1. A method of evaluating a patient’s vessel, comprising: introducing a first device into a patient vessel； introducing a second device into a patient vessel； moving the second device longitudinally along the patient’s vessel from a first position to a second position, wherein the first device is held in a fixed longitudinal position relative to the vessel ； obtaining the results of pressure measurements from the first and second devices, while the second device is moved in the longitudinal direction along the vessel； visual display of the vessel on the floor-based display ennyh pressure measurement； simulation of the visual display of the vessel to simulate one or more treatment options. 2. The method according to claim 1, characterized in that the first position is distal to at least one vessel stenosis. The method according to claim 2, characterized in that the second position is proximal to at least one stenosis of the vessel, while moving the second tool in the longitudinal direction along the vessel involves pulling. The method according to claim 1, characterized in that the first position is proximal to at least one vessel stenosis. The method according to claim 4, characterized in that the second position is distal to at least one vessel stenosis. The method according to claim 1, characterized in that the modification of the visual display of the vessel for modeling one or more treatment options includes: modifying the visual display of the vessel to model the first treatment option； modifying the visual display of the vessel to model the second treatment option； evaluating the modified visual selection1. Способ оценки сосуда пациента, предусматривающий:введение в сосуд пациента первого прибора；введение в сосуд пациента второго прибора；перемещение второго прибора в продольном направлении по сосуду пациента из первого положения во второе положение, при этом первый прибор удерживают в фиксированном продольном положении относительно сосуда；получение результатов
