Abstract
A device for tissue sampling that comprises a needle, a stylet and a sealing member. The needle comprises a distal tip, a proximal end, and one or more interior portions. The needle extends along a longitudinal axis extending between the distal tip and the proximal end. The stylet is moveably supported within the one or more interior portions of the needle. The sealing member Is moveably supported within the one or more interior portions of the needle and substantially conforms to the one or more interior portions, The distal tip is configured to obtain a tissue sample. The stylet and the sealing member are movable, along the longitudinal axis away from the distal tip so that a local vacuum is created at the distal tip so that obtained tissue samples can be aspirated into the needle.
