    摘要： Disclosed is an anchoring element for an implantable prosthesis that includes a barb, wherein the anchoring element, which includes a basal portion, comprises a thin layer of material, such as a cannula or sheet of metal, that extends or wraps at least partially around the strut of the prosthesis to which it is attached. The barb is configured to extend outward from the basal portion to penetrate adjacent tissue. The anchoring element is either permanently affixed to the strut, such as by laser or spot welding, crimping, or some other method of bonding, or allowed to slide longitudinally over the strut between two points or stops in order to relieve any excessive loads placed upon the barb that could cause fracture. The anchoring element and strut may be configured to limit axial rotation of the barb, while still allowing longitudinal movement. In another embodiment, the slidable anchoring element may be manipulated following initial deployment to reorient the barb toward the implantation site.

    摘要： A balloon catheter for insertion into a vertebral body is provided. The balloon catheter includes a shaft having a proximal end and a distal end. A lumen extends through the shaft along a longitudinal axis. An inflatable balloon having an uninflated configuration and an inflated configuration is disposed near the distal end of the shaft. The balloon has a proximal portion and a distal portion and an interior and an exterior. The lumen is in fluid communication with the interior of the balloon. An expandable band is wrapped around a section of the exterior of the balloon in a generally proximal-distal direction. The balloon catheter is configured to be positioned within the vertebral body such that the expandable band is configured to prevent leakage of a bone-filling material in a generally lateral direction relative to a vertebral body and facilitate adhesion of the bone-filling material within the vertebral body.

    摘要： A mixing system and method for forming bone cement by mixing liquid monomer methyl methacrylate (MMA) with a powder component comprising polymethyl methacrylate (PMMA). A container of MMA is received in a bag. The MMA is emptied from the container into the bag, and a syringe is connected to the bag in substantially leak-free manner to receive the MMA from the bag. The syringe is disconnected from the bag and thereafter connected to a receptacle housing the powder component. The MMA is then transferred into the receptacle in substantially leak-free manner.
