    摘要： A tissue cutting member includes a distal tubular portion having a side wall defining a lumen, a longitudinal axis, and a flared distal section. The flared distal section has an inclined distal tip and an outwardly flared distal tubular portion that defines an inner tissue receiving aperture. The inclined distal tip has a beveled front face with a leading tissue cutting edge and a trailing cutting edge. A single longitudinally oriented opening is in the side wall in the flared distal section which radially opens to the lumen. The longitudinally oriented opening has an open distal end and is configured to extend from a closed proximal end to the open distal end. The closed proximal end has a relief opening with a transverse dimension larger than a transverse dimension of the longitudinally oriented opening adjacent the relief opening. The longitudinally oriented opening diverges to intersect the trailing cutting edge.

    摘要： A method for collecting a tissue specimen from a target site within a patient includes rotating an elongated tubular section about a longitudinal axis to provide a desired aperture orientation of a tissue receiving aperture; applying a vacuum within the elongated tubular section to draw tissue at the tissue site through the tissue receiving aperture of the elongated tubular section into the interior thereof; advancing an elongated tissue cutting member longitudinally within the elongated tubular section to cut a tissue specimen from the tissue extending into the elongated tubular section; and applying a vacuum to the proximal end of the elongated tissue cutting member for transporting a cut tissue specimen through the inner lumen of the elongated tissue cutting member to discharge the cut tissue specimen directly from the proximal end of the elongated tissue cutting member into a tissue collection device.

    摘要： A method for forming a tissue cutting member includes: providing a single longitudinally oriented opening in a side wall in a flared distal section of a distal tubular portion which radially opens to a lumen of the distal tubular portion, the single longitudinally oriented opening having an open distal end and extending from a closed proximal end to the open distal end; and providing a relief opening at the closed proximal end of the single longitudinally oriented opening, the relief opening having a transverse dimension larger than a transverse dimension of the single longitudinally oriented opening adjacent the relief opening, the single longitudinally oriented opening diverging from the closed proximal end to intersect a trailing cutting edge of a beveled front face of the inclined distal tip of the distal tubular portion and facilitating formation of the outwardly flared distal tubular portion.

    摘要： The invention is directed to devices and methods for separating and collecting a tissue specimen from a patient's target site. The device includes a probe member with a penetrating distal tip and a tissue receiving aperture, and a tissue cutting member which is rotatable disposed within the probe member to cut a tissue specimen drawn into the interior of the device through the aperture. The longitudinal edges of the aperture are preferably sharpened to engage the cutting edges of the tissue cutting member. Vacuum may be provided in the inner lumen of the cutting member to transport tissue therethrough. Rotation, rotational oscillation and/or longitudinal reciprocation of the tissue cutting member is effective to separate a tissue specimen from surrounding tissue. An accessing cannula having an tissue receiving aperture may be concentrically disposed within the probe member and about the tissue cutting member. The tissue cutting edge of the tissue cutting member preferably is longitudinally oriented and may have a cutting angle less than 90° with respect to the longitudinal axis of the tissue cutting member.

    摘要： An apparatus for collecting one or more tissue specimens includes a tissue specimen collector having a cannula receiving opening, a vacuum opening, and an interior. The vacuum opening is on a first axis, and the cannula receiving opening is on a second axis. A removable tissue specimen retaining member is positioned within the interior of the tissue specimen collector. The removable tissue specimen retaining member has a plurality of openings that are interposed between the first axis of the vacuum opening and the second axis of the cannula receiving opening. The removable tissue specimen retaining member is movable along the second axis. An elongated tissue cutting member extends through the cannula receiving opening of the tissue specimen collector to position a proximal end of the elongated cutting member in the interior above the plurality of openings of the removable tissue specimen retaining member.

    摘要： A biopsy device includes an elongated probe having a central longitudinal axis, a proximal end, a distal end, and an aperture. A tissue penetrating tip includes a proximal base secured to the distal end of the probe. A sharp distal point distal to the proximal base lies on the central longitudinal axis. Each of a first, second and third concave surface is configured to extend from the base to the sharp distal point. The second concave surface is located to intersect the first concave surface to form a first curved cutting edge. A third concave surface is located to intersect the first concave surface to form a second curved cutting edge and is located to intersect the second concave surface to form a third curved cutting edge. Each curved cutting edge extends from the base to the sharp distal point. A tissue cutting device is coaxial with the probe.
