摘要： The present disclosure relates to a method for determining an actual pump rate and/or for calibrating a blood pump of a blood treatment apparatus connected to an extracorporeal blood circuit. The method includes providing a blood pump of a blood treatment apparatus or establishing a signal communication to a blood pump. The blood pump comprises, or is connected to at least a first source for a fluid and at least a first line of an extracorporeal blood circuit which is connected to the first source downstream. Furthermore, the blood pump comprises, or is connected to, a reception unit for receiving fluids of the first source wherein the reception unit is in fluid communication with the first line. The reception unit is arranged on or at a first weighing device such that the weight of the reception unit or of its content is determined using the weighing device.

摘要： Apparatus and methods are described including a ventricular assist device that includes an impeller configured to be placed inside a subject's left ventricle. A frame is disposed around the impeller, the frame defining generally-cylindrical central portion, and a proximal conical portion that widens from a proximal end of the frame to a proximal end of the generally-cylindrical central portion. A motor drives the impeller to pump blood from the left ventricle to the subject's aorta, by rotation of the impeller. The impeller is configured to be disposed at least partially within the proximal conical portion of the frame during at least some of a time during which the impeller rotates. Other applications are also described.

摘要： Apparatus comprising and methods are described including a blood pump that includes an axial shaft, and an impeller disposed on the axial shaft. The impeller is configured to pump blood of the subject by rotating. The impeller and the axial shaft are configured to undergo axial back-and-forth motion during operation of the impeller. A distal tip element is disposed at a distal end of the blood pump. The distal tip element defines an axial-shaft-receiving tube, configured to receive at least a portion of the axial shaft during forward motion of the axial shaft. The distal tip element additionally defines an atraumatic distal tip portion disposed distally of the axial-shaft-receiving tube. Other applications are also described.

摘要： A blood pump-oxygenator system comprises at least one blood pump, an oxygenator, inflow and outflow cannulas, connected to form a closed series circuit operable as a cardiopulmonary bypass system for extracorporeal processing of the patient's blood. The blood pump conveys blood through the circuit from the patient into the inflow cannula, through the oxygenator and out of the outflow cannula back into the patient. A manifold is connected between the inflow and outflow cannulas so blood passes through the manifold, wherein the manifold accommodates the blood pump and the oxygenator to form a recirculation loop configured to recirculate at least part of the blood in the circuit so the blood passes over the oxygenator multiple times. An extra blood pump is positioned at the outflow cannula to deliver a set volume to the patient, controllable independently from the blood pump that circulates the blood in the manifold including the oxygenator.

摘要： A method and device to assist the performance of a heart with at least one pump that is formed as a rotary pump and driven via magneto coupling. The pump includes a magnetically driven rotor rotatable within a surrounding rotor housing to act upon blood flowing from an inflow tube toward the magnetically driven rotor, and a second magnetic device axially aligned with the inflow tube and positioned to magnetically drive rotation of the magnetically driven rotor via the magneto coupling.
