The present invention provides a practical, multi-polar, in-line connector system for use in connecting implantable medical devices (IMD) and associated non-standard, low profile medical electrical leads. In addition, the present invention provides a system that uses tool less, frictional, sealed, compressive electrical connections for most or all of the electrical interconnections between an IMD and a low profile lead. A protective sleeve seals the lead connector to the non-standard port to prevent intrusion of body fluids therein. In addition, optional microchip-based circuitry coupled to the sleeve enables wireless communication and remote programming for diverse IMDs. Memory associated with the circuitry can store, update and reprogram a wide variety of information relevant to the IMD, the patient, and the attending physician, among others. For example, the microchip may be used to identify the lead type and characteristics, as well as other useful data.

The object of the present invention is to provide a powder cerium-based abrasive which enables the preparation of a cerium-based abrasive slurry, in which the dispersed state of the abrasive particles is maintained for a long period of time, simply by blending it with a dispersion medium such as water and which makes easier the after-treatment of the abrasive slurry having been used. The cerium-based abrasive of this invention is a cerium-based abrasive including chlorine-containing compounds in which chlorine (element) is contained in amounts, in terms of total mass, equivalent to 0.05% to 5.0% of the mass of the total rare earth oxide contained therein. An abrasive slurry including the abrasive of this invention as a solid content is superior in dispersion maintaining properties of its abrasive particles. Accordingly, an abrasive slurry having a stable concentration of the solid content can be supplied continuously. Further, the abrasive requires no dispersant for maintaining its dispersed state, and hence separation treatment for a dispersant is unnecessary after the abrasive has been used. Thus, the abrasive according to the present invention makes simpler the after-treatment of the abrasive slurry after use.
