Abstract

Various embodiments of a system for priming a catheter assembly are disclosed herein. For example, the system can include a catheter assembly including an elongate body and an operative device coupled thereto. The system can also include a priming vessel configured to receive insertion of the operative device therein. The priming vessel can include a proximal portion secured to the distal portion of the elongate body such that the elongate body is in fluid communication with the priming vessel. The priming vessel can also include a distal end through which air is expelled when a fluid is channeled through the elongate body and into the priming vessel to expel air from within the catheter assembly.

Claims (26)

1. A system for priming a catheter assembly, the system comprising:

a catheter assembly comprising:

an elongate body comprising a distal portion; and

an operative device coupled at the distal portion; and

a priming vessel configured to be disposed around the elongate body and to receive insertion of the operative device therein, the priming vessel comprising:

a proximal portion secured to the distal portion of the elongate body such that the elongate body is in fluid communication with the priming vessel; and

a distal end through which air is expelled when a fluid is channeled through the elongate body and into the priming vessel to expel air from within the catheter assembly.

2. The system of claim 1 , wherein the priming vessel comprises a primer housing configured to house the operative device therein.

3. The system of claim 2 , wherein the primer housing is configured to house the distal portion of the elongate body therein.

4. The system of claim 2 , wherein the primer housing comprises a funnel portion, wherein an inner diameter of the primer housing decreases from proximal to distal within the funnel portion.

5. The system of claim 4 , wherein the funnel portion is configured to collapse the operative device to a stored configuration when the operative device is moved proximal relative to the primer housing.

6. The system of claim 2 , further comprising a sealing cap coupled at the proximal end of the primer housing, wherein the sealing cap is configured to seal the priming vessel for priming.

7. The system of claim 6 , further comprising a threaded connector configured to couple the sealing cap to the primer housing.

8. The system of claim 6 , wherein the sealing cap is configured to prevent airflow into the elongate body and configured to prevent flow of a priming fluid from the proximal end of the primer housing.

9. The system of claim 6 , wherein the sealing cap comprises a sealing recess at a distal end of the sealing cap configured to allow the elongate body to pass through the sealing cap.

10. The system of claim 2 , wherein the priming vessel comprises a gas permeable membrane coupled the distal end of the priming vessel to allow air to escape from the priming vessel during priming.

11. The system of claim 2 , wherein the operative device comprises an impeller assembly comprising an impeller and an expandable cannula positioned about the impeller.

12. The system of claim 11 , wherein the impeller is expandable.

13. The system of claim 11 , wherein the expandable cannula in fluid operation with the impeller.

14. The system of claim 2 , further comprising:

an infusion system configured to supply fluid to the catheter assembly, wherein the infusion system comprises an interface body; and

a console housing coupled to the infusion system, wherein the console housing comprises an interface aperture configured to receive the interface body therein.

15. The system of claim 14 , wherein the interface body comprises:

an occlusion bed;

a tube segment mounted on the interface body near the occlusion bed; and

an electrical component.
