Abstract: Certain embodiments disclosed herein provide a surgical cassette including a housing, one or more retaining rings coupled to the housing, and one or more valve assemblies coupled to the housing by the one or more retaining rings. The one or more valve assemblies configured to control fluid communication between one or more channels within the housing. Each valve assembly includes a valve body having a first end with a first shoulder, a second end with a second shoulder, a cylindrical surface connecting the first shoulder and second shoulder, and an upper valve elastomer. The upper valve elastomer includes a first side configured to engage with the first shoulder of the valve body and a second side configured to engage with the retaining ring to facilitate a fluidic seal at a base of the housing.

The one or more valve assemblies configured to control fluid communication between one or more channels within the housing. Each valve assembly includes a valve body having a first end, a second end, a cylindrical surface connecting the first end and second end, and a valve elastomer. The valve elastomer includes a first side configured to couple the valve elastomer to the second end of the valve body and a second side having a recessed surface configured to engage with the housing to form a seal with a base of the housing and reduce mechanical stress across the valve elastomer during rotation of the valve assembly.
