Publication number: 20170100203Abstract: 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.Type: ApplicationFiled: December 16, 2016Publication date: April 13, 2017Inventors: Steven E. Field, Ryan L. Goosen, Brian R. Mulder, Richard M. Chesbrough

Patent number: 9579159Abstract: 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.Type: GrantFiled: November 5, 2013Date of Patent: February 28, 2017Assignees: Bard Peripheral Vascular, Inc., Bard Shannon LimitedInventors: Richard M. Chesbrough, Steven E. Field, Ryan L. Goosen, Jeffery W. Zerfas, Richard E. Davis

Publication number: 20160199150Abstract: A marking apparatus includes a rigid cannula having a peripheral wall forming a lumen that carries an imaging marker, a proximal end coupled to a handle, a lateral opening in the peripheral wall that is open to the lumen, and a closed-off distal portion having a ramp adjacent the lumen. The closed-off distal portion extends distally from the ramp to terminate at a tissue piercing pointed tip. The ramp of the rigid cannula is curved to transition from the peripheral wall of the rigid cannula to the lateral opening of the rigid cannula. The ramp of the rigid cannula is adapted to engage the distal end of the stylet as the stylet is advanced through the lumen of the rigid cannula to guide the distal end of the stylet to a position to substantially close off the lateral opening of the rigid cannula having the tissue piercing tip.Type: ApplicationFiled: March 23, 2016Publication date: July 14, 2016Inventors: Steven E, Field, Ryan L.

Publication number: 20150164610Abstract: 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.Type: ApplicationFiled: February 26, 2015Publication date: June 18, 2015Inventors: Steven E.

Publication number: 20150051486Abstract: 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.Type: ApplicationFiled: October 31, 2014Publication date: February 19, 2015Inventors: Richard M.
