Biopsy devices, systems, and methods

Abstract

Various embodiments are generally directed to biopsy devices, systems, and methods for tissue sample acquisition, such as during fine-needle aspiration. Several embodiments are particularly directed to biopsy devices with features to facilitate accessing, acquiring, and/or retaining one or more tissue samples from a target biopsy site. In one embodiment, for example, a biopsy device may include an elongate member having an insert disposed within a lumen of an elongate member. The insert may be configured to mate with a needle disposed in the lumen to maintain a rotational orientation of the needle. In another embodiment, a needle may include multiple openings for acquiring a tissue sample. In yet another embodiment a helical component may be disposed in a needle lumen to acquire and retain tissue samples.
