  • Patent number: 11278370
    Abstract: 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.

  • Patent number: 10463446
    Abstract: 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.

  • Patent number: 10357328
    Abstract: 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.

  • Patent number: 10342635
    Abstract: 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.

  • Publication number: 20170119492
    Abstract: A method for safely operating a marking apparatus includes: providing a handle, a cannula that extends from the handle, a stylet slidably received within a lumen of the cannula for movement between a ready position and an extended position, and a plunger coupled to the stylet; providing a safety that comprises a channel provided on one of the handle and the plunger and a catch provided on the other of the handle and the plunger; defining a safety-on position wherein the catch and the channel are rotationally misaligned; defining a safety-off position wherein the catch and the channel are rotationally aligned; and rotating the catch with respect to the channel to move the safety from the safety-on position to the safety-off position to permit movement of the plunger and the stylet from the ready position to the extended position to expel the imaging marker from the cannula.
