    Abstract: A closure device includes a first ring structure having a first distal portion and a first medial portion and a second ring structure having a second distal portion and a second medial portion. The first and second distal portions are movable between an open position, where the first and second distal portions form an angle relative to one another for receiving target tissue therebetween, and a closed position, where the first and second distal portions are drawn toward one another for gripping the target tissue. The device also includes an anvil about which the first and second medial portions are formed. Either one of proximal motion of the anvil relative to the first and second rings or proximal motion of the medial portions relative to the anvil causes the first and second distal portions to move into either one of the open position or the closed position.

    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.
