Adaptive tubing cassettes for use in connection with interventional catheter assemblies
First Claim
1. An adaptive tubing cassette for use in connection with an interventional catheter assembly, comprising:
- a handle component having an interface region adapted to mount stably in a mating interface region of a control console;
a first preformed tubing section and a second preformed tubing section, each of the preformed tubing sections being in the form of a loop, mounted to and extending from a common side of the handle component, the first and second preformed tubing sections being adapted to mount stably in tubing receiving pathways provided in connection with the control console;
wherein the first preformed tubing section is configured to withstand a higher burst pressure than the second preformed tubing section.

Abstract
Peristaltic pump assemblies in which the closing and opening of a pivoting or sliding door is coordinated with movement of the occlusion bed toward and away from the rotor assembly to engage and disengage tubing within the occlusion pathway are disclosed. Linkage mechanisms provided by the interaction of cam surfaces with rollers, as well as bar linkage mechanisms, are disclosed. The linkage mechanism, in addition to providing precise displacement of the occlusion bed, may also provide an over-center feature that enhances safety and pump operation when the door is in a closed position. Latching mechanisms and sensors may be incorporated. Control consoles incorporating such peristaltic pump assemblies are described. Adaptive components such as tubing cassettes routing aspiration and/or infusion tubing in a predetermined configuration to mate with occlusion pathways in aspiration and/or infusion pump assemblies provided in various types of medical devices and control consoles are also provided.

20. A peristaltic pump system, comprising:
-
a control console having an infusion system and an aspiration system; an adaptive tubing cassette including a handle member, an infusion tube, and an aspiration tube, wherein the infusion tube and the aspiration tube extend from the handle member; wherein the adaptive tubing cassette is designed to engage a receiving region of the infusion system and a receiving region of the aspiration system; wherein the receiving region of the infusion system is designed to accept the infusion tube, and wherein the infusion tube has a first burst strength; and wherein the receiving region of the aspiration system is designed to accept the aspiration tube, and wherein the aspiration tube has a second burst strength different from the first burst strength.
