Pharmaceutical dosage forms having a highly hydrophilic fill material and a shell encapsulating the fill material are disclosed and described. Generally, the shell has at least one plasticizing agent therein in order to provide the shell with an effective plasticity. In one aspect, the shell may have included therein an amount of plasticizing agent that is sufficient to provide the shell with an effective plasticity upon migration of a portion of the plasticizing agent into the fill material. In another aspect, the plasticizing agent may have a solubility in the fill material of less than about 10% w/w. In yet another aspect, a combination of a plasticizing agent, and a plasticizing agent having a solubility in the fill material of less than about 10% w/w, may be presented in a total amount sufficient to provide the shell with an effective plasticity upon migration of plasticizing agent into the fill material.

Systems for treating a bone, e.g. a vertebral body, having an interior volume occupied, at least in part, by cancellous bone provide a first tool, a second tool, and a third tool. The first tool establishes a percutaneous access path to bone. The second tool is sized and configured to be introduced through the percutaneous access path to form a void that occupies less than the interior volume. The third tool places within the void through the percutaneous access path a volume of filling material. Related methods for treating a bone, e.g. a vertebral body, having an interior volume occupied, at least in part, by cancellous bone provide establishing a percutaneous access path to bone. A tool is introduced through the percutaneous access path and manipulated to form a void that occupies less than the interior volume. A volume of filling material is then placed within the void through the percutaneous access path.

A prosthetic device for implantation into a mammalian body comprised of a non-absorbable biocompatible flexible material shell or sac filled with various biocompatible gel filler materials. The gel filler materials are comprised of biocompatible glucomannan obtained from konjac hydrocolloid flour and other biocompatible hydrocolloids, producing a natural look and feel for the prosthetic implants, especially reconstructive prostheses such as breast implants.

Systems and methods provide for the fixation of osteoporotic and non-osteoporotic long bones, especially Colles' fractures. A cannula having a circumferential opening is inserted into cancellous bone and directed such that the circumferential opening faces the fracture. The cannula is further adapted to receive an expandable structure, the expandable structure being inserted through the cannula until it is in registration with the circumferential opening. The expandable structure is expanded through the circumferential opening into cancellous bone and toward the fracture. The expansion of the expandable structure through the circumferential opening toward the fracture causes compression of cancellous bone and moves fractured cortical bone, thus creating a cavity proximal to the fracture. The cavity is then filled with a flowable bone filling material and the material allowed to harden.

A system and method for treating bone abnormalities including vertebral compression fractures and the like. In one vertebroplasty method, a fill material is injected under high pressures into cancellous bone wherein the fill material includes a flowable bone cement component and an elastomeric polymer component that is carried therein. The elastomer component can further carry microscale or mesoscale reticulated elements. Under suitable injection pressures, the elastomeric component ultimately migrates within the flowable material to alter the apparent viscosity across the plume of fill material to accomplish multiple functions. For example, the differential in apparent viscosity across the fill material creates a broad load-distributing layer within cancellous bone for applying retraction forces to cortical bone endplates. The differential in apparent viscosity also transitions into a flow impermeable layer at the interface of cancellous bone and the flowable material to prevent extravasion of the flowable bone cement component.

The invention provides methods and apparatuses for fabricating a dual damascene structure on a substrate. First, trench lithography and trench patterning are performed on the surface of a substrate to etch a low-k dielectric material layer to a desired etch depth to form a trench prior to forming of a via. The trenches can be filled with an organic fill material and a dielectric hard mask layer can be deposited. Then, via lithography and via resist pattering are performed. Thereafter, the dielectric hard mask and the organic fill material are sequentially etched to form vias on the surface of the substrate, where the trenches are protected by the organic fill material from being etched. A bottom etch stop layer on the bottom of the vias is then etched and the organic fill material is striped. As a result, the invention provides good patterned profiles of the via and trench openings of a dual damascene structure.

In some aspects, a thickness of the first insulating liner is greater than a thickness of the second insulating liner.

Tools for use in the creation of cavities in bones. The tools include a probe, a cannula that provides percutaneous passageway to the interior of the treated bone, a bone tamp, and a system for delivering bone filler material into the cavity. The bone tamp has a shaft that is inserted into the bone through the cannula. The end of the shaft that is inserted into the bone may have a flapper tip that extends out of axial alignment with the shaft upon deployment by the physician. Once the tip is deployed, the bone tamp can be rotated to form the cavity. The cavity may then be treated with a medicament, filled with bone filler material, or both. Other tools and materials described herein may be used to lift or restore the treated bone closer to its natural anatomy.

Procedures for the fusion of the sacroiliac joint advantageously make use of an implant selected to distract the joint upon insertion and to maintain or increase tension upon insertion. The implant can have a varying structure along its length. In some method described herein for fusing the sacroiliac joint using an implant, an implant is screwed into the sacroiliac joint between the sacrum bone and the iliac bone. The implant comprises a shaft, a tool engagement flange at top end of the shaft, a pointed tip comprising no more than about 20 percent of the length of the screw, and threads spiraling around the shaft. For screws of particular interest, the volume displacement perpendicular to the shaft increases at least about 5 percent from a point adjacent the tip to a point near the top of the shaft. Some of the desirable screw designs can be used in other orthopedic application, especially situations involving varying bone hardness. Useful filler material can be formed from a blend of bone powder and bioactive agents.
