  • Patent number: 8480595
    Abstract: A needle may be fired into tissue by a needle firing mechanism, which may include a fork for holding the needle and a firing rod coupled with the fork. A spring urges the fork to a distal, fired position. A screw gear is coupled with the rod. A sled is positioned at the proximal end of the rod. A catch is configured to engage the sled when the sled is moved to a proximal position. The screw gear is operable to convert rotational motion from a motor and gear set into linear motion to move the rod proximally to engage the sled with the catch, thereby cocking the needle firing mechanism. The motor may also be used to translate the screw gear distally relative to the rod after the sled has engaged with the catch. A trigger is used to fire the cocked needle firing mechanism.

  • Patent number: 8454531
    Abstract: A vacuum control module for use in a biopsy system includes a user interface that presents buttons and icons to control operation of a biopsy device. The icons may indicate, e.g., the position of a cutter relative to a transverse opening, whether the system is in a view sample mode, that an adjacent button is operable to reset the position of a rotatable tissue sample holder, whether the system is in a maintenance vacuum pulse mode, the level of vacuum provided by a vacuum source, the volume level of a speaker, that an adjacent button is operable to place the system in a standby mode, and that an adjacent button is operable to shut down the system. The icons may each have an associated button. The icons may be allocated among separate pages (e.g., a probe page and a system page). Another button may be used to switch between pages.

  • Patent number: 8376957
    Abstract: A biopsy system comprises a biopsy device, a fluid canister, and an auxiliary vacuum source. The biopsy device comprises a body, a needle, a hollow cutter, and a primary vacuum pump. The primary vacuum pump is operable to induce a vacuum in the lumen of the cutter. The fluid canister is configured to receive liquids communicated proximally through the cutter lumen. The auxiliary vacuum source is operable to induce a vacuum in the cutter lumen, thus supplementing the primary vacuum pump. The auxiliary vacuum source may be coupled directly with the fluid canister, such that the fluid canister is positioned along the fluid path between the auxiliary vacuum source and the biopsy device. The biopsy device may further include an integral tissue sample holder. The cutter lumen, the primary vacuum pump, the fluid canister, and the auxiliary vacuum source are all in fluid communication with the tissue sample holder.

  • Publication number: 20120283563
    Abstract: A biopsy system includes a needle, a cutter movable relative to the needle to sever a tissue sample, a processing module, a tissue sensor, and an indicator. The tissue sensor is operable to sense a tissue sample severed by the cutter. The processing module is operable to drive the indicator based on information from the tissue sensor. The indicator may include an audible indicator and/or a visual indicator. The indication provided by the indicator may vary based on sensed qualities of the tissue sample. The indicator may be integrated into a biopsy instrument or may be provided as part of a remote unit. The biopsy system may also include a multi-chamber tissue sample holder. A graphical user interface may indicate which chambers of the tissue sample holder are occupied by tissue samples.

  • Patent number: 8251916
    Abstract: A biopsy device includes a cutter defining a cutter lumen and a tissue sample holder for collecting tissue samples. In one example, the tissue sample holder has a rotatable manifold that is configured to redirect fluid from one axial direction to an opposite axial direction. The tissue sample holder also has a plurality of tissue sample trays through which fluid may be communicated. The tissue sample trays define chambers that are each configured to separately hold tissue samples. The tissue sample trays are removable relative to the manifold. A cup is configured to cover the manifold and trays. A tissue sample holder rotation mechanism is operable to rotate the manifold to successively index each chamber of the tissue sample trays with the cutter lumen. A feature may prevent rotation of the manifold when one part of the biopsy device is separated from another part of the biopsy device.

  • Patent number: 8068895
    Abstract: An instrument for deploying a marker at a site within a patient may include an elongate cannula, an elongate pusher, and a marker disposed within the cannula. The cannula may have a tip at its distal end and a transverse opening. The pusher may be disposed within the cannula, and may be moved longitudinally within the cannula. The pusher may have a ramped distal end. The marker may be configured to exit the transverse opening upon urging by the ramped distal end of the pusher. In some versions, the tip of the cannula has a flat proximal face, and the marker has a recessed region that is configured to buckle in response to longitudinal compression, such that the marker will pop out of the cannula upon buckling. In other versions, the cannula has an external sheath, an open and curved distal end, or a leaf spring.

  • Publication number: 20110218433
    Abstract: A biopsy site marker delivery device includes a relatively flexible marker deployer tube having a closed distal end, a push rod slidably disposed within the tube, and at least one marker disposed in the tube. The deployer tube includes a side exit port with an adjacent ramp for transversely dispensing the marker upon distal advancement of the push rod within the tube. An elongate member such as a sleeve is operable to guide and/or stabilize the flexible deployer tube as the tip of the tube is inserted into an access channel such as a channel provided by a cannula or biopsy device. An internal package member is configured to support the marker delivery device and the elongate member, with the elongate member being positioned over the side exit port to prevent the marker from inadvertently exiting the side exit port.

  • Publication number: 20110201964
    Abstract: A tissue sample holder for a biopsy device comprises an outer cup, a collection tray, and a flow restriction device. The outer cup defines a hollow interior. The collection tray separates the hollow interior into an upper chamber and a lower chamber while allowing fluid to pass between the two chambers through an opening in the collection tray. The flow restriction device selectively seals the opening thereby preventing fluid from passing from the lower chamber into the upper chamber. The flow restriction device may be operable to selectively seal the opening in response to a vacuum being induced within the upper chamber. The collection tray may have a shape (e.g., tapered, funnel-shaped, convex, etc/) selected to facilitate the flow of fluid toward the opening. The lower chamber may be coupled with an external fluid collection device. The lower chamber may define a larger volume than the upper chamber.

  • Patent number: 7981049
    Abstract: A biopsy system includes a biopsy device, a vacuum canister, a vacuum control module, and a plurality of tubes. A first tube is configured to provide an axial vacuum to the biopsy device, while a second tube is configured to provide a lateral vacuum. A third tube is configured to communicate atmospheric air to the second tube. A fourth tube is configured to communicate saline to the second tube. The vacuum canister is configured to collect fluids drawn through the first tube and the second tube. The canister has a lid with trenches formed in it for retaining the first, second, third, and fourth tubes.
