Abstract
A fluidics management system includes a cassette configured to receive saline from a saline source, receive contrast from a contrast source, and receive vacuum from a vacuum source. The cassette includes a plurality of saline connectors, each of the plurality of saline connectors configured to couple to one of a plurality of catheters to provide saline thereto, a plurality of contrast connectors, each of the plurality of contrast connectors configured to couple to one of the plurality of catheters to provide contrast thereto, and a plurality of vacuum connectors, each of the plurality of vacuum connectors configured to couple to one of the plurality of catheters to provide vacuum thereto.
Core Innovation
The invention provides a fluidics management system that uses a cassette configured to receive saline from a saline source, receive contrast from a contrast source, and receive vacuum from a vacuum source. The cassette includes a saline flow path, a contrast flow path, and a vacuum flow path, each being configured for fluid communication with at least one of a plurality of catheters to provide the respective fluid.
The system further includes one or more robotically actuated vacuum valves positioned along the vacuum flow path and controlled by a control system. The system includes a plurality of hubs in which at least one hub is in fluid communication with the saline flow path, the contrast flow path, and the vacuum flow path, and at least one of the hubs comprises a hemostasis valve in fluid communication with the saline flow path, the contrast flow path, and the vacuum flow path.
The cassette architecture further includes a plurality of contrast connectors, each configured to couple to one of the plurality of catheters to provide contrast thereto. The cassette further comprises a plurality of contrast valves, each configured to selectively place one of the plurality of contrast connectors in fluid communication with the contrast source.
Claims Coverage
The document includes three independent claims (clm-00001, clm-00015, and clm-00017). Across these claims, the inventive features focus on a disposable cassette providing separate saline, contrast, and vacuum flow paths to multiple catheters, robotically actuated vacuum valves controlled by a control system, hub-based fluid communication with an integrated hemostasis valve, and selective placement of contrast connectors into fluid communication with a contrast source using contrast valves.
Cassette with saline, contrast, and vacuum flow paths to multiple catheters
A cassette configured to receive saline from a saline source, receive contrast from a contrast source, and receive vacuum from a vacuum source, comprising a saline flow path, a contrast flow path, and a vacuum flow path, each configured to be in fluid communication with at least one of a plurality of catheters to provide the respective saline, contrast, and vacuum thereto.
Robotically actuated vacuum valves along the vacuum flow path under control of a control system
One or more robotically actuated vacuum valves positioned along the vacuum flow path and configured to be controlled by a control system.
Hubs with hemostasis valve communicating with saline, contrast, and vacuum flow paths
A plurality of hubs, at least one of the plurality of hubs being in fluid communication with the saline flow path, the contrast flow path, and the vacuum flow path, wherein the at least one of the plurality of hubs comprises a hemostasis valve in fluid communication with the at least one of the saline flow path, the contrast flow path, and the vacuum flow path.
Contrast connectors and contrast valves selectively placing contrast connectors in communication with the contrast source
A cassette comprising a plurality of contrast connectors, each configured to couple to one of the plurality of catheters to provide contrast thereto, and a plurality of contrast valves, each configured to selectively place one of the plurality of contrast connectors in fluid communication with the contrast source.
Across the independent claims, the coverage centers on a multi-flow-path cassette that provides saline, contrast, and vacuum to multiple catheters, robotically actuated vacuum valves controlled by a control system, hub-based distribution including a hemostasis valve communicating with saline, contrast, and vacuum flow paths, and selective contrast distribution using contrast connectors and contrast valves.
