摘要： Methods and apparatus for estimating a measure of cardiac contractility based on a set of features determined from a set of signals associated with a mechanical circulatory support device are provided. The method includes determining, using computer processor, a set of features based, at least in part, on the set of signals, providing the set of features as input to a machine learning model trained to output a measure of cardiac contractility, and performing an action based, at least in part, on the measure of cardiac contractility output by the machine learning model.

摘要： Apparatus and methods are described including a ventricular assist device that includes an axial shaft and an impeller disposed on the axial shaft, the impeller being configured to pump blood. A frame is disposed around the impeller. The distal end of the axial shaft is configured to engage with a distal thrust bearing such as to prevent the axial shaft from undergoing axial motion in response to variations in the pressure gradient against which the impeller pumps blood. An impeller-stabilizing spring is disposed around the axial shaft between a distal end of the impeller and the thrust bearing, the impeller-stabilizing spring being configured to stabilize the distal end of the impeller. Other applications are also described.

摘要： Apparatus and methods are described including a blood pump that includes an impeller configured to be delivered through vasculature of a subject while the impeller is in a radially-constrained configuration. The impeller is configured to self-expand to a non-radially-constrained configuration, and to pump blood while in the non-radially-constrained configuration. A ratio between (a) a diameter of the impeller when the impeller is in its non-radially-constrained configuration at a location at which the diameter of the impeller is at its maximum and (b) a diameter of the impeller when the impeller is in its radially-constrained configuration is greater than 7:2. Other applications are also described.

摘要： A catheter pump is disclosed. The catheter pump can include an impeller and a catheter body having a lumen in which waste fluid flows proximally therethrough during operation of the catheter pump. The catheter pump can also include a drive shaft disposed inside the catheter body. A motor assembly can include a chamber. The motor assembly can include a rotor disposed in the at least a portion of the chamber, the rotor mechanically coupled with a proximal portion of the drive shaft such that rotation of the rotor causes the drive shaft to rotate, the rotor including a longitudinal rotor lumen therethrough. The motor assembly can also comprise a stator assembly disposed about the rotor. During operation of the catheter pump, the waste fluid flows from the lumen into the chamber such that at least a portion of the waste fluid flows proximally through the longitudinal rotor lumen.

摘要： The invention relates to a blood pump. The blood pump comprises a flexible drive shaft guided in a catheter, a conveying element connected to the drive shaft in a distal region of the drive shaft, and a motor, wherein the motor has a stator and a rotor mounted such that it can move in the stator. The stator comprises a winding and the rotor comprises a rotor magnet. In addition, the drive shaft is connected to the rotor at a proximal end of the drive shaft. The stator and the rotor are nondetachably connected to one another, and form a gap with a ring-shaped cross-section, which is delimited by the rotor and the stator.

摘要： The invention relates to a fluid pump, in particular to a liquid pump having a rotor with at last one rotor blade for conveying the fluid, the rotor being variable with respect to its diameter between a first, compressed state and a second expanded state. In order to produce a simple compressibility and expandability of the rotor of the pump, it is provided according to the invention that at least one rotor blade is deformable between a first state which it assumes in the compressed state of the rotor and a second state which it assumes in the expanded state of the rotor by means of a fluid counterpressure during a rotation of the rotor during pump operation.
