Abstract
A system for retrieving material from a cavity in a patient may include a tube having a proximal end and a distal end, the scope configured to be inserted into the cavity, and a filter assembly disposed between the tube and a vacuum source configured to apply negative pressure through the tube to cause the material to flow through the tube from the distal end to the proximal end, the filter assembly including a filter configured to trap the material in the filter assembly, and allow liquid and gases to pass through the filter assembly.
Claims18
A system, comprising:
- a tube having a proximal end and a distal end, the tube configured to be inserted into a cavity;
- a filter assembly disposed between the tube and a vacuum source configured to apply negative pressure through the tube to cause material to flow through the tube from the distal end to the proximal end, the filter assembly including:
- a filter configured to trap the material in the filter assembly, and allow liquid and gases to pass through the filter assembly,
- a first housing, and
- a second housing removably coupled to the first housing;
- and
- at least one end cap for sealing the first housing after the first housing is decoupled from the second housing;
- wherein the filter assembly is linearly aligned with the tube and the vacuum source, and the filter assembly is a straight linear structure.

A system, comprising:
- a tube having a proximal end and a distal end, the distal end of the tube configured to be inserted into a cavity;
- a filter assembly disposed between the tube and a vacuum source configured to apply negative pressure through the tube to cause material to flow through the tube from the distal end to the proximal end, the filter assembly including:
- a filter configured to trap the material in the filter assembly,
- a first housing, and
- a second housing removably coupled and aligned with the first housing such that the material may flow from a distal end of the first housing to a distal end of the second housing;
- at least one end cap for sealing the first housing after the first housing is decoupled from the second housing;
- and
- an attachment removably coupled to a distalmost end of the tube;
- wherein the filter the filter assembly is a straight linear structure.
