Systems and method are disclosed involving a pump control module configured to control an intravascular blood pump and display information about the intravascular blood pump, and a blood monitoring module configured to derive a value of a blood parameter from information received about a blood sample, such as information received from a blood monitoring sensor, and display the value of the blood parameter on the first display screen and/or on a second display screen. The system and method may also include predicting other parameters based on, e.g., the information received from the blood sample. The predictions may include, e.g., predictions of heart failure or bleeding events.

A method of assisting a heart of a patient using a dual lumen cannula includes inserting the dual lumen cannula into the patient, positioning a first infusion tube of the dual lumen cannula in an artery near the heart to pump blood thereto, positioning a second drainage tube of the dual lumen cannula in a chamber of the heart to drain blood therefrom. The dual lumen cannula has a plurality of infusion apertures extending through a sidewall of the first infusion tube at a distal end of the first infusion tube; and a plurality of drainage apertures extending through a sidewall of the second drainage tube at a distal end of the second drainage tube. The distal end of the first infusion tube has a tapered portion extending distally beyond a distal-most infusion aperture of the plurality of infusion apertures and to a terminal surface at a tip of the first infusion tube.

A conduit forming unit includes: a cylindrical tubular body having flanges, on both end portions of the cylindrical tubular body; a first connection tubular body and a second connection tubular body respectively connected to a first end portion and a second end portion of the cylindrical tubular body; and tube joints for connecting the cylindrical tubular body and the first connection tubular body and the second connection tubular body to each other. The tube joint includes: a pawl equipped nut where a plurality of pawl portions which are engageable with the flange of the cylindrical tubular body are formed in the pawl equipped nut, the pawl portions engage with the flange so as to connect the first connection tubular body and the cylindrical tubular body to each other; and a retaining ring being annularly mountable on the pawl equipped nut and retaining engagement of the pawl portions with the flange.

The present disclosure provides medical devices, systems and methods and in particular to devices and methods useful for anchoring graft materials to bodily structures.

Embodiments of the present invention provide an extra corporeal membrane oxygenation circuit, wherein a pump communicates blood from a patient to an oxygenator and thence back to the patient, comprising: (a) a medium diameter venous line configured to accept blood from the patient and communicate the blood to the pump; (b) a medium diameter arterial line configured to accept blood from the oxygenator and communicate the blood to the patient; (c) one or more shunts connected in a series, where each shunt comprises a medium diameter input connected to a medium diameter output, where the medium diameter output is configured to connect to a medium diameter input of a successive shunt; a small diameter outlet between the medium diameter input and the medium diameter output; and a stopcock connected to the small diameter output such that flow out of the small diameter outlet can be controlled by the stopcock; wherein a first of such shunts is connected to accept blood from the venous line in parallel with the pump and wherein a last of such shunts is connected to communicate blood to the arterial line.

An implantable system includes a ventricular assist device and a cuff for attachment to a heart. The ventricular assist device includes an inlet cannula. The cuff defines an opening for insertion of the inlet cannula into the opening. The cuff includes an annular fastening member and an attachment member. The annular fastening member is configured to be sutured to heart tissue. The attachment member includes flexible extensions. Each of the flexible extensions is configured to interface with the inlet cannula during insertion of the inlet cannula into the opening so as to cause the flexible extension to flex outward to accommodate passing of the inlet cannula along the opening. Each of the flexible extensions is configured to interface with the inlet cannula to impede extraction of the inlet cannula from the opening.
