摘要:
A percutaneous path is created into a bone having an interior volume occupied, at least in part, by a cancellous bone, e.g., a vertebral body. An expandable stent structure is introduced into the cancellous bone by deployment of a tool through the percutaneous path into the cancellous bone. The expandable stent structure is expanded and the tool withdrawn, leaving the expandable stent structure expanded inside the cancellous bone. Expansion of the expandable stent structure within cancellous bone can, e.g., compact cancellous bone, and/or create a cavity in cancellous bone, and/or move fractured cortical bone.

Systems and methods for delivering material into bone deploy a cannula through soft tissue to establish a subcutaneous path into bone. A material is introduced into bone through the cannula. The systems and methods advance a tamping instrument through the cannula to urge material residing in the cannula into bone. The introducing step delivers material at a pressure no greater than about 360 psi.

Methods and apparatus are provided for loading therapeutic materials into brachytherapy needles. The apparatus comprises an apparatus with chambers, and radioactive seed and spacer cartridges received therein. The apparatus may be used in conjunction with a standard brachytherapy needle coupled to the distal end of the apparatus. The plunger dislodges seeds and spacers from the cartridge chambers to load the needle with a predetermined packing arrangement.

The present invention provides an electrical connector for a motorized conveyor pulley which has a plate having a first side and a second side and an outer surface. The plate is preferably constructed of an insulating glass material. At least one electrical connector is supplied which provides electrical communication from the first side to the second side. The plate is formed around the electrical connector to fluidly seal the first side from the second side. In another aspect of the present invention, the electrical connector has an outer shell structure having an internal area and an outer area. A portion of the internal area encapsulates and is bonded to the outer surface of the plate.
