A surgical instrument system includes a surgical fastener applier and a positioning guide. The positioning guide includes an implant guide. The implant guide defines a guide channel configured to receive a portion of an implant to support the implant relative to the end effector to enable the surgical fastener applier to fire one or more fasteners through the implant for securing the implant to tissue.

A surgical device is provided and includes a handle housing, an endoscopic assembly, and a follower assembly. The endoscopic assembly extends distally from the handle housing and includes an inner tube defining a longitudinal axis. The inner tube includes a distal portion defining a pair of opposed tines. The endoscopic assembly is configured to support a plurality of anchors at least partially therein. The follower assembly is disposed at least partially within the inner tube at a location proximal of the plurality of anchors, and includes a head and a shaft. A portion of the head is disposed between the pair of opposed tines. Actuation of the endoscopic surgical device causes rotation of the inner tube about the longitudinal axis relative to the handle housing, and causes distal advancement of the follower assembly relative to the inner tube.

A surgical fastener applying device for releasable connection to an end effector is provided. The surgical fastener applying device includes an elongated body portion having an outer tube and an inner shaft assembly. The inner shaft assembly defines a non-circular bore in a distal end thereof. The inner shaft assembly is longitudinally movable through the outer tube. The outer tube and the inner shaft assembly define corresponding openings extending radially therethrough. The surgical fastener applying device includes a detent movable within the openings of the elongated body portion. The detent floats between the end effector and the elongated body portion to enable selective connection between the end effector and the elongated body portion.

An apparatus and method for joining members together using a self-drilling screw apparatus or stapling apparatus are disclosed. The screw apparatus includes a worm drive screw, a spur gear and superior and inferior screws which turn simultaneously in a bi-directional manner. A rotating mechanism drives the first and second screw members in opposite directions and causes the screw members to embed themselves in the members to be joined. The screw apparatus can be used to join members such as bones, portions of the spinal column, vertebral bodies, wood, building materials, metals, masonry, or plastics. A device employing two screws (two-in-one) can be combined with a capping horizontal mini-plate. A device employing three screws can be combined in enclosures (three-in-one). The stapling apparatus includes grip handles, transmission linkages, a drive rod a fulcrum and a cylinder. The staple has superior and inferior segments with serrated interfaces, a teethed unidirectional locking mechanism and four facet piercing elements. The staples can be also be used to join members such as bones, portions of the spinal column, or vertebral bodies.

Some of the present apparatuses include a flexible vascular graft defining a lumen and a hub having a distal end configured to penetrate a blood vessel, a proximal end, and a wall extending between the distal end and the proximal end that defines an interior passageway. In some apparatuses, the vascular graft is non-removably coupled to the hub, and the lumen of the vascular graft is in communication with the interior passageway of the hub. Some apparatuses include one or more helical protrusions fixed in relation to the wall and configured to secure the hub relative to the blood vessel, each of the one or more helical protrusions extending away from the interior passageway. In some apparatuses, the wall has an outer surface defining an annular recess that extends around the wall, the recess configured to receive at least a portion of a wall of the blood vessel.

A bi-directional fixating transvertebral (BDFT) screw/cage apparatus including an intervertebral cage for maintaining disc height, and a method of inserting the same is provided. The intervertebral cage includes a first internal screw guide and a second internal screw guide, a first screw member and a second screw member, and a central screw locking lever coupled to the intervertebral cage, wherein the central screw locking lever prevents the first screw member and the second screw from pulling-out of the first internal screw guide and the second internal screw guide. The central screw locking lever includes a rotatable handle and stem portion, or a screw locking horizontal bracket. A pliers device for inserting and removing the bi-directional fixating transvertebral (BDFT) screw/cage apparatus, a posterior cervical and lumbar facet joint staple, and a staple gun for a posterior cervical and lumbar facet joint staple also are provided.

A handle assembly for use with a surgical tack applier includes an actuation assembly and an articulation lever assembly configured to articulate an articulation portion of the surgical tack applier. The actuation assembly includes a motor, an actuation rod, and an actuation switch configured to actuate the motor. The actuation rod has a first end operatively coupled to an output shaft of the motor for concomitant rotation therewith, and a second end operatively coupled to a loading unit of the surgical tack applier such that rotation of the actuation rod ejects a surgical tack from the loading unit. The articulation lever assembly includes an articulation rod operatively coupled with an articulation portion of the surgical tack applier such that axial displacement of the articulation rod causes articulation of the articulation portion, and an articulation lever operatively coupled with the articulation rod.

A medical device includes an implant anchor comprising first and second opposing end portions. The implant anchor may also include a fixation element to configured to couple the implant anchor to an implant, and an anchor element configured to couple the implant anchor to bone. At least a portion of the implant anchor has a porous structure.

A total joint replacement system comprising a first and a second implant system. The first implant system includes a first implant having a first load bearing surface based on a first removed portion of an articular surface of a patient's first bone, and a first anchor having a first threaded region configured to be secured into the first bone, wherein the first anchor is configured to be secured to the first implant. The second implant system includes a second implant having a second load bearing surface based on a second removed portion of an articular surface of a patient's second bone, and a second anchor having a second threaded region configured to be secured into the second bone, wherein the second anchor is configured to be secured to the second implant.

A biodegradable scaffold for wound closure including a central rod and two spaced-apart plates. The central rod may have an engagement block on top for stabilizing an implanting tool. The two spaced-apart plates include an upper plate connected to the central rod and a lower plate connected to the central rod. Each of the upper and lower plates may include perforations which may be useful for detachably connecting an implanting tool and which encourage ingrowth of the tissue. The biodegradable scaffold allows tension free anatomic alignment of tissue within the plates and facilitates wound healing. The upper and lower plate may have a helical portion, in which each plate may extend around the central rod. The helical portion serves to draw or pull tissue around the wound defect into the scaffold in the course of deploying the scaffold.
