Publication number: 20240138822Abstract: A biopsy device for percutaneous tissue removal includes an elongated housing having an operational axis, a stylet hub slidably mounted in the housing, where the stylet hub is movable relative to the housing between a proximal, armed position, and a distal, fired position, the stylet hub having a stylet strike, a cannula hub slidably mounted in the housing alongside the stylet hub, and a spring-biased arming member. The cannula hub is movable relative to the housing between a proximal, armed position, and a distal, fired position. The arming member is moveably mounted to the housing proximal of the respective stylet and cannula hubs, and configured for manually-actuated movement from a relaxed, extended position to a loaded, compressed position to define a compressive arming stroke. The biopsy device also includes an arming member biasing spring that restores the arming member from the compressed position to the extended position.Type: ApplicationFiled: October 31, 2023Publication date: May 2, 2024Applicant: HOLOGIC, INC.Inventors: Zachary Stephen Swick, Rosario Friedman, Brett Haarala, David Sauvageau, Donna Schulz Torres

Patent number: 9713694Abstract: A medical catheter assembly includes a catheter hub, an elongate catheter member extending from the catheter hub and having at least one longitudinal lumen for passage of fluids, an extension tube extending from the catheter hub and defining an internal lumen in fluid communication with the at least one longitudinal lumen of the catheter member and a clamp positionable about the extension tube. The catheter hub defines a reduced profile to facilitate passage of the catheter hub through a surgical tunnel. The clamp includes first and second clamp sections and defines a longitudinal clamp axis. The clamp has a longitudinal opening for passage of the extension tube and a movable member adapted to move from a first position to a second position to substantially close the internal lumen. The first and second clamp sections are separable to facilitate transverse positioning of the clamp sections about the extension tube.Type: GrantFiled: April 2, 2013Date of Patent: July 25, 2017Assignee: Covidien LPInventors: Richard Braga, Robert Frechette, Brett Haarala
