Microplegia systems describe herein use syringe pumps that are controlled in a coordinated fashion to deliver cardioplegia medications during an open-heart surgery at the prescribed dosages and/or rates. The microplegia systems link the delivery rate of the syringe pumps with the delivery rate of the cardioplegia blood flow rate. A perfusionist can enter prescribed drug concentrations, desired ratios between drug and blood, and the expected dose for each phase of the myocardial protection scheme that will take place during the open-heart surgery. Additionally, or alternatively, the syringe pump systems described herein can also be used to deliver other non-cardioplegia types of therapeutic substances

Cardiothoracic surgical devices with a dual lumen cannula (8) that cooperates with a clamping assembly (35) for facilitating a CPB. The dual lumen cannula (8) has a distal end portion (8d) configured to reside inside an aorta (A) of a patient. The distal end portion (8d) has a first lumen (9) and a second lumen (10) in fluid isolation. The first lumen (9) has a lumen orifice (13) that faces a first direction inside the aorta and the second lumen (10) comprises a lumen orifice (15) that faces a second direction that is different than the first direction inside the aorta. The clamp assembly (35) is coupled to the dual lumen cannula (8) and configured with first and second clamp arms (1351, 1352) that are configured to align with the distal end portion (8d) of the dual lumen cannula (8) and clamp against opposing external surfaces of a vessel wall of the aorta to compress the vessel wall against the distal end portion (8d) of the dual lumen cannula (8) and thereby provide first and second fluidly isolated segments of the aorta.

The present disclosure relates to a system for extracorporeal blood circulation, including an oxygenator which includes a heat exchanger configured for warming or cooling blood in extracorporeal blood circulation of a patient, and a heater/cooler configured for exchanging a quantity of heat with the heat exchanger, wherein the heater/cooler includes a thermoelectric heater/cooler and wherein the heater/cooler (14) is connected to the heat exchanger (11) by a thermal connecting element (15).
