Dispensing system and method
A dispensing system includes a device having a body extending along a longitudinal axis between opposite proximal and distal ends. The body includes a proximal chamber, a distal chamber and a wall between the chambers. The body includes a first port in communication with the proximal chamber and a second port in communication with the distal chamber. A shaft is movably positioned within the body. The shaft extending through the wall and comprising a proximal plunger positioned within the proximal chamber and a distal plunger positioned within the distal chamber. Wherein pressure introduced through an opening in the proximal end moves the shaft such that the proximal plunger moves a material within the proximal chamber out of the first port and the distal plunger moves a material within the distal chamber out of the second port. Kits and methods of use are disclosed.
Graft material injector system and method
A graft material injector device and method are disclosed. The injector device includes an elongated injector tube and a side loading aperture for receiving graft material. A graft material loader and a cover for the side loading aperture may optionally be included.
Bone material hydration devices and methods
A device for hydrating particulate bone material is provided. The device comprises a tubular member having an interior surface and an exterior surface. The interior surface is configured to receive the particulate bone material and a hydration fluid. The exterior surface has a plurality of pores configured to allow the hydration fluid to flow into the interior surface of the tubular member and hydrate the particulate bone material. The plurality of pores are smaller in size than the particulate bone material. Methods of dispensing particulate the bone material are also provided.
Bone cement applicator with clampable delivery plunger
One aspect relates to a bone cement applicator having a cartridge with an interior, a cartridge head with a delivery opening, a mixing member which is movable in the interior with a mixing rod. A delivery plunger is arranged in the cartridge and is mounted in the interior and is pressable in the direction of the delivery opening. The delivery plunger rests with an outer cylindrical circumferential surface against an inner wall of the cartridge. A clamping element is arranged on the inner wall of the cartridge in the region of a back side of the interior. The clamping element projects out of the inner wall of the cartridge. The cylindrical circumferential surface of the delivery plunger is resiliently deformable by the clamping element in the direction of a central cylinder axis, such that the delivery plunger is clampable in place with the at least one clamping element on the back side of the cartridge.
BONE MATERIAL DISPENSING SYSTEM AND METHODS OF USE
A bone material dispensing system is provided. The bone material dispensing system comprises a loading device having a perimeter surrounding a base plane and a rim, the perimeter comprising a side wall extending along a longitudinal axis and a bar joining the side wall at a corner of the perimeter and extending in a direction transverse to the longitudinal axis, the base plane comprising a loading surface bordered by the side wall along the longitudinal axis, the loading surface having an end edge extending in a direction transverse to the longitudinal axis such that the side wall, the bar and the end edge form a rim adjacent to the loading surface and the bar. A method of loading bone material with the bone material dispensing system is also provided.
DISPENSING SYSTEM AND METHODS OF USE
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.
Graft preparation and delivery instruments and method
Embodiments of the invention include instruments (100, 200, 400, 1100, 1400, 2100, 2400, 3400) and methods useful in delivering graft material (1) to a surgical site. Some embodiments may particularly be directed to forming a graft (1) and accurately and effectively handling and delivering the graft (1) to a surgical site arthroscopically. Graft material (1) may include blood components such as clotted fibrin derived from a patient's or a donor's blood.
ARTICULATED INSTRUMENTATION AND METHODS OF USING THE SAME
Articulated instruments that include tools for disrupting and/or distracting tissue, and methods of using the same.
DEVICE FOR PROVIDING BONE CEMENT DOUGH
A device for providing a bone cement dough from two starting components, comprising a hollow cylindrical cartridge with an interior space, wherein a bone cement powder as the first starting component is stored in a proximal part of the interior space, and at least two pouches containing a monomer liquid as a second starting component are stored in a distal part of the interior space, wherein a dispensing plunger axially movable in the interior space is arranged between the bone cement powder and the at least two pouches, and a delivery plunger axially movable in the interior space is arranged on a side of the at least two pouches that is axially opposite the dispensing plunger, wherein the proximal part and the distal part of the interior space are fluidically connected to one another via a conduit means.
APPARATUS FOR PROVIDING A LIQUID COMPONENT OF A BONE CEMENT DOUGH, SYSTEM AND METHOD FOR PROVIDING A BONE CEMENT DOUGH
An apparatus for providing a liquid component as a first starting component of a bone cement dough from two starting components, comprising a receptacle in which a tank containing the liquid component can be stored, an opening means for opening the tank, a reservoir, fluidically connected to the receptacle, for receiving the liquid component from the tank, at least one port for fluidically connecting the apparatus to a syringe in which a powder component can be stored as a second starting component of the bone cement dough, and at least one conducting means which fluidically connects the reservoir and the at least one port to one another.
