Your best bet has got to be to talk to your supervising physician or the manufacturer of the device - no-one else is really going to be able to say if your condition & the way the device operates will make it safe to drive or even possible to remain alert & in control of your faculties while it's doing whatever it hasta do to keep you alive; & please bear in mind that it's not only yourself that you might be putting at risk either, you've also gotta consider the other road users out there who might end up on the wrong end (possibly terminal!) of your failure to remain in control of your Spyder while the device does it's thing!! :shocked:
You can't just assume what this vest (or the implantable device for that matter) will mean to how you live the rest of your life, but I'm pretty sure that if you tell your Doctors how important getting out on your Spyder is to you & your lifestyle, they will make every endeavour to make it possible for you to continue ryding! I am just a month on from surviving a heart/lung event that apparently very few survive, let alone walk away from; but after making sure my Doctors knew how important continuing Spyder ryding was to me, when I was discharged they collectively agreed (& documented!) that I was well enough to ryde & not a significantly greater risk to other road users than any other licenced driver and they have approved my continuing to ryde & to drive too, as (at least here in Aust) many heart incidents &/or surgeries/appliance installations etc mean mandated periods of No Driving & the consequent suspension of your licence, with various degrees of approval & testing required before re-issue of your licence. So I was extremely lucky on so many levels; I survived AND I'm allowed to continue driving/ryding too!
It might be prudent to make sure that your State doesn't have similar No Drive periods or requirements for approval &/or re-testing before returning to driving!! It'd be a pain to get booked for driving on a medically suspended licence just because you weren't aware that it was a mandatory suspension following your heart event or for wearing that vest; or even worse, having a prang when you shouldn't have been driving for those or any other medical reasons & injuring (or killing) an innocent by-stander or any other road user!! :yikes:
So whatever you do & whatever other info/advice you get given here, before heading off to collect your Spyder, it'd be smart to make sure you talk to your Doctors & your driving licence issuers about this sort of stuff & make sure that you are cleared & OK to drive/ryde both medically & legally! :thumbup:
Edit/ps: sorry, but I took a long time typing my saga! Please Add my 'aye' to that earlier advice. And all the best for your recovery too - just remember that heart problems are just another challenge to overcome; if you are still here to face & overcome them, you are more'n half way there already!!
