  • Patent number: 11419973
    Abstract: A lavage unit may include a handpiece configured to house a pump to which an irrigation tube is connected. The pump may include a bellows defining a pump chamber. When the bellows is reciprocated by a linkage, the bellows draws irrigation fluid from the irrigation tube into the pump chamber and then discharges the fluid out of the pump chamber through an outlet. The pump further includes a section formed from compressible or flexible material that defines a supplemental chamber. The linkage is connected to said pump to alternatively compress the bellows forming the pump chamber and the material forming the supplemental chamber. During the movement of the linkage a valve located between the pump chamber and the supplemental chamber reciprocates with the linkage.

  • Patent number: 11247037
    Abstract: A controller is provided to determine a ventricular filling phase slope as an indicator of high pulmonary capillary wedge pressure and/or cardiac index. Flow rate values describing a blood flow rate through a ventricular assist device are received. A ventricular filling phase segment is identified from a portion of the received flow rate values. A slope of the received flow rate values during the identified ventricular filling phase segment is determined. The determined slope is compared to a predetermined threshold value. When the determined slope exceeds the predetermined threshold value based on the comparison, a warning is triggered regarding an elevated pulmonary capillary wedge pressure or a low cardiac index value.
