Abstract: The present invention relates to a modular prosthetic conduit implantable within a mammal and a method of surgically implanting and replacing such a conduit. Specifically, the present invention is directed toward a conduit comprising a first conduit member composed of a biocompatible alloplast and coated on its exterior surface with a porous biocompatible tissue-bonding material. The present invention is further directed toward a second conduit member composed of a biocompatible alloplast. The second conduit member contains a region or component that can be expanded radially by mechanical, hydraulic, chemical, electrical, temperature sensitive or other physical means. The second component can be easily slid into or out of the first conduit member and at temperatures approaching a mammal's body temperature, it expands to form a watertight "docking" fit within the first conduit member. The second conduit member may contain remotely actuable valve and pump. Both the first conduit member and the second conduit member may be altered with respect to size, geometry and shape so as to affect conduits, reservoirs, sampling chambers and tissue-prosthesis interfaces. By way of altered size, geometry and shape, the modular prosthetic conduit may serve to drain bodily fluids, give access to intracorporeal organs, deliver drugs or chemicals or energies into the body. Both conduits may be impregnated with antimicrobials to lessen the risk of bacterial colonization.

Abstract: The invention relates to a telephone system where frequency multiplexed analogue telephone signals and digital data signals are transmitted over a line (3). Incoming calls are announced to the customer installation (2) by a ringing indication signal having an amplitude between 1 and 30 V RMS, that is much less than the regular ringing and therefore easier to be generated, and moreover having a smoother shape than a rectangular shape. Upon receiving the ringing indication signal, the customer installation (2) locally generates and provides a full ringing signal to a telephone (32). The amplitude of this local ringing signal is higher than the amplitude of the ringing indication signal, but the line with the digital data signal is isolated from the customer telephone equipment at the time the ringing signal is generated, so as to avoid disturbance of the digital data transmission by the ringing current, which is in the prior art a serious source of impulsive noise. <IMAGE>
