    Abstract: A circumferential flow path (86) is established about an axis of rotation, while the circumferential flow path (86) is rotated about the axis. Blood is introduced into the rotating circumferential flow path (86) through an inlet port (122) having an axis that is parallel to the axis of rotation. The axial inlet flow together with the circumferential separation flow creates a vortex region (148) that circulates about the port axis and stretches across the circumferential flow path (86). The vortex region (148) perfuses the blood uniformly into the circumferential flow path (86) for separation into constituent parts.

    Abstract: A blood oxygenator/heat exchanger system (10) includes disposable and durable components, the latter being possible of permanent installation to further reduce costs, inconvenience and risks of use. The system may selectively include a blood pump (136) of axial, centrifugal, or ventricular type, along with an integral venous reservoir (206). By combination, arrangement and cooperation of structural features blood pumping volume is decreased, advantageous blood flow paths are achieved, blood damage is reduced, and durable components are reusable for lowest costs. The oxygenator/heat exchanger (58) nests upon a durable heat source base (24) to be supported thereby, while redundant boundaries are provided between blood and heat transfer media.

    Abstract: A low priming volume centrifugal pump comprising a disc shaped impeller (10) having opposite faces (16, 18) and an inlet hole (20) centrally disposed therein. The impeller (10) has flow channels (12, 14) disposed on at least one of the faces (16, 18) of the impeller (10) which radiate outward from said inlet hole (20). The volume of the flow channels (12, 14) is small relative to the total impeller envelope volume providing for efficient momentum transfer with a minimum of turbulence and backflow. Thus, priming volume is reduced and flow within the pump is more efficient. The pump can be used as stand alone device, or it can be integrated with a blood oxygenator into a common housing.

    Abstract: A method, device and system, for providing a flow of oxygenated perfusion fluid (e.g. oxygenated whole blood) through a balloon angioplasty catheter (100) to perfuse tissues which would normally be deprived of blood flow when the balloon (132) of the angioplasty catheter (100) is inflated. In accordance with the invention, an extracorporeal membrane oxygenation device (12) is fluidly connected to the angioplasty catheter (100) such that oxygenated fluid (e.g. oxygenated whole blood) may be passed through the catheter (100) and caused to exit the catheter (100) distal to the angioplasty balloon (132). The patient's own blood may be withdrawn, oxygenated by the extracorporeal membrane oxygenation device (12) and subsequently reinfused through the angioplasty catheter (100). A dual-lumen introducer sheath (102) may be employed for the dual function of a) facilitating insertion of the catheter (100) and b) allowing withdrawal of blood for subsequent oxygenation and reinfusion through the angioplasty catheter (100).

    Abstract: A frangible seal (40) for a fluid path including a frangible seal member secured within a tube defining the fluid path. The frangible seal member having a tubular seal member (42) and a stem (43)extending from the tubular seal member which, upon bending back and forth, breaks away from the seal member thereby to rupture the tubular seal in the fluid path. The tubular seal member and stem are integrally formed of a non-PVC material. The tubular seal member will bond to PVC tubing during steam heating thereof. The tubular seal member and stem are constructed to provide uniform non-reclosable rupturing. The stem includes vanes with spurs that frictionally engage the inner walls of the tube to maintain separation of the stem and ruptured tubular seal member.
