Embodiments of water sensors having multi-value outputs are disclosed. A water sensing circuit measures the impedance between two contacts of a water sensor and compares it with a reference signal. The impedance between two contacts varies depending on the wetness of the contacts, and so the sensing circuit may provide a measured wetness level. The water sensor may transmit measurements or other information wired or wirelessly. The water sensor may display indicia of measurements or other information via a display on a housing.

Water sensors with multi-value outputs and associated systems and methods

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.

Interventional catheter assemblies, control consoles and adaptive tubing cassettes

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.

Adaptive tubing cassettes for use in connection with interventional catheter assemblies

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. Control instructions for operating the interventional catheter assembly and authentication protocols for verifying system matches and operating conditions maybe encoded in hardware, firmware or software, such as a memory or storage device, provided in the interventional catheter assembly or in a discrete adaptive interface component. Adaptive components such as tubing cassettes routing aspiration and/or infusion tubing in a predetermined configuration to mate with aspiration and infusion systems on a control console are also provided.
