Abstract: A medical lubricant suitable for injection into the blood stream of a patient. The lubricant is suitable for use with rotating equipment such as atherectomy drive shafts moving within sheaths and over guide wires. The lubricant is an oil-in-water emulsion including a surfactant and a co-surfactant. The lubricant can include a cryogenic agent and a pH buffer and be pH adjusted. One lubricant includes olive oil as an emulsified oil, egg yolk phospholipid as a surfactant, sodium deoxycholate as a co-surfactant, glycerin as a cryogenic agent, L-histidine as a pH buffer, and is pH adjusted using sodium hydroxide. The lubricant can withstand freeze/thaw cycles as well as saline dilution, heating, and shear stress without significant creaming, separation, or unacceptable increases in oil droplet size. Compared to saline, the lubricant provides significantly increased lubrication efficiency for rapidly moving parts.

Abstract: It is disclosed that succinic acid and its derivatives that contain a branched aliphatic group on the 2 or alpha position of succinic acid form surfactants that exhibit a high order of or bioresistance to bacteriological degradation. Further, it has been discovered that these novel surfactants can be employed to prepare novel oil-in-water emulsions with lube oils such as mineral oil that are effective as cutting fluids for machining operations but provide an improved resistance to biodegradation to the cutting oil so formulated, without resorting to the inclusion of conventional biocides in the formulation. It has also been discovered that the bioresistance of the cutting fluid emulsion formulation can be further enhanced by using a branched aliphatic hydrocarbon oligomer or polymer as the lubricative component in the formulation. Cutting fluid emulsions so formulated are effective fluids in prolonging tool life and facilitating machining operations.
