Abstract: A stent for reducing the passage of emboli into body lumen once deployed includes a structural portion and a barrier portion. The structural portion, when expanded in a conduit, provides sufficient strength to maintain an open lumen in the conduit. The barrier portion reduces migration of emboli from the wall of the conduit through the structural portion and into the lumen. Stent delivery systems capable of delivering and deploying the stent are disclosed.

Abstract: Blood processing systems and methods convey blood cells from a blood cell source into a blood component collection flow channel that includes a blood cell storage container and an in-line filter to remove leukocytes from blood cells before entering the blood cell storage container. The systems and methods also convey additive solution from an additive solution source into the blood component collection flow channel. The systems and methods alternate the conveyance of blood cells through the filter with the conveyance of additive solution through the filter.

Abstract: A blood processing system comprises a processing chamber to process blood and a fluid flow cassette that communicates with the processing chamber. The cassette comprises a body, a pump chamber formed in the body, and a flexible diaphragm on the pump chamber responsive to an applied fluid pressures for flexure toward and away from the pump chamber to pump fluid through the pump chamber. The cassette also includes a flow path formed, at least in part, in the body to couple the pump chamber in fluid flow communication with the processing chamber, to convey fluid pumped by the pump chamber into the processing chamber. The cassette also includes an in line cavity formed in the body and located in the flow path to trap air to prevent entry of air into the processing chamber.

Abstract: Blood processing systems and related methods place first and second fluid pressure actuated pump stations in in-line communication between a source and a destination. The systems and methods apply fluid pressure pump strokes to the first and second pump stations to convey fluid from the source to the destination. The systems and methods switch between a first flow mode and a second flow mode. In the first flow mode, the pump strokes draw a fluid volume into the first pump station from the source and expel a fluid volume from the second pump station to the destination. In the second flow mode, the pump strokes draw a fluid volume into the second pump station from the source and expel a fluid volume from the first pump station to the destination. The systems and methods synchronize the pump strokes so that fluid flow from the source is essentially continuous while fluid flow to the destination is pulsatile.

Abstract: A multiple function pump station performs different on-line processing tasks. The pump station can be operated in one mode to draw blood from a donor and, in another mode, be operated to return blood to the donor. The pump station used to draw blood from a donor can also be used to perform subsequent blood processing tasks, such as mixing or processing additive fluids with the blood, or transfering a harvested blood component to a storage container, or finishing the processing of a harvested blood component.

Abstract: Systems and methods separate blood cells from whole blood and pump the separated blood cells through an in-line leukofilter to a blood cell storage container. The leukofilter has a filtration medium enclosed within a flexile housing. The systems and methods employ a fixture to restrain expansion of the flexible filter housing during operation of the pump. The fixture has a bracket to enable its releasable attachment to the blood processing device employed to carry out the separation process.
