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 delivering matter into the reproductive tract of a female comprising a cervical canal, the method comprising:
retracting a first catheter having a lumen and a distal lumen port, wherein an everting balloon is attached to the first catheter;
extending the first catheter, wherein extending the first catheter comprises extending at least a length of the everting balloon past the distal lumen port of the first catheter;
sliding a second catheter located in the first catheter, wherein the sliding comprises pulling the second catheter distally through the cervical canal by everting the everting balloon;
delivering an endoscope held by the second catheter into the reproductive tract of the female, and wherein the delivering comprises increasing the diameter of the cervix; and
sealing the cervical channel with the everting balloon wherein the sealing comprises occluding the entire cervical channel after the delivering of the endoscope.
2. The method of claim 1 , further comprising delivering a biopsy device.
3. The method of claim 1 , further comprising transporting a reproductive material through the first catheter into the uterine cavity, and wherein sealing the cervical channel comprises occluding the cervical channel with the everting balloon after transporting of the reproductive material.
4. A method for delivering matter into the reproductive tract of a female comprising a cervical canal, the method comprising:
retracting a first catheter having a lumen and a distal lumen port, wherein an everting balloon is attached to the first catheter;
extending the first catheter, wherein extending the first catheter comprises extending at least a length of the everting balloon past the distal lumen port of the first catheter;
sliding a second catheter located in the first catheter, wherein the sliding comprises pulling the econd catheter distally through the cervical canal by everting the everting balloon;
delivering an endoscope held by the second catheter into the reproductive tract of the female, wherein the delivering comprises increasing the diameter of the cervix; and
sealing the cervical channel with the everting balloon, wherein the sealing comprises occluding the entire cervical canal with the everting balloon after transporting a biopsy device to the uterine cavity.
5. The method of claim 4 , further comprising delivering a brush.
6. The method of claim 4 , further comprising fluidly sealing a distal lumen port of the second catheter with respect to the uterine cavity.
7. The method of claim 4 , further comprising inflating the everting balloon distal to the distal lumen port.
8. A method for delivering matter into the reproductive tract of a female comprising a cervical canal, the method comprising:
retracting a first catheter having a lumen and a distal lumen port, wherein an everting balloon is attached to the first catheter;
extending the first catheter, wherein extending the first catheter comprises extending at least a length of the everting balloon past a distal lumen port of the first catheter;
sliding a second catheter located in the first catheter, wherein the sliding comprises pulling the second catheter distally through the cervical canal by everting the everting balloon;
delivering a biopsy device held by the second catheter into the reproductive tract of the female, wherein the delivering comprises increasing the diameter of the cervix; and
sealing the cervical channel with the everting balloon, wherein the sealing comprises occluding the entire cervical channel after the delivering of the biopsy device.
9. The method of claim 8 , further comprising delivering a brush.
10. The method of claim 8 , further comprising fluidly sealing a distal lumen port of the second catheter with respect to the uterine cavity.
11. The method of claim 8 , further comprising inflating the everting balloon distal to the distal lumen port.
12. A method for delivering matter into the reproductive tract of a female comprising a cervical canal, the method comprising:
retracting a first catheter having a lumen and a distal lumen port, wherein an everting balloon is attached to the first catheter;
extending the first catheter, wherein extending the first catheter comprises extending at least a length of the everting balloon past a distal lumen port of the first catheter;
sliding a second catheter located in the first catheter, wherein the sliding comprises pulling the second catheter distally through the cervical canal by everting the everting balloon;
transporting a reproductive material through the first catheter into the uterine cavity;
delivering an endoscope held by the second catheter into the reproductive tract of the female, wherein the delivering comprises increasing the diameter of the cervix; and
sealing the cervical channel with the everting balloon, wherein the sealing comprises occluding the entire cervical channel after the delivering of the endoscope and occluding the cervical channel with the everting balloon after the transporting of the reproductive material.
13. The method of claim 12 , wherein at least a length of the everting balloon extends past the distal lumen port of the first catheter when the first catheter is in the extended configuration.
14. The method of claim 12 , further comprising a fallopian tube occluding device, wherein the second catheter is configured to deliver the fallopian tube occluding device.
15. The method of claim 12 , further comprising a handle configured to control the eversion of the everting balloon, wherein the handle is configured to control translation of the second catheter.
16. The method of claim 14 , further comprising a fallopian tube occluding device, wherein the second catheter is configured to deliver the fallopian tube occluding device.
17. The method of claim 14 , further comprising a handle configured to control the eversion of the everting balloon, wherein the handle is configured to control translation of the second catheter.
18. The method of claim 15 , further comprising a handle configured to control the eversion of the everting balloon, wherein the handle is configured to control translation of the second catheter.
19. The method of claim 17 , further comprising a handle configured to control the eversion of the everting balloon, wherein the handle is configured to control translation of the second catheter.
