Devices and methods for portable, adjunctive vacuum source and cytology/histology collection systems for biopsy devices

A method, comprising:

• providing a collection device comprising a main body element, an inner element co-axially disposed within the main body element and spaced away therefrom, a fluid and tissue collection chamber defined by a space extending at least partially between an inner wall of the main body element and an outer wall of the inner element and a vacuum pump attached to the main body element, a sealed vacuum channel extending between the inner element and the vacuum pump, the vacuum pump comprising an exhaust port, the inner element being configured to receive a specimen collection chamber of an interventional medical device instrument;
• coupling the collection device to the specimen collection chamber of the interventional medical device instrument;
• and
• turning the vacuum pump on and drawing at least one of fluid and tissue from the specimen collection chamber of the interventional medical device instrument through the sealed vacuum channel, out of the exhaust port and into the fluid and tissue collection chamber.

• coupling the collection device to the specimen collection chamber of the interventional medical device instrument;
• turning the vacuum pump on and drawing at least one of fluid and tissue from the specimen collection chamber of the interventional medical device instrument into the fluid and tissue collection chamber of the collection device through a sealed vacuum channel,
• removing the collection device with collected fluid and tissue received therein from the interventional medical device instrument;
• and
• providing a spare duplicate of the collection device and intra-operatively coupling the spare duplicate of the collection device to the specimen collection chamber of the interventional medical device instrument.
