Abstract: A coupling system includes an applicator tool and an attachment ring mounted on the applicator tool. Clips are contained within the applicator tool and are deployed through the attachment ring in order to anchor the attachment ring to biological tissue. When deployed, tips of the clips follow a curved trajectory through an annular cuff of the attachment ring and through the underlying tissue. The tips loop back out of the tissue and to a location where they are later trapped or clamped by the attachment ring. While the tips are trapped or clamped, the applicator tool cinches the clips by pulling rear segments of the clips. Thereafter, the applicator tool disconnects from the attachment ring which remains anchored to the tissue and serves as a coupling for a cannula. The cannula can have movable lock members that secure it to the attachment ring.

Abstract: In one general aspect, a cuff for attachment to a heart includes an attachment component configured to engage a blood pump to attach the cuff to the blood pump and a sewing ring for attachment to the heart. The sewing ring is coupled to the attachment component, and the attachment component and the sewing ring each define a central opening configured to admit an inflow cannula of a blood pump. The sewing ring comprises a member that provides rigidity to flatten a portion of a myocardium of the heart when the cuff is attached to the heart.

Abstract: Methods and apparatus for estimating flow rate in a blood circulation assist system employing impeller eccentricity. A method includes magnetically rotating an impeller within a blood flow channel of a blood pump. The impeller is levitated within the blood flow channel transverse to the impeller axis of rotation. A rotational speed for the impeller is determined. At least one impeller transverse position parameter is determined. The at least one impeller transverse position parameter is based on at least one of (1) an amount of a bearing current that is used to levitate the impeller transverse to the impeller axis of rotation, and (2) a position of the impeller within the blood flow channel transverse to the impeller axis of rotation. A flow rate of blood pumped by the blood pump is estimated based on the impeller rotational speed and the at least one impeller transverse position parameter.

Abstract: A catheter pump system is disclosed. The catheter pump system can include a shaft assembly and an impeller coupled with a distal portion of the shaft assembly. The catheter pump system can include a motor assembly, the motor assembly comprising a chamber and a shaft-driving portion disposed in the chamber. The shaft-driving portion can be configured to impart rotation to the impeller through the shaft assembly. The chamber can be filled with a gas that at least partially surrounds the shaft-driving portion. A fluid pathway can convey fluid proximally during operation of the catheter pump system. A bypass pathway can be in fluid communication with the fluid pathway, the bypass pathway configured to direct at least a portion of the fluid to bypass the chamber.

Abstract: In order to produce a pulsatile blood flow pattern that includes time periods of relatively high blood flow rates and time periods of relatively low blood flow rates, the operating speed of a blood pump can be selectively controlled to produce an operating speed pattern that includes time periods of relatively high rotation speeds and periods of relatively low rotation speeds. For example, the blood pump is rotated at a first speed for a first period of time. The speed of the blood pump is then decreased from the first speed to a second speed and is operated at the second speed for a second amount of time. The speed of the blood pump is then decreased to a third speed for a third amount of time. If desired, the operating speed pattern can be repeated to continue the pulsatile blood flow pattern.

Abstract: Methods, systems, and devices for an updatable blood pump are disclosed herein. The blood pump can be part of a mechanical circulatory support system that can include a system controller and the blood pump. The blood pump can include a rotary motor and a control unit that can communicate with the system controller. The system controller can initiate the update process and can provide the update to the blood pump. Upon initiation of the update process, the control unit can stop the rotary motor. While the rotary motor is stopped, the blood pump can be updated. At the completion of the update, the rotary pump can be restarted.
