An automated fine needle biopsy device is described for extracting tissue from the body predominantly in suspected cases of breast cancer. However, it can be used in other parts of the body accessible to needle biopsy. The device causes a fine needle, which is attached to the device, to reciprocate and/or rotate at the same time causing tissue to enter the needle. The depth and number of the thrusts can be pre-programmed, and the force behind each thrust is constant. Suction may or may not be used. The tissue extracted is subsequently expelled onto glass slides for microscopic interpretation. This device and method offer a vast improvement over the present method for fine needle biopsy wherein it is performed manually and in a very haphazard way. The prime deficiency of the manual method currently used is insufficient tissue extraction. This device will correct that situation enabling accurate diagnosis to be made on adequate tissue samples obtained.

A method and device for obtaining the type of gastric mucosal coating of a human being's upper gastrointestinal tract to enable a double-contrast study of said tract to be performed are disclosed. The method comprises the steps of providing an open-ended feed tube having first and second ends, and having a vent in the feed tube for the introduction of ambient air. The vent comprises venting means which are disposed in a direction towards the second end of the feed tube. The first end of the feed tube is disposed into a supply of contrast medium and the medium is ingested by sucking from the second end of the feed tube while simultaneously ingesting air through the venting means. The venting means define a vent opening which is large enough to permit ingestion of a sufficient amount of air to effect a desired degree of distention of the organs in the tract and small enough to prevent interference with the ingestion of the contrast medium, whereby the gaseous distention enhances the gastric mucosal coating and enables a double-contrast study of the organs to be performed.
