Battery issue of a Pacemaker, KDR901
A friend of mine in China is currently using a Implantable Pacemaker-Kappa, model KDR901 from Medtronic. It was bought via an agent one year ago. However, the battery in it seems not working well and shows low voltage number (2.6 v). The local Medtronic office in Shanghai did not provide a good service in explaining it in details. They suggested to buy a new one. It costs US$10,000 in China for a new one. Obviously this cost is way too high for a low income family. My friend will have to have a heat surgury next Wednesday. He does'nt know what happens to his pacemaker and if he need a new one. I will appreciate it if very much if anybody can help me with the questions below:
1. what is the initial output voltage of the battery?
2. what is the lifetime of such a battery normally?
3. what is a low output limit of the battery to function?
4. if the battery voltage is too low to work, can we find a
replacement or we have to get a new Pacemaker?
