The invention provides a fluid management system (1) for providing fluid from a fluid source (20) to the body of a patient. The fluid management system (1) includes a compressible chamber (10). A fluid conduit (30) is in fluid communication with the fluid source (20) and with an interior of the compressible chamber (10). A bypass conduit (40) has an inlet end (43) in fluid communication with the fluid source (20) and an outlet end (44) for providing fluid to a trocar (70). The bypass conduit 40 passes either through or around the compressible chamber (10). A first one way valve (80) can admit fluid from the fluid conduit (30) into the interior of the compressible chamber (10). A second one way valve (90) can admit fluid within the interior of the compressible chamber (10) into the bypass conduit (40). A portion (46) of the bypass conduit (40) upstream of the second one way valve (90) is collapsible under the force of selectively applied external pressure when the compressible chamber (10) is at least partially filled with fluid from the fluid source (20), so as to selectively close off the bypass conduit (40) upstream of the second one way valve (90).

A syringe having two variable volumes are described herein. The syringe includes a first stopper and a second stopper, the first stopper being connected to a plunger. A first variable volume is disposed between the first stopper and the second stopper and a second variable volume is between the second stopper and a distal end of a barrel of the syringe. A flow path structure is disposed at the distal end of the barrel, the flow path structure extending from the distal end of the barrel along the inner sidewall of the barrel.

The present disclosure describes devices, systems, and methods for intravascularly delivering an implantable device to a targeted anatomical site such as the mitral annulus. A delivery system includes a delivery member coupled to a handle assembly and extending distally from the handle assembly. A delivery catheter is concentrically positioned within an outer member and configured to advance the intravascular device relative to the outer member. The delivery catheter includes a distal can structure configured to house at least a portion of the intravascular device in a compressed, pre-deployed position.

An infusion pump system and method provide concurrent infusion with common line auto flush. The infusion pump system has a first reservoir, a second reservoir, a junction, a mixing chamber, a common line having one end in fluid connection with the mixing chamber and having a terminal fluid delivery end, and an infusion pump. The method includes infusing the first fluid at a first rate along a first flow path; determining a common line flush volume value for the common line; switching to a concurrent infusion mode to drive a combination of the first fluid and the second fluid at the first rate along a second flow path including the common line; monitoring a volume of the combination of the first and second fluids driven at the first rate; and driving the combination of the first and second fluids at a combined rate along the second flow path when the monitored volume is equal to or greater than the common line flush volume value.

Infusion system configurations and assemblies facilitate routing of infusion circuit tubing lines. Tubing lines are routed into and out from compartments of a shielding assembly for the infusion system, at locations which prevent kinking and/or crushing of the lines, and/or provide for ease in assembling the circuit. A plurality of the lines may be held together by a support frame to form a disposable infusion circuit subassembly, that can further facilitate routing of the lines.

This purge device comprises a connection element comprising a plurality of fluid flow channels which each comprise a proximal end, intended to be connected fluidically to a respective fluid flow conduit of a flow tube, and a distal end opposite the respective proximal end, and a plurality of fluid flow openings which are each connected fluidically to a respective fluid flow channel; a closure element comprising a fluid evacuation opening and a closure part, the closure element being mounted movably with respect to the connection element and being configured to occupy a plurality of closure positions, in each of which the closure part closes the distal end of a fluid flow channel and the fluid evacuation opening is connected fluidically to the fluid flow opening associated with the fluid flow channel, of which the distal end is closed by the closure part; and a connection nozzle intended to be connected to a catheter.

A syringe assembly includes (i) a syringe with a cylindrical body, luer tip at a first end, finger grip at a second end and a cannula extending from the luer tip into the cylindrical body, and (ii) a plunger unit having an adapter portion, receiving cavity, finger grip and piston. A channel extends the length of the adapter portion to receive the cannula in one end and a variety of connectors, valves and/or syringes in a second end. The end of the channel accessible in the receiving cavity mates with or engages any number of commercially available valves, connectors and/or syringes while the luer tip similarly connects to any number of valves, catheters, connectors, etc., depending on the task being undertaken with the syringe assembly.

A system for injecting fluid to a patient is provided. The system provides manual or automatic verification and identification of the fluid to be injected, prior to, during or after injection. The system includes: a fluid having at least one active compound and at least one tracer compound; an injector configured to deliver the fluid to the patient through a fluid path set; at least one sensor coupled to at least one of the syringe, the injector, or the patient, configured to measure at least one property of the tracer in the fluid, and a feedback path to adjust at least one injection parameter of the injector based on at least one measurement from the at least one sensor.
