LOUISVILLE Colorado- Tensegrity Prosthetics Inc.
in Louisville has received a two-year $750,000 grant to continue the
redesign and manufacture of prototypes of a flexible prosthetic foot.
Jerome Rifkin, founder of Tensegrity Prosthetics, said he will
receive $415,000 of the Small Business Innovation Research grant from
the National Institutes of Health the first year.
He plans to spend the money on finishing the redesign of the
prosthetic foot and then create small and large batches of prototypes
for testing.
"I hope to be able to stabilize the product, increasing the
efficiency and decreasing the number of falls incurred by amputees
using current prototypes," he said. The prosthetic foot mimics the
biomechanics of the human foot. Tests show it requires less energy to
use, and amputees testing the beta version report more comfort and
agility when walking.
The prosthetic is made of titanium, aircraft aluminum and
steel-fiber rope. It bends like the normal foot and ankle, conforming
to the terrain under foot, while providing a sense of being
well-connected to the ground.
In 2005, Rifkin received a two-year, $200,000 SBIR grant from the
NIH for research and has raised another $150,000 in venture backing.
He has received positive feedback from amputees who have
participated in clinical tests of earlier prototypes, but the
prosthetic's durability is still the challenge.
"Before I can begin manufacturing these, they need to be able to
last for at least two years," he told the Boulder County Business
Report in August. The durability problem is caused mainly because the
prosthetic (foot) is so flexible, the very attribute that makes it appealing
to amputees.
Rifkin received an IQ Award in August from the Business Report for his innovation.
