  • Patent number: 11564689
    Abstract: The present disclosure relates to a fastener applicator including a handle, a first trigger coupled rotatably with respect to the handle, and a second trigger coupled rotatably with respect to the handle. An interlock is disposed with the second trigger and comprises a cam follower engaged in a cam channel that selectively prevents rotation of the second trigger relative to the first trigger depending on a location of the cam follower within the cam channel. The location of the cam follower in the cam channel is set by a position of the first trigger. Methods of operating the various embodiments disclosed are also provided.

  • Publication number: 20220287713
    Abstract: Apparatus, systems, and methods are described for closing the base of a left atrial appendage or other tissue structure. A tissue closure device comprises a pair of legs having compliant surfaces for engaging against opposite sides of the tissue structure. A plurality of axially spaced-apart tissue-penetrating fasteners are delivered from one leg to the other to pierce the intervening tissue and hold the closure device in place on the tissue structure.

  • Publication number: 20190298381
    Abstract: A surgical applicator for a fastener, the surgical applicator comprising: a handle; a trigger movable relative to the handle between an initial position, an actuated position, and an intermediate position between the initial position and the actuated position; and a lockout mechanism movable relative to the trigger between a locked position and an unlocked position, the lockout mechanism operatively arranged to: lock the trigger in the intermediate position when the trigger is moved from the initial position toward the actuated position; and permit movement of the trigger from the intermediate position toward the initial position or the actuated position when the lockout mechanism is moved from the locked position to the unlocked position.

  • Patent number: 10349935
    Abstract: Devices, systems, and methods for closing the base of a left atrial appendage or other tissue structure comprise a device applicator having jaws, a shaft, and a handle. First and second triggers on a handle are configured to close the jaws and a closure device in a step-wise manner where tissue penetrating fasteners within the closure device are engaged by studs on the jaws, where the studs must be released prior to the opening of the jaws.

  • Publication number: 20190151608
    Abstract: An implantable occlusion and tissue ingrowth resistant fluid interface is provided with a housing, an orifice and a catheter port. The housing is formed from at least one biocompatible material and is configured without sharp edges or corners. The housing at least partially defines an internal housing cavity. The orifice member at least partially defines an orifice between the internal housing cavity and an exterior of the housing. The orifice has an elongated transverse cross-section configured with a length that is at least four times its maximum width. The catheter port is located on the housing and is configured to couple with a catheter such that the internal housing cavity is in fluid communication with a lumen of the catheter when the catheter is coupled to the catheter port. Embodiments having a moving cylinder, a rotor, and non-chemical surface modifications, as well as methods of use are also disclosed.

  • Patent number: 10285836
    Abstract: The present application describes an implant system useable for positioning an implant device such as a device useful for restricting passage of ingested food into the stomach. In one embodiment, the disclosed system includes a plurality of anchors that may be coupled to tissue within the stomach, or to a tissue tunnel formed by plicating stomach wall tissue. The anchor includes a loop. During use, the implant device is inserted through the loop and expanded such that it retains its position within the loop until removed. Instruments for implanting and explanting the implant device are also described.
