Abstract:
A system for performing a medical procedure and an introducer device suitable for use in the system. The system may be used, for example, to examine and/or to treat the uterus. According to one embodiment, the system includes an introducer, a morcellator, a flexible hysteroscope, and a fluid-containing syringe. The introducer is suitable for transcervical insertion into the uterus and includes a gun-shaped housing and a rigid sheath extending distally from the housing. The sheath is shaped to include an instrument lumen, a visualization lumen, and a pair of fluid lumens. The introducer also includes a first assembly within the housing for receiving the morcellator and for guiding the distal end of the morcellator into the instrument lumen and a second assembly within the housing for guiding the hysteroscope into the visualization channel. In addition, the introducer further includes an assembly for fluidly connecting the syringe to the fluid lumens.

Abstract:
A method and apparatus for finishing a workpiece surface using MR fluid is provided wherein the workpiece is positioned near a carrier surface such that a converging gap is defined between a portion of the workpiece surface and the carrier surface; a magnetic field is applied substantially at said gap; a flow of stiffened MR fluid is introduced into said converging gap such that a work zone is created in the MR fluid to form a sub-aperture transient finishing tool for engaging and causing material removal at the portion of the workpiece surface; and the workpiece or the work zone is moved relative to the other to expose different portions of the workpiece surface to the work zone for predetermined time periods to selectively finish said portions of said workpiece surface to predetermined degrees.
Abstract:
A magnetorheological fluid comprises non-colloidal magnetic particles, an abrasive, water, glycerol, and an alkaline buffer. The abrasive may be CeO.sub.2, the non-colloidal magnetic particles may be carbonyl iron, and the alkaline buffer may be Na.sub.2 CO.sub.3. The fluid is useful for magnetorheological finishing.
