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.
Claims18
A system for biopsying matter from a reproductive tract of a female comprising:
- a first catheter having a lumen and a distal lumen port, wherein the first catheter has a retracted configuration and an extended configuration;
- an everting balloon attached to the first catheter, wherein at least a length of the everting balloon extends past a distal end of the first catheter when the first catheter is in the extended configuration;
- a second catheter slidably located in the first catheter, and wherein the second catheter has a lateral port;
- a biopsy element, wherein the second catheter is configured to deliver the biopsy element;
- 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.

A system for sampling matter from a reproductive tract of a female comprising:
- a first catheter having a lumen and a distal lumen port, wherein the first catheter has a retracted configuration and an extended configuration;
- an everting balloon attached to the first catheter, wherein at least a length of the everting balloon extends past a distal end of the first catheter when the first catheter is in the extended configuration;
- a second catheter slidably located in the first catheter, and wherein the second catheter has a lateral port;
- a first sampling device, wherein the second catheter is configured to deliver the first sampling device;
- 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 more elements
A system for biopsying matter from a reproductive tract of a female comprising:
- a first catheter having a first catheter lumen, wherein the first catheter has a retracted configuration and an extended configuration;
- a second catheter slidably located in the first catheter, wherein the second catheter has a second catheter lumen and a second catheter distal port on a lateral side of the second catheter;
- a suction source in fluid communication with the second catheter lumen and the second catheter distal port;
- an everting balloon attached to the first catheter, wherein at least a length of the everting balloon extends past a distal end of the first catheter when the second catheter is in the extended configuration;
- wherein the second catheter is configured to deliver the second catheter distal port to the reproductive tract;
- and
- wherein the everting balloon covers the second catheter distal port when the second catheter is in a retracted configuration;
- 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.
