Medical devices and related systems and methods

A medical device comprising:

• a handle comprising a first conduit and a second conduit each coupled to a valve assembly within a housing of the handle, the valve assembly comprising:
• an outer body including a first fluidics channel adjacent to a third fluidics channel on a first side of the outer body;
• and a second fluidics channel adjacent to a fourth fluidics channel on a second side of the outer body opposite the first side;
• and
• an inner body slidable or rotatable within the outer body, an end of the inner body being coupled to the housing and configured to receive user input;
• wherein the valve assembly includes a first configuration in which the first fluidics channel and the second fluidics channel are in fluid communication with each other and with the first conduit, and the third fluidics channel and the fourth fluidics channel are in fluid communication with each other and with the second conduit;
• wherein the valve assembly includes a second configuration in which the first fluidics channel and the third fluidics channel are in fluid communication with each other and with the first conduit, and the second fluidics channel and the fourth fluidics channel are in fluid communication with each other and with the second conduit;
• and
• wherein moving the inner body relative to the outer body by user input transitions the valve assembly between the first configuration and the second configuration.

A medical device comprising:

• a handle comprising a first conduit and a second conduit each coupled to a valve assembly within a housing of the handle, the housing including a fluid inlet and an aspiration outlet, wherein the valve assembly comprises:
• an outer body including a first fluidics channel and a third fluidics channel on a first side of the outer body;
• and a second fluidics channel and a fourth fluidics channel on a second side of the outer body opposite the first side;
• and
• an inner body movable within the outer body;
• wherein the valve assembly includes a first configuration in which the first fluidics channel and the second fluidics channel are in fluid communication with each other and with the first conduit, and the third fluidics channel and the fourth fluidics channel are in fluid communication with each other and with the second conduit;
• wherein the valve assembly includes a second configuration in which the first fluidics channel and the third fluidics channel are in fluid communication with each other and with the first conduit, and the second fluidics channel and the fourth fluidics channel are in fluid communication with each other and with the second conduit;
• wherein moving the inner body relative to the outer body by user input transitions the valve assembly between the first configuration and the second configuration;
• and
• wherein the fluid inlet being is connected to the first fluidics channel and the aspiration outlet is connected to the fourth fluidics channel in both the first configuration and the second configuration.
