Title: Heart Failure is a progressive disorder
1Heart Failure
- Heart Failure is a progressive disorder
- Characterized by an enlarged heart with a
decreased ability to pump blood. - Enlargement leads to progressive structural and
functional changes (ventricular remodeling) - Heart size predicts mortality in heart failure
patients
Affects 5 million people in the US and 25 million
people worldwide. 550,000 new cases diagnosed
each year in US
2Heart Failure Treatment Options

3CorCap Cardiac Support Device
- The CorCap is designed to
- Provide end-diastolic ventricular support to
reduce wall stress and myocardial stretch - Negate the stimuli for ventricular remodeling and
promote myocardial reverse remodeling - Reverse progressive dilation and improve cardiac
function and patient functional status
4CorCap Cardiac Support Device
- Multi-Filament Yarn / Knit Fabric
- 4 Key Design Features
- Optimal compliance - stretchiness
- Bi-directional Properties
- Reshapes the heart to ellipsoid
- 31 micro fiber construction
- Smooth fit on surface of heart
- Long term biocompatibility
- Materials used in other implantable devices
