Abstract: A method for compensating for phase discontinuities on a communication device is described. A communication device may determine a desired output power. The communication device may determine a Digital-to-Analog Converter (DAC) gain corresponding to the desired output power. The communication device may determine a cumulative phase offset based on the DAC gain. The communication device may apply the DAC gain. The communication device may apply a phase compensation to a rotator to adjust for the cumulative phase offset.

Abstract: An endovascular conduit device and method for use during cardiac lead extraction and other vascular procedures is presented. The endovascular conduit device includes an outer-sheath, a conduit member, a lumen member, and an inflation member to control the flow of fluid within the conduit member. The endovascular conduit device may be positioned intravascularly as cardiac lead extraction or other procedures are performed. If necessary, as in the case of a vascular tear, the endovascular conduit device further includes expandable members that are activated to allow blood to be forced into the channel of the conduit member. Blood may then be contained and directed safely to bypass the area of vessel injury. In doing so, a catastrophic circulatory collapse or shock is prevented.
