Patent number: 11938311Abstract: A heart pump assembly includes an impeller blade coupled to a rotor or a drive shaft, a cannula, a distal projection coupled to a distal end of the cannula and a blood inlet having a plurality of apertures. The plurality of apertures is radially oriented and disposed about a circumference of the cannula. The plurality of apertures includes at least a first ring of apertures which are proximal to the distal projection and a second ring of apertures which are proximal of the first ring of apertures. The plurality of apertures can allow the heart pump assembly to continue to function if anatomical structures or tissue become suctioned to a portion of the heart pump.Type: GrantFiled: August 24, 2021Date of Patent: March 26, 2024Assignee: ABIOMED, INC.Inventors: Scott C.

Publication number: 20230157557Abstract: The systems, devices, and methods presented herein use a blood pump to obtain measurements of cardiac function. The system can quantify the functioning of the native heart by measuring certain parameters/signals such as aortic pressure or motor current, then calculate and display one or more cardiac parameters and heart function parameters, such as left ventricular pressure, left ventricular end diastolic pressure, or cardiac power output. These parameters provide valuable information to a user regarding current cardiac function, as well as positioning and function of the blood pump. In some embodiments, the system can act as a diagnostic and therapeutic tool.Type: ApplicationFiled: November 2, 2022Publication date: May 25, 2023Applicant: ABIOMED, Inc.Inventors: Christian Moyer, Scott C.

Publication number: 20230134031Abstract: A method for controlled purging of a blood pump and a blood pump assembly for implementing the method are provided. The blood pump is in fluid communication with a purging device. The purging device comprises a purge reservoir and a supplemental reservoir configured to be fluidically connected to the blood pump. The purge reservoir is configured to receive a purge fluid and the supplemental reservoir configured to receive a supplemental purge fluid. At least a portion of the blood pump is inserted into a patient and operated. A flow of the purge fluid is provided from the purge reservoir to the blood pump. A purge flow parameter at the blood pump is measured using a measuring device and when it is determined by a controller that the purge flow parameter meets a predetermined threshold, a remediation protocol is identified.Type: ApplicationFiled: October 28, 2022Publication date: May 4, 2023Applicant: ABIOMED, Inc.Inventors: Gary Stacey, Soumen Das, Scott C.

Publication number: 20230001178Abstract: A heart pump assembly having a blood inlet configured to increase blood flow into the heart pump assembly is disclosed herein. The heart pump assembly includes a motor housing, a cannula connected to the motor housing, and a blood inlet connected to the cannula. The blood inlet has a distal body portion, a proximal body portion defining an inlet conduit therewithin, and a plurality of cage openings defined and positioned between the distal and proximal body portions. The inlet conduit has one of a tapered portion, a frustrum-shaped portion, or both a tapered portion and a frustrum-shaped portion and is adapted to reduce flow turbulence at the blood inlet and increase the blood flow into the heart pump.Type: ApplicationFiled: June 29, 2022Publication date: January 5, 2023Applicant: ABIOMED, Inc.Inventors: Scott C.

Publication number: 20220313425Abstract: A polymeric heart valve is disclosed which includes a valve body having a central axis and including a conduit extending along the central axis from an inflow end to an outflow end; and at least three flexible leaflets extending from the body into the conduit, each of the leaflets defining an attachment curve with the body. Respective pairs of leaflets each define a commissure located proximal the body. The at least three leaflets define a partially open position at rest, a fully open position deflecting away from the central axis during forward blood flow along a direction from the inflow end to the outflow end, and a closed position deflecting toward the central axis during reverse blood flow along a direction from the outflow end to the inflow end.Type: ApplicationFiled: March 4, 2022Publication date: October 6, 2022Applicant: ABIOMED, INC.Inventors: Scott C.

Publication number: 20210339003Abstract: A method of operating a blood pump that is purged with a purge solution that contains a pH controlling and buffering agent combined with aqueous dextrose and a reduced amount of heparin or no heparin. The blood pump has a gap between a shaft and housing through which the purge solution flows. In operation, the purge solution exits the housing and is discharged into the patient. The purge solution is therefore required to perform lubricating and heat transfer functions in the pump yet be biocompatible with the patient.Type: ApplicationFiled: April 22, 2021Publication date: November 4, 2021Applicant: ABIOMED, Inc.Inventors: Soumen Das, Vladimir Gilman, Alexander Ship, Scott C.
