Abstract: A trans-anastomotic insertion device includes a body having a distal portion, a proximal portion, and a central portion. The distal portion has a blunt distal end, a width that decreases from its distal end to its proximal end, and longitudinal ribs that provide rigidity to the distal portion. The central portion has a circular configuration and includes a proximally facing surface that includes protrusions that are positioned to be received within staple pockets of a reload assembly of a stapling device. The proximal portion includes a central post that includes splines that are received between splines on a shell housing of a stapling device. The configuration of the insertion device provides added strength to the insertion device to resist high torsional forces that may be applied to the insertion device during insertion of a surgical device through an incision into a body cavity.

Abstract: A surgical stapling device includes a reload assembly that includes a dual-detent system to retain a knife carrier of the reload assembly in a retracted position after the stapling device is fired. The dual detent system includes auxiliary and primary detents to improve the retention force of the knife carrier to minimize the likelihood of inadvertent readvancement of the knife carrier and annular knife.

Abstract: A method of making an infrared detector assembly (10) with integrated temperature sensing comprises forming at least one IR sensitive element (12,14) on a substrate (16) and forming conductive electrode pads (22,24,26,28,30,32) for (a) IR sensitive element and (b) at least one thermistor (34) on the substrate. The conductive electrode pads and the IR sensitive element are in a centerline symmetrical configuration in which the conductive electrode pads and the IR sensitive element, taken together, are centerline symmetrical about at least one axis (36,38) in a plane of the infrared detector assembly, wherein the centerline symmetrical configuration is operable to reduce a thermal lag time between a temperature of the at least one thermistor and a temperature of the IR sensitive element during temperature transients.

Abstract: A respiratory nosepiece (10) and method of manufacturing the respiratory nosepiece, the respiratory nosepiece including a first nasal prong (110) with a first channel (112) extending there through, and a first side port (130) connectable to tubes (192, 194) having different first and second diameters. The first side port has a second channel (131) extending there through and in communication with the first channel. The second channel includes a first section (134) having the first diameter, a second section (136) having the second diameter, a first step (135) between the first and second sections, and a second step (137) between the second section and an end (133) of the second channel. The first and second channels are formed during injection molding by pins (412, 422, 431, 441) having flat pin-on-pin geometry to reduce resin flash within the channels.

Abstract: A detector to measure composition of a flow of gas from a respiratory circuit. The detector includes a housing and a removable flow path element. The removable flow path element includes an inlet, a sampling chamber, a pump section including a membrane and an actuator interface, and an outlet. A flow path element dock is formed by the housing with the flow path element dock to removably engage the removable flow path element. A radiation source within the housing emits radiation into a sampling chamber of the removable flow path element while the removable flow path element is docked in the flow path element dock. A sensor is housed within the housing. A pump actuator and controller are within the housing to drive the pump to maintain the flow rate of the flow of breathable gas through an enclosed flow path.
