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.
