A device for producing a bone cement dough from a monomer liquid and a cement powder and dispensing the bone cement dough. The device includes a cartridge holding the cement powder in an internal space. A monomer receptacle screws onto the cartridge, forms a chamber, and has a plunger with a passage that is permeable to gases and the monomer liquid but is impermeable to the cement powder and that connects the internal space to the chamber. The plunger tightly closes the internal space with the exception of the passage. A gas supply opening is arranged in the wall of the monomer receptacle. A monomer liquid container holds the monomer liquid and is located in the chamber. An opening facility opens the container, and closes the gas supply opening before opening the container. Also provided is a method for producing and dispensing the bone cement dough.

A device for dispensing a bone cement from a container, comprising a connecting element for reversibly connecting the device to the container, a rod-like dispensing element, which at least partially has an external thread, a switching system, which at least partially has a first internal thread, wherein the first internal thread can be coupled in a positive manner to the external thread in such a way that the dispensing element can be axially screwed into the container in a first coupled switching system position, and the dispensing element can be pushed freely axially into the container in a second decoupled switching system position.

A balloon, a medical device, and a medical procedure for discoplasty are disclosed. The balloon has a compressed, collapsed or folded balloon body containing a first chamber for, in use, receiving injected bone cement. With the bone cement filled and cured therein, the balloon acts as a support in tissue of an intervertebral disc while preventing the bone cement from leakage and dispersion. The deployed balloon body defines a second chamber running therethrough. The second chamber is configured to receive a material or cells that activate osteogenesis and/or osteo-induction, so that the material or cells injected into the second chamber through a second sprue form osteocytes or induce human spontaneous local cellular differentiation to in turn form osteocytes in the cavity of the intervertebral disc and connect vertebrae above and below the intervertebral disc, thereby securely anchoring the balloon within the intervertebral space.

One aspect relates to a method for providing a bone cement from two starting components, having a hollow cylinder-shaped first container, in which a monomer liquid as first starting component can be stored, a hollow cylinder-shaped second container comprising a container wall, a first internal space, and a second internal space, whereby a bone cement powder as second starting component can be stored in the first internal space, and whereby the monomer liquid can be conveyed into the second internal space, a fluid-conducting conveying means arranged between the first internal space and the second internal space, whereby the first container and the second container are axially connected to each other.

A bone material dispensing device is provided. The bone material dispensing device comprises a housing having a proximal end, a distal end, and a longitudinal axis. The proximal end having a first opening and the distal end having a second opening. The first opening and the second opening configured to slidably receive at least a portion of a plunger. A locking member is provided that is pivotably connected to an upper surface of the housing and extends adjacent to the upper surface of the housing. The locking member comprises a locking surface extending adjacent to the distal end of the housing configured to engage a portion of a tubular member, a funnel, or a combination thereof. The locking member is movable in a locking position to lock the portion of the tubular member, the funnel, or the combination thereof with the housing. A bone material dispensing system and a method of implanting bone material with the bone material dispensing system are also provided.

An apparatus and methods for delivery of reinforcing materials to a weakened or fractured bone is disclosed. An apparatus for delivering a reinforcing mixture to a bone including a tube having a proximal end, a distal end, and a longitudinal axis therebetween, wherein the tube has at least one inner lumen capable of allowing a bone reinforcing mixture to pass therethrough; a balloon engaging the tube wherein the balloon expands from a substantially deflated state to a substantially inflated state upon the bone reinforcing mixture entering the balloon; and at least one light guide extending through the tube into the balloon to guide a light into the balloon.

A spinal joint distraction system for treating a facet joint including articular surfaces having a contour is disclosed and may include a delivery device including a generally tubular structure adapted to engage a facet joint, an implant adapted to be delivered through the delivery device and into the facet joint, the implant comprising two members arranged in opposed position, and an implant distractor comprising a generally elongate member adapted to advance between the two members of the implant causing separation of the members and distraction of the facet joint, wherein the implant is adapted to conform to the shape of the implant distractor and/or the articular surfaces of the facet upon being delivered to the facet joint. Several embodiments of a system, several embodiments of an implant, and several methods are disclosed including a method for interbody fusion.

An implantable medical device, for implantation in a mammal knee joint, comprising an artificial contacting surface adapted to replace at least one contacting surface of the knee joint and to be lubricated when implanted in said joint. The medical device further comprises a reservoir comprising a movable wall portion defining the volume of the reservoir, at least one inlet adapted to receive a lubricating fluid from the reservoir, at least one channel at least partly integrated in said artificial contacting surface, wherein the channel is fluidly connected with said at least one inlet for distributing said lubricating fluid to the surface of said artificial contacting surface. The medical device further comprises an operation device adapted to non-invasively transport said lubricating fluid from said reservoir to said artificial contacting surface, and an implantable injection port for refilling said reservoir, wherein the movable wall portion is moved when the reservoir is refilled, such that the volume of the reservoir is increased.

Medical devices for injecting materials into patients are disclosed. The devices can include a body having a handle and a lever. The devices can also include a delivery tube comprising a passageway along a longitudinal axis and a nozzle with an opening, the delivery tube configured to couple with a distal end of the body. A driving rod can be inserted into the body and extend into the passageway, such that the lever can move the driving rod distally when the lever is actuated toward the handle. Methods of using the material delivery device are also disclosed.

A method for controlled delivery of fluids to the exterior of bone and surrounding tissue of a patient includes providing a cannulated bone rod. The method further includes creating an aperture in the skin of a patient and fixating the rod along bones or bone fragments using a spinal fixation system through the aperture. A spinal fixation system includes a bone screw having a longitudinal access and a bone rod configured to connect the bone screw to at least one additional bone screw. The bone rod is lateral to the longitudinal axis. The method further includes the steps of providing a fluid source, coupling the fluid source to the bone rod, and delivering a fluid from the fluid source into the bone rod. An additional method includes using the fixation system as a point of drainage for the posterolateral fusion site.
