Patent number: 12048473Abstract: A surgical instrument includes an end effector assembly and a deployment mechanism for deploying a proximal hub associated with an energizable member between proximal and distal positions. The deployment mechanism includes a rotatable shaft, a cord including a proximal end engaged to the rotatable shaft and a distal end engaged to the proximal hub, a biasing member positioned to bias the proximal hub towards the distal position, and a gear assembly operably coupled to the rotatable shaft. The gear assembly is configured to move the proximal hub from the distal position to the proximal position against the bias of the biasing member by rotating the rotatable shaft relative to the cord to at least partially wind-up the cord about the rotatable shaft.Type: GrantFiled: November 27, 2019Date of Patent: July 30, 2024Assignee: Covidien LPInventor: Amarsinh D. Jadhav

Patent number: 12048475Abstract: A surgical instrument includes a first drive assembly, a second drive assembly, and a deployment mechanism. The first drive assembly is coupled to a first component and is configured to translate a first longitudinal distance X1 to deploy the first component. The second drive assembly is coupled to a second component and is configured to translate a second longitudinal distance X2 to deploy the second component. The deployment mechanism is operably coupled to both the first and second drive assemblies and is configured to move from a first position to a second position to translate the first and second drive assemblies the respective first and second longitudinal distances X1 and X2 to deploy the first and second components.Type: GrantFiled: August 24, 2020Date of Patent: July 30, 2024Assignee: Covidien LPInventor: Peter M. Mueller

Patent number: 12048476Abstract: A surgical instrument includes a housing and an elongated shaft operably coupled to an actuating mechanism moveable between an actuated position and an unactuated position. An end effector includes a pair of opposing first and second jaw members and is adapted to connect to a source of electrosurgical energy. A switch is moveable between an activated position to initiate delivery of electrosurgical energy to the end effector and a deactivated position to terminate delivery of electrosurgical energy to the end effector. A switch activation member is configured to move the switch between an activated position and a deactivated position. A switch control member is configured to maintain the switch in the activated position during at least partial movement of the actuating mechanism from the actuated position to the unactuated position.Type: GrantFiled: August 17, 2021Date of Patent: July 30, 2024Assignee: Covidien LPInventor: Tony Moua

Patent number: 12048480Abstract: A method and system for mapping tissue and producing lesions for the treatment of cardiac arrhythmias in a non-thermal and optimal manner, minimizing the amount of energy required to selectively stun or ablate the target tissues. Energy may be delivered only at the moment(s) of best device position and proximity of an electrode to target tissue, and only during a time in the cardiac cycle determined to be optimal for reversible or irreversible effects. A method may include determining timing of the cardiac cycle and an optimal time within the cardiac cycle for energy delivery, evaluating proximity between at least one energy delivery electrode and the target tissue, and delivering pulsed field energy from the at least one energy delivery electrode to the target tissue when, during the optimal time for energy delivery, the at least one energy delivery electrode is in close proximity with the target tissue.Type: GrantFiled: May 17, 2021Date of Patent: July 30, 2024Assignee: Medtronic Ablation Frontiers LLCInventors: Mark T. Stewart, Catherine R. Condie, Jay L. Kelley
