    Abstract: The invention relates to a heat sink parameter determination apparatus for determining a parameter of a heat sink like a blood vessel within an object such as a person(3) by minimizing a deviation between a measured temperature distribution, which has preferentially been measured by ultrasound thermometry, and a modeled temperature distribution, wherein the modeled temperature distribution is modeled based on a provided heat source parameter like the location of an ablation needle (2) and the heat sink parameter to be determined by using a given thermal model. This determination of heat sink parameters, which may be geometric and/or flow parameters, considers the real temperature distribution and is thus based on real heat sink influences on the temperature distribution. This can lead to an improved determination of heat sink parameters and hence to a more accurate temperature distribution which may be determined based on the determined heat sink parameters.

    Abstract: A device, system and method for temperature-based lesion formation assessment and mapping functionality using an accessory usable with an over-the-wire balloon catheter. The device may include a first annular element, a plurality of wires coupled to the first annular element, and a second annular element, the plurality of wires passing from the first annular element through the second annular element and into an elongate wire conduit coupled to the second annular element. At least one of the plurality of wires may include at least one temperature sensor and/or at least one mapping electrode. The first annular element coupled to an outer surface of a sheath. As a balloon catheter is advanced out of the sheath lumen, the distal tip of the catheter engages the second annular element and pushes the wires out of the sheath lumen, everting them over the balloon of the catheter.
