摘要： A medical device with an implantable blood pump and a control and sensing unit configured to determine the flow rate generated by the blood pump when driven by an electric motor, wherein the flow rate is determined using peak-to-peak current data generated by the electric motor and, in some cases, associated heart rate data. In some embodiments, the validity of pulsatility of the resulting blood flow is determined and, if out of predetermined limits, an alarm may be actuated.

摘要： A device for extracting arterial and pulmonary embolisms is described herein. The device comprises a suction catheter and a return catheter attached to a reservoir. The reservoir comprises two filters that filter out any unwanted material from the blood. The device may be controlled by a console with a pedal. Blood containing unwanted material is suctioned out of a patient, is filtered in the reservoir, and is returned to the patient. The device prevents blood loss from the patient by returning the blood back to the patient after it is filtered. Furthermore, the filtration system is designed to also remove air from the blood as it is suctioned from the patient.

摘要： The present invention provides a blood pump-oxygenator system comprises at least one blood pump (10), an oxygenator (20), an inflow cannula (80), and an outflow cannula (90), which are connected so as to form a closed series circuit to be operable as a cardiopulmonary bypass system adapted for extracorporeal processing of the patient's blood. The blood pump (10) is configured to convey blood through the circuit from the patient into the inflow cannula (80), through the oxygenator (20) and out of the outflow cannula (90) back into the patient. A manifold (100) is connected between the inflow cannula (80) and the outflow cannula (90) so that the blood passes through the manifold (100), wherein the manifold accommodates the blood pump (10) and the oxygenator (20) and is designed so as to form a recirculation loop configured to recirculate at least part of the blood in the circuit such that the blood passes over the oxygenator (20) multiple times. The system further comprises an extra blood pump (50) positioned at the outflow cannula (90) and configured to deliver a set volume to the patient, wherein the extra pump (50) is configured to be controlled independently from the blood pump (10) that circulates the blood in the manifold (100) including the oxygenator (20).

摘要： Die vorliegende Erfindung betrifft Steuer- und Regeleinheiten für nicht-okklusive Blutpumpen einer extrakorporalen Kreislaufunterstützung sowie Systeme, umfassend eine solche Steuer- und Regeleinheit und entsprechende Verfahren. Entsprechend wird eine Steuer- und Regeleinheit (48) für eine nicht-okklusive Blutpumpe (40) einer extrakorporalen Kreislaufunterstützung vorgeschlagen, welche dazu eingerichtet ist, einen Flusswert (10) der extrakorporalen Kreislaufunterstützung zu empfangen, eine Messung eines arteriellen Drucks (12) und eines EKG-Signals (14) eines unterstützten Patienten (38) über einen vorgegebenen Zeitraum zu empfangen, einen mittleren arteriellen Druck (16) der extrakorporalen Kreislaufunterstützung oder des unterstützten Patienten anhand der Messung des arteriellen Drucks (12) und einen energieäquivalenten Druck (18) anhand des Flusswerts (10) und des arteriellen Drucks (16) zu bestimmen. Die Steuer- und Regeleinheit (48) ist auch dazu eingerichtet, einen erforderlichen Wert von mindestens einem Pulsparameter (20) der Blutpumpe (40) anhand des mittleren arteriellen Drucks (16), des energieäquivalenten Drucks (18) und des EKG-Signals (14) zu bestimmen, um ein Verhältnis des energieäquivalenten Drucks (18) zum mittleren arteriellen Druck (16) zu bewirken. Dieses ist größer als 1,0. Die Steuer- und Regeleinheit (48) ist weiterhin dazu eingerichtet, den Pulsparameter (20) in Abhängigkeit vom EKG-Signal (14) einzustellen (20).

摘要： Described herein are pumps that linearly reciprocate to assist with circulating blood within the body of a patient. Red blood cell damage may be avoided or minimized by such linear pump movement. The linearly reciprocating movement may also generate a pulsatile pumping cycle that mimics the natural pumping cycle of the heart. The pumps may be configured to reside at various body locations. For example, the pumps may be situated within the right ventricle, the left ventricle, the ascending aorta, the descending aorta, the thoracic aorta, or the abdominal aorta. In some instances, the pump may be deployed within the venous circulation. In other instances, the pump may reside outside the patient.
