Abstract: A surgical tensioner and methods for surgical repairs. A tensioning adapter can be removably attached to, and detached from, a handle and/or elongated shaft of a surgical instrument to allow a flexible strand (suture or wire) attached to tissue (for example, soft tissue, graft or bone segments) to be secured to it and tensioned. A tensioning adapter can include a securing mechanism that can capture a flexible strand and lock it into place. A tensioning adapter can include an adjustment device to adjust tension on the flexible strand.

Abstract: A surgical construct includes a loop configured to be anchored in a bone tunnel, a tail extending from the loop and configured to pull the loop into the bone tunnel, and a repair strand having a section received in the loop. The repair strand extends from the loop in a direction away from the tail and has a free end configured to engage a tissue. A method of tissue repair using the surgical construct involves pulling the loop into the bone tunnel with the tail, bunching the loop to anchor it in the bone tunnel, and engaging a tissue with the repair strand.

The body region has a substantially open mesh construction and at least a first elongate end region axially extending from and being one part with the body region having a substantially closed mesh construction. The width of the end region is substantially less than a width of the body region.

Abstract: An actuator for a surgical apparatus includes an elongated body extending along a longitudinal axis and an actuation structure. The actuation structure is operably coupled to the body and extends from a proximal end to a distal end. The actuation structure is configured to sequentially translate proximally and distally along the longitudinal axis.

Abstract: Methods for tissue repairs with mattress stitch are disclosed. A mattress stitch is created with a suture passer and a suturing construct using only one portal and without shuttling steps. The suture passer is provided with two sharp teeth or tines that pierce tissue (or tissue and associated graft) at two different locations. The suturing construct can be a loop terminating in a tail. The tail is passed from one tooth to another and then secured into a securing mechanism of one of the two sharp teeth. The tail is passed through the loop to form a cinch loop around and through the tissue (or the tissue and the graft).

Abstract: An anatomic simulacra includes at least one reinforced hole defined through the anatomic simulacra. The at least one reinforced hole includes a bore and a reinforcement area proximate the bore. A kit for performing a surgical training procedure includes the anatomic simulacra.

Abstract: A 3D printed anatomic simulacra includes an inner structure, an exterior shell surrounding the inner structure and the core, at least one fragmented exterior shell piece adjacent to the exterior shell, a removable matrix extending between the inner structure and the core, and support structures embedded within the removable matrix, the plurality of support structures extending throughout the inner structure. The removable matrix is configured to be removed from the 3D printed anatomic simulacra before a simulated medical procedure. Another 3D printed anatomic simulacra includes a flexible connective tissue connecting at least two components, the flexible connective tissue defining voids, wherein the plurality of voids are configured to sequentially tear under an applied load, thereby simulating a predefined tear classification. Another anatomic simulacra includes pretensioned fibral elements embedded within a matrix.

Abstract: Methods, systems and computer program products of constructing a transform that registers a two-dimensional (2D) image and a three-dimensional (3D) device depicted in the image. The methods include determining a best pitch, spin and x-y-z positions of a 3D mathematical device model as compared to the device depicted in a first obtained 2D image, determining a best x-y-z position of a focal point as compared to the device depicted in the first image, and, based thereon, constructing a transform that registers the first image and the device.

Abstract: A kit, system and method for a surgical training procedure that uses at least one polymer-based anatomic simulacra. In one example, the kit for a surgical training procedure includes at least one polymer-based anatomic simulacra that corresponds to a portion of an anatomy. The kit also includes at least one instrument configured to perform at least a portion of a surgical training procedure on the at least one polymer-based anatomic simulacra.

Abstract: Surgical anchor constructs, fixation devices, and methods for tissue repairs are disclosed. A soft suture anchor has a cannulated sheath (that is fixed in bone), at least one repair suture attached to the sheath, and at least one hybrid shuttling link attached to the sheath. The hybrid shuttling link is configured to act as both a shuttle/pull device and a repair suture. A free end of the repair suture is passed through the lumen and the body of the sheath to form at least one splice and a an adjustable, flexible, tensionable, knotless loop around soft tissue to be attached to bone. The hybrid shuttling link may form a knotted loop around soft tissue to be attached to bone.

Abstract: An electrode assembly for an electrosurgical ablator may include an insulator having a distal end portion and a proximal end portion. The insulator may include a rim forming a distal extent of the distal end portion and an aperture disposed in the distal end portion. An electrode is disposed in the aperture and forms a cavity having a profile shape recessed from the distal end portion toward the proximal end portion. The electrode assembly projects a focal point of an ablation region emitted from the supply electrode through the projecting rim to a projection distance beyond the distal extent.

Abstract: Expandable surgical anchors and methods of tissue repair with knotless fixation. The method includes coupling a repair strand to tissue to be fixated and inserting an implant with the repair strand that is captured by an implant into a pre-drilled bone hole in an insertion direction. After the implant is inserted into the bone hole, an expanding cannulated fixation device is installed into the bone hole such that the repair strand is positioned outside of the fixation device. After installing the fixation device into the bone hole, the fixation device is expanded by pulling the implant in an activation direction into the fixation device while the fixation device remains stationary, thereby compressing the fixation device against the bone hole with the repair strand disposed between an outer surface of the fixation device and the bone hole and providing tissue fixation without tying any knots.

Abstract: Exemplary microfracture pick systems may include a microfracture pick, a strike plate, and a punch extension. The strike plate may be secured to a handle of the microfracture pick, and the punch extension is connectable to the strike plate. The punch extension is configured to apply an “off-axis” impact force to the microfracture pick. The “off-axis” impact force is generally aligned with an axis of a strike tip of the microfracture pick, thereby substantially preventing the strike tip from skiving across a bone surface during surgical uses.

Abstract: A method for tracking patient features in a surgical field includes capturing an image stream in a field of view demonstrating patient features of a patient anatomy. A first feature set is identified in a tracking region of the field of view of the image stream. The relative motion among a first plurality of the image features in the first feature set is monitored in the image stream over time. Moving features from the first features set are filtered to generate a second feature set. The second feature set defines tracking features. The location and orientation of the patient anatomy is then tracked based on the feature locations of the plurality of tracking features.
