An extracorporeal bone compressing link and apparatus and method using same. Active devices that incorporate the extracorporeal bone compressing link can transport and compress bone through external means by acting on conventional bone fasteners including but not limited bone fasteners including but not limited to screws, pins or wires that penetrate through the skin and fixate into bone.

A method for force, displacement, and rate control of shape memory material implant. The rate of implant shape change as well as the force exerted on the surrounding tissue of the implant can be controlled by the surgeon and the extent of movement is controlled in circumstances where the bone element is free to move. The invention allows for the first time the fine control of force when fixating osteoporotic bone and rate of bone transport when working near the spinal cord. This heating profile of the implant provides the surgeon to control the extent of microstructure phase transformation so that the rate, force or extent of tissue movement can be controlled individually or together.
摘要:
A new shape changing staple and instrument for the fixation of structures to include bone tissue and industrial materials. This new staple stores elastic mechanical energy to exert force on fixated structures to enhance their security and in bone affect its healing response. This staple once placed changes shape in response to geometric changes in the materials structure, including healing bone tissue. The staple is advanced over prior staples due to its: 1) method of operation, 2) high strength, 3) method of insertion, 4) compressive force temperature independence, 5) energy storing staple retention and delivery system, 6) compatibility with reusable or single use product configuration, 7) efficient and cost effective manufacturing methods, and 8) reduction in the steps required to place the device. In addition to the staple's industrial application an embodiment for use in the fixation of the musculoskeletal system is shown with staple, cartridge, and extrusion handle.

摘要:
A shape-memory device manufactured from shape memory material includes multiple activation temperatures. The multiple activation temperatures arise from either the heat treatment of the device during manufacturing, or by combining different elements with different activation temperatures. To manufacture a shape-memory device with multiple activation temperatures, it is formed into a first shape. A first portion of the shape-memory device is heated to a first temperature, and a second portion of the shape-memory device is heated to a second temperature. The shape-memory device is then worked into a second shape. Accordingly, the first portion has a first transition temperature, and the second portion has a second transition temperature. In use, the shape-memory device is placed into a desired position. Energy is applied such that the first portion, second portion, or both portions are transformed.

An aircraft transparency has a heatable member to remove fog, ice and snow from the outer surface of the transparency. The heatable member includes a pair of spaced parallel bus bars with the ends of the bus bars offset from one another, and a coating including a plurality of spaced segments of an electrically conductive coating electrically connecting the bus bars. The ratio of the major diagonal to the minor diagonal is in the range of greater than 1 to 1.25 to more uniformly heat the coating and the outer surface of the transparency.

摘要:
A staple constructed from shape memory material provides the ability to move from a first shape to any point up to and including a second shape. The staple includes a bridge having a first member and a second member, and allows the second member of the bridge to change elevation with respect to the first member, thereby creating compressive forces, offset forces, or distraction forces. Upon the application of energy, the second member moves upward or downward to deliver forces, dependent upon a desired effect. The staple further includes first and second legs for attaching to first and second bones. The offsetting forces may be utilized to offset the second bone relative to the first bone, or to align offset bones. The bridge may include a transition member or plurality of transition members in communication with the first and second members, whereby the transition member moves about the first member.
摘要:
A plurality of electrical interconnections may be formed in an electrical device including a first component having a plurality of contact pads and a second component having a plurality of contact pads. The two components are placed in a confronting spaced relationship such that each contact pad of the first component locationally corresponds to one of the contact pads of the second component. The contact pads of the second component are further arranged such that at least two of the contact pads are laterally offset relative to their locationally corresponding contact pads on the first component with one of the at least two contact pads being offset in a first direction while the other is offset in another direction. A mass of conductive material is disposed between each contact pad of the first component and its corresponding contact pad of the second component. The masses of conductive material may be formed into columnar members wherein the columnar members are skewed when formed between a pair of relatively offset contact pads.
