Patent JP-4401299-B2 (JP)
IPC: A61F2/44
Filed: 2003-01-16
Granted: 2010-01-20
Abstract: The present invention is a prosthetic for replacement of at least a part of the nucleus of a intravertebral disc. The prosthetic device is composed of at least two substantially parallel soft layers of an elastically deformable hydrogel and at least one more rigid layer, the more rigid layer having less compressibility than the soft layers, being adjacent to the soft layers, and firmly attached to them. In some embodiments, the soft layers have the same thickness and composition. Typically, the prosthesis has more than one more rigid layer and these more rigid layers have the same thickness and composition. The number of soft layers is usually one more than the number of more rigid layers, with, e.g., at least three soft layers. The invention also includes a method of prosthesis production, which involves prefabricating soft and more rigid layers; stacking at least two prefabricated soft and at least one prefabricated more rigid layer in a substantially parallel fashion into their final form, and, permitting the layers to firmly connect to one another by mutual interaction. In this method, at least one type of the layers is prefabricated in the dehydrated state, which is done by dehydrating stretched foil in an apparatus preventing its contraction and thereby decreasing its area. There is at least partial dehydration of the prosthesis under pressure applied in a direction tangent to the planes of the layers. In preferred embodiments, while in the state of almost full dehydration, the implant is sterilized using ionizing radiation or a gaseous chemical agent, after which it is partially rehydrated within a sterile wrapper using water vapor.

Abstract: A wireless communication device comprises a number of sub-systems operably coupled to a data interface for routeing data between the number of sub-systems. A clock generation function generates a clock signal substantially at a data transfer rate to be used over the data interface whereby the clock signal is generated at a rate that minimises harmonic content of the clock signal at operational frequencies of the wireless communication device. Thus, a suitable data rate is selected and supported by the data interface that accommodates the desired bandwidth, clock rate and/or chip rate of the functional elements that are coupled by the data interface within the wireless communication device, whilst minimising the effects of harmonic interference from the clock signal(s).
