20120312554 | Insert Gas Lift Injection Assembly for Retrofitting String for Alternative Injection Location - An insert device can straddle an existing production string port into the annulus such as through an open sliding sleeve so that annulus access into the production string is available. An injection string is associated with the insert to allow placement of the injection fluid at the desired location even if that location is below an isolation packer. The port can be part of an existing ported sub such as a sliding sleeve. Alternatively, the port can be created at a desired location and the insert supported with an anchor so that spaced seals straddle the port that is created to allow injection access from the annulus into the production tubing. The produced fluids pass around the injection tubing and through the insert body to get to the surface. The insert can be removed if needed. | 12-13-2012 |

20090049627 | - Disposable endoscope cleaning device and method, where the device comprises an elongate member, preferably a monofilament and a wiper, or plurality of wipers, formed from a resiliently deformable elastomeric material integrally moulded with the member. The elongate drives the typically disc shaped wiper axially along the lumen axial direction while the wiper remains oriented in a lumen radial plane from adjacent the axial direction to adjacent the lumen wall. The wiper prior has a diameter greater than said lumen internal diameter but is resiliently deformable, preferably not of uniform stiffness in the radial direction, so that it bends in the trailing direction at or near the lumen wall so that a peripheral margin of the wiper contacts the wall in a band extending through 360 degrees of arc. The device allows for cleaning of multiple lumens of differing diameters in an endoscope. | 02-26-2009 |
