Abstract: An abrading head for a high-speed rotation atherectomy device is disclosed. The head has its center of mass laterally displaced from the rotational axis of the drive shaft. As the drive shaft spins, centrifugal force forces the abrading head radially outward. At high speeds, and the abrasive portion of the head may subtend an abrading cylinder larger than at low speeds or at rest. The abrading head has two components, each having a different density. The connection portion may be an incomplete cylinder, which fastens onto the drive shaft, and may be a relatively low density metal, such as stainless steel. The eccentric portion may be a relatively high density metal, such as tungsten or tantalum, and is attached to the connection portion.

Abstract: According to one aspect of the disclosure, a portable fluid storage device comprises a fluid impervious container having an interior space for the collection of human waste and a hollow tailpiece removably extending from the fluid impervious container and providing sealed fluid communication between an inlet end of the hollow tailpiece and the interior space. A cap is removably disposed at the inlet end of the hollow tailpiece and has a lumen disposed therethrough to provide a point of entry for the human waste into the portable fluid storage device. A flexible conduit is movably disposed within and removable from the hollow tailpiece and has an inlet end removably connected to an outlet end of the cap and an outlet end in fluid communication with the interior space of the fluid impervious container.
