Injectable bone graft material having a biocompatible, resorbable polymer and a biocompatible, resorbable inorganic material exhibiting macro, meso, and microporosities.

The present disclosure relates to bone cement formulations that have an extended working time for use in vertebroplasty procedures and other osteoplasty procedures together with cement injectors that include energy delivery systems for on-demand control of cement viscosity and flow parameters. The bone cement formulations may include a liquid component having at least one monomer and a non-liquid component including polymer particles and benzoyl peroxide (BPO). The non-liquid component may be further configured to allow controlled exposure of the BPO to the liquid monomer so as to enable control of the viscosity of the bone cement composition.

Embodiments are directed to fusion implants, insertion instruments, and methods of using the same for implanting one or more fusion implants across a sacroiliac joint and into an ilium and sacrum for fusing the sacroiliac joint. In some cases, fusion-promoting material may be inserted in the fusion implant for further promoting fusion across the sacroiliac joint. In some cases, neurophysiologic monitoring may be performed as the fusion implants are placed across the sacroiliac joint.

A bone graft loading system includes a loading funnel, syringe, cannula, plunger, and loading tool. The loading funnel includes an interior passageway to receive the cannula and a syringe docking portion. The syringe may be coupled to the syringe docking portion so that it extends along a longitudinal axis that is transverse to the longitudinal axes of the cannula and the loading funnel. A user may advance bone graft from the syringe to a holding area of the loading funnel. The user may then move the loading tool through the holding area and into the interior space of the cannula to load the cannula with bone graft. This process may be repeated until the cannula is fully loaded with bone graft. The cannula and the plunger inside the cannula may then be removed from the loading funnel and coupled to an injector assembly for use in surgery.

Methods of filling bone cavities are provided. The methods use a bone cement mixing and delivery device that includes a shaft extending along an axis from a first end to a second end and including a passageway. The first end includes an adapter having a first opening that is in communication with the passageway. The second end includes a second opening that is in communication with the passageway. The shaft includes a mixing portion between the first and second ends. A connector includes a central portion that that is coupled to the adapter. The central portion includes a channel that is in communication with the first opening. The connector includes first and second ports that extend from the central portion. The first port includes a first lumen that is in communication with the channel. The second port includes a second lumen that is in communication with the channel.

A technique for simultaneously forming a plurality of paste filled tunnels. The plurality of paste filled tunnels are connected to a surgical tube directly or indirectly and emptied one after another, until a desired amount of the paste is injected into a bone cavity, organ or a tissue via the surgical tube. The paste may be a bone cement paste, a drug powder paste, viscous fluid or gel. The injected bone cement paste will set in the bone cavity to act as a medical implant.

A fluid pressurizing and displacement device which is configured for both macro movement and micro movement of a plunger. In order to execute micro movement of the plunger, a user need only rotate the plunger; to execute macro movement of the plunger, a user need only push or pull the plunger. This simplicity in use is possible because a half-nut (or other suitable structure within the device) remains engaged with the plunger, except when the plunger is being pushed or pulled by its operator. All user motions are simple and intuitive.

A method for implanting a medical device for implantation in a mammal joint. The method comprising the steps of creating an opening reaching from outside of the human body into the joint, providing said artificial contacting surface to said joint, fixating the artificial contacting surface to the joint, implanting said reservoir in the human body, and lubricating the artificial contacting surface with use of a lubricating fluid contained in said reservoir.

The present invention relates to an apparatus, system and method for delivery of bone graft material in a patient's spine. The graft delivery device according to various embodiments delivers and disperses biologic material to a disc space and without withdrawal from the surgical site. In various embodiments, the graft delivery device includes an elongate hollow tube configured to receive bone graft material, a plunger adapted to extend in the elongate hollow tube and urge the bone graft material through the elongate hollow tube, and an injection device (such as a syringe) configured to contain the bone graft material therein and to connect to an open proximal end of the elongate hollow tube, to discharge the bone graft material from the first injection device into the elongate hollow tube.
