  • Patent number: 12226623
    Abstract: A centrifugal blood pump includes a housing having a pumping chamber, an inlet having an inlet axis, and an outlet having an outlet axis. The inlet and the outlet are in fluid communication with the pumping chamber. The pump further includes an impeller rotatably disposed within the pumping chamber, and a strut connected to the housing at the inlet. The strut is connected to the housing at a circumferential position about the inlet axis such that a major axis of the strut and the outlet axis define a predetermined angle in a cross-sectional plane perpendicular to the inlet axis. The circumferential position of the strut relative the outlet axis reduces or eliminates damage to blood flowing around the strut.

  • Publication number: 20240350790
    Abstract: An adaptor for use in a blood conduit of an extracorporeal life support system. The adaptor includes a body defining a main passageway and an auxiliary port extending from the body with a passageway of the auxiliary port converging with the main passageway. The auxiliary port includes a hemostasis valve configured to selectively seal around a medical device inserted through the auxiliary port into the main passageway. An elastomeric valve may be positioned in the passageway of the auxiliary port spaced away from the hemostasis valve such that elastomeric valve is located between the hemostasis valve and the main passageway. In some instances, the hemostasis valve may be removably couplable to the auxiliary port.

  • Patent number: 11937773
    Abstract: An endoscope including: a handle, a distal tip unit, an endoscope shaft connecting the handle and the distal tip unit, a working channel provided in the endoscope shaft, and a suction valve configured to control a suction through the working channel and having a valve closed state and a valve open state. The suction valve includes a housing having an inlet opening connected to the working channel and an outlet opening; and a piston unit inserted in the housing. The piston unit comprises a movable piston, a button attached to the piston, a fixation ring arranged stationary in the housing and a spring arranged and acting between the fixation ring and the button or piston. The button is a one-piece or integral part having an integrated sealing portion contacting the housing and providing a sealing between the button and the housing in the valve open state.
