism includes a sensor, and using the location mechanism includes the sensor sensing a magnet located within the bronchial tube.
14. The method of claim 13 , wherein a grasper is used in positioning the reinforcement material within the bronchial tube, and the grasper has the magnet coupled thereto.
15. The method of claim 7 , wherein the stapler also cuts the bronchial tube and the reinforcement material.
16. A surgical method, comprising:
transorally advancing a reinforcement material into a bronchial tube of a patient;
introducing a sealant into the bronchial tube and applying the sealant to the reinforcement material within the bronchial tube prior to the reinforcement material being fastened to the bronchial tube, the sealant transitioning from a first state to a second, harder state within the bronchial tube so as to secure the reinforcement material in a fixed position relative to the bronchial tube; and
after the sealant is applied to the reinforcement material, fastening the reinforcement material to the bronchial tube with a fastener;
wherein advancing the reinforcement material includes advancing a distal end of a scoping device into the bronchial tube and introducing the reinforcement material into the bronchial tube through the scoping device;
wherein introducing the sealant includes introducing the sealant into the bronchial tube through the scoping device with the sealant in the first state; and
wherein the scoping device has a balloon at the distal end thereof that is configured to move between an inflated configuration and an uninflated configuration, the balloon being in the inflated configuration during the introduction of the sealant into the bronchial tube through the scoping device and the balloon being in the uninflated configuration during the advancement of the distal end of the scoping device into the bronchial tube.
17. The method of claim 16 , wherein the balloon is in the inflated configuration during the introduction of the reinforcement material into the bronchial tube through the scoping device.
18. The method of claim 16 , wherein fastening the reinforcement material includes stapling the bronchial tube and the reinforcement material that has been introduced into the bronchial tube.
19. The method of claim 16 , wherein the fastener is selected from the group consisting of staples, clips, sutures, and energy.
20. The method of claim 16 , wherein the fastener includes a staple, and fastening the reinforcement material includes stapling the bronchial tube and reinforcement material using a stapler located outside of the bronchial tube.
