Abstract: A valve and tether fixation mechanism includes an anchor, a tether, and a prosthetic heart valve. The anchor may be for anchoring a prosthetic heart valve in a native heart valve. The tether may have a distal end coupled to the anchor. The tether may extend proximally from the anchor and connect to a tensioning mechanism. The prosthetic valve may be configured to translate along the tether. The valve may have a tether connecting portion configured to allow for adjustment of the tension in the tether and affix the prosthetic valve to the tether at a desired tension.

Abstract: A system for communicating across conventional HVAC wiring is provided. The system includes a communication device having a communication module capable of inducing low power, high frequency current signals into a single control wire coupling, for example, a thermostat with a compressor. The communication module includes a power supply module that draws power sufficient to operate the communication module from the existing HVAC wiring, so as to eliminate any need for batteries or external power sources. A second communication module may be coupled to the single control wire. The second communication module operates as a transceiver sending communication signals to, and receiving communication signals from, the communication module. In one embodiment, the communication module is disposed within a building, for example coupled to an electronic thermostat, while the second communication module is disposed outside the building near the compressor.
