The intra-aortic balloon pump, also called the balloon pump, is a machine that helps the heart pump blood throughout the body. It consists of two parts: a balloon inserted into the aorta, one of the large arteries through which blood passes from the heart to the rest of the body; and a machine outside the body.
Device for determining a characteristic point in the cardiac cycle
The present invention relates to a device for determining a characteristic point in the cardiac cycle that comprises means for calculating the curve of the blood flow rate D(t) in the aorta from the curve of the arterial blood pressure signal P(t) and determining from the curve of the blood flow rate D(t) in each cardiac cycle the time at which an incisura point lies. The device can be used for activating an intra-aortal balloon pump (IABP).

An inflatable balloon pump can be anchored with respect to a wall of the aorta for endoscopic surgical positioning with respect to the aorta of the patient. After engagement of the anchor member in an endoscopically selected location of the aorta, the inflatable balloon pump can be cyclically inflated and deflated to assist the cardiac function based on measured clinical parameters of the patient. The balloon pump can include tapered longitudinal ends and / or be segmented into a plurality of pumping chamber subsegments, each pumping chamber subsegment separated by a flexible power conduit link, where the diameter of the pumping chamber subsegments are independent of one another. Anchor members can be provided located adjacent at least one longitudinal end of the pump, or each longitudinal end of each inflatable chamber defining the pump, or sheathing at least one of the inflatable chambers defining the pump.

Method of inotropic treatment of circulatory failure using hypothermia
InactiveUS7172586B1Control rateIncrease contractilityStentsSurgeryHeart transplantationAutomatic control
A method for treating cardiac failure such as congestive heart failure by application of hypothermia. Hypothermia may be applied by endovascular cooling using a heat exchange catheter circulating heat exchange fluid between an external heat exchanger controlled using temperature feedback from a temperature probe on or in the patient to cool the heart to a sufficiently low temperature for a sufficient length of time to increase cardiac output and improve the vascular condition of the patient. The patient may be maintained in the hypothermic condition for a period of time and is then re-warmed slowly and controllably. The endovascular temperature management may be controlled automatically in response to a temperature probe on the patient, and shivering while the patient is cool may be combated using surface warming and anti-shivering drugs. The method is applicable to treat congestive heart failure and may be used repeatedly on the same patient to restore that patient to adequate heart function when the vascular condition of that patient has become unacceptable. The method may be used to maintain a patient until a heart transplant becomes available. The method may be used to stabilize a patient's condition to allow needed surgery or intervention. The method may be used in conjunction with other treatments including drugs, balloon pumps, pacing devices and ventricular assist devices.

The invention relates to a push-type elastic balloon pump, which comprises an elastic balloon, a pump body, a pressure lever, an inlet check valve, an outlet check valve, a nozzle, a bottle cap and the like, wherein the lower edge of the elastic balloon is impacted into the pump body to form seal. The elastic balloon is pushed with a hand to deform, the intracavity pressure of the balloon rises, and the inlet check valve and the outlet check valve are opened and closed to discharge liquid through the nozzle; the push is stopped, the elastic balloon is reset to lower the intracavity pressure of the balloon, and the inlet check valve and the outlet check valve are opened and closed to suck the liquid through a suction pipe. A piston and a reset spring of an original piston pump are replaced by the elastic balloon functionally, so that the height of a pump cylinder is greatly reduced. The friction problem brought by dynamic seal of the piston of the original piston pump is also solved by the push-type elastic balloon pump, and therefore, labor is saved. The push-type elastic balloon pump with double cavities can be put in a comb, and the comb becomes a hair-coloring comb by configuring comb teeth, a comb handle and two bags of hair-coloring liquid. The push-type elastic balloon pump is simple in structure and low in cost, is convenient for various aesthetic modeling and is in favor of beautifying life.
