Abstract: Methods and devices are shown for forming polymer fasteners into bone by expelling the polymer from a cannula. Devices and methods shown allow a user to form multiple fasteners of various sizes without re-loading a device. Devices and methods shown further provide temperature profiles during fastener formation that reduce or eliminate thermal necrosis. Devices and methods shown further provide fasteners with increased strength.

Abstract: The present invention provides an improved surgical retractor system useful for holding tissue away from a surgical site during a medical or dental procedure. In one embodiment, the surgical retractor system is comprised of a tubular member, such as a cannula, and a retractor member. In an embodiment, the retractor member may be ring shaped. The retractor member preferably may have an opening therethrough for receiving the cannula. An engaging member associated with the retractor member may be provided for rotatably engaging the cannula. In one embodiment, the cannula may have external threads that are releaseably engaged with the engaging member and allows the degree or amount of tissue retraction to be adjusted. The cannula may be configured to be used with and secured to a handle to facilitate using the retractor system. A method of using the retractor system is also disclosed.

Abstract: The present invention relates in general to implantable flexible bone composites, and method for preparing the same. The flexible bone composite includes at least one polymeric layer and at least one calcium-containing layer. The polymeric layer can be a polymeric layer including a synthetic polymer. The calcium-containing layer can include a calcium compound such as β-Ca3(PO4)2. The flexible bone composites of the invention are useful as bone void fillers and have improved handling characteristics.
