Abstract: Various exemplary devices, systems, and methods for anti-stick coatings for surgical tools are provided. In general, a method of manufacturing a surgical tool includes forming, using plasma enhanced chemical vapor deposition with hexamethyldisiloxane as a precursor material, a coating on a conductive tissue treating surface of an end effector, the coating comprising a silicone material, wherein the coatings are effective to prevent tissue sticking to the jaws during an electrosurgical procedure.

Abstract: Various exemplary devices, systems, and methods for multi-layer anti-stick coatings for surgical tools are provided. In general, a method of manufacturing a surgical tool includes forming, using plasma enhanced chemical vapor deposition with hexamethyldisiloxane as a precursor material, a first coating on a conductive tissue treating surface of the end effector and a second jaw component of the end effector, the first coating comprising a first material, wherein the first material is a first silicone material, and applying a second coating on top of the first coating on the first jaw component and the second jaw component, the second coating comprising a second material, wherein the coatings are effective to prevent tissue sticking to the jaws during an electrosurgical sealing procedure.

Abstract: A valve for use in a vehicle damper provides a predictable, repeatable clamping force without requiring close tolerancing of parts. The valve includes a valve body having a compression orifice and a rebound orifice extending therethrough. The valve assembly further includes a rebound disk located adjacent the first surface and covering the rebound orifice, and a compression disk located adjacent the second surface and covering the compression orifice. The valve includes a fastener having a head and a shaft extending through the valve assembly, the fastener holding the valve body, the rebound disk and the compression disk in close engagement such that when the valve assembly is immersed in fluid, fluid can be forced through the compression orifice when the pressure of the fluid urges the compression disk away from the compression orifice and fluid can be forced through the rebound orifice when the pressure of the fluid urges the rebound disk away from the rebound orifice.

Abstract: A damper piston assembly includes a rod, a piston, a rivet disk, and a spring. The piston surrounds the rod between a riveted end and a longitudinal stop of the rod. The piston includes a valve assembly having a valve body with an orifice extending therethrough. The rivet disk surrounds the rod and has an opening for fluid communication with the orifice. The rivet disk is longitudinally secured between the piston and the riveted end of the rod. The spring is positioned in compression longitudinally between the rivet disk and the longitudinal stop of the rod.
