Abstract
A method and system of providing therapy to a patient's uterus. The method can include the steps of inserting a uterine ablation device into the uterus, expanding a distal anchor, inflating a proximal balloon to pull the distal anchor proximally and seat the distal anchor against the internal os of the uterus, inflating a central balloon to seal the cervix, delivering vapor from the uterine ablation device into the uterus, and condensing the vapor on tissue within the uterus. The system can include a cervical collar adapted to place a distal portion of the device within the uterus when the cervical collar contacts an external os of the cervix.
Claims (30)
1. A uterine device, comprising:
a shaft sized and configured to access a uterus of a patient, the shaft being coupled to a fluid source;
fluid delivery ports disposed on a distal portion of the shaft;
a distal balloon positioned proximally on the shaft from the fluid delivery ports;
a central balloon positioned proximally to the distal balloon, the central balloon configured to contact an internal os and a cervical canal of the patient when the distal balloon is positioned in the uterus against the internal os;
a proximal balloon positioned proximally to the central balloon and spanning a first portion of the cervical canal and a second portion of a vagina of the patient when the distal balloon is positioned in the uterus against the internal os and the central balloon is positioned within the cervical canal; and
a controller operably coupled to the distal balloon, the central balloon, and the proximal balloon, the controller configured to fully inflate the proximal balloon after inflating the distal balloon such that the proximal balloon is fully inflated along the first portion of the cervical canal and the second portion of the vagina, wherein the uterine device is configured such that inflation of the proximal balloon causes the uterine device to move proximally to position the distal balloon against the internal os,
wherein the uterine device is configured to deliver a heated vapor to the uterus.
2. The uterine device of claim 1 , further comprising a filter portion disposed on the distal portion of the shaft.
3. The uterine device of claim 2 , wherein the filter portion is configured to prevent removal of tissue, blood clots, or debris from the uterus.
4. The uterine device of claim 2 , wherein the filter portion comprises a non-expandable filter comprising a polymeric mesh.
5. The uterine device of claim 4 , wherein the non-expandable filter has a pore size of approximately 250 microns to 350 microns.
6. The uterine device of claim 4 , further comprising one or more coils configured to support the non-expandable filter.
7. The uterine device of claim 1 , wherein the central balloon has a length along the shaft of approximately 15 mm to 25 mm.
8. The uterine device of claim 1 , wherein the distal balloon has a length along the shaft of approximately 3 mm to 10 mm.
9. The uterine device of claim 1 , wherein the proximal balloon has a length along the shaft of approximately 50 mm to 70 mm.
10. The uterine device of claim 1 , wherein inflating the proximal balloon after inflating the distal balloon generates a compression force that causes the distal balloon to engage against the internal os of the patient.
11. The uterine device of claim 1 , wherein inflating the proximal balloon after inflating the distal balloon generates a compression force that pulls the uterine device proximally.
12. The uterine device of claim 1 , wherein the central balloon does not extend into the uterus of the patient or into a vagina of the patient when inflated.
13. The uterine device of claim 1 , wherein the controller is configured to inflate the central balloon after inflating the proximal balloon.
14. The uterine device of claim 1 , wherein the fluid delivery ports comprise at least one vapor delivery port and at least one vapor return port.
15. The uterine device of claim 1 , wherein the shaft comprises a vapor delivery lumen and a vapor return lumen.
16. The uterine device of claim 1 , wherein the shaft comprises:
a distal balloon inflation lumen configured to provide fluid to the distal balloon to inflate the distal balloon;
a central balloon inflation lumen configured to provide fluid to the central balloon to inflate the central balloon; and
a proximal balloon inflation lumen configured to provide fluid to the proximal balloon to inflate the proximal balloon.
17. The uterine device of claim 1 , wherein the controller is further configured to control delivery of the heated vapor through the fluid delivery ports.
18. The uterine device of claim 1 , further comprising a cervical collar positioned along the shaft.
19. The uterine device of claim 1 , further comprising a pressure sensor configured to measure a pressure within the uterus of the patient.
20. The uterine device of claim 1 , wherein the first portion of the cervical canal corresponds to a majority of a length of the cervical canal, and wherein the uterine device is configured such that after the controller has fully inflated the proximal balloon, and when the distal balloon is positioned against the internal os, the proximal balloon is inflated along the majority of the length of the cervical canal.
