  • Patent number: 12357306
    Abstract: A computer-assisted device include an actuator and one or more processors. The computer-assisted device is configured to support an instrument having an end effector located at a distal end. To perform an operation with the instrument, the one or more processors are configured to operate the end effector according to a state machine having a first state and a second state. In the first state a velocity set point of the actuator is set to a first velocity. In the second state the velocity set point of the actuator is set to a second velocity lower than the first velocity. The state machine transitions from the first state to the second state when a force or torque applied by the actuator is above a first threshold and transitions from the second state to the first state when the force or torque applied by the actuator is below a second threshold.

    Abstract: A forceps having an outer tube extending from a proximal portion to a distal portion and defining a longitudinal axis. A reciprocating inner tube can be located within the outer tube and extend along the longitudinal axis. A stationary jaw can be coupled to the distal portion of the outer tube and a moving jaw can be pivotably moveable relative to the stationary jaw. The moving jaw can be engaged with a portion of the reciprocating inner tube such that translation of the reciprocating inner tube pivots the moving jaw relative to the stationary jaw between an open and closed position.

  • Patent number: 11957853
    Abstract: Various embodiments disclosed relate to drug-coated balloon catheters for treating, preventing, or reducing the recurrence of a stricture and/or cancer, or for treating benign prostatic hyperplasia (BPH), in a non-vascular body lumen and methods of using the same. A drug-coated balloon catheter for delivering a therapeutic agent to a target site of a body lumen stricture includes an elongated balloon having a main diameter. The balloon catheter includes a coating layer overlying an exterior surface of the balloon. The coating layer includes one or more water-soluble additives and an initial drug load of a therapeutic agent. In some embodiments, the balloon catheter includes a length-control mechanism which stretches and elongates the balloon when it is in a deflated state, giving the balloon a smaller cross-sectional deflated profile for tracking through the body lumen and for removal after treatment.

  • Patent number: 11896289
    Abstract: A surgical instrument includes an end effector, a handle assembly, and a latch assembly. The end effector includes a first jaw, a second jaw pivotably coupled with the first jaw, a knife, and an electrode assembly. The handle assembly includes a housing associated with the first jaw, and an arm associated with the second jaw. The arm can pivot the second jaw between an open position and a closed position. The latch assembly can transition between an unlatched configuration and a latched configuration. The latch assembly can prevent the arm from pivoting the second jaw from the closed position toward the open position in the latched configuration. The latch assembly can allow the arm to pivot the second jaw from the closed position toward the open position in the unlatched configuration.

    Abstract: A surgical instrument includes an end effector, a handle assembly, and an electrode activation assembly. The end effector includes a first jaw, a second jaw, a knife, and an electrode assembly. The handle assembly includes a housing, and an arm. The arm can pivot the second jaw between the open position and the closed position. The arm can pivot relative to the housing between a first position, a second position, and a third position. The electrode activation assembly includes an activation button associated with the handle assembly, a resilient body, and a detent associated with either the housing or the arm. The activation button can activate the electrode assembly in response to the arm pivoting to the third position. The resilient body includes a first cam feature. The detent can engage the first cam feature as the arm pivots between the first position and the second position.

  • Patent number: 11896215
    Abstract: An Achilles tendon repair device comprises a handle for physician gripping and base having a first set of tendon rods disposed in an arcuate or U-shaped pattern about the base to engage the posterior surface of the tendon and impart a contour, or drape, the tendon in the posterior-anterior plane to increase the surface area for suturing. A second set of suture guide rods extend from the sides of the base and are spaced apart to allow insertion of suture needles along the entire length of the suture guide rods, and at any angle. A suture needle housing guide can be slidingly attached to the suture guide rods and includes sidewalls with predefined suture holes/angles. An adjustable clamping arm can engage the tendon's posterior surface such that the device grasps the tendon on both the anterior and posterior tendon surfaces simultaneously, while increasing posterior-anterior plane surface area to facilitate suturing.

  • Patent number: 11864821
    Abstract: A surgical instrument includes an end effector, a handle assembly, a knife drive assembly, and a lockout assembly. The end effector includes a pair of jaws, a knife, and an RF electrode. The handle assembly includes a housing associated with the first jaw, and an arm associated with the second jaw. The arm is pivotably coupled with the housing and pivots the second jaw between the open position and the closed position. The knife drive assembly includes a trigger slidably coupled with the housing, an actuating assembly, and a return assembly. The actuation assembly converts proximal translation of the trigger into distal actuation of the knife. The return assembly automatically actuates the knife from the fired position to the pre-fired position in response to the trigger reaching a predetermined proximal position. The lockout assembly prevents activation of the electrode and distal actuation of the knife while in the locked configuration.
