Patent number: 9775652Abstract: A bone plate system is provided. The system includes two or more fastener locks stacked on top of each other and located between two holes in a plate adapted to receive bone fasteners. An actuator is provided between the locks. As the actuator is advanced, the locks are moved sequentially into position, firstly, to prevent one or more bone fasteners from backing out of the plate while permitting the fasteners to angulate and, secondly, to lock the angulation of the bone fasteners while still providing back out protection in situ. An expandable bone plate having a top plate interconnected to a bottom plate by a rack and pinion is provided. The rotation of the pinion with a driver lengthens or shortens the plate incrementally for custom length adjustment. The length is fixed in position with the simple removal of the driver and no further step is required to lock the plate length.Type: GrantFiled: October 10, 2016Date of Patent: October 3, 2017Assignee: Mastros Innovations, LLCInventors: Moti Altarac, Joey Reglos, Michael Schneier, Brian Stuart Grossman, Michael Davis, Dale Lawrence Leibert, John Fredrick Stephani

Patent number: 8591556Abstract: Novel bone screw and plate assemblies including locking confirmation mechanisms are provided. In certain cases, a locking confirmation mechanism is operably attached to the plate, and comprises a toggling arm having an upper portion, a mid-portion and a lower portion. When a bone screw is positioned in a plate in an unlocked configuration, the locking confirmation mechanism assumes a first position. When the bone screw is positioned in the plate in a locked configuration, this causes the locking confirmation mechanism to pivot and assume a second position. The locking confirmation mechanism thus provides a convenient visual and/or tactile means to assess when the screw is in a locked configuration.Type: GrantFiled: July 19, 2011Date of Patent: November 26, 2013Assignee: Globus Medical, Inc.Inventors: Noah Hansell, Michael Black

Patent number: 7785327Abstract: A locking screw assembly is provided which allows installation into a plate-like member using relatively little force, but which requires relatively great force for removal. The fastener has an annular locking ring provided within a groove in the head of the screw to allow the screw to sit within or flush with the anterior surface of the plate. The through-hole in the plate which receives the locking screw comprises an entrance, a collar section, an undercut, and an exit. The locking ring resides within the undercut. The locking ring has a leading surface that is chamfered or radiused and a trailing surface that is flat. The chamfer allows the locking ring to easily be inserted into the through-hole by interacting with a lead chamfer in the entrance. After installation, the flat trailing surface abuts a lip adjoining the collar section and the undercut and prevents the screw from being easily removed from the through-hole.Type: GrantFiled: June 1, 2005Date of Patent: August 31, 2010Assignee: Theken Spine, LLCInventors: Richard R.

Patent number: 7652190Abstract: An integrated wound dressing system and method including a bandage and a self-contained receptacle that stores treatment material for the care and treatment of wounds. The treatment material is easily accessible and can be removed from the receptacle through an exit. The treatment material can then be used to control bleeding and/or clean the wound before dressing. The bandage may include a layer of plastic that acts as an occlusion barrier to reduce heat loss and maintain moisture levels at the wound site. The occlusion barrier also acts to prevent the passage of air into or out of the wound site. The bandage also includes fasteners that act to prevent unintentional unraveling and to secure the bandage during final packaging. These fasteners help facilitate the wrapping of amputations, stumps, and extremities. The integrated wound dressing system provides an all-in-one system for treating and dressing wounds and reduces the time required to do so.Type: GrantFiled: April 18, 2007Date of Patent: January 26, 2010Assignee: Tactical Medical Solution, Inc.Inventor: Ross A.
