Best Pacemaker?

Hi,

My brother needs a pacemaker for a bradycardia problem (heart rhythm too low). The doctor proposed the implantation of a pacemaker produced by a company called Sorin Group; I've searched on the web for information about this company and if their products can be considered "the best abailable" on the market. I know that they are FDA approved so they're safe, however given that it must be put in my brother's body for lot of time (hopefully long time...) I'd like to see also other opinion/experiences/etc...

Thanks

Angelo
