  • Patent number: 6391832
    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 and other minimally invasive medical devices introduced into a patient through a catheter like instrument. The lubricant is an oil-in-water emulsion including a surfactant, a co-surfactant, and a pH buffer. The lubricant can further include a cryogenic agent and a pH adjusting agent. 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 also includes a therapeutic agent. 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.
    Type: Grant

  • Patent number: 6054421

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.
