Abstract

Various embodiments of a fluid handling system are disclosed herein. For example, the fluid handling system can include a catheter assembly and a console configured to control the operation of the catheter assembly. A removable interface member can be configured to provide fluid and electrical communication between the catheter assembly and the console.

First claim

What is claimed is:

1 . A fluid handling system, the system comprising:
a housing comprising:
one or more pumps;
a controller configured to operate the pump(s); and
a catheter assembly comprising:
a catheter body having a proximal portion and an operative device at a distal portion; and
an infusion system in fluid communication with the proximal portion of the catheter body, the infusion system comprising a closure member configured to be separate from the housing in a first state and to at least partially secure the infusion system to the housing in a second state, wherein upon engagement of the closure member with the housing in the second state, the infusion system is operably engaged with the pump(s).

2 . The system of claim 1 , wherein the housing comprises an aperture, and wherein the closure member engages with the housing when a portion of the closure member is inserted into the aperture.

3 . The system of claim 2 , wherein the closure member is configured to substantially secure the infusion system to the housing in a third state.

4 . The system of claim 3 , wherein the closure member is configured to substantially secure the infusion system to the housing when the closure member is rotated relative to the housing.

5 . The system of claim 3 , wherein the housing comprises a disengagement member, the disengagement member configured to move the closure member from the third state to the second state such that the closure member partially secures the infusion system to the housing.

6 . The system of claim 1 , wherein upon engagement of the closure member with the housing in the second state, an electrical connection is formed between the housing and an electrical component of the closure member.

7 . The system of claim 6 , wherein the electrical connection is formed substantially at the same time that the infusion system becomes operably engaged with the pump(s).

8 . The system of claim 6 , wherein the catheter assembly further comprises a motor assembly in electrical communication with the electrical component of the closure member.

9 . The system of claim 6 , wherein the catheter assembly further comprises one or more sensors in electrical communication with the electrical component of the closure member.

10 . The system of claim 1 , wherein the infusion system comprises:
a waste line in fluid communication with the catheter body and configured to convey waste fluid out of the catheter assembly; and a first infusate line in fluid communication with the catheter body and configured to supply fluid into the catheter assembly.

11 . The system of claim 10 , wherein the catheter assembly further comprises an elongate body, the catheter body disposed within the elongate body, and wherein the infusion system comprises a second infusate line in fluid communication with the elongate body.

12 . The system of claim 11 , wherein the second infusate line is configured to supply fluid between the elongate body and the catheter body.

13 . A method for priming a catheter assembly, the catheter assembly comprising an elongate body and an operative device, the method comprising:
inserting the operative device of the catheter assembly into a priming vessel; securing a proximal portion of the priming vessel to a distal portion of the elongate body, such that the elongate body is in fluid communication with the priming vessel; and delivering fluid through the elongate body and the priming vessel to expel air within the catheter assembly.

14 . The method of claim 13 , further comprising removing the priming vessel from the catheter assembly.

15 . The method of claim 14 , further comprising, after removing the priming vessel, inserting the operative device of the catheter assembly into a vascular system of a patient.

16 . The method of claim 13 , further comprising providing relative movement between the priming vessel and the operative device to collapse the operative device to a stored configuration.
