A surgical fastener applier including a housing containing a compartment, an elongated member extending distally from the housing, first and second jaws and a firing mechanism. The firing mechanism is movable between a first position and a second position to effect firing of fasteners into the tissue clamped between the first and second jaws. A power pack is removably loadable into the compartment, the power pack having a motor and an engagement member removably engageable with the firing mechanism within the compartment when the power pack is loaded into the compartment to effect movement of the firing mechanism. An interchangeable battery pack is removably loadable into the power pack for powering the motor. Bearings restrict axial and radial movement of the firing and articulation assembly in the power pack.

An implantable prosthetic valve has an in situ formable support structure. The valve comprises a prosthetic valve, having a base and at least one flow occluder. A first flexible component is incapable of retaining the valve at a functional site in the arterial vasculature. The first component extends proximally of the base of the valve. A second flexible component is incapable of retaining the valve at a functional site in the arterial vasculature. The second component extends distally of the base of the valve. At least one rigidity component combines with at least one of the first and second flexible components to impart sufficient rigidity to the first or second components to retain the valve at the site.

A surgical tissue connector system for moving a first internal body tissue to a position away from a second internal body tissue and then holding the first internal body tissue in the position. Tissue connectors are secured to cords such that the length of cord between the tissue connectors can be easily adjusted in a laparoscopic work space.

Devices and methods for affixing reinforcing material to a fascial incision in an abdominal wall to reinforce and augment closures thereof. The device includes first and second arms, each having a proximal end and a distal end extending away from a housing with a length therebetween. The distal end of the first arm is spaced from the distal end of the second arm such that the first and second arms are engageable with reinforcing material on opposing sides of a fascial incision. One or more fixation elements are deployable from the distal end of at least one of the first and second arms to affix the reinforcing material on opposing sides of the fascial incision.

Techniques for mesh augmentation and prevention of incisional hernia, including systems and methods for affixing mesh to a fascial incision. A mesh strip can be integrated with one or more uni-directional fasteners. Each fastener can include an anchoring mechanism adapted for affixation to anterior abdominal wall fascia and a mating interface. An applicator can include tension arms adapted to interface with the mating interfaces of the fasteners to maintain a vertical tension of the mesh strip and a handle coupled with the tension arms adapted to spread the tension arms and thereby control a horizontal tension of the mesh strip. The mesh strip can be configured to be aligned over a fascial incision using the applicator and affixed under tension to anterior abdominal wall fascia by tissue penetration of the anchoring mechanisms of the one or more fasteners.

Embodiments related to surgical anchors are described. In some embodiments, a surgical anchor may include a selectively removable blocker which may prevent one or more barbs of the surgical anchor from engaging with adjacent tissue until the selectively removable blocker is removed.

A mitral valve leaflet repair system may include a delivery catheter having at least one lumen extending proximally from a distal end of the delivery catheter, a plurality of anchor elements disposed within the at least one lumen, each of the plurality of anchor elements being configured to extend through one layer of mitral valve leaflet tissue, and a securing element configured to secure at least two of the plurality of anchor elements together on one side of the mitral valve leaflet tissue. The at least one lumen may include a suction lumen configured to grasp a mitral valve leaflet prior to extending the plurality of anchor elements through one layer of mitral valve leaflet tissue.

A surgical device includes a cartridge alignment mechanism that loads a cartridge onto an engagement portion without having to place the cartridge in proper orientation with the engagement portion.

A device for treating a left atrial appendage, including an implant having a contact member configured to engage an inside tissue surface of the left atrial appendage and configured to rotate in at least a first direction from a first position to at least a second position so as to twist the left atrial appendage when the contact member is engaged with an inside tissue surface of the left atrial appendage. Some embodiments can also include a securing element configured to move between a first position in which the securing element is decoupled from the contact member and a second position in which the securing element is coupled with the contact member.

Methods are described for use with a valve of a heart of a subject, the valve having an annulus, a first leaflet and an opposing leaflet, the heart having an atrium upstream of the valve, and a ventricle downstream of the valve. A tissue anchor, and an implant that includes a flexible frame, are transluminally advanced to the atrium. The implant is deployed within the atrium. Via anchoring of the tissue anchor to the annulus of the valve, the implant is secured within the heart by a first part of the frame being secured to the annulus, such that the frame extends over the first leaflet toward the opposing leaflet with a first side of the frame facing the first leaflet. Part of the frame can be disposed between the first leaflet and the opposing leaflet. Other embodiments are also described.
