Abstract: A filter cartridge for a surgical gas delivery system is disclosed which includes a housing having a front end and a rear end and defining a first interior flow path extending downstream from a first inlet at the rear end of the housing to a first outlet at the front end of the housing, and a second interior flow path extending upstream from a second inlet at the front end the housing to a second outlet at the rear end of the housing, a first pleated filter element operatively associated with the first interior flow path, a second pleated filter element operatively associated with the second interior flow path, and a carbon filter disc operatively associated with the second interior flow path and positioned adjacent a downstream side of the second pleated filter element.

Abstract: A trocar assembly includes a trocar including an elongated tubular member extending between a distal end configured to be inserted into a surgical site and a proximal end including a housing configured for introduction of surgical instruments into the tubular member. The housing includes a pair of opposed latch receptacles. An obturator is assembled into the tubular member of the trocar. The obturator includes an elongated obturator body extending from a trocar cover to an opposed obturator tip. The trocar cover includes a rim for engaging the housing of the trocar. The trocar cover includes a pair of opposed latches extending radially inward from the rim, wherein the latches are releasably latched to the latch receptacles of the trocar. The trocar cover includes a compliant mechanism operatively connected to release the latches from the latch receptacles.
