Dr. Leonard Golding, a former heart surgeon, is leading a team at
the Cleveland Clinic's Foundation developing a new LVAD called the CorAide. It
eliminates hemolysis and thrombosis problems by eliminating the seal and
reducing the pump to only three main components.
The pump's three components include a one-piece cast titanium
volute housing, a stator housing containing the motor windings, and a
cylindrical rotating assembly (the only moving part) containing a permanent
magnet and a set of impeller vanes on each axial end of the assembly.
The main pumping end of the rotating assembly has a primary
impeller, while the opposite end has a secondary impeller that allows a balance
of axial hydraulic forces. The configuration uses an inside-out motor along with
an inside-out radial bearing. The inside-out motor combines the magnetic drive
and bearing into one feature, and eliminates the need for a dynamic seal.
"The results in the animal model suggest that the CorAide pump
design is ready to begin pre-clinical qualification for use in humans," says
Dave Horvath, a mechanical engineer at the Cleveland Clinic Foundation who
helped design CorAide. For more information, contact Horvath at Cleveland Clinic

By refining topologies and using new fluid technology, Moog's new peak sine drive controller increases available power without increasing controller volume.
Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
