A blood oxygenator includes a housing having a first end opposite a second end with a sidewall extending between the first end and the second end along a longitudinal axis. The housing defines an interior chamber having a liquid inlet at the first end and a liquid outlet at the second end. The oxygenator further includes a gas exchange assembly positioned within the interior chamber. The gas exchange assembly includes a retainer having an upper cap spaced apart from a lower cap by one or more spacers, and a gas exchange medium disposed between the upper cap and the lower cap. The gas exchange medium has a plurality of subunits stacked on top of each other, with each subunit having a plurality of layers of hollow fiber mats.

Oxygenator with stacked fiber membrane

A connector has a hollow body having a first open end spaced apart from a second open end with a lumen extending between the first and second open ends. At least one channel extends through a sidewall of the body and is recessed from a terminal surface of the first open end. The first open end is sized to be received within an open end of a first tubing. When the first open end is partially inserted into the open end of the first tubing, the at least one channel and a terminal surface of the open end of the first tubing define an opening positioned so that fluid passes through the opening into or out of the lumen. When the first open end is fully inserted into the first tube, the at least one channel is covered by an inner surface of the first tubing to cover the opening.

Sterile connector and cannula assembly

A cannula includes a tube having a proximal end, a distal end, and a tubular sidewall extending between the proximal end and the distal end. The cannula further includes an extendable member provided on a portion of the sidewall. The extendable member is configured to extend radially outward from the sidewall. The sidewall defines an aperture located between the proximal end and the distal end of the main tube.
