Publication number: 20240415399Abstract: The systems, devices, and methods presented herein use a heart pump to obtain measurements of cardiovascular function. The heart pumps described herein can operate in parallel with and unload the heart. The system can quantify the functioning of the native heart by measuring certain parameters/signals such as pressure or motor current, then calculate and display one or more metrics of cardiovascular function. These metrics, such as left ventricular end diastolic pressure (LVEDP), left ventricular pressure, and contractility, provide valuable information to a user regarding a patient's state of heart function and recovery.Type: ApplicationFiled: April 17, 2024Publication date: December 19, 2024Applicants: ABIOMED, Inc., Massachusetts Institute of TechnologyInventors: Elazer Edelman, Brian Chang, Noam Josephy, Sonya Sanat Bhavsar

Publication number: 20080316698Abstract: A damping structure for electronic devices has a holding rack mounted onto a chassis to hold an electronic device. The holding rack has two ends extended towards the chassis to form respectively a step portion and a first coupling section extended from the step portion. The holding rack has two other ends extended sideward to form second coupling sections to form a holding space for the electronic device. There are damping assemblies interposed between the holding rack and the chassis, and between the holding rack and the electronic device. The damping assemblies are independent and can provide elastic damping forces.Type: ApplicationFiled: June 25, 2007Publication date: December 25, 2008Inventors: Fun-Son Yeh, Brian Chang
