Various embodiments of a system for priming a catheter assembly are disclosed herein. For example, the system can include a catheter assembly including an elongate body and an operative device coupled thereto. The system can also include a priming vessel configured to receive insertion of the operative device therein. The priming vessel can include a proximal portion secured to the distal portion of the elongate body such that the elongate body is in fluid communication with the priming vessel. The priming vessel can also include a distal end through which air is expelled when a fluid is channeled through the elongate body and into the priming vessel to expel air from within the catheter assembly.

Fluid handling system

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.

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.

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.

A syringe for performing a medical procedure includes a pressure sensor, a volume sensor, and a compensation circuit. The volume sensor measures a volume of a flowable material that is dispensed from the syringe, the pressure sensor measures a pressure being applied to the flowable material, and the compensation circuit calculates a delivered volume of the flowable material by accounting for system compliance (expansion) as the pressure is increased. By compensating for system compliance in this manner, a syringe can be used in high pressure procedures while still providing accurately controllable material delivery.

A connector for use with a lumen device during the cleaning and sterilization of devices is provided. The connector provides fluid communication between a fluid source and the device. In particular, during the cleaning and sterilization cycle, the connection between the connector and the device does not produce occluded areas at the point of connection where the connector is sealably attached to the device.
