Abstract: Disclosed is an improvement to the method for the detection of creatinine in which creatinine, in aqueous solution, is contacted with a dry reagent system of an indicator for creatinine. The assay is carried out at a pH above about 11.5 which is maintained by an alkaline material. The improvement involves packaging the reagent system with a material capable of absorbing CO2 and at least some ambient water vapor. This inhibits the formation of carbonic acid thereby reducing the neutralization of the alkaline reagent system during storage to increase the shelf life and decrease the variability of the system.

Abstract: A method for gravel-packing an interval within a cased wellbore wherein perforations in the well casing are cleaned of any plugging materials before placement of the gravel (e.g., sand). A screen having alternate flowpaths thereon is lowered adjacent the perforated casing and a clear fluid (e.g., clear fracturing gel) is pumped through the perforations into the formation.        The gel cleans the perforation of any plugging material and fractures the formation. A gravel (e.g., sand) slurry is then pumped into the annulus and through the perforations to deposit sand in the fracture, the perforations, and the annulus around the screen. If a sand bridges) forms in the annulus, the alternate flowpaths will deliver the slurry to all levels within the annulus insuring good distribution of sand across the interval.

Title: Acetabular implant with threaded liner and locking ring
Inventor: ROHR WILLIAM L JR
IPC: A61F2/00
Filed: 1997-08-26
Granted: 2003-07-08
Abstract: The acetabular implant of the invention includes a shell having a threaded polarhole with a liner having a threaded polar protrusion extending therefrom for threadable accommodation within the threaded polar hole. Further, the implant includes a locking ring carried by the shell for engagement with the liner. In use, the liner is screwed into the shell by the cooperating threads of the liner and shell. As the liner bottoms out in the shell, the locking ring slides into an annular groove formed in the outer periphery of the shell to lock the liner to the shell. The locking engagement of the locking ring prevents the liner from shifting laterally relative to the shell which therefore prevents the liner from rotating in a direction to loosen the shell relative to the liner. While it is preferred that the liner is formed from a metal, the liner may be formed from either a metal or a plastic dependant upon the clinical requirements for the patient.
