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. A medical system, comprising:
a control console including a housing;
a first peristaltic pump coupled to the housing;
a second peristaltic pump coupled to the housing;
a tubing cassette coupled to the housing;
wherein the first peristaltic pump includes an infusion pathway designed to engage a first infusion tube of the tubing cassette;
wherein the second peristaltic pump includes an aspiration pathway designed to engage a second aspiration tube of the tubing cassette;
wherein the first infusion tube is different from the second aspiration tube;
wherein the first infusion tube has a first wall thickness, and wherein the second aspiration tube has a second wall thickness different from the first wall thickness.

2. The medical system of claim 1 , wherein the first peristaltic pump generates a first pressure within the first infusion tube, and wherein the second peristaltic pump generates a second pressure within the second aspiration tube, and wherein the first pressure is greater than the second pressure.

3. The medical system of claim 2 , wherein the first peristaltic pump includes a first set of rollers designed to advance an infusion fluid through the first infusion tube at the first pressure.

4. The medical system of claim 3 , wherein the second peristaltic pump includes a second set of rollers designed to advance an aspiration fluid through the second aspiration tube at the second pressure.

5. The medical system of claim 4 , wherein the first pressure is less than or equal to 160 psi.

6. The medical system of claim 5 , wherein the second pressure is less than or equal to 20 psi.

7. The medical system of claim 1 , wherein the first infusion tube has a first stiffness, and wherein the second aspiration tube has a second stiffness different from the first stiffness.

8. The medical system of claim 1 , wherein the first peristaltic pump, the second peristaltic pump or both the first peristaltic pump and the second peristaltic pump are positioned within the housing.

9. The medical system of claim 1 , further comprising a control panel coupled to the housing.

10. The medical system of claim 1 , wherein each of the first infusion tube and the second aspiration tube forms a U-shaped loop, and wherein each the first infusion tube and the second aspiration tube extends away from the tubing cassette in the same direction in a side-by-side arrangement.

11. A medical device system, comprising:
a control console including an infusion system and an aspiration system;
a tubing cassette including a first infusion tube and a second aspiration tube, wherein the first infusion tube is different from the second aspiration tube;
wherein the infusion system includes an infusion pump defining an infusion pathway designed to mate with the first infusion tube;
wherein the aspiration system includes an aspiration pump defining an aspiration pathway designed to mate with the second aspiration tube;
wherein the infusion pump is designed to infuse fluid at a first pressure and wherein the aspiration pump is designed to aspirate fluid at a second pressure different from the first pressure;
wherein the first infusion tube has a first stiffness, and wherein the second aspiration tube has a second stiffness different from the first stiffness.

12. The medical device system of claim 11 , wherein the infusion pump includes a first set of rollers designed to infuse fluid through the first infusion tube at the first pressure, and wherein the aspiration pump includes a second set of rollers designed to advance an aspiration fluid through the second aspiration tube at the second pressure.

13. The medical device system of claim 11 , wherein the first pressure is less than or equal to 160 psi.

14. The medical device system of claim 13 , wherein the second pressure is less than or equal to 20 psi.

15. The medical device system of claim 11 , wherein the first infusion tube has a first wall thickness, and wherein the second aspiration tube has a second wall thickness different from the first wall thickness.

16. The medical device system of claim 11 , wherein the infusion pump, the aspiration pump or both the infusion pump and the aspiration pump are positioned within the control console.

17. The medical device system of claim 11 , further comprising a control panel coupled to the control console.

18. A medical device system, comprising:
a control console including a control panel, an infusion system and an aspiration system; and
a tubing cassette including a high pressure tube and a low pressure tube extending away therefrom, wherein the high pressure tube is different from the low pressure tube;
wherein the control panel is configured to communicate with the infusion system and the aspiration system;
wherein the infusion system includes a high pressure tubing pathway including a first set of high pressure rollers;
wherein the aspiration system includes a low pressure tubing pathway including a second set of low pressure rollers;
wherein the first infusion tube has a first wall thickness and a first stiffness, and wherein the second aspiration tube has a second wall thickness and a second stiffness, and wherein the second wall thickness is different from the first wall thickness, the second stiffness is different from the first stiffness or both the second wall thickness is different from the first wall thickness and the second stiffness is different from the first stiffness.
