  • Patent number: 11850138
    Abstract: Systems and methods for implanting a shunt for regulating blood pressure between a patient's left and right atria are provided. The shunt comprises an anchor having a neck region, first and second end regions, and a conduit affixed with the anchor formed of a biocompatible material that is resistant to transmural and translation tissue ingrowth and that reduces a risk of paradoxical embolism. The shunt may be advanced through the sheath until the first region protrudes from the sheath and self-expands within the left atrium. The shunt and the sheath may then be retracted until the first region contacts the left side of the atrial septum. The sheath may further be retracted until the counterforce exerted by shunt tension on the atrial septum overcomes the friction of the retained portions of the shunt such that the second region is exposed from the sheath and self-expands within the second atrium.

  • Patent number: 11839711
    Abstract: A method of controlling thermal transfer in a perfusion system heat exchanger of an extracorporeal fluid treatment device for conditioning an extracorporeal patient fluid for administration to a patient comprises a step of providing a perfusion system heat exchanger, wherein the perfusion system heat exchanger comprises a first fluid passage for a liquid heat transfer medium and a second fluid passage for the extracorporeal patient fluid to be temperature-controlled via exchange of thermal energy with the heat transfer medium, and a step of providing the heat transfer medium through the first fluid passage. The heat transfer medium comprises a component with anti-microbial properties, such as glycol. The provision of antimicrobial fluid reduces the risk of microbe contamination of the extracorporeal fluid, and hence the risk of clinical complications.
