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, 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.

Abstract: Embodiments disclosed herein provide a surgical cassette including a housing having a base and a cover coupled to the base, wherein the cover and the base each at least partially define one or more channels. The housing further includes a plurality of ports formed in the base and in fluid communication with at least one of the one or more channels, a plurality of bores formed in the base and configured to receive one of a plurality of valve assemblies, and at least one pump landing formed in the base and configured to receive at least one pump assembly. A plurality of valve assemblies is disposed within the plurality of bores and configured to control fluid flow in the one or more channels of the housing. At least one pump assembly is disposed within the at least one pump landing and configured to provide a source of pressure or vacuum to the one or more channels of the housing.

Abstract: Embodiments disclosed herein provide a surgical cassette including pump assemblies with improved contact between a displacement sensor disposed within a surgical console and a diaphragm disposed within the surgical cassette. Each pump assembly includes a diaphragm retainer ring that provides a sufficient creepage and clearance margin, acts as a lead-in for the displacement sensor, assists in preventing misalignment, and provides robustness for the ultrasonic welding process which couples the diaphragm retainer ring to the surgical console. The diaphragm retainer ring is impregnated with a lubricant so to facilitate seating of the displacement sensor with the cassette. A cantilever portion of the diaphragm retainer ring increases a creepage and clearance margin, as well as increases overall part strength in the event of a collision with the displacement sensor and during ultrasonic welding. An insulator is also provided that further increases the creepage and clearance margin.
