A biopsy device includes an elongated housing having a manifold, an outer cannula partially and slidably disposed in the manifold, and an inner cannula partially and slidably disposed in a lumen of the outer cannula. The biopsy device further includes an outer cannula seal disposed between the manifold and the outer cannula, the outer cannula seal including an interference ring portion disposed adjacent an inner surface of the manifold, a beaded ring portion that contacts an outer surface of the outer cannula, and a flexible portion extending between the interference ring portion and the beaded ring portion.

A core biopsy system includes a core biopsy needle device and biopsy sample collection device, wherein the core biopsy needle device is positionable within and movable with respect to the biopsy sample collection device. Systems and methods for obtaining multiple biopsy samples with a single insertion of a needle of the biopsy needle device include obtaining sequential samples and storage in a multi-cell cartridge. Additional features and methods of the invention include obtaining two sample portions from each sample acquisition, wherein each of the two sample portions can be separately preserved and analyzed.

One or more methods for sampling gingival metabolites and biomarkers.

An apparatus for individually storing multiple tissue samples separately from each other includes a base, a lid, a lock, and one or more vents. The base defines a plurality of reservoirs and a plurality of identification areas. A portion of the base defines an opening corresponding to each reservoir. The lid is configured to secure the multiple tissue samples within a corresponding reservoir by enclosing each corresponding opening in the closed configuration. The lock is configured to selectively lock the lid against the base in the closed configuration. The one or more vents are configured to enable entry of fluid into the reservoirs when the lid is in the closed configuration. The one or more vents are further configured to prevent exit of tissue samples from the reservoirs when the lid is in the closed configuration.

A biopsy apparatus includes a cannula assembly having a cannula hub and a cutting cannula. A stylet assembly has a stylet hub and a stylet. The stylet is coaxial with the cutting cannula. An operator mechanism is configured to effect axial movement of the stylet hub and the cannula hub. The operator mechanism has a head portion configured to releasably engage the stylet hub and an arm member configured to releasably engage the cannula hub. The stylet hub is configured to be rotationally movable between an engaged position and a disengaged position, wherein in the engaged position the stylet hub is releasably connected to the head portion of the operator mechanism, and in the disengaged position, the stylet hub is disconnected from the head portion of the operator mechanism to facilitate axial movement of the stylet assembly in a proximal direction independent of the operator mechanism.

An endoscope for removing tissue at a surgical site includes an elongated tubular body insertable within a mammalian cavity of a patient. An instrument channel extends between a first opening at a distal end and a second opening at a proximal end of the tubular body and is sized and configured to receive a surgical cutting assembly that includes an aspiration channel configured to remove material entering the endoscope via a distal end of the surgical cutting assembly. A torque generation component configured to generate torque is positioned within the distal end and configured to provide the generated torque to a coupling component. The coupling component is positioned at the distal end of the elongated tubular member and configured to actuate a cutting component of the surgical cutting assembly responsive to actuation of the torque generation component.

A biopsy device includes a body, a needle, a hollow cutter, and a tissue sample holder. The needle extends distally from the body and includes a lateral aperture. The cutter is movable relative to the needle to sever a tissue sample and defines a cutter lumen. The tissue sample holder includes a manifold and an outer cover. The manifold includes a plurality of passages and an indexing portion. Each passage of the plurality of passages is configured to selectively index relative to a proximal end of the hollow cutter. The outer cover includes a resilient member. The resilient member is configured to engage with the indexing portion of the manifold to selectively index a passage of the plurality of passages with the distal end of the hollow cutter.

A tissue handling system includes a biopsy device and a tissue storage container separate from the biopsy device. The biopsy device has a cutting cannula, a housing, and a tissue collecting device. The tissue collecting device is detachably received in the housing. The tissue collecting device is configured to receive at least one tissue sample. The tissue storage container is configured to detachably receive the tissue collecting device after the tissue collecting device is disengaged from the housing of the biopsy device to deliver the at least one tissue sample from the tissue collecting device to the tissue storage container.

A core needle biopsy device includes a body, a needle assembly and a drive assembly. The needle assembly extends distally from the body and includes a hollow piercer and a hollow cutter. The piercer is disposed within the cutter. The cutter includes a distal tip and a swaged portion proximate the distal tip. The drive assembly is configured to selectively cock and fire the piercer and the cutter.

Provided herein are methods and a device for collecting biological samples. In particular, the present disclosure relates to a device designed to specifically capture samples within the target areas of a patient for specific cell collection for particular diagnosis.
