Abstract: Devices and methods for retracting tissue, such as bowels and organs, within the body of a patient are generally disclosed. In particular, the present disclosure describes surgical retractors having a series of intersecting strands defining openings there between, wherein the openings are enlargeable by slidable passage of the strands relative to one another. The present disclosure also teaches surgical retractors having a frame that defines a central opening and a supporting structure extending across the central opening and defining a plurality of openings, wherein the frame extends through the openings. In some embodiments, a surgical retractor comprises a monolithic polymeric structure extending across the central opening defined by a frame. Other embodiments and methods are disclosed.

Abstract: Means for attenuating the seating force of a cam-actuated poppet valve such as an exhaust gas recirculation valve in an internal combustion engine including a shock-absorber disposed between the valve stem and valve head. In a currently preferred embodiment, the shock-absorber is a wave washer disposed around the valve stem and captured between the valve stem and the valve head, between which axial motion is allowed. After the valve head engages the valve seat to close the valve, any further travel of the actuator cam and valve stem is absorbed by compression of the wave washer, thus attenuating additional force on elements of the valve actuation train. In opening the valve, the reverse occurs, in that initial motion of the actuator cam and valve stem serves to relieve compression of the wave washer, followed by removal of the valve head from the valve seat.
