Title: Medical emulsion for lubrication and delivery of drugs
Inventor: LYONS ROBERT T
IPC: A61K31/427
Filed: 2001-03-23
Granted: 2011-03-15
Abstract: A medical lubricant suitable for injection into the blood stream of a patient.  The lubricant is suitable for use with ro-tating 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 can also include a therapeutic agent.  The lubricant can withstand freeze/thaw cycles as well as saline dilution, heating, and shear stress without significant creaming, sep-aration, or unacceptable increases in oil droplet size. Compared to saline, the lubricant provides significantly increased lubrication efficiency for rapidly moving parts.

Le manchon d'engagement d'endoprothèse est utilisé afin d'engager par friction une endoprothèse, en étant monté dessus, de façon à empêcher l'endoprothèse de glisser, lors de son déploiement, de façon proximale par rapport au cathéter interne. Le système comprend, en outre, une endoprothèse auto-expansible du type comprenant un maillage tricoté de fil en nitinol souple à la fois selon des axes radial et longitudinal. L'endoprothèse est montée sur le manchon d'engagement d'endoprothèse dans un état étiré longitudinalement et il est maintenu, jusqu'à son déploiement, dans l'état étiré à l'aide d'un manchon de retenue. Le manchon de retenue, qui entoure coaxialement l'endoprothèse et dont la taille appropriée permet de maintenir l'endoprothèse dans l'état étiré, est constitué d'un tube formé directement sur l'endoprothèse. Le système comprend aussi un cathéter externe qui entoure une grande partie de l'extrémité distale du cathéter interne jusqu'à son embout, la cathéter externe étant conçu pour être déplacé axialement par rapport au cathéter interne. L'extrémité distale du cathéter externe, mécaniquement couplée à l'extrémité distale de l'endoprothèse pour un déplacement axial, comporte un diamètre interne augmenté afin de s'adapter aux composants positionnés entre les cathéters interne et externe. Afin de faciliter l'avancée du cathéter externe sur le manchon de retenue de l'endoprothèse lors de l'assemblage du système, le cathéter externe comporte une échancrure fabriquée depuis son extrémité distale. Après positionnement du cathéter externe sur le manchon de retenue de l'endoprothèse, l'échancrure est scellée.
