A curved inflatable bone tamp includes an outer shaft defining a passageway. An inner shaft is positioned within the passageway. The inner shaft extends between opposite first and second end. The inner shaft defines a lumen. The inner shaft is curved between the first end and the second end. A first leg of a balloon is coupled to the outer shaft and a second leg of the balloon is coupled to the inner shaft such that a material can flow through the lumen and into the balloon to inflate the balloon. The balloon includes a wall having a variable thickness between the legs when the balloon is uninflated and a uniform thickness between the legs when the balloon is inflated. Kits, systems and methods are disclosed.

A device for mixing and dispensing bone material is provided. The device comprises a tubular member having an interior surface configured to receive bone material and a fluid to mix the bone material disposed within the tubular member. The tubular member is flexible and has a proximal opening configured to slidably receive a plunger, and a distal opening configured to dispense a mixed bone material from the interior surface of the tubular member. The plunger is less flexible than the tubular member. Methods of mixing and dispensing bone material are also provided.

A percutaneous minimally-invasive procedure to prevent a potential fracture in an osteoporotic vertebra of an osteoporotic patient who has no history of vertebral fracture is provided by minimally-invasively injecting a non-dispersive, biocompatible and resorbable calcium-based cement paste into the osteoporotic vertebral body.

A composite implant comprising an injectable matrix material which is flowable and settable, and at least one reinforcing element for integration with the injectable matrix material, the at least one reinforcing element adding sufficient strength to the injectable matrix material such that when the composite implant is disposed in a cavity in a bone, the composite implant supports the bone.

A method for treating a bone, the method comprising: selecting at least one reinforcing element to be combined with an injectable matrix material so as to together form a composite implant capable of supporting the bone; positioning the at least one reinforcing element in a cavity in the bone; flowing the injectable matrix material into the cavity in the bone so that the injectable matrix material interfaces with the at least one reinforcing element; and transforming the injectable matrix material from a flowable state to a non-flowable state so as to establish a static structure for the composite implant, such that the composite implant supports the adjacent bone.

The invention comprises a system for securing an implant to a bone comprising an implant which is affixed to the bone, a grout or bone cement comprising a composition that cures in an exothermic reaction and which is capable of securing the implant to the bone in a cured state, a device which provides access to the grout or bone cement in position on the bone and a tester which measures temperature over time to detect the exothermic reaction so as to determine when the composition reaches cure. The tester comprises a sensor joined to a circuit and to an indicator that emits a signal in response to a current emitted to the circuit by the sensor.

The present disclosure relates to systems and methods for mixing and injecting fluid treatment, such as cement to treat bone or hard tissue. In some embodiments, a mixing apparatus may facilitate mixing within a syringe. Additionally, the syringe may be configured to extract bone cement from a cement mixer. A syringe for mixing and injecting cement may include a detachable handle that may be detached after extracting bone cement from a mixer to facilitate coupling to a high-pressure syringe for injection.

The invention provides the internal fixation system of multi-function adjustable spine posterior screw-rod. It not only includes the vertebral plate, but also includes the adjustable connecting rod, screw and lock nut. Among them, vertebral plate is curved, its internal cambered surface directly faces the spine, and external cambered surface of vertebral plate is equipped with a reinforcing rib. The vertebral plate is set with the perforative injecting hole, and the external cambered surface of vertebral plate is set with the located block. The surface of the located block is set with the concave threaded hole, and the located block on two sides of the threaded hole is set with the U-shaped bracket. The top of screw expands to form a locking block, which surface is set with the concave locking hole. The locking block on both sides of locking hole is set with the U-shaped locking groove.
