Abstract: A tendon/ligament repair implant for treatment of tears or lesions of tendons and ligaments, including capsular reconstruction, and compositions for delivering calcium and/or phosphate ions in combination with a collagen solution that can be placed between soft tissue and bone to facilitate healing of the soft tissue-bone interface are provided. The implant may incorporate features of rapid deployment and fixation by arthroscopic means that complement current procedures; tensile properties that result in desired sharing of anatomical load between the implant and native tendon during rehabilitation, or, in situations where the native tissue cannot be repaired tensile properties that provide for substitution of the native tissue selected porosity and longitudinal pathways for tissue in-growth; and may include an at least partially bioabsorbable construction to provide transfer of additional load to new tendon-like tissue and native tendon over time. The compositions can be pre-dried into a thin sheet of material and delivered as a pre-formed matrix, or as a gel or paste which sets in place to form the matrix between the soft tissue and bone.

Abstract: Patient-specific guides for the Latarjet procedure, as well as surgical systems and methods of performing the Latarjet procedure to treat glenohumeral instability using such patient-specific guides are disclosed. A patient-specific coracoid guide and a patient-specific glenoid guide may be configured based on preoperatively generated three-dimensional models of the patient's shoulder anatomy. Guides may be configured for coracoid graft preparation and glenoid decortication. The coracoid graft may be placed in the desired position based on three-dimensional (3D) preoperative planning.

Abstract: Embodiments of negative pressure wound therapy systems, apparatuses, and methods for operating the systems and apparatuses are disclosed. In some embodiments, the apparatus includes a negative pressure source, a connector port, at least one switch, and a controller. The negative pressure source is connected through the connector port to either (i) a wound dressing having a canister configured to store fluid aspirated from the wound or (ii) a wound dressing without a canister between the connector port and the wound dressing. The controller determines, based on a signal received from the at least one switch, whether the canister is positioned in the fluid flow path and adjusts one or more operational parameters of negative pressure wound therapy based on the determination. The switch is activated by the connection of either the canister or canisterless wound dressing to the apparatus.

Abstract: There are provided herein methods and products resulting therefrom. The methods include attaching a pre-fabricated porous ingrowth structure to a substrate by applying heat, or creating and bonding an in-situ-formed porous ingrowth structure from beads on a substrate by applying heat. In some embodiments, an oxidized metal surface of the substrate is diffusion hardened during the heating process. In some embodiments, a vacuum is applied during the heating process. In some embodiments, pressure is applied during the heating process. Also provided herein are assemblies for compressing the pre-fabricated porous ingrowth structure or the beads onto the substrate during the heating process.

Abstract: Devices, systems, and computer-implemented and surgical methods for providing and/or using optical, visual, and/or audio feedback when using a surgical instrument, such as to position and orient an implant are disclosed. A device includes a frame and a C-ring. The frame includes a fixation component optionally located at a first end and a tracking array optionally located at an opposing second end. The fixation component can be positioned at or near a center axis of the C-ring and is configured to releasably engage a surgical instrument. The tracking array may include tracking elements, such as reflective surfaces. The C-ring may include a plurality of light sources optionally arranged in a radial pattern. The light sources may be selectively illuminated based on a determined realignment to provide optical feedback with respect to at least a direction in which the surgical instrument should be moved to achieve a planned alignment.

IPC: A61B17/92

Abstract: An orthopedic surgical instrument or impactor is disclosed. The surgical instrument being configured to provide a first forward energy or motion to drive a surgical tool (e.g., a broach, a rasp, a cutting tool, etc.) and/or an orthopedic implant (e.g., an intramedullary nail, a stem, etc.) into a patient's bone and a second reverse energy or motion to, for example, remove a stuck or lodged surgical tool or implant from a patient's bone. In one embodiment, the surgical instrument incorporates dual springs and dual masses (impactors) to store and release energy on demand to deliver an impact force in both forward and reverse directions. In one embodiment, the surgical instrument may also include a forward energy adjuster and a reverse energy adjuster so that a user can independently adjust the amount of energy provided in the forward and reverse directions as well as a means to adjust impact frequency.

Abstract: Anchor delivery systems include anchors having a generally cylindrical body with a rail on top for positioning within a delivery device slot. The rail incorporates a side-bulge as a retaining feature which axially extends along a majority of the length of the rail. The bulge interferes with a corresponding hourglass cutout in the delivery device slot to prevent the anchor from stripping out of the delivery device when the delivery device is retracted through tissue. The anchors are symmetrical along a length and width to facilitate loading within the delivery device. The distal portion of the delivery device includes a series of distally-extending barbs that intentionally change the penetration force required to push the device tip through tissue.

Abstract: A tissue repair assembly is disclosed, including a soft anchor body and at 5 least a first suture operably coupled to the anchor body. Tensioning on first and/or second ends of first suture may deploy the anchor body to a second configuration, in which the anchor body is axially compressed and radially extended. The tissue repair assembly may also include a means to cinch around a portion of a first and/or second suture and knotlessly lock the tissue repair assembly. Some embodiments 10 may include a pre-formed knot. In some embodiments, the preformed knot may be a nail knot, provided wrapped around an insertion instrument and configured to receive and cinch around a suture extending therethrough.
