    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： An intracorporeal marker delivery system includes a delivery device including a delivery cannula and a plunger. The delivery cannula has an inner lumen, a distal tip, and a discharge opening in communication with the inner lumen. A radiographically detectable marker having a fibrous-body and a radiographically detectable marker element coupled to the fibrous body is disposed within and pushable by the plunger through the inner lumen of the delivery cannula. An MRI detectable distal tip plug is disposed at least in part within a distal portion of the inner lumen distal to the radiographically detectable marker, and configured to partially occlude the discharge opening in the delivery cannula. An ultrasound detectable short term marker is interposed between the radiographically detectable marker and the MRI detectable distal tip plug in the inner lumen of the delivery cannula.

    摘要： A system for at least partially filling and marking a cavity within a patient includes a delivery device. A quantity of marker forming fluid is located within the delivery device. The quantity of marker forming fluid is configured to at least partially fill the cavity and form therein a bioabsorbable body after delivery into the cavity from the delivery device. A radiopaque marker, separate from the quantity of marker forming fluid and releasably attached to a portion of the delivery device, is configured to be delivered into the quantity of marker forming fluid in the cavity from the delivery device and configured to remain in the bioabsorbable body upon the formation of the bioabsorbable body in the cavity.

    摘要： The invention provides materials, devices and methods for marking biopsy sites for a limited time. The biopsy-marking materials are ultrasound-detectable bio-resorbable powders, with powder particles typically between about 20 microns and about 800 microns in maximum dimension, more preferably between about 300 microns and about 500 microns. The powders may be formed of polymeric materials containing cavities sized between about 10 microns and about 500 microns, and may also contain binding agents, anesthetic agents, hemostatic agents, and radiopaque markers. Devices for delivering the powders include tubes configured to contain the powders and to fit within a biopsy cannula, the powders being ejected by action of a syringe. Systems may include a tube containing powder, and a syringe containing sterile saline. The tube may be configured to fit within a biopsy cannula such as a Mammotome® or SenoCor 360™ cannula.
