Abstract: Medical devices with male luer lock fittings with either a male conical tip having a roughened outer surface or a female luer lock fitting with a roughened surface and methods for manufacture and use are disclosed. The outer surface of the male conical tip or a surface of the female luer lock fitting is roughened to decrease the likelihood of breakage during disassembly from a female luer lock fitting of another medical device in the presence of a liquid.

Abstract: A bearing housing comprising an annulus having an aft side and a forward side, a barrier extending from the aft side to the forward side to form a first and second zone, a first opening in the first zone extending through the forward side, and a second opening in the second zone extending through the forward side at least a portion of the first opening being at a level lower than a lowermost level of the second opening.

Abstract: A system for hanging a drop light from a wide variety of irregularly shaped objects at varying angles and orientations while providing superior stability, and greater freedom of choice for hanging locations. The hanger system is comprised of a plurality of flexible hangers grouped together and mounted to a drop light, which when forced over an object, tend to deflect snapping back into their preferential shape in accordance with the geometry of the object. As the flexible hangers snap back into their preferred position over the object they provide secure and stable support for the drop light. As the drop light is removed the flexible hangers deflect out of their grasping shape sliding past the mounting object allowing removal from the mounting object.
