Publication number: 20180368896Abstract: A device for reducing and achieving fixation of a rib fracture may include a rib clip designed to partially encircle a rib bone without obstructing the intercostals nerve, wherein the rib clip is partially U-shaped. The rib clip may be built into a self-fixating plate. Alternatively, the rib clip may removably attach to an existing rib plate and, thus, be a standalone rib clip. The standalone rib clip may include a clip orifice extending therethrough to provide for attachment to the existing rib plate.Type: ApplicationFiled: August 31, 2017Publication date: December 27, 2018Inventor: Ledford Lee Powell

Publication number: 20180368897Abstract: A device for reducing and achieving fixation of a rib fracture may include a self-fixating plate having an elongate perforated band with a plurality of screw orifices extending therethrough; and at least one rib clip extending outward from an edge of the perforated band. The self-fixating plate may have an initial coiled configuration and a secondary deployed configuration, wherein the deployed configuration is less coiled curved than the initial coiled configuration.Type: ApplicationFiled: February 28, 2018Publication date: December 27, 2018Inventor: Ledford Lee Powell

Publication number: 20180368898Abstract: Various bone screws configured to be implanted into bone and methods of use are provided. In an exemplary embodiment, a bone screw is provided with an elongate shank and a head with a drive feature configured to couple with a driver tool for being advanced into bone and a threaded shank. The screw can have a distal end or tip that has one or more cutting edges thereon configured to cut bone as the bone screw is inserted into bone.Type: ApplicationFiled: June 27, 2017Publication date: December 27, 2018Inventors: John DiVincenzo, Nicholas Pavento, Ralph Solitario, Eric Biester

Publication number: 20180368899Abstract: The invention provides a system for the preshearing based control of the flow and deformation behavior, i.e., the setting kinetics, and the time dependent shear viscosity, elasticity of aqueous cementitious suspensions that can be used for bone repair and regeneration. The dynamic cement microstructure is tailored to the demands of the surgical tasks (faster/slower setting) or additive manufacturing tasks (lower/higher viscosity) by application of various preshearing conditions. The relationships between the preshearing and pressurization conditions and the setting kinetics and the time dependent changes in elasticity and viscosity are complex and characterization of viscoelastic properties using advanced rheological characterization techniques including small-amplitude oscillatory and steady torsional rheometry is needed a priori to enable such tailoring.Type: ApplicationFiled: April 30, 2018Publication date: December 27, 2018Inventors: Erdem Şahin, Dilhan M.

Publication number: 20180368900Abstract: An access cannula that defines a portal to the tissue to which the material is delivered. The access cannula includes a valve. The valve prevents the flow of material out of the access cannula. The valve also prevents the pressure head at the site at which the access cannula is inserted from forcing a delivery cannula out of the access cannula.Type: ApplicationFiled: August 31, 2018Publication date: December 27, 2018Applicant: Stryker CorporationInventor: David Robert Boboltz

Publication number: 20180368901Abstract: A subperiosteal syringe assembly for storing, containing and delivering bone graft material to a location within the tissue of a jaw for use in a medical procedure. The syringe assembly has a lumen body that is maneuverable within the subperiosteal tissue to deposit bone graft material at the desired surgical site. Embodiments include a lumen body that has a flat shape, such as an elliptical shape. A plunger is provided to deliver the syringe contents. The syringe may be loaded with bone graft material, and some embodiments may be supplied pre-loaded with bone graft material. An end cap seals the open end of the lumen, and may function as a septum that may be punctured with a needle to introduce a liquid substance, such as a growth factor, into the lumen where the bone material is stored. The syringe may be designed to incorporate surgical navigation and laparoscopic systems.Type: ApplicationFiled: June 23, 2017Publication date: December 27, 2018Inventor: Ernesto A. Lee

Publication number: 20180368902Abstract: An apparatus to limit a seating depth of a fastener can include a cylindrical housing, a pin, a driver, and a biasing element. The cylindrical housing can include a proximal portion couplable to a tool, a distal portion engageable with a workpiece, and a bore extending from an opening on the distal portion towards the proximal portion along a longitudinal axis of the housing. The pin can be secured to the housing and can extend radially inward into the bore. The driver can be translatable within the bore of the housing and can extend beyond the opening on the distal portion to engage the fastener. The driver can include a slot that can be engageable with the pin to receive a torque from the pin and can rotate with the housing to transfer the torque to a fastener when the pin engages the slot.Type: ApplicationFiled: June 21, 2018Publication date: December 27, 2018Inventors: Pierre Milor, Bruno Ichelmann, Kevin Flaquiere

Publication number: 20180368903Abstract: A guide wire control device for advancing a guide wire into a body or a portion of the body, comprises a handle member (1), a lever (2) and a spring means (3). The spring means (3) holds the lever (2) relative to the handle member (1) such that the longitudinal axis of a through-hole (9) in the lever (2) is misaligned with the longitudinal axis of an elongate passage (4) in the handle member (1) for locking the guide wire control device to a guide wire (5) extending through said elongate passage and said through-hole. Pivotal movement of the lever (2) brings the longitudinal axis of the through-hole (9) into alignment or substantial alignment with the longitudinal axis of the elongate passage (4) for release of the guide wire (5). Pivotal movement of the lever (2) also brings the longitudinal axis of the through-hole (9) into renewed misalignment with the longitudinal axis of the elongate passage (4) for clamping of the guide wire (5).Type: ApplicationFiled: December 16, 2014Publication date: December 27, 2018Inventors: Christian Lutz, Klaus Dorawa
