Abstract:
1. A method of delivering an implantable sensing device to a first cardiovascular cavity of a human patient for sensing at least one pressure within the cardiovascular system of the patient for assessing a cardiovascular condition of the patient, the method comprising the steps of placing the sensing device in a second cardiovascular cavity having a larger diameter than the first cardiovascular cavity, and thereafter releasing the sensing device within the second cardiovascular cavity, delivering the sensing device to the first cardiovascular cavity by pushing the sensing device with blood flowing from the second cardiovascular cavity to the first cardiovascular cavity, and operating the sensing device to sense a pressure within the first cardiovascular cavity, wherein the sensing device is sized and configured so as to secure itself within the first cardiovascular cavity as the sensing device moves therethrough, and so as to be oriented once secured to sense the pressure within the first cardiovascular cavity, wherein the first cardiovascular cavity is a first pulmonary artery and the second cardiovascular cavity is a second pulmonary artery, and wherein the sensing device occludes the first pulmonary artery and is oriented within the first pulmonary artery for measuring pulmonary capillary wedge pressure.
