Apparatus and methods for accessing and sealing bodily vessels and cavities

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.

We claim: 
     
         1 . A system for delivering matter into the 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;   an endoscope, wherein the second catheter is configured to deliver the endoscope.
