Abstract
A medical apparatus having an elongate tubular body with a proximal end, an opening at the proximal end, and a distal end defining an interior space therebetween and the distalmost end of the elongate tubular body is configured to matingly engage a filter assembly; a filter assembly configured to matingly engage the distal portion of the elongate tubular body and to provide a seal with the interior space thereof, the filter assembly comprising a filter membrane and a border that is sectionable for mounting on a slide for analysis on a microscope; and a base member configured to releasably engage the distalmost end of the elongate tubular body and to receive the filter assembly therein.
Claims20
A centrifigable medical separation apparatus, comprising:
- an elongate tubular body, comprising
- a proximal end and an opening at the proximal end.
- a distal end opposite the proximal end and an opening at the distal end,
- the elongate tubular body defining an interior space therebetween, and the elongate tubular body having a distal portion configured to matingly engage a filter assembly;
- and
- a filter assembly configured to matingly engage the distal portion of the elongate tubular body,
- the filter assembly being configured to accommodate at least one filter membrane therein,
- the centrifugable medical separation apparatus configured for insertion into a centrifuge such that centrifugation encourages material within the interior space toward the distal opening.
A centrifugable medical separation apparatus, comprising:
- an elongate tubular body, comprising
- a proximal end and an opening at the proximal end,
- a distal end opposite the proximal end and an opening at the distal end,
- a filter assembly matingly engagable with a distal potion of the elongate tubular body,
- the filter assembly having at least one filter membrane therein,
- the filter assembly having a cellular sample disposed therein, and
- the centrifugable medical separation apparatus configured for insertion into a centrifuge such that centrifugation of the centrifugable medical separation apparatus encourages material within the interior space toward the distal opening.
A centrifugable medical separation apparatus, comprising:
- an elongate tubular body having a proximal end and a distal end,
- the elongate tubular body defining an interior space therebetween, and
- the elongate tubular body being sized to fit within a centrifuge;
- and
- a filter assembly,
- the filter assembly matingly engaged with a distal portion of the elongate tubular body,
- the filter assembly having at least one filter membrane disposed therein, and
- the centrifugable medical separation apparatus configured for insertion into a centrifuge such that centrifugation encourages material within the interior space toward the distal opening.
