Apparatus and methods for accessing and sealing bodily vessels and cavities
Everting balloon systems and methods for using the same are disclosed herein. The systems can be configured to access and dilate body lumen and cavities. For example, the systems can be used to dilate the cervix and access the uterine cavity. The systems can also be used to occlude the cervix. The systems can also be used to occlude the urethra.
1. A method for treating a biological lumen comprising:
positioning a balloon adjacent to an opening of the biological lumen, wherein the balloon has a closed distal terminal end, and wherein the balloon is attached to a base comprising a leader;
delivering a pressurized media into the balloon with an inflation device, wherein the delivering comprises everting the balloon into the biological lumen, and wherein the everting comprises occluding the biological lumen;
detaching the inflation device from the balloon; and
pulling the balloon from the biological lumen after the detaching of the inflation device, and wherein pulling the balloon comprises pulling the leader.
2. The method of claim 1 , further comprising depressurizing the balloon, wherein the depressurizing comprises removing a plug from the base, and wherein the delivering a pressurized media comprises pressurizing the media with a motorized air pump, and wherein the balloon has a ridge.
3. The method of claim 1 , further comprising depressurizing the balloon, wherein the base comprises a valve, and wherein the depressurizing comprises opening the valve.
4. The method of claim 1 , further comprising depressurizing the balloon, wherein the depressurizing comprises pulling the leader.
5. The method of claim 1 , wherein leader comprises a string.
6. The method of claim 1 , wherein the balloon has a balloon lumen extending through a length of the balloon.
7. The method of claim 6 , further comprising occluding the balloon lumen with a plug.
8. The method of claim 1 , wherein the biological lumen comprises a urethra.
9. The method of claim 1 , wherein the delivering comprises inflating the balloon.
10. A method for treating a biological lumen comprising:
positioning a balloon adjacent to an opening of the biological lumen wherein the balloon has a closed distal terminal end, and wherein a leader extends from the balloon;
delivering a pressurized media into the balloon, wherein the delivering comprises everting the balloon into the biological lumen, and wherein the everting comprises occluding the lumen, wherein the everting comprises pressurizing and inflating; and
withdrawing the balloon from the biological lumen after the detaching of the inflation device, and wherein withdrawing the balloon comprises pulling the leader;
wherein the biological lumen comprises a urethra.
11. The method of claim 10 , wherein the leader comprises a string, and wherein the delivering of the pressurized media comprises delivering the pressurized media with a disengageable syringe.
12. A method for treating a biological lumen comprising:
positioning a balloon adjacent to an opening of the biological lumen, wherein the balloon has a closed distal terminal end, and wherein the balloon is attached to a leader;
delivering a pressurized media into the balloon with an inflation device, wherein the delivering comprises everting the balloon into the biological lumen, and wherein the everting comprises occluding the biological lumen;
detaching the inflation device from the balloon; and
translating the balloon from the biological lumen after the detaching of the inflation device, and wherein translating the balloon comprises pulling the leader.
13. The method of claim 12 , further comprising depressurizing the balloon, wherein the balloon is attached to a base, and wherein the depressurizing comprises removing a plug from the base.
14. The method of claim 12 , further comprising depressurizing the balloon, wherein the balloon is attached to a base comprising a valve, and wherein the depressurizing comprises opening the valve.
15. The method of claim 12 , further comprising depressurizing the balloon, wherein the balloon is attached to a base, and wherein the leader extends from the base, and wherein the depressurizing comprises pulling the leader, and wherein the balloon has a coating comprising an anti-infection agent.
16. The method of claim 12 , wherein the leader comprises a string, and wherein the delivering a pressurized media comprises pressurizing the media with a motorized air pump.
17. The method of claim 12 , wherein the balloon has a balloon lumen extending through a length of the balloon.
18. The method of claim 17 , further comprising occluding the balloon lumen with a plug.
19. The method of claim 12 , wherein the biological lumen comprises a urethra.
20. The method of claim 12 , wherein the delivering comprises inflating the balloon.
