Human receptor selective atrial natriuretic factor variants containing various substitutions, especially G16R, show equal potency and binding affinity for the human A-receptor but have decreased affinity for the human clearance or C-receptor. These ANF variants have natriuretic, diuretic and vasorelaxant activity but have increased metabolic stability, making them suitable for treating congestive heart failure, acute kidney failure and renal hypertension.

The present invention is directed to using a thermoregulatory sensor in conjunction with a cooling-normothermic-heating device that applies a desired thermal energy to a target heat exchange surface of a mammal that is under negative pressure. The thermoregulatory sensor, unlike the prior art, does not initiate and / or control the thermal energy applied to the mammal. Instead the thermoregulatory sensor initiates, controls and / or manages the negative pressure applied to the target heat exchange surface. By initiating, controlling and / or managing the negative pressure, (1) the vasodilation of the target heat exchange surface is also controlled and / or managed and / or (2) thermal communion between the exchange surfaces (skin and heat exchanger) is controlled, and / or managed.

A “relaxoscope” (100) detects the degree of arterial endothelial function. Impairment of arterial endothelial function is an early event in atherosclerosis and correlates with the major risk factors for cardiovascular disease. An artery (115), such as the brachial artery (BA) is measured for diameter before and after several minutes of either vasoconstriction or vasorelaxafion. The change in arterial diameter is a measure of flow-mediated vasomodification (FMVM). The relaxoscope induces an artificial pulse (128) at a superficial radial artery (115) via a linear actuator (120). An ultrasonic Doppler stethoscope (130) detects this pulse 10-20 cm proximal to the point of pulse induction (125). The delay between pulse application and detection provides the pulse transit time (PTT). By measuring PTT before (160) and after arterial diameter change (170), FMVM may be measured based on the changes in PTT caused by changes in vessel caliber, smooth muscle tone and wall thickness.

A method for stimulating perfusion and minimizing postischemic reperfusion injury. A patient is selected having compromised perfusion in a tissue or in the microcirculation of an organ. An ultrasound transducer is applied to a location near the tissue. The transducer is activated to initiate exposure of the tissue to ultrasound at a frequency of 100 KHz to 2.5 MHz for 0.5 to 15 minutes duration, wherein local vasodilatation is stimulated. In certain cases, the methods further include a step of confirming that local vasodilatation is stimulated by measuring enhancement in perfusion. Ultrasound devices are also described for carrying out the methods. The devices and methods can be used to enhance myocardial perfusion, cerebral perfusion, and perfusion of transplanted tissues.

A negative pressure, thermal energy device has an enclosure that receives a patient's body part. The body part is positioned in the enclosure and contacts a thermal energy contacting surface. The thermal energy contacting surface transfers its thermal energy to the body part. While in the enclosure, the body part is also exposed to a negative pressure to cause vasodilation. The combination of the vasodilation and the thermal energy transfer alter the patient's body core temperature. To ensure the body part remains in contact with the thermal contacting surface, the enclosure has a portion thereof that moves when negative pressure is in the enclosure. When the negative pressure is applied, the deforming enclosure material is pulled toward the body part to provide a positive pressure on the body part that ensures the body part effectively contacts the thermal energy contacting surface.
