Abstract: Described is a blood processing apparatus with a blood flow path and a heat exchanger fluid flow path overlapping the a heat exchanger chamber, in which the blood flows generally from a first end to a second end of the blood processing apparatus, and the heat exchanger fluid flows generally from the second end to the first end. Such “counter” or “countercurrent” flow improves heat transfer between the blood and the heat exchanger fluid. The blood processing apparatus includes a housing, a blood inlet, a heat exchanger fluid inlet and a heat exchanger fluid outlet, a heat exchanger core, a cylindrical shell having an annular shell aperture, a blood flow distributor, and a central chamber in fluid communication to a fluid flow distributor.

Abstract: A blood reservoir may be used in combination with other elements such as a heart lung machine (HLM), oxygenator, heat exchanger, arterial filter and the like to form an extracorporeal blood circuit that may be employed in a procedure such as a bypass procedure. The blood reservoir may be configured to receive, filter and store blood from a number of sources including vent blood (from within the heart), venous blood (from a major vein), purge blood (from a sampling line) and cardiotomy or suction blood (from the surgical field).

Abstract: A system includes a cuvette including a cuvette body forming a substantially planar exterior surface and having a sensor window defined within the substantially planar exterior surface. The cuvette further includes a probe retention structure extending from the cuvette body. The system includes a probe with a probe body and a protrusion that is removably coupled to the probe retention structure.

Abstract: A vacuum assisted venous blood reservoir has a controller that can sense pressure within a sealed blood chamber. The controller regulates the amount of vacuum within the chamber to control the level of blood in the venous reservoir. A safety valve is included to prevent blood from entering the vacuum line.

Abstract: A device for treating blood in an extracorporeal circuit comprising a venous blood reservoir having an inlet and an outlet, and a hemoconcentrator having a first inlet connector for the blood to be treated, a second outlet connector for the outflow of concentrated blood, and a third outlet connector for the outflow of the ultrafiltered liquid, wherein the hemoconcentrator is disposed within the venous blood reservoir and the hemoconcentrator and the venous blood reservoir are integrated into a single monolithic assembly, and wherein the hemoconcentrator comprises an enclosure containing structure suitable to concentrate blood.
