Dr. Manwaring was especially happy.
It was his technology that helped save Ricky's life.
Manwaring is not only a doctor. He is also an inventor.
He built a laboratory in his house.
Here he invents medical tools.
He has invented five important tools.
One of these tools helped to save Ricky's life.
This tool is called the microneedle.
It is long and thin. But the end of it is the size of one molecule.
This small tool is very exact.
It causes less bleeding and damage than a bigger tool.
This microneedle uses electric charges to cut through body skin, tissue and muscle.
It is also perfect for cutting around nerves.
Doctors used this needle on Ricky.
So Ricky did not bleed very much--and his body healed faster.
Ricky got better much quicker because of Dr. Manwaring's microneedle.
A year later Ricky was still healing.
By then he was in high school.
He still could not move his left arm.
At night he needed a machine to help him breathe.
But he was able to climb steps and to run.
Many people called Ricky the 'Miracle Boy'.
Ricky was very thankful for his life.
A television reporter asked Ricky what he learned about life from his experience. He told her:
"I learned that you only have one life. And that there is a God."
"I am here. I am alive. I am happy with that."
Ricky's thankfulness has helped him to be happy.
He refused to let his accident stop him from living a normal life.
In fact Ricky wants to work with other people that have injuries to their backbones.
He wants to offer encouragement. He said:
"I would say to others do not give up. Continue.
Take times of sadness and anger, and turn them into willpower to continue."
