Tree-based data exploration and data-driven protocol
A method for providing a treatment recommendation to a physician for treating a patient is disclosed. The method comprises determining, from a processor in communication with a patient data repository, a first treatment recommendation based on a combination of selected patient demographics from the patient data repository applicable to the patient, and operational parameters of a plurality of ventricular assist devices (VADs) suitable for treating the patient, the first treatment recommendation having a first survival rate and comprising the use of a first VAD. The method then obtains a first signal from using the first VAD on the patient. The method then determines a second treatment recommendation based on the first signal and the first treatment recommendation, the second treatment recommendation having a second survival rate. The method then provides the second treatment recommendation to the physician if the second survival rate is higher than the first survival rate.

Blood pump system for causing persistent increase in the overall diameter of a target vessel
A blood pump system for persistently increasing the overall diameter and lumen diameter of peripheral veins and arteries by persistently increasing the speed of blood and the wall shear stress in a peripheral vein or artery for a period of time sufficient to result in a persistent increase in the overall diameter and lumen diameter of the vessel is provided. The blood pump system includes a blood pump, blood conduit(s), a control system with optional sensors, and a power source. The pump system is configured to connect to the vascular system in a patient and pump blood at a desired rate and pulsatility. The pumping of blood is monitored and adjusted, as necessary, to maintain the desired elevated blood speed, wall shear stress, and desired pulsatility in the target vessel to optimize the rate and extent of persistent increase in the overall diameter and lumen diameter of the target vessel.
Treating Heart Tissue
Some systems and methods for treating heart tissue may include instruments for intermittently occluding the coronary sinus using a coronary sinus occlusion catheter device. In some embodiments, the coronary sinus occlusion catheter can be used before or during a coronary intervention procedure in which a blockage in a heart is repaired or removed.
VENTRICULAR ASSIST DEVICE CONTROL
A control device for a ventricular assist device (VAD) with settable speed levels. The control device includes an input configured to receive at least one measuring signal related to a physiological condition of the circulatory system of a patient receiving heart assistance by the VAD, where the control device is configured to derive an actual value of at least one characteristic parameter of the heart from one or more of the at least one measuring signal and to provide a refined actual value of the at least one characteristic parameter in which effects of physiologically caused fluctuations are eliminated or reduced. The control device further includes an output configured to output an updated setting value for the speed level, where the control device is configured to produce the updated setting value based on the refined actual value and a predeterminable set-point value.

The present invention relates to systems, methods and algorithms for determination of heart pump function and their use in livings subject are described. The invention further relates to complementary parts of such systems that work best in combination. Medical catheters, sheaths and shafts are disclosed that carry an arrangement of integrated digital sensor systems-on-chip (SoC) in the portion thereof residing inside the body. These devices combine at their portion that resides inside the body, the complete chain of signal transduction, signal analog-to-digital conversion and digital signal transmission, and allow to acquire single and multiple physical entities in a single setup. In specific instances the devices integrate wireless data transfer functionality, and in specific instances they integrate wireless energy harvesting for battery-free functionality. The present invention further describes complementary monitor systems that are suited for reception, processing and analysis of data acquired by such catheters/sheaths/shafts to yield a robust assessment of cardiac performance. Moreover, the present invention relates to innovations which render such systems applicable to patients with and without cardiac assist devices.
CONTROL SYSTEM
An extracorporeal life support device control system and method arranged to provide suitable gas and blood flow rates through an extracorporeal life support device. The control system comprises: a sensor arranged to detect and output a measurand, wherein the measurand is characteristic of a single autonomic nervous system output defining a metabolic demand; and a controller arranged to receive the measurand, and further arranged to control, according to the measurand: gas and/or liquid flow rates through an extracorporeal life support device; wherein the flow rates are arranged to provide blood gas concentrations similar to those arising from healthy lungs at the metabolic demand. In the case of patients with healthy lungs, the control system can control the blood flow rate without controlling gas flow rates through an oxygenator.
Hemodynamic assist device
A hemodynamic flow assist device includes a miniature pump, a basket-like cage enclosing and supporting the pump, and a motor to drive the pump. The device is implanted and retrieved in a minimally invasive manner via percutaneous access to a patient's artery. The device has a first, collapsed configuration to assist in implantation and a second, expanded configuration once deployed and active. The device is deployed within a patient's aorta and is secured in place via a self-expanding cage which engages the inner wall of the aorta. The device includes a helical screw pump with self-expanding blades, sensors, and anchoring structures. Also disclosed is a retrieval device to remove the hemodynamic flow assist device once it is no longer needed by the patient and an arterial closure device to close the artery access point after implantation and removal of the hemodynamic flow assist device. The hemodynamic flow assist device helps to increase blood flow in patients suffering from congestive heart failure and awaiting heart transplant.
