Abstract
A cannula assembly including a housing, a rotatable member, a first plurality of membranes, and a second plurality of membranes is disclosed. The housing may include a distal end defining a distal opening, wherein the distal end is configured to couple to a cannula tube aligned with the distal opening, and a proximal end defining a proximal opening. The rotatable member may be positioned within the housing and may define a passage in fluid communication with the distal opening, a first opening in fluid communication with the passage, and a second opening in fluid communication with the passage. The first plurality of membranes may be arranged as a stack at the first opening, wherein each of the first plurality of membranes defines an aperture. The second plurality of membranes may be arranged as a stack at the second opening, wherein each of the second plurality of membranes defines an aperture. The rotatable member may be configured to rotate within the housing between a first position and a second position, wherein in the first position, the first opening aligns with the distal opening of the housing, and wherein in the second position, the second opening aligns with the distal opening of the housing.
