Abstract

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.

Claims

1. A system for accessing a cervical canal adjacent to a uterine cavity comprising:

a first catheter;

a second catheter radially inside in the first catheter, wherein the second catheter is translatable with respect to the first catheter;

a first balloon attached at a first end to the first catheter, and wherein the first balloon is attached at a second end to the second catheter;

a second balloon attached to the second catheter; and

a connector having a first connector port, and a second connector port, wherein the second catheter extends through the first connector port and the second connector port, wherein the connector further has a third connector port, and wherein the connector and second catheter have a first configuration and a second configuration, and wherein in the first configuration, the third connector port is in fluid communication with a volume between the first catheter and the second catheter, and wherein in the second configuration the third connector port is in fluid communication with a lumen in the second catheter.

2. The system of claim 1, wherein the second balloon is attached at a first end to the second catheter and at a second end to the second catheter, and wherein the second catheter has a port inside the second balloon.

3. The system of claim 1, wherein the connector further comprises a first gasket having a first gasket port, and a second gasket having a second gasket port, and wherein the second catheter extends through the first gasket port and the second gasket port.

4. The system of claim 1, wherein the second catheter has a first length having a first diameter, and a second length having a second diameter, and wherein the first diameter is larger than the second diameter.

5. The system of claim 4, wherein the second catheter has a port on the lateral side of the second catheter in the second length, and wherein the port is in fluid communication with the second balloon.

6. A system for accessing a cervical canal adjacent to a uterine cavity comprising:

a first catheter;

a second catheter radially inside in the first catheter;

an everting balloon;

a dilation balloon;

a handle comprising a first control, a second control, and a third control, wherein the first control is configured to translate the second catheter, and wherein the second control is configured to inflate the everting balloon, and wherein the third control is configured to inflate the dilation balloon; and

a connector having a first connector port, and a second connector port, wherein the second catheter extends through the first connector port and the second connector port, wherein the connector further has a third connector port, and wherein the connector and second catheter have a first configuration and a second configuration, and wherein in the first configuration, the third connector port is in fluid communication with a volume between the first catheter and the second catheter, and wherein in the second configuration the third connector port is in fluid communication with a lumen in the second catheter.

7. The system of claim 6, wherein the everting balloon is attached at a first end to the first catheter and at a second end to the second catheter;

and wherein the dilation balloon is inside of the everting balloon when the dilation balloon is in a deflated configuration.

8. The system of claim 6, wherein the second catheter is translatable with respect to the first catheter.
