  • Publication number: 20200046349
    Abstract: A method for suture lacing includes providing a suture with a needle attached thereto, inserting the needle and suture into an organ through a passageway, throwing a single stitch through a first tissue member, throwing a single stitch through an opposed and spaced apart second tissue member, repeating the preceding step at least once, bringing the first and second tissue members in contact by tensioning the suture, whereby suture drag is minimized during the tensioning and even tissue compression substantially achieved, and securing the suture.

  • Patent number: 10524815
    Abstract: An ultrasonic forceps comprises a housing, an acoustic assembly, and a tine. The housing joins the acoustic assembly and the tine to the forceps and permits the tine to pivot relative to the acoustic assembly. The acoustic assembly comprises a transducer, a waveguide, and ultrasonic blade, and a waveguide sheath. The transducer is configured to generate ultrasonic vibrations directing the ultrasonic vibrations to the waveguide. The waveguide communicates the ultrasonic vibrations distally to the ultrasonic blade. The ultrasonic blade is configured to vibrate in response to the ultrasonic vibrations generated by the transducer. When the tine is pivoted relative to the transducer, the tine is configured to move toward the ultrasonic blade. Tissue may be grasped between the tine and the ultrasonic blade. The tissue may be denatured when the ultrasonic vibrations generated by the transducer vibrate the ultrasonic blade, thus resulting in the tissue being cut and/or sealed.

  • Patent number: 10426507
    Abstract: A surgical instrument including a transducer and an end effector is disclosed. The transducer may be configured to generate an acoustic standing wave of vibratory motion along a longitudinal axis and may include a piezoelectric stack positioned along the longitudinal axis. A length of the transducer may be less than ½ of the wavelength of the acoustic standing wave. The end effector may be acoustically coupled to and may extend distally from the transducer along the longitudinal axis. A sum of the length of the transducer and a length of the end effector may be an integer multiple of ½ of the wavelength of the acoustic standing wave.

  • Patent number: 10383754
    Abstract: Methods and devices create an intestinal braking effect, are non-invasive or minimally invasive, and may be reversible. These methods and devices are accomplished via stabilized implantable systems, and ingestible pills. In one embodiment, the implantable system comprises a device delivering a therapeutic substance to a target location within the gastrointestinal tract of a patient in order to initiate an intestinal braking effect which would promote sensations of satiety and stimulate excess weight loss for the patient.

  • Publication number: 20190239883
    Abstract: A surgical stapler includes an anvil half having an anvil channel member and a cartridge half having a cartridge channel member. A latching lever is coupled to the cartridge channel member and is pivotable between a closed position in which the lever fixes the anvil channel member relative to the cartridge channel member, and an open position in which the lever permits relative movement between the channel members. A locking member coupled to a proximal portion of the cartridge half is movable between a locked position when the lever is in the closed position and an unlocked position when the lever is in the open position. In the locked position the locking member captures the projection and locks the anvil half proximal portion to the cartridge half proximal portion. In the unlocked position the locking member releases the projection and permits separation of the proximal portions.

  • Publication number: 20190239888
    Abstract: An end effector for a surgical clip applier includes a body having a proximal end and a distal end, a clip cartridge coupled to the body and containing one or more surgical clips, and a head rotatably coupled to the distal end. First and second jaw members are mounted to the head such that rotation of the head correspondingly moves the first and second jaw members. The head is rotatable between a loading position, where the first and second jaw members are aligned to receive a distal-most surgical clip of the one or more surgical clips, and a clamping position, where the first and second jaw members are positioned to crimp a surgical clip interposing the first and second jaw members.

  • Publication number: 20190239885
    Abstract: A surgical stapler includes an anvil channel member, an anvil surface, and a cartridge channel member that releasably couples with the anvil channel member and includes a distal portion that receives a staple cartridge. The stapler further includes first and second latch features. The second latch feature moves between an open position and a closed position in which it engages the first latch feature and fixes the channel members together. A latch lockout member of the stapler is movable between a lockout state in which the lockout member locks the second latch feature in the open position, and a release state in which the lockout member permits the second latch feature to move to the closed position. The latch lockout member is configured to move from the lockout state to the release state in response to being engaged by the first latch feature.

  • Publication number: 20190239892
    Abstract: An end effector for a surgical clip applier includes an elongate body and a clip track provided within the body and containing one or more surgical clips. Each surgical clip includes a crown and a pair of legs extending longitudinally from the crown and diverging from each other at an obtuse opening angle. A pre-forming region is provided within the body and arranged to receive and deform the one or more surgical clips from a first state, where the pair of legs diverge at the obtuse opening angle, and a second state, where the obtuse opening angle is minimized. First and second jaw members are positioned at a distal end of the body and arranged to receive the one or more surgical clips from the pre-forming region in the second state.

  • Publication number: 20190239882
    Abstract: An apparatus includes a handle assembly, an end effector, a firing assembly, and a lockout assembly. The handle assembly includes first and second arms and a latching lever. The end effector includes first and second jaws and a staple cartridge. The firing assembly is configured to actuate from a pre-fired proximal position toward a distal position in order to staple and sever tissue captured between the first jaw and the second jaw. The lockout assembly is configured to prevent distal translation of the firing assembly in a locked configuration and allow distal translation of the firing assembly in an unlocked configuration. The latching lever is configured to actuate the lockout assembly from the locked configuration to the unlocked configuration in response to the latching lever pivoting the second jaw from a partially closed configuration to a fully closed configuration while the firing assembly is in the pre-fired proximal position.
