Disclosed are embodiments of a device for occluding a left atrial appendage (LAA) and other cavities or openings within a body. Some embodiments of the device can include an implant configured to be deployed within the LAA or other cavity, configured to be expanded or moved against a wall portion of the LAA or other cavity, and configured to twist at least a portion of the LAA or other cavity when the implant is rotated. Thereafter, one or more securing elements, staples, sutures, or other fasteners can be implanted in the gathered tissue to hold the tissue in the gathered state, thereby occluding the opening of the LAA or other cavity. In some embodiments, the opening of the LAA or other cavity can be occluded by elongating or otherwise reshaping the opening using an implant device, and securing the opening in the occluded state.

An anastomotic coupler is provided. A ring can include a plurality of receiving portions. A fixation device includes a cartridge. The cartridge includes a plurality of fasteners. The ring is aligned with the cartridge such that the receiving portions are aligned with the fasteners. Upon actuation of the fixation device, the fasteners puncture the tubular structure and are received by the receiving portions such that the tubular structure is coupled with the ring.

A staple for attaching a sheet-like implant to tissue or bone may include first and second arms, and first and second flukes. In some embodiments, the first arm has a proximal end and a distal end, and the second arm has a proximal end and a distal end. A bridge extends from the proximal end of the first arm to the proximal end of the second arm. The first fluke has a proximal end abutting the distal end of the first arm, and the first fluke extends distally from the first arm. The first fluke has a lateral extent larger than a lateral extent of the first arm and is mounted eccentrically thereto. The first fluke includes a proximal surface projecting at an outward angle in a proximal direction away from the distal end of the first arm to engage the tissue or bone when inserted therein. The second fluke has similar features. This arrangement causes the first and second flukes to rotate in response to a pullout force on the bridge. Methods for attaching a sheet-like implant to a target tissue are also disclosed.

A device for closure of an atrial septal defect (ASD) by deploying a pericardial patch includes a head including a distal jaw and a proximal jaw, and a distal disc attached to the distal jaw and a proximal disc attached to the proximal jaw. Each of the distal jaw and the proximal jaw includes at least one arm which closes when the distal disc moves forward and the proximal disc moves backward. Based on an engagement status of a distal engagement portion located on the at least one arm of the distal jaw with a proximal engagement portion located on the at least one arm of the proximal jaw, the pericardial patch deploys to close the ASD.

An anastomotic coupler is provided. A ring can include a receiving portion. A fixation device includes a cartridge. The cartridge includes a plurality of fasteners. Upon actuation of the fixation device, the fasteners puncture the tubular structure. The fasteners are received by the receiving portions such that the tubular structure is coupled with the ring.

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.

A tissue thickness compensator can comprise a compensator body and at least one vessel contained in the compensator body. The vessel can define an inner cavity which can comprise an inner atmosphere having a pressure which is lower than the atmospheric pressure of the atmosphere surrounding the tissue thickness compensator. In at least one embodiment, the vessel and the compensator body can be maintained in a collapsed state until staples are fired through the vessel. At such point, the vessel can re-expand and apply a biasing force to tissue captured within the staples.

A device for attaching a sheet-like implant to a target tissue includes a pilot member and a staple push rod. In some embodiments, the pilot member has a distal end and at least a pair of prongs extending from the distal end. The prongs are configured to form pilot holes when the distal end of the pilot member is pressed against the target tissue. The staple push rod is disposed within at least a portion of the pilot member and slidable relative thereto. The staple push rod includes at least a pair of stakes. Each stake is dimensioned to engage a surface of a staple to apply pushing forces thereto. Each stake is positioned relative to a prong along an inner surface of the pilot member so that the stakes advance into the pilot holes when the stakes are moved in a distal direction. Methods for attaching a sheet-like implant to a target tissue are also disclosed.

A surgical implant comprising a receiver member and deployment member for clamping and sealing tissue of variable thickness, a corresponding applicator tool and surgical system for connecting, sealing, fastening and/or attaching tissue to itself, to other tissue and/or to non-tissue structures, and/or sealing the flow of fluid at and/or between structures such as tissue and vessel structures.

Devices, systems and/or methods for repairing soft tissue adjacent a soft tissue repair site. In one embodiment, the repair device includes an anchor member having a base with at least four legs extending from the base. The base extends with a generally flat circular profile defining an upper surface and an underside surface with a central opening extending therethrough. Further, the at least four legs extend from the base with an elongated angled portion, the elongated angled portion being oriented at an angle less than seventy-five degrees relative to the underside surface of the base. With this arrangement, the anchor member may be fixated to soft tissue by rotating the base with a delivery tool so that the elongated angled portion of the at least four legs facilitates the anchor member sinking into the soft tissue and fixating thereto.
