A dispensing system includes a main body having a base and an extension extending from the base. The extension includes an inner surface defining a passageway. The main body includes an opening that extends through the extension. The opening is in communication with the passageway. A first plunger is configured to be positioned within the passageway. The first plunger includes a lumen extending through and between opposite proximal and distal end surfaces of the first plunger. A second plunger is configured to be positioned within the lumen. Kits and methods are disclosed.

This invention relates generally to an instrumentation and implant system providing minimally invasive vertebral augmentation. The apparatus including an expandable membrane sized and configured to be located within a cavity in a patient's bone and having an interior volume for receiving bone filler material; a delivery cannula in communication with the membrane for providing bone filler material to the membrane; and an evacuation cannula in fluid communication with the membrane for receiving a portion of the provided bone filler material from the membrane.

A container for bone cement includes a first member defining a chamber, which contains a first ingredient. The chamber also includes a second member movably coupled to the first member. The second member includes a mixing device that is movably disposed within the first chamber, and the second member defines a second chamber containing a second ingredient. The container additional includes an opening device that selectively opens the second chamber and allows the second ingredient to enter from the second chamber into the first chamber. The mixing device is movable within the first chamber to promote mixing of the first ingredient and the second ingredient to prepare the bone cement. A corresponding method of preparing bone cement is also disclosed.

A method for stabilizing a vertebral body is provided. The method includes creating one or more openings into a central region of the vertebral body and dispose at least one cannula in the one or more openings. The method includes forming an internal cavity within the vertebral body through at least one of the one or more openings. The method includes injecting bone particles into the internal cavity of the vertebral body through a bone particle catheter disposed within the at least one cannula. The method includes applying pressure to the bone particles within the internal cavity of the vertebral body, thereby compressing them against a sidewall of the internal cavity. The method includes removing the at least one cannula and closing the one or more openings, thereby sealing the bone particles within the internal cavity of the vertebral body. A system for stabilizing a vertebral body is also provided.

An inflatable bone tamp includes an outer shaft defining a passageway. An inner shaft is positioned within the passageway. The inner shaft defines a lumen. A balloon has a first end coupled to the outer shaft and a second end coupled to the inner shaft such that material can flow through the lumen and into the balloon and exit the balloon through a channel between the inner and outer shafts. A valve is positioned within the channel. The valve is configured to move from a closed orientation in which the valve blocks the channel and an open orientation in which the does not block the channel. Kits, systems and methods are disclosed.

A dispensing system includes a main body having a base and an extension extending from the base. The extension includes an inner surface defining a passageway. The main body includes an opening that extends through the extension. The opening is in communication with the passageway. A first plunger is configured to be positioned within the passageway. The first plunger includes a lumen extending through and between opposite proximal and distal end surfaces of the first plunger. A second plunger is configured to be positioned within the lumen. Kits and methods are disclosed.

A bone cement delivery system includes a plunger configured to selectively displace bone cement from a cement reservoir through an exit port. Additionally, the system includes a flow diverter comprising a diverter inlet, a first diverter outlet, and a second diverter outlet. The system also includes a cannula coupler configured for connection to a delivery cannula for directing the bone cement to a target site, and a drool accumulator defining a drool volume for receiving residual bone cement. The flow diverter includes a valve arranged for selective movement between a first configuration where fluid communication is established between the cement reservoir and the drool volume; and where fluid communication is interrupted between the cement reservoir and the cannula coupler; and a second configuration where fluid communication is established between the cement reservoir and the cannula coupler; and where fluid communication is interrupted between the cement reservoir and the drool volume.

A medical implant comprises a slurry of bone particles that are injected into a vertebral body under pressure. The liquid component of the slurry may be aspirated while the slurry is being injected so that the bone particles of the slurry pack into the central area of the vertebral body to provide structural support. The injected slurry may be agitated during the procedure to maximize the structural strength of the implant after the procedure.

Bone cement applicators and methods apply a bone cement dough in the region of the spine. The applicators and method have at least one tubular cartridge with an internal space, containing starting components of the bone cement, at least one dispensing plunger that is mobile in longitudinal direction on the inside of the at least one cartridge, a hose, an application opening through which the bone cement dough is applicable, a three-way valve being arranged in the hose or on a side of the hose facing the at least one cartridge and in fluid connection with the opening of the at least one cartridge and/or a collecting container arranged on the three-way valve for accommodation of bone cement dough. The three-way valve is appropriately designed and/or arranged in the bone cement applicator such that it, being in a first position, provides a fluid connection between the application opening and the opening of the at least one cartridge and closes a passage to the collecting container and, being in a second position, provides a fluid connection between the application opening and the collecting container and closes a passage to the opening of the at least one cartridge.

Disclosed herein is a steerable and curvable drill that can be used for various applications including vertebroplasty. The drill can include an elongate, tubular body, having a proximal end, a distal end, and a central lumen extending therethrough; a deflectable zone on the distal end of the tubular body including one or more laser cuts, deflectable through an angular range; an insertable wire insertable into at least a portion of the central lumen of the elongate, tubular body; a handle on the proximal end of the tubular body; a deflection control on the handle; a drill control on the handle; a drive shaft within the elongate tubular body having a proximal end and a distal end; and a boring element on the distal end of the device for creating a cavity within bone. The boring element can be operably connected to the distal end of the drive shaft via a crimping mechanism. Systems and methods involving the drill are also disclosed.
