Abstract: A method of using a biopsy apparatus includes moving a stylet cannula relative to a vacuum cannula between a first extended position and a first retracted position; and receiving a protrusion member within a flared portion of the vacuum cannula when the stylet cannula is in the first retracted position.

Abstract: A biopsy apparatus includes a piercing module having a probe drive slider coupled to a probe carrier body of a biopsy probe assembly, and has a primed position and a fired position. A nut housing has a home position and an extended position. A drive spindle is drivably coupled to a motor driveshaft, and is coupled to the nut housing. A firing spring is interposed between a motor housing and the probe drive slider. A release arm is pivotably coupled to a piercing module frame. When the probe drive slider is in the primed position and the release arm is in a latch position, the release arm is positioned to engage the probe drive slider to hold the probe drive slider in the primed position. A release slider releases the release arm from the latch position when the nut housing is moved from the home position to the extended position.

Abstract: A biopsy apparatus includes a biopsy probe assembly that is releasably attached to a driver assembly. The biopsy probe assembly has a vacuum cannula and a stylet cannula coaxially arranged. The vacuum cannula has a flared portion that extends distally from an elongate portion. The stylet cannula is movable between a first extended position and a first retracted position. The stylet cannula has a distal portion having a sample notch and a protrusion member that extends proximally in a lumen of stylet cannula along a portion of a longitudinal extent of the sample notch, wherein when the stylet cannula is in the first retracted position, the protrusion member is received within the flared portion of the vacuum cannula. The biopsy apparatus may further include a controller circuit that has a virtual energy reservoir, and the controller circuit executes program instructions to control current to motors when engaging dense tissue.

Abstract: A dual lumen coaxial introducer, for use with an elongate needle, includes a hub, an elongate member, and a pushrod. The elongate member has a first lumen, a second lumen, a proximal end portion, and a distal end. The proximal end portion is fixedly attached to the hub. The first lumen of the elongate member defines a longitudinal axis and is configured to slidably receive the elongate needle. The pushrod is located in the second lumen of the elongate member. The pushrod has a distal end surface. The pushrod is movable in the second lumen between a retracted position and an extended position. In the retracted position, the distal end surface of the pushrod is spaced away from the distal end of the elongate member to define a marker recess in the second lumen elongate member for carrying a tissue marker for delivery to a delivery site in a patient.

Abstract: A biopsy apparatus includes a biopsy needle, a sample manifold, and a sample container. The sample manifold is coupled to the biopsy needle. The sample manifold has a receptacle and an insertion axis. The sample receptacle has an interior side wall and a mounting pin that projects inwardly from the interior side wall toward the insertion axis. The sample container is configured for insertion into the receptacle. The sample container includes a cap portion, a basket portion, and a hinge, wherein the cap portion is joined to the basket portion by the hinge.

Abstract: A sample collection container for a biopsy apparatus includes a sample capture body defining an interior space. The sample capture body is made of a fabric and has an interior sample capture surface that at least partially surrounds the interior space. The fabric has at least one fold.

Abstract: A biopsy apparatus includes a housing, a biopsy cannula mounted to the housing, and a cannula rotation mechanism mounted to the housing. The cannula rotation mechanism has a thumbwheel, a first gear, and a second gear. The thumbwheel is configured to rotate about a rotational axis, with the rotational axis being perpendicular to the longitudinal axis of the biopsy cannula. The first gear is mounted in fixed attachment to the thumbwheel. The second gear is mounted in fixed attachment to the biopsy cannula. The first gear is in mesh with the second gear such that the first gear is directly drivably engaged with the second gear to rotate the biopsy cannula about the longitudinal axis when the thumbwheel is rotated.

Abstract: A biopsy device includes an elongate member and a tissue anchor. The elongate member has a lumen and a sample receiving notch. The sample receiving notch has a proximal end wall, a distal end wall, and a floor between the proximal end wall and the distal end wall.
