    摘要： A heat exchanger is provided which may be used in an integrated blood oxygenator and heat exchanger. The heat exchanger has a plurality of wave shaped sinusoidal channels on one or both sides. The heat exchanger has a cap attached at the upper end. The heat exchanger is disposed within a housing. The bottom end of the heat exchanger is bonded to the bottom end of the housing, and the upper end of the heat exchanger with the cap attached is spaced apart from the upper end of the housing. A liquid inlet and outlet are in fluid communication with the inner surface of the heat exchanger. A blood inlet and outlet are in fluid communication with the outer surface of the heat exchanger. The heat exchanger may be used with a blood oxygenating chamber. The blood oxygenating chamber contains a plurality of permeable hollow fibers which oxygenate blood flowing through the blood oxygenating chamber. The blood oxygenating chamber is in fluid communication with the outer surface of the heat exchanger and the blood outlet.

    摘要： An arterial filter includes a filter housing provided with a uniquely shaped housing cover. The housing cover is in the shape of a toroid which forms a coil-like tunnel which is enlarged midway about the circumference of the housing cover. The highest point of the toroidal channel is at the periphery of the housing cover, approximately 180.degree. from the inlet valve. A gas vent is located at this highest point on the top of the toroid-shaped housing cover. At the center of the housing cover is an indentation which is provided to both retain a cylindrical filter element inside the filter housing, as well as allow visibility directly through the central axis of the arterial filter to verify proper operation of the filtration process. As inlet blood circulates through the toroidal tube forming the filter housing cover, gaseous matter is allowed to buoyantly escape out of the gas vent located at the top of the raised section of the toroidal channel. The remaining debubbled fluid seeps down into a reservoir formed between the cylindrical filter housing and the outer perimeter of the filter element contained therein. The filter element draws the fluid toward the center of the filter housing, as it simultaneously filters out undesired particulate and gaseous matter. The filtered product then passes into the hollow central area of the filter element and exits through an outlet vent located at the bottom of the filter housing.

    摘要： A holder for a heat exchanger in a cardioplegia delivery system including dual couplers releasably engageable with the inlet and outlet ends of the heat exchanger. A one-way shut-off valve is associated with each coupler and opened to provide communication upon mounting of the heat exchanger. The valves automatically close upon release of the heat exchanger. A release member engages both couplers and is manually retractable to simultaneously open both couplers for release of both heat exchanger fittings for instantaneous release of the heat exchanger and a closing of the associated valves.

    摘要： A fluid treatment arrangement may include a fluid treatment unit having a multilayer structure. The multilayer structure may include at least one feed layer, at least one permeate layer, and at least one layer of a permeable fluid treatment medium between the feed layer and the permeate layer. The fluid treatment unit may further include a thermoset which holds the layers together and forms at least a portion of a first end surface of the fluid treatment unit. The fluid treatment arrangement may also include a thermoplastic sheet which overlies the first end surface of the fluid treatment unit. The thermoset directly bonds to the thermoplastic sheet.

    摘要： An anastomosis device is provided for making connections between various conduits in the body of a patient. The device includes a first assembly that is threaded through the target conduit of the patient to a desired location. The device then pierces the wall of the target conduit and is then attached to an external assembly that is withdrawn through the wall of the target conduit to draw the desired connector and a graft conduit into the desired position along the wall of the target conduit. Thereafter, the first assembly is separated from the connector and graft conduit. In this invention, the connector may be a stent like device, staples or similar components to secure the graft conduit to the desired location along the wall of the target conduit.
