Controllers and methods for heart treatments are disclosed herein. The controller can include a communication module that can send and receive data from heart therapy devices. The controller can include memory including stored instruction. The controller can include a processor. The processor can receive a signal of an impending electrical treatment at a processor. The processor can determine a current operating parameter of a blood pump communicatingly coupled with the processor. The processor can determine an adjustment to the operating parameter of the blood pump to affect an impedance of heart tissue to be affected by the impending electrical treatment. The processor can control the blood pump according to the adjustment to the operating parameter of the blood pump.

An implantable blood pump including a housing having an inlet cannula, a rotor disposed within the housing, the rotor in fluid communication with the inlet cannula, a stator disposed within the housing, the stator configured to rotate the rotor when a current is applied to the stator, and at least one ultraviolet light emitter disposed within the housing.

An example renal support pump includes a renal support device including an outer catheter shaft having a longitudinal axis and a distal end region coupled to a renal pump assembly, wherein the renal pump assembly includes a frame and an impeller assembly, wherein the impeller assembly is disposed within the frame, and wherein the impeller assembly is configured to rotate relative to the frame about the longitudinal axis of the catheter shaft.

Devices, systems and methods for treating disorders characterized by low cardiac output. The devices, systems and methods use intra-aortic balloon counterpulsation in combination with hypothermia of all or a portion of a human or veterinary patient's body to improve coronary perfusion and cardiac output. To effect the hypothermia, a heat exchange catheter may be positioned in the a patient's vasculature separately from the intra-aortic balloon counterpulsation catheter. Alternatively, a combination Intra-aortic balloon counterpulsation/heat exchange catheter may be utilized. Such combination catheter comprises a) a catheter sized for insertion into the aorta, b) a counterpulsation balloon and c) a heat exchanger. A drive/control system receives temperature and electrocardiograph signals and drives the inflation/deflation of the counterpulsation balloon as well as the heating/cooling of the heat exchanger.

The invention relates to an aortic catheter (1) for insertion into the aorta (A), having a flexible tube (2), two occlusion balloons (3, 4), which are spaced part from one another and each of which is connected to a supply line (5, 6) for supplying a pumping medium (7) for inflating the occlusion balloons (3, 4), having at least one opening (8) arranged between the occlusion balloons (3, 4) in the tube (2) for supplying a cooling medium (9), which at least one opening (8) is connected to a first cooling medium supply line (10) running in the tube (2), and also relates to a resuscitation set (22) with such an aortic catheter (1), and a distal port (13) for supplying a cooling medium (9) in the direction of cerebral vessels is disposed in the tube (2), which distal port (13) is connected to a second cooling medium supply line (14) running in the tube (2).

Described is an intravascular device including a stent graft and at least one annular band. The intravascular device is configured for insertion into a blood vessel and configured to expand to contact the wall of a blood vessel after insertion therein. The annular band is configured to change in diameter in response to an applied potential difference. A method of maintaining and accelerating pulsatile blood flow includes positioning an annular band within a blood vessel, and causing the annular band to expand and contract in response to a current or potential difference.

A system for removing fluid from a urinary tract includes at least one sensor configured to detect signal(s) representative of pulmonary artery pressure and communicate signal(s) representative of the pulmonary artery pressure and a controller. The controller is configured to: receive and process the signal(s) from the at least one sensor to determine if the pulmonary artery pressure is above, below, or at a predetermined value; and provide a control signal, determined at least in part from the pulmonary artery pressure signal(s) received from the at least one sensor, to a negative pressure source to apply negative pressure to a urinary catheter to remove fluid from a urinary tract when the pulmonary artery pressure is above the predetermined value and to cease applying negative pressure when the pulmonary artery pressure is at or below the predetermined value.
