Abstract

A medical device may include a handle housing having a side wall defining an interior space and proximal and distal apertures extending through the side wall, an elongated outer sheath, an elongated inner member, a proximal flush port disposed within the interior space and in fluid communication with the elongated inner member, and a distal flush port disposed within the interior space and in fluid communication with the elongated outer sheath. A control knob may be rotated to move the distal flush port within the interior space.

Claims

1. 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;

a rotatable control knob disposed about the proximal end of the handle housing operatively coupled to a longitudinally movable sheath adapter disposed within the handle housing;

an elongated outer sheath fixed to the sheath adapter, the outer sheath 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 a lumen of the outer sheath; and

a distal flush port in fluid communication with the lumen of the outer sheath, the distal flush port being disposed on the sheath adapter.

2. The medical device of claim 1, further comprising a proximal flush port disposed within the handle housing and in fluid communication with the inner member.

3. The medical device of claim 2, wherein the proximal flush port is accessible from an exterior of the handle housing.

4. The medical device of claim 3, wherein the proximal flush port is fixed in position relative to the handle housing.

5. The medical device of claim 1, wherein the control knob is configured to rotate about the longitudinal axis.

6. The medical device of claim 5, wherein rotation of the control knob about the longitudinal axis translates the distal flush port longitudinally within the handle housing.

7. The medical device of claim 6, wherein the distal flush port is translatable longitudinally within the handle housing along the inner member.

8. The medical device of claim 6, wherein the distal flush port is translatable longitudinally within the handle housing relative to the inner member.

9. The medical device of claim 1, wherein the handle housing includes a distal aperture extending through a side wall of the handle housing.

10. The medical device of claim 1, wherein the distal flush port is accessible from an exterior of the handle housing.

11. The medical device of claim 1, wherein the distal flush port opens laterally with respect to the longitudinal axis.

12. The medical device of claim 1, wherein the distal flush port is longitudinally movable between a proximal position and a distal position.

13. The medical device of claim 12, wherein the distal flush port is accessible from an exterior of the handle housing in the proximal position.

14. The medical device of claim 13, wherein the distal flush port is accessible through a distal aperture extending through a side wall of the handle housing in the proximal position.

15. The medical device of claim 1, further comprising a lead screw extending longitudinally within the handle housing, the lead screw being operatively connected to the control knob and the sheath adapter.

16. The medical device of claim 1, wherein the sheath adapter is disposed within the handle housing distal of the control knob.
