    摘要: Methods and devices for augmenting bone, such as in performing vertebroplasty are disclosed. A bone implant with enhanced interfacial shear strength can include a container, such as a mesh bag, with a sidewall and an interior chamber portion. The sidewall can include an open-celled matrix and can be filled with a first media to promote bone ingrowth and enhanced interfacial shear strength. The interior chamber can be filled with a second media to prevent crack propagation. Delivery catheters with releasable coupling features to the implant are also disclosed.
