a distal flush port disposed within the interior space and in fluid communication with the lumen of the elongated outer sheath.

2. The medical device of claim 1 , further comprising a sheath adapter disposed within and axially movable within the interior space;

wherein the distal flush port is attached to the sheath adapter.

3. The medical device of claim 2 , wherein the elongated outer sheath is fixed to and extends distally from the sheath adapter.

4. The medical device of claim 2 , wherein the elongated inner member extends distally through the sheath adapter and into the lumen of the elongated outer sheath.

5. The medical device of claim 1 , wherein the distal flush port is configured to be directly accessible from an exterior of the handle housing through the distal aperture.

6. The medical device of claim 1 , wherein the proximal flush port is configured to be directly accessible from an exterior of the handle housing through the proximal aperture.

7. The medical device of claim 1 , wherein the elongated inner member is fixed in position relative to the handle housing.

8. The medical device of claim 1 , wherein the elongated outer sheath is axially movable relative to the handle housing.

9. The medical device of claim 1 , wherein the elongated inner member includes at least three lumens extending longitudinally through the elongated inner member.

10. The medical device of claim 1 , further comprising a diverter and a support body fixedly attached to a proximal end of the diverter;

wherein the diverter and the support body are fixed in position relative to the handle housing;

wherein the proximal flush port is attached to the support body.

11. The medical device of claim 10 , wherein the elongated inner member is fixed to and extends distally from the diverter.

12. The medical device of claim 10 , wherein support body includes two lumens extending longitudinally therethrough.

13. The medical device of claim 12 , wherein the proximal flush port is in fluid communication with the two lumens of the support body.

14. The medical device of claim 13 , wherein the elongated inner member includes at least three lumens extending longitudinally through the elongated inner member;

wherein at least two of the at least three lumens of the elongated inner member are in fluid communication with the proximal flush port.

15. A medical device, comprising:

a handle housing having a proximal end, a distal end, a longitudinal axis extending from the proximal end to the distal end, and an interior space therein;

wherein the handle housing includes a side wall defining the interior space and extending from the proximal end to the distal end, a proximal aperture extending through the side wall of the handle housing to the interior space, and a distal aperture extending through the side wall of the handle housing to the interior space;

an elongated outer sheath having a lumen therein extending distally from the distal end of the handle housing;

an elongated inner member extending distally through the distal end of the handle housing within the lumen of the elongated outer sheath;

a proximal flush port fixedly disposed within the interior space and in fluid communication with the elongated inner member;

a distal flush port movably disposed within the interior space and in fluid communication with the lumen of the elongated outer sheath; and

a control knob at the proximal end of the handle housing;

wherein rotating the control knob relative to the handle housing moves the distal flush port longitudinally within the interior space.

16. The medical device of claim 15 , wherein the elongated outer sheath is fixed in position relative to the distal flush port.

17. The medical device of claim 15 , wherein the elongated inner member is fixed in position relative to the proximal flush port.

18. The medical device of claim 15 , wherein fluid introduced into the proximal flush port passes through the elongated inner member and does not enter the lumen of the elongated outer sheath.

19. The medical device of claim 15 , wherein fluid introduced into the distal flush port passes through the lumen of the elongated outer sheath and does not enter the elongated inner member.

20. A medical device, comprising:

a handle housing having a proximal end, a distal end, and a longitudinal axis extending from the proximal end to the distal end;

wherein the handle housing includes a side wall having laterally-facing proximal and distal apertures extending therethrough;

an elongated outer sheath having a lumen therein extending distally from the distal end of the handle housing;

an elongated inner member extending distally through the distal end of the handle housing within the lumen of the elongated outer sheath;

a laterally-facing proximal flush port fixedly disposed within the handle housing and in fluid communication with the elongated inner member;

a laterally-facing distal flush port movably disposed within the handle housing and in fluid communication with the lumen of the elongated outer sheath; and

a control knob disposed about the proximal end of the handle housing;

wherein rotating the control knob about the handle housing moves the distal flush port relative to the handle housing in a direction parallel to the longitudinal axis.
