Abstract: The present invention relates to an apparatus and method for near-simultaneous and integrated delivery of bone graft material during the placement of surgical cages or other medical implants in a patient's spine. The integrated fusion cage and graft delivery device according to various embodiments delivers and disperses biologic material through a fusion cage to a disc space and, without withdrawal from the surgical site, may selectively detach the fusion cage for deposit to the same disc space. The integrated fusion cage and graft delivery device is formed such that a hollow tube and plunger selectively and controllably place bone graft material and a fusion cage in or adjacent to the bone graft receiving area. In one embodiment, the integrated fusion cage is an expandable integrated fusion cage. In another embodiment, the bone graft material is loaded into a breech area in the hollow tube.

A shaft into a shaft guide in the body which intersects the beak guide to temporarily latching the shaft to the body via a mounting fixture the shaft with the beak; and, wherein the body has a face end and a tail end.

Abstract: Disclosed are aspects of exemplars of torque-limiting devices, methods and mechanisms exemplars methods may include placing an actuator in a tool containment interface of a handle; movable mounting a tool portion with an actuation catch and a work piece engaging region (WER) in the interface; applying sufficient force to the movable mounting to the handle may be via pins, guides and slots. Said catch may be one of a body catch and a lever catch; and, the actuator terminates on one of a ball shaped end that forms and interface with the body catch and a force lever that forms an interface with the lever catch.

Abstract: The disclosure includes a connection method to fluidly connect a fluid pathway in a handle is formed co-linearly or axially and connects to a lumen through a tool and shaft. The body and movable latch may be an integral single molded plastic part connected by a flexible. In operation actuating the movable latch to raise or lower a latching beak within a corresponding open guide in the plastic body. The shaft fits into a shaft guide in the body which intersects the beak guide to temporarily latch the shaft to the body via a mounting fixture the shaft with the beak; and, wherein the body has a face end and a tail end.

Abstract: Disclosed are aspects of exemplars of torque-limiting devices, methods and mechanisms. Exemplary methods may include placing an actuator in a tool containment interface of a handle, the interface being fluidly connected to an adjustment interface and adjustable via a fixation fastener; movably mounting a tool portion with an actuation catch and a work piece engaging region (WER) in the interface; applying sufficient force to the movable mounting to the handle may be via pins, guides and slots. Said catch may be one of a body catch and a lever catch; and, the actuator terminates on one of a ball shaped end that forms an interface with the body catch and a force lever that forms an interface with the lever catch.

Abstract: Aspects of novel connection systems and methods are disclosed herein. A partially hollow nose is configured to one of connect a pathway to a body catch to accept a quick connect body (QCB) or mate with a connection system configured to be inserted into a shaped cavity in the nose; and, a quick connect module (QCM) and the nose are configured to cooperate to accept insertion of the QCB through the side wall of the nose into the body catch of the QCM; wherein the QCB affixes the QCM into the nose; and, wherein pushing on the button at one end of the QCB compresses the integral biasing arm of said QCB opening a catch and release interface to accept a tool.

Abstract: A flexible plastic, resin or polymer material forming a trial plate for use is surgery of bones including spine and extremities. The trial plate having at least one radioopaque region and which may have one radiolucent region. In some instances a main body includes one or more arms formed of subparts. Between the main body and subparts and between the subparts are rangible regions such a ribs or unbroken edges surrounding windows configured as predetermined break points to disassociate portions of an arm from the whole.

Abstract: A floor mat is provided, including a mat body having an upper surface, and a heel pad disposed on the upper surface with a heel pad upper surface and an underside from which depend a plurality of isolated support members projecting generally perpendicularly from the underside such that the heel pad provides compressive strength and enhanced flexibility.

Abstract: Lumbar and cervical interbody or intervertebral devices for implantation between adjacent vertebrae of a spine and/or within intermediary canals of long bones are characterized by a body defining a superior end and an inferior end whose surfaces have serrations or teeth thereon forming anti-backout structures that allow implantation of the body but inhibit removal or backing out therefrom. The one-way structures may extend from the anterior end to the posterior end. The one-way structures may take different shapes but are always configured to allow insertion of the interbody device in an anterior-first manner while preventing and/or inhibiting the interbody device from backing out posteriorly. The various interbody devices may be further characterized by a body defining a cavity that is in communication with the superior and inferior ends of the body and at least one lateral side thereof via openings in the body.

Abstract: A clamp system includes a first clamp, a second clamp, and a fixation rod. The first clamp at least partially defines a first jaw for receiving a support rod and a central opening. The second clamp at least partially defines a second jaw for receiving a pin and a central opening. At least one of the first clamp and the second clamp comprises a boss for rotatably positioning the first clamp relative to the second clamp. The fixation rod is received in the central openings of the first clamp and the second clamp for selectively securing a position of the first clamp relative to the second clamp.
