In one aspect, the medical device includes a catheter assembly. The catheter assembly includes a first catheter having a proximal end, a distal end, and a lumen disposed therethrough and a second catheter slidably disposed within the lumen of the first catheter, the second catheter having a distal end and a lumen disposed therethrough. The second catheter is moveable from a first position to a second position. A cervical seal is connected to the first catheter and the second catheter. A handle is engaged with the catheter assembly. In the first position, the cervical seal has a first outer diameter. In the second position, the cervical seal has a second outer diameter greater than the first outer diameter to create a seal in the cervix. ## Claims ### Claim 1 A medical device, comprising: a catheter assembly, the catheter assembly comprising: a first catheter having a proximal end, a distal end, and a lumen disposed therethrough; a second catheter slidably disposed within the lumen of the first catheter, the second catheter having a distal end and a lumen disposed therethrough, the second catheter being moveable from a first position to a second position; a cervical seal connected to the first catheter and the second catheter; a handle engaged with the catheter assembly; where in the first position, the cervical seal has a first outer diameter and where in the second position, the cervical seal has a second outer diameter greater than the first outer diameter. ### Claim 2 (depends on 1) The medical device of claim 1, where the cervical seal has a bulb-like configuration. ### Claim 3 (depends on 1) The medical device of claim 1, where the first outer diameter of the cervical seal ranges from about 3 mm to about 5 mm. ### Claim 4 (depends on 1) The medical device of claim 1, where the second outer diameter of the cervical seal ranges from about 9 mm to about 12 mm. ### Claim 5 (depends on 1) The medical device of claim 1, where the cervical seal is integral with the first catheter. ### Claim 6 (depends on 1) The medical device of claim 1, where the cervical seal comprises a plurality of folds. ### Claim 7 (depends on 1) The medical device of claim 1, where the second catheter is coaxially positioned within the first catheter. ### Claim 8 (depends on 1) The medical device of claim 1, where a proximal end of the cervical seal is connected to the first catheter and a distal end of the cervical seal is connected to the second catheter. ### Claim 9 (depends on 1) The medical device of claim 1, where an opening is disposed in the distal end of the second catheter distal of the seal. ### Claim 10 (depends on 1) The medical device of claim 1, where the handle includes a switch configured to move the second catheter between the first position to the second position. ### Claim 11 (depends on 1) The medical device of claim 1, where the handle includes a port for introducing fluid. ### Claim 12 A medical device, comprising: a catheter assembly, the catheter assembly comprising: a first catheter having a lumen disposed therethrough; a second catheter slidably disposed within the lumen of the first catheter, the second catheter having a distal end and a lumen disposed therethrough, the second catheter being moveable from a first position to a second position; a cervical seal connected to the first catheter and the second catheter, the cervical seal having a frame disposed within an interior surface; an opening disposed in the distal end of the second catheter distal of the cervical seal, and a handle engaged with the catheter assembly, the handle comprising a switch in communication with the second catheter and a port in fluid communication with the lumen of the second catheter and the opening in the distal end of the second catheter; where the cervical seal has an expanded configuration and a compressed configuration and where the outer diameter of the cervical seal in the compressed configuration is greater than the outer diameter of the cervical seal in the expanded configuration. ### Claim 13 (depends on 12) The medical device of claim 12, where the cervical seal has a bulb-like configuration. ### Claim 14 (depends on 12) The medical device of claim 12, where the outer diameter of the cervical seal in the expanded configuration ranges from about 3 mm to about 5 mm. ### Claim 15 (depends on 12) The medical device of claim 12, where the outer diameter of the cervical seal in the compressed configuration ranges from about 9 mm to about 12 mm. ### Claim 16 (depends on 12) The medical device of claim 12, where the frame comprises a plurality of ribs extending longitudinally about the inner surface of the seal. ### Claim 17 (depends on 12) The medical device of claim 12, where the frame is integral with the bulb. ### Claim 18 (depends on 12) The medical device of claim 12, where a proximal end of the cervical seal is connected to the first catheter and a distal end of the cervical seal is connected to the second catheter distal of the opening. ### Claim 19 (depends on 12) The medical device of claim 12, where the cervical seal is in the expanded configuration when the second catheter is in the first position and where the cervical seal is in the compressed configuration when the second catheter is in the second position. ### Claim 20 A medical device, comprising: a coaxial catheter assembly, the catheter assembly comprising: a first catheter having a distal end and a lumen disposed therethrough; a second catheter slidably disposed within the lumen of the first catheter, the second catheter having a distal end and a lumen disposed therethrough; a cervical seal having a bulb-like configuration connected to the first catheter and the second catheter, the cervical seal configured to occlude the internal os of a cervix; an opening disposed in the distal end of the second catheter distal of the seal, and a handle engaged with the catheter assembly, the handle comprising a switch in communication with the second catheter and a port in fluid communication with the lumen of the second catheter and the opening in the distal end of the second catheter; where the cervical seal has an expanded configuration when the second catheter is in a first position, the expanded configuration having a first outer diameter, where the cervical seal has an compressed configuration when the second catheter is in a second position, the compressed configuration having a second outer diameter greater than the first outer diameter, and where the handle comprises a switch in communication with the second handle configured to move the second catheter within the lumen of the first catheter between the first position and the second position.
