Abstract: An oxygenator includes a housing having a blood inlet and a blood outlet, the blood inlet extending into an interior of the housing. A heat exchanger is disposed within the housing, and is coupled, at an inlet end, to a heat-exchange fluid inlet. A gas exchanger also is disposed within the housing, and includes a bundle of gas-exchange fibers coupled, at a gas outlet end, to a gas-exchange fluid outlet. The oxygenator includes at least one insulator configured to thermally insulate at least the gas outlet end of the bundle of gas-exchange fibers.

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 for removing gaseous micro emboli from blood prior to oxygenation. The system including a module having a blood inlet, a blood outlet, and a port configured to provide atmospheric or sub-atmospheric pressures, and microporous hollow fibers situated in the module and fluidly coupled to the port to provide the atmospheric or sub-atmospheric pressures inside the microporous hollow fibers. The module is configured to receive the blood through the blood inlet such that the blood flows from the blood inlet to the blood outlet around outside surfaces of the microporous hollow fibers such that at least some of the gaseous micro emboli in the blood are drawn from the blood through the microporous hollow fibers by the atmospheric or sub-atmospheric pressures.

Abstract: A purger device for hollow fiber oxygenators, including a gas inlet, a gas outlet, and a fluid communication feature between the gas inlet and the gas outlet. The purger device further including an accumulation chamber having a variable volume plenum ported to the fluid communication feature, and a flow control unit configured to vary fluid communication patterns in the fluid communication feature and having a first operating condition and a second operating condition, wherein in the first operating condition the flow control unit enables a fluid communication between the gas inlet and gas outlet, and wherein in the second operating condition the flow control unit enables a fluid communication between the gas inlet and the variable volume plenum of the accumulation chamber.

Abstract: A venous reservoir including a single inlet line clamp capable of partially or completely restricting blood flow to the venous reservoir. The venous reservoir is provided with a rigid back plate or bracket that can accommodate an inlet line capable of joining to at least one blood inlet port. The rigid back plate or bracket can accommodate a clamp capable of completely or partially closing the inlet line containing both the cardiotomy line and the venous line to manually control the blood flow drained from the patient.

Abstract: An oxygenator combines, in a single structure, a heat exchanger, a gas exchanger, an arterial filter, and a filter frame. Such an oxygenator permits fewer fluid connections and thus may simplify an extracorporeal blood circuit, including a heart-lung machine and a blood reservoir, in which it is used. In some embodiments, the oxygenator may be configured to include multiple purge ports for purging bubbles both before and after filtering the blood.
