Abstract
This application discloses aspiration/biopsy needle apparatus, devices containing these needle apparatus, and methods using these needle apparatus and devices for aspiration or biopsy of samples, in particular biological samples from mammalian subjects. The novel aspiration/biopsy needle systems can find wide applications in the manufacture of fine needle aspiration (FNA)/biopsy devices for convenient cell harvesting and tissue sampling and analysis.
Claims38
An aspiration/biopsy device comprising:
- a body, a cannula needle, and a sample collection container, wherein:
- the body comprises a vacuum channel and a plurality of ports;
- the cannula needle comprises an inlet end positioned at and extending from a first port of the body, an outlet end positioned at and extending from a second port of the body, and a middle portion enclosed inside the body;
- the vacuum channel of the body comprises a first opening end positioned at the second port of the body and a second opening end positioned at a third port of the body in communication with a vacuum source;
- and
- the sample collection container is coupled with the second port of the body, enclosing both of the outlet end of the cannula needle and the first opening end of the vacuum channel;
- wherein the inlet end of the cannula needle is capable of extracting a biological sample from a subject when vacuum is applied on the second opening of the vacuum channel.
