Implantable Left Ventricular Assist Devices

New England Journal of Medicine, 1998
Congestive heart failure affects about 1 percent of adults in the United States1 and is a contributing factor in over 250,000 deaths annually.2 It is diagnosed in 400,000 Americans each year3 and is the primary diagnosis for over 900,000 hospitalizations per year.4 In 1990 the age-adjusted death rate from congestive heart failure was 106.4 per 100,000 ...

Development of Totally Implantable Pulsatile Biventricular Assist Device

Artificial Organs, 2003
Abstract: Approximately 10% to 15% of all patients implanted with left ventricular assist devices (LVADs) have required right heart support with another device. The necessity of aggressive biventricular support has already been proposed. Therefore, the totally implantable biventricular assist device (BVAD) was developed. The width of the BVAD main body

An Implantable Umbo Microphone For Fully-Implantable Assistive Hearing Devices

2021 IEEE Sensors, 2021
This paper presents an implantable microphone for sensing the displacement of the umbo, the end of the malleus where it attaches to the center tip of the cone-shaped tympanic membrane. The sensor comprises a piezoelectric polyvinylidene fluoride (PVDF) film with copper-nickel electrodes suspended across a brass cylinder.

Implantation of the Left Ventricular Assist Device

Journal of Cardiac Surgery, 1987
Development of mechanical devices for support of the failing heart is a major goal in cardiac surgery. The application of left ventricular assist device (LVAD) is a promising approach in the case of severe and otherwise untreatable cardiac failure.

Minimally Invasive Implantation of Biventricular Assist Devices

The Thoracic and Cardiovascular Surgeon, 2014
As minimally invasive left ventricular assist device implantation is being advocated and more widely performed, bailout strategies for postoperative right ventricular failure (RVF) become necessary. We describe our surgical technique for additional right ventricular assist device implantation through a third mini-thoracotomy incision.
