A full core biopsy device includes a needle assembly having stylet, spoon, and at least one coring cannula. A window is located in at least one of the spoon and coring cannula. An excising finger is configured to prolapse through the window into a lumen of the inner spoon or cannula to sever a tissue sample upon translation or axial advancement of the excising finger.

An apparatus for implanting a localization wire, wherein the apparatus exhibits a ready configuration and a relaxed configuration, includes a handle having a slot and a cannula disposed within the handle and having an insertion tip and a projection configured to selectively enter the slot. The cannula is movable between a ready configuration and a relaxed configuration. A localization wire is disposed within the cannula. An actuator is configured to retract the cannula into the handle.

Apparatus for implanting a preloaded localization wire

A method of operating a marking device includes defining an initial condition wherein a cannula is in an extended position and a stylet is in a ready position in the extended cannula, and, starting from the initial condition with the cannula in the extended position, sequentially: effecting movement of the stylet from a ready position to an implant position, ejecting an imaging marker through a distal opening in a cannula distal end of the cannula, and then; effecting a simultaneous unitary retraction of the cannula and stylet after ejection of the imaging marker from the distal opening in the cannula distal end.

Marking device with retractable cannula

A method of operating a tissue marking apparatus includes providing a tissue marking apparatus having a cannula, a stylet, and an imaging marker, the cannula having a peripheral wall forming a lumen and a lateral opening in the peripheral wall that is open to the lumen, and having a resilient end wall extending downwardly from the peripheral wall at a distal extent of the lateral opening, the stylet being slidably received within the lumen of the cannula for movement in the lumen; moving the stylet in a distal direction to expel the imaging marker from the lateral opening; and continue moving the stylet in the distal direction to deflect the resilient end wall of the cannula such that a distal end of the stylet passes beneath the resilient end wall to substantially close off the lateral opening of the cannula.

Self-contained, self-piercing, side-expelling marking apparatus

A biopsy marking apparatus for placing a radiopaque marker at the location of a percutaneous biopsy. The biopsy marking apparatus comprises an introducer in combination with a radiopaque marker. The introducer ejects the radiopaque marker at the location of the biopsy. The introducer is configured to completely eject the radiopaque marker and prevent it from being subsequently drawn into the introducer as the introducer is removed from the biopsied tissue mass. The radiopaque marker has enhanced radiopaque characteristics and enhanced non-migration characteristics.

Apparatus for the percutaneous marking of a lesion

A marking device according to one embodiment of the invention comprises a handle, a cannula having a cannula distal end and slidably mounted to the handle, and a stylet having a stylet distal end and slidably mounted to the handle in the cannula. The stylet distal end is spaced proximally of the cannula distal end to form a marker recess that receives an imaging marker. The marking device further comprises an actuator operably coupled to the cannula to effect retraction of the cannula into the handle following implantation of the imaging marker. The imaging marker can be implanted by advancing the stylet relative to the cannula to eject the imaging marker from the marker recess, or the cannula can be retracted relative to the stylet to expose the imaging marker.

A marking device includes a handle defining a hollow interior, and a delivery assembly slidably mounted to the handle. The delivery assembly includes a cannula, a stylet assembly, an imaging marker, and an actuator. The cannula has a cannula distal end with a marker recess. The imaging marker is disposed within the marker recess. The actuator is operably coupled to the delivery assembly and is operable to transition the delivery assembly through at least three configurations: a first configuration characterized in that the cannula is positioned in an extended position and the stylet assembly is positioned in a ready position; a second configuration characterized in that the cannula is positioned in the extended position and the stylet assembly is positioned in an implant position; and a third configuration characterized in that the cannula is positioned in the retracted cannula position and the stylet is retracted into the handle.

A marking apparatus includes a rigid cannula having a peripheral wall forming a lumen that carries an imaging marker. A lateral opening in the peripheral wall is open to the lumen. The lateral opening has a proximal extent and a distal extent. A closed-off distal portion is distal to the lateral opening. A resilient end wall extends downwardly from the peripheral wall at the distal extent of the lateral opening. A stylet has a distal end having a ramp. The stylet is slidably received within the lumen of the rigid cannula for movement in the lumen. The resilient end wall of the rigid cannula is configured to engage the ramp of the distal end of the stylet when the stylet is advanced through the lumen of the rigid cannula to an extended position to substantially close off the lateral opening of the rigid cannula.

An apparatus for percutaneously implanting a localization wire into a tissue mass includes a handle having a grip portion and a base. The grip portion is slidably mounted to the base. The base has a keyway. A cannula is movable relative to the handle between an insertion position and a retracted position. A localization wire is positioned to extend from the handle and into the cannula lumen. An actuator is coupled to the cannula and is configured to operate between a charged condition and a discharged condition to retract the cannula. A collar is mounted to the cannula. The collar includes a key having a key projection. The key projection is not aligned with the keyway when the actuator is in the charged condition and the key projection is aligned with the keyway to facilitate retraction of the cannula toward the retracted position to effect the discharged condition.

A sports board rack system includes an upper support frame, an upper pulley arrangement carried by the upper support frame, a lower support frame, and a lower pulley arrangement carried by the lower support frame. A flexible rack assembly is coupled between the upper and lower support frames and includes a pair of spaced apart rack units. Each rack unit includes spaced apart board supports. The upper and lower pulley arrangements are coupled together so that the flexible rack assembly is moveable between an expanded position and a retracted position. In the expanded position the board supports are aligned with one another in a horizontal direction for placement and removal of sports boards. In the retracted position the board supports are moved closer to one another so that a separation distance between adjacent board supports in a vertical direction is reduced.

Retractable sport board rack system

An apparatus for percutaneously implanting a localization wire into a tissue mass comprises a cannula with a preloaded localization wire having a distal end and at least one anchor. An actuator is in operable communication with the cannula and is configured for operation between a charged condition and a discharged condition to retract the cannula toward a retracted position to expose the distal end and the at least one anchor of the localization wire to the tissue mass, without inducing movement of the localization wire, and with the cannula being removable from the localization wire in its entirety.

A localizing wire includes an anchor portion that can change shape from a collapsed shape to an expanded shape and thereby anchor within a tissue mass. The localizing wire has an exterior portion that can lie flat against the tissue mass. The localizing wire can be repositioned or withdrawn without the need for the reinsertion of an introducer.

Removable localizing wire

The invention provides a device for percutaneously implanting an imaging marker for identifying a location within a tissue mass. The subcutaneous imaging marker comprises at least a first element and a second element, each of which have a primary imaging mode. The primary imaging mode of the first element is different from that of the second element.
