  • Patent number: 9060779
    Abstract: The present embodiments provide systems and methods for deploying at least one clip device. In a first embodiment, the system comprises a first clip device having first and second arms. The first clip device and an associated sliding ring are configured to be selectively advanced through a lumen of an inner catheter. Selective positioning of an outer catheter over a distal region of the inner catheter causes a distal region of the inner catheter to bow radially inward to form a constriction that securely engages the sliding ring of the first clip device, thereby allowing for partial closure and repositioning of the first clip device. In an alternative embodiment, a delivery system includes a single catheter having a tapered distal region, such that upon ejection of the sliding ring from the distal end of the catheter, the sliding ring is dimensioned to abut the distal end of the catheter. In any of the embodiments, multiple clips may be sequentially loaded and deployed using the delivery systems.

    Abstract: An instrument for clamping a surgical clip has a handle assembly, a shaft assembly, and an end effector. The handle assembly has a trigger and an articulation knob. The shaft assembly has an outer ground tube, a middle articulation tube, and a push/pull tube disposed within the middle articulation tube. The trigger is operable to cause longitudinal translation of the push/pull tube. The outer ground tube and the middle articulation tube present mating angled faces sloped in opposing directions. Rotation of the articulation knob causes rotation of the middle articulation tube. Rotation of the middle articulation tube changes the orientation of the angled faces and thus causes articulation of the middle articulation tube and the push/pull tube. The end effector has a pair of jaws configured to apply a surgical clip to a vessel. Longitudinal translation of the push/pull tube causes closure of the pair of jaws.

  • Patent number: 8945163
    Abstract: Methods and devices are provided for cutting and fastening tissue. In one embodiment, a surgical device can be used to at least partially transect a stomach by not cutting and/or not fastening a portion of tissue engaged in an end effector located at the device's distal end. A portion of the stomach can be engaged by the end effector, and the end effector can be actuated to cut and/or to apply one or more fasteners to tissue engaged in a distal portion of the end effector but not to cut and/or apply fasteners to tissue engaged in a proximal portion of the end effector. In a similar way, the surgical device can be used in any surgical procedure in which it is desired to cut and/or fasten a distal portion of tissue engaged by the end effector but not a proximal portion of tissue engaged by the end effector.

  • Patent number: 8945154
    Abstract: A tissue closing device includes an elongate arrangement device of which a distal end portion can penetrate an opening penetrating an living tissue membrane and which has a handling portion on the proximal side, and a clip which is detachably retained at a distal end portion of the arrangement device and which closes the opening. The arrangement device includes a retaining member for detachably retaining the clip and pulling the clip in the proximal direction, a cover tube, and a fixed tube. The handling portion has a first elastic member. When a restriction for maintaining the coil spring in a deformed state is canceled, the thread is moved to the proximal direction by the restoring force of the coil spring in the condition where the clip is locked to a distal end portion of the fixed tube, and the clip is pulled in the axial direction by the thread, whereby a deformation portion is deformed.

  • Publication number: 20150032132
    Abstract: Surgical methods for closing a gastrotomy. The surgical method for closing an opening in an organ wall comprises positioning a distal end portion of a steerable overtube adjacent a portion of the organ wall through which the opening extends. The surgical method further comprises inserting a flexible clip magazine into the steerable overtube. The surgical method comprises grasping tissue through which the opening extends and drawing a portion of the grasped tissue into a clamping position between upper and lower clip arms of a distal-most tissue apposition clip supported within a distal end of the clip magazine. The surgical method further comprises advancing the distal-most tissue apposition clip onto the portion of grasped tissue.

    Abstract: A device for clipping tissue includes a clip including first and second arms, a pusher member received over a proximal end of the clip, an outer sleeve distal of the pusher member and received over the first and second arms and being pushed distally over the clip by the pusher member from a first position in which the first and second arms are unconstrained by the outer sleeve in a tissue receiving configuration to a second position in which the first and second arms move to a closed tissue gripping configuration. A clip holder has first and second fingers which are held by the pusher member against corresponding cuts on a proximal end of the clip to couple the clip to the device. When the pusher member is moved distally to the second position, the first and second fingers move radially outward releasing the clip.

  • Patent number: 8926656
    Abstract: An apparatus for delivering a closure element into an opening formed in a blood vessel or other body lumen and methods for manufacturing and using same. The apparatus is configured to retain the closure element such that the closure element is disposed substantially within the apparatus. The apparatus also can engage, and position the closure element substantially adjacent to, the blood vessel wall adjacent to the opening. During deployment of the closure element, the apparatus expands the closure element beyond a natural cross-section of the closure element such that the closure element, when deployed, is configured to engage a significant amount of the blood vessel wall and/or tissue. Engaging the blood vessel wall and/or tissue, the closure element is further configured to return to the natural cross-section, thereby drawing the engaged blood vessel wall and/or tissue substantially closed and/or sealed, such that hemostasis within the opening is enhanced.

  • Patent number: 8920447
    Abstract: Intragastric implant devices for obesity treatment are disclosed. The device is passive and does not autonomously change shape, but instead reacts to movement of the stomach to induce satiety. The device includes a series of connected, articulated clips that plicate the stomach wall nondestructively (no puncturing through the gastric wall) such that the overall volume of the stomach is reduced. Cam-shaped clamping surfaces prevent slippage of the stomach tissue from within the clips. Methods of implant are disclosed including delivering the device through a transoral delivery tube and advancing the device through the esophagus to be deployed within the stomach. Removal of the device occurs in the reverse.
