Abstract

Interventional catheter assemblies, operating systems and adaptive interface components allow operation of a variety of interventional catheter assemblies, including infusion catheters, aspiration catheters and interventional catheters that provide both infusion and aspiration, using a common control console housing infusion and aspiration systems. Adaptive tubing cassettes having a handle and one or more preformed tubing loops route aspiration and/or infusion tubing in a predetermined configuration to mate with aspiration and infusion systems on a control console.

First claim

We claim:

1. An adaptive tubing cassette for use in connection with an interventional catheter assembly and a control console, comprising:
a cassette housing having a tubing side and a handle side;
a first preformed tubing loop mounted to and extending from the tubing side of the cassette housing;
a second preformed tubing loop mounted to and extending from the tubing side of the cassette housing;
a handle positioned along the handle side of the cassette housing, the handle including a grasping portion;
a mating member disposed along the handle side of the cassette housing;
wherein the handle side of the cassette housing is free of tubing loops so that the mating member can mate and interlock with an interface region of a control console; and
wherein the first preformed tubing loop is configured to engage a first peristaltic pump of the control console at a first pressure and the second preformed tubing loop is configured to engage a second peristaltic pump of the control console at a second pressure, the first pressure being different than the second pressure,
wherein the first preformed tubing loop comprises a stiffer tubing material than that of the second preformed tubing loop.

2. The adaptive tubing cassette of claim 1 , wherein each of the preformed tubing loops forms a U-shaped loop.

3. The adaptive tubing cassette of claim 1 , wherein the preformed tubing loops extend from the handle in the same direction in a side-by-side arrangement.

4. The adaptive tubing cassette of claim 1 , wherein the first preformed tubing loop comprises a thicker walled tubing material than that of the second preformed tubing loop.

5. The adaptive tubing cassette of claim 1 , wherein the first preformed tubing loop has a larger outer diameter than that of the second preformed tubing loop.

6. The adaptive tubing cassette of claim 1 , wherein the first preformed tubing loop extends a greater distance from an edge of the handle than the second preformed tubing loop.

7. The adaptive tubing cassette of claim 1 , wherein the grasping portion is oriented for grasping on a surface substantially orthogonal to a plane of the preformed tubing loops.

8. The adaptive tubing cassette of claim 1 , wherein the first preformed tubing loop is an infusion tubing loop and the second preformed tubing loop is an aspiration tubing loop.

9. The adaptive tubing cassette of claim 1 , additionally comprising an interface component comprising a data storage device.

10. The adaptive tubing cassette of claim 1 , additionally comprising an interface component providing authentication and/or operating instructions protocols.

11. An interventional catheter assembly, comprising:
a control console including a first peristaltic pump and a second peristaltic pump;
a catheter assembly including a catheter control spaced apart from the control console, an aspiration tube extending from the catheter control, an infusion tube extending from the catheter control, and an elongated, flexible catheter sized and configured for insertion into a patient and incorporating aspiration and/or infusion lumen(s) providing fluidic communication to a distal end of the flexible catheter;
an adaptive tubing cassette coupled to the aspiration tube and coupled to the infusion tube, the adaptive cassette having a handle component incorporating an interface region adapted to mount stably in a mating interface region of the control console and a preformed tubing section mounted to and extending from the handle component, wherein the handle component includes at least one recess and a grasping portion adjacent the recess, and wherein the preformed tubing section is adapted to mount stably in a tubing receiving pathway of the first and second peristaltic pumps provided in connection with the control console;
wherein the preformed tubing section comprises first and second preformed tubing loops mounted to and extending from the handle component;
wherein the first preformed tubing loop comprises a thicker walled tubing material than that of the second preformed tubing loop.

12. The interventional catheter assembly of claim 11 , wherein the first and second preformed tubing loops have different dimensions and different tubing properties.

13. The interventional catheter assembly of claim 12 , wherein the preformed tubing loops extend from the handle component in the same direction in a side-by-side arrangement.

14. The interventional catheter assembly of claim 11 , additionally comprising an electrical cable that, when interfaced with a control console, provides electrical power to the interventional catheter assembly.

15. A tubing cassette, comprising:
a housing including a first side;
a first preformed tubing loop mounted to and extending from the first side of the housing; and
a second preformed tubing loop mounted to and extending from the first side of the housing;
wherein the first preformed tubing loop is configured to engage a first peristaltic pump and the second preformed tubing loop is configured to engage a second peristaltic pump;
wherein the first preformed tubing loop has a greater wall thickness than the second preformed tubing loop such that the first preformed tubing loop can withstand higher pressures than the second preformed tubing loop;
wherein the housing further includes a second side, a third side, and a fourth side; and
wherein the second side, the third side, and the fourth side of the housing are free of tubing loops; and
an aspiration tube extending from the housing;
an infusion tube extending from the housing; and
a catheter controller coupled to the aspiration tube and coupled to the infusion tube, the catheter controller being spaced apart from the housing.
