They didn’t exactly say no, they just said they want more data. It might not be that crazy not to rush things with a patient that needs re-implantation when you’re trying to test the next revision of the implant and have willing patient who only requires an initial implantation.

As long as these patients are properly informed on the risks and limitations of this experimental tech, I don’t see a problem. There’s no evidence that they are treating their patients badly, or failing to fulfill any promises in regards to the efficacy of the implants, or commitment to support these early test implants insofar as they agreed to provide to their patients (to my understanding, they are informed that the implant could be a total failure with no opportunities to re-implant.).
