Cheney, in a speech at the National Press Club in Washington Tuesday, said the tax on medical devices also demonstrates how "ill-conceived" parts of the Affordable Care Act really are, ABC News reported.
"I think that's one of the dumbest ideas I've heard," Cheney said of the tax. "I feel very strongly about it. I'm literally walking around proof of how great and how innovative our healthcare system has been. ...
"But I just think it's an example of how ill-conceived parts of this program are."
Cheney has had five heart attacks and has had several procedures to treat heart disease, including a heart transplant in 2012.
Although he panned the device tax and expressed concern people might not be able to keep their health insurance under the Affordable Care Act, Cheney -- for the most part -- avoided criticism of the entire healthcare law.
"There was a time in my life when I was about 23, shortly before we got married when I was sick, hospitalized and uninsured," Cheney said. "I spent our honeymoon money on medical bills. Later on, I learned that I needed health insurance."
