Abstract: Systems and methods for tracking dosage periods are disclosed. The systems and methods may include setting a timer (140) to a predetermined value corresponding to a dosage period in response to the engagement of a cover (110) to a container (120). An indication may be provided that corresponds to a remaining period in the dosage period set by the engagement of the cover (110) and container (120). The indication may also indicate a remaining time period in the dosage period.
Abstract: In one characterization, the present invention relates to a radiation-shielding assembly for holding a container having a radioactive material disposed therein. The assembly may, at least in one regard, be referred to as an elution shield and/or a dispensing shield. The assembly includes a body at least partially defining a cavity. There is at least one opening through the body into the cavity. The assembly may include a cap that at least generally hinders escape of radiation from the assembly through the opening. The cap may be releasably attached to the body in one orientation and may establish non-attached engagement with the body in another orientation. The assembly may include an adjustable spacer system for adapting the assembly for use with containers having different heights.

Abstract: A method of performing cardiac surgery on a patient's heart, including covering a patient with an inflatable blanket for a forced air convection system, the inflatable blanket having at least one separable seal line within the blanket. The separable seal line may be separated to form a slit. A patient's femoral artery is accessed through the slit, and an elongate medical instrument is passed through the slit, and through the femoral artery toward the patient's heart. Cardiac surgery is performed with the elongate medical instrument, and the elongate medical instrument is withdrawn from the femoral artery through the slit.

Abstract: A process for the purification of an impure preparation containing naltrexone by means of a reverse phase preparative chromatography process is provided. In an illustrative embodiment a chromatographic column is loaded with a stationary phase, typically a silica particle having an organic ligand bound thereto. With a loading ratio of from about 10 to about 1000 the impure preparation is acidified and passed through the column. The column is eluted with typically an aqueous solution with acetonitrile and the purified naltrexone is obtained in a specified fraction.
Abstract: A pharmaceutical pig is used to transport a syringe containing a liquid radiopharmaceutical from a radiopharmacy to a medical facility for administration to a patient. The pharmaceutical pig includes an elongate polymer cap that is removably attached to an elongate polymer base. The elongate polymer cap includes a cap shell that completely encloses a cap shielding element and the elongate polymer base includes a base shell that completely encloses a base shielding element. Preferably the polymer utilized for the cap shell and the base shell is polycarbonate resin, e.g., LEXAN®. An inner liner is not utilized and the cap shielding element and the base shielding element, which are preferably, but not necessarily, made of lead, are completely sealed and unexposed.
