    Abstract: A vascular perfusion device and system include a first fluid pathway, a second fluid pathway, and a pressure source configured to expand and collapse the second fluid pathway. The second fluid pathway can be at least partially disposed within the first fluid pathway, and the second fluid pathway can have an expanded state and a collapsed state, such that in the expanded state, the second fluid pathway displaces a fluid in the first fluid pathway. The first fluid pathway can be one of a perfusate pathway or a gas pathway, and the second fluid pathway can be the other. When a perfusate is disposed in the perfusate pathway, and a gas is disposed in the gas pathway, at least a portion of the gas crosses from the gas pathway to the perfusate pathway to mix with the perfusate when the second fluid pathway can displace the fluid.

    Abstract: 回転操作入力部の誤操作を防止しつつ、緊急時において流体の流量値を短時間で変更可能な流体流量制御装置及び体外循環装置を提供すること。　流体流量制御装置（１０）は、流量調整手段（Ｐ）から送り出される流体の流量値を回転操作入力部（６）の回転操作により制御し、回転操作入力部（６）における所定の単位回転量の回転操作が予め設定された第１設定回転量まで連続して行われた場合に流量調整手段（Ｐ）から送り出される流体の流量値を変更せずに、回転操作入力部（６）における所定の単位回転量の回転操作が第１設定回転量を超えて連続して行われた場合に、第１設定回転量を超えた回転量に応じて、流量調整手段（Ｐ）から送り出される流体の流量値を変更するように制御する。

    Abstract: Mechanical circulatory support systems and methods are disclosed herein. In some examples, the present technology comprises a system for providing cardiac support to a patient where the system comprises a first elongated shaft configured to receive a delivery catheter therethrough, a second elongated shaft, and a pressure source coupled to the first and second elongated shafts. The first elongated shaft may have a distal end portion configured to be intravascularly positioned at a first cardiovascular location, and the second elongated shaft may have a distal end portion configured to be intravascularly positioned at a second cardiovascular location downstream of the first location. Pressure generated by the pressure source pulls blood from the first location proximally through the first shaft to the pressure source, then pushes the blood distally through the second shaft and into circulatory flow at the second cardiovascular location, thereby providing mechanical circulatory support to the patient.
