  • Patent number: 7799035
    Abstract: A curable material delivery cannula device is disclosed. The device includes a cannula and a hub. The cannula includes an open proximal end, a deflectable segment forming a pre-set curve, a lumen, and side orifice(s) adjacent, and proximally spaced from, the distal end and fluidly connected to the lumen. When inserted within a guide cannula, the deflectable segment straightens. When distally extended from the guide cannula, the deflectable segment reverts to the curved shape. The distal end has a blunt tip for non-traumatic interface with bodily material. During use, curable material, such as bone cement, is delivered from the side orifice(s) in a radial direction relative to the lumen.

  • Publication number: 20100087828
    Abstract: A curable material delivery cannula device and method are disclosed. The device includes a cannula and a hub. The cannula includes an open proximal end, a deflectable segment forming a pre-set curve, a lumen, and side orifice(s) adjacent, and proximally spaced from, the distal end and fluidly connected to the lumen. When inserted within a guide cannula, the deflectable segment straightens. When distally extended from the guide cannula, the deflectable segment reverts to the curved shape, which may be used to create a void in the bone for receiving curable material. The distal end has a blunt tip for non-traumatic interface with bodily material. During use, curable material, such as bone cement, is delivered from the side orifice(s) in a radial direction relative to the lumen.

  • Publication number: 20080116224
    Abstract: An apparatus and method for mixing two components and delivering the mixture to a patient. The apparatus contains a mixing chamber for mixing a liquid component and a powder component. The liquid component and powder component are mixed within the mixing chamber by rotation of a collapsible mixing element. A high strength cartridge capable of withstanding high opposing axial loads from the mixing chamber and a threaded rod generates force to drive the curable material from the mixing chamber. A plunger connected to the rod is then advanced through the mixing chamber to force the mixture out of the mixing chamber and deliver the mixture to the patient.

  • Publication number: 20070197971
    Abstract: An apparatus and method for introducing material into an injection site of a patient is disclosed. The device includes a cannula and a carrier. The cannula is inserted into an injection site of a patient. The carrier is connected to an injector containing a volume of material. Material may be pre-loaded into the carrier so that the material is delivered to a distal end of the carrier from the injector and the carrier is thus pre-loaded with material. A portion of the distal end of the pre-loaded carrier is inserted into the cannula and material is delivered to an injection site. The supply section can be rotatable with respect to the longitudinal axis of the inner section.
