Patent number: 11864829Abstract: A handle for longitudinal movement of a first tubular member over a second tubular member includes a handle body, a nose cone, a locking mechanism, and a retraction control. The nose cone has a sleeve and an outer wall that define a control channel therebetween. The nose cone is moveable over the handle body between extended and retracted positions. The locking mechanism has locked and unlocked positions for selectively fixing the nose cone in the extended and retracted positions. A finger of the retraction control is positioned within the control channel of the nose cone. The retraction control has first and second positions relative to the nose cone for transitioning the locking mechanism between the locked and unlocked position and for moving the nose cone between the extended and retracted positions.Type: GrantFiled: April 11, 2022Date of Patent: January 9, 2024Assignee: Covidien LPInventors: William J. Dickhans, Carol L Shaffer, Alex A. Peterson, Arlen J. Reschke

Patent number: 11559290Abstract: Methods, systems, and devices for accessing tissue outside a bronchus and marking the location of a biopsy are provided. The method includes loading a navigation plan into a navigation system with the navigation plan including a CT volume generated from a plurality of CT images, inserting an extended working channel (EWC) including a location sensor into a patient's airways, registering a sensed location of the EWC with the CT volume of the navigation plan, and selecting a target in the navigation plan located outside the periphery of a patient's airways. The method further includes navigating the EWC and location sensor proximate the target, inserting a piercing catheter into the EWC, piercing through an airway wall to reach the target, storing a position of the location sensor in the navigation system as a biopsy location, and performing a biopsy at the stored biopsy location.Type: GrantFiled: February 7, 2020Date of Patent: January 24, 2023Assignee: Covidien LPInventors: Katherine A. Herdina, Carol L. Shaffer

Patent number: 10814128Abstract: A catheter includes first and second handles, first and second tubular members, and first and second electrodes. The first tubular member defines a channel therethrough and is coupled to and distally extends from the first handle. The second tubular member is coupled to and distally extends from the second handle. The second tubular member is slidably disposed within the channel of the first tubular member and defines a lumen therethrough. The first and second electrodes are configured to generate an electric field therebetween. The second handle is translatable relative to the first handle between a retracted position in which the second electrode is adjacent the first electrode and an extended position in which the second electrode is spaced apart from the first electrode.Type: GrantFiled: October 19, 2017Date of Patent: October 27, 2020Assignee: COVIDIEN LPInventors: Tyler J. Eckwright, Katherine A. Herdina, Carol L. Shaffer

Patent number: 10582914Abstract: A bronchial piercing catheter assembly used to navigate to target tissue in a patient under EMN guidance includes a handle, a shaft, and a catheter tip. The shaft extends from the handle and includes a proximal end and a distal end. The catheter tip is located on the distal end of the shaft and is designed to penetrate tissue. The catheter tip further includes a base member defined along a central longitudinal axis of the bronchial piercing catheter and a trailing tip member adjacent to the base member. The trailing tip member tapers relative to the base member and a leading tip member adjacent to the trailing tip member. The leading tip member further tapers to a distal end.Type: GrantFiled: January 6, 2017Date of Patent: March 10, 2020Assignee: COVIDIEN LPInventors: Katherine A. Herdina, Carol L. Shaffer
