Small Battery Size - Latest Development

Any news of development of smaller batteries and if so when are they likely to be implemented - Thanks

Haven’t heard a thing about smaller batteries! With my HM3 I get close to 17 hrs a day. Would much rather have them concentrating on how to make this system waterproof. Would be nice to get back in a pool again and not go through the change of life to take my daily morning shower!

I've heard that the total implantation-2 years off...Haven't heard smaller batteries as of yet.  Amen to your comment Larry B with swimming etc,/bathing.  I've been an avid swimmer all my life.

I don't know if you saw the news a few weeks ago.  The FDA has given Medtronic fast track approval to develop a completely implantable LVAD including the power source. N it's a few years from going to market but it is coming. Medtronics is working on it and predicts in 2 to 5 years it could be ready for wide distribution.

 

An LVAD with no DRIVELINE. No more infection risk, and since it's all internal, no  more bandages to change. Essentially a heart transplant without the risk of infection or rejection.

 

Not sure if I want to do the surgery again just to get that,  but if my pump was having issues this would be a great upgrade

I would surmise the 5 year point....They need to make their $ on the HM3....... Its dollars and change!! Bottom line....and going through open heart surgery more than once, well is too much for me! The thought just irritates me internally.  I continue to pray that my heart improves, EF that is, and I can get this unhooked...

Yes that is what Jefferson told me it is about 2 years off, the total implantable.  I am curious though how big the entire unit is?  Basically, as I was told, what is on outside, will be put inside.  and claimed would be more chance for infection.  The reason they didn't have them as of yet because the trials, they were catching fire inside...Just sharing.  I would love nothing more to have it out of implantable to live a normal life.  I'll wait, of course we all will, until the perfect this unit.  Thank you for sharing!!

We all need to send ELON MUSK money to invest in long term batteries, because that's really what's needed. They can shrink the controller down, and transmit data to doctors via blue tooth, so the true limitation is battery life.

 

Maybe you have to go in every once in awhile for new batteries?

use wide masking tape for showering.   It works great.  Keeps site dry and removes easily.

My husband his destination HM2 surgery in oct. 2016.  He had to have a replacement 5 days later , Thrombosis on the pump.  He was in the hospital 61 days.  His age is 74.  There has been some events due to the Lvad, but nothing basically faulty with it.  He recently had an alarm go off and he stopped breathing , was unconscious for 1 minute. His pump stopped and there was no blood being pumped.   I am his wife and caregiver, very scary.  Did the steps, called the team, he did come back to me.  He was hospitalized at Mayo in Pheonix , for what they call “short to shield “.  They preformed an external percutaneous lead replacement , this did not solve the problem ,when returned to grounded cable.  He was discharged with a power module and a non-grounded cable.  We will be replacing his pump again due to continued wiring damage progression. 

I, Susan would like to know if any other Lvad patient has experienced this.

Susan I have had the same experience with a short to wire. I am an electrical Eng so a lot of questions were asked and answered. Short tutorial--The drive line consists of 6 wires or 3 pairs each pair is capable of supplying power to the pump. they are wired in parallel. this allows for triple redundancy for a wire breakage. these 6 wires are enclosed in a grounding tube made like a hollow rope made of hundreds of hair thin wires. what happened to me and your husband was that one or more of the ground part broke and became like little needles that penetrated at least one of the power carrying wires. Mine was detected in clinic when I switched from battery to cable and alarms started going off. They switched me to an orange coded cable that was ungrounded and solve the immediate problem. I was then given an "orange cable to take home. they set up an appointment with two of the Abbott Labs engineers to do the cut and replace wire by wire routine on me. I felt like I had a bomb in me and two bomb tecs were defusing me. 

I hope this helps you understand the situation better. I think Heartmate III do not have a ground cable part. It maybe the Heartware one that have a clear drive line and you can see the 6 wires. Lucky for me the short was in the part of the drive line that was outside my body so no surgery to replace the line. The surgery required if it was inside would be done under the rib cage and not requiring the chest to be cracked open.

I was also told, for your FYI, pig hearts would be used before implantable was done...Idk..just sharing!!

How do you handle your LVAD at the airport with regard to the metal detector or wanding?  

The same question please for major sporting events where there are metal detectors.

I have not had to address the issue with metal detectors, wanding, etc. yet.  However, my LVAD team explained that if you suspect it could happen to arrive early, give them the security letter I always carry, advise security what you have and the circumstances, and to request a manual inspection by proper security personnel.

Have a Heart Mate 3 and have been advised not to take the chance, do any electrical work, welding, or even lean over into an engine compartment as they are not sure what exactly could happen.  No ID card just a letter from LVAD department addressed "To Whom It May Concern" with their 24 hours contact number if further information is needed.

I've had an LVAD for five years now and have been through metal detectors at sporting events, airports, foreign travel, and other types of events. Tell security you have an LVAD and they will wand you by hand. There is no danger to your LVAD (no magnets involved) and no note or card required. Sometimes it takes a little longer, waiting for a person with a wand to show up, but sometimes you can go through faster, too.

I refuse to allow them to wand me or scan me in any way as a magnetic field can stop your pump. I quickly volunteer for a personal pat down. Now I call ahead and ask for the senior TAS agent on duty for the time and flight that concerns me. I have a Doctors letter explaining my condition with the doctor personal cell number. The bigger problem is forcing them to allow you to take all your equipment on board as carry on. Checked baggage may not arrive at and when you do, if ever. I have a hard case bag that is the largest allowed carry on. It took me hours to figure out how to position everything just perfectly so that it still close. I even took pictures so that I could repeat it.

Most sporting events only have walk thrus that are similar to a retail store so the power is not that strong. They are OK, but don not linger in them. If you are pulled aside for a hand held scan refuse and explain situation allowing the physical pat down.

I am a  100 lb women who find the batteries very heavy I would be so happy if they made A lot lighter battery so I can walk longer and do more things

A lot depends on how you carry and distribute the weigh. Don't tell me your purse is under 7 lbs girl. I am a male but have studed all different kinds of ways to carry the equipment. For women the best thing I have found on the market is a thing called runtasty. I know the name is strange, but it is designed for joggers or runners. It has two pouches for water bottles which with a small modification can accommodate the batteries with an elastic band holding them in. The modification is one snip and then you can use the elastic as not intended. The controller will fit in the clear pocket designed for the cell phone. Janette, which is the same as my sister (actually just close, her's is Jeanette), if this is totally confusing to you please contact me at jeffwillcox@comcast.net or any body else.

   Hi , I've read it on this website and my support nurse told me the same thing. I don't know how long it will be but I heard this. HONEST !!! I would not tell you this  if it's not true. You take care and Peace be with you.

Yes,  I'v heard it was a couple, to three years off...However, I've also heard from various Dr's that what is on the outside will be inside...I can't imagine having this huge battery pack and controller inside of me...infection city.  They would need something smaller, compact, while securing this development.  Don't get me wrong...they should have had something a long time ago; however, with a patene they always run the entire time to make the $$$$.

  This is just my feeling, my husband last year in November had a LVAD malfunction.  It was called short to shield, basically wiring , inside.  So he had surgery for new implant in December, four weeks later back in the hospital for infection, 5 operations in 10 days for debridement, application wound vac, irrigation chest, reconstruction chest wall and evacuation hematoma.  This was a very difficult time for my husband.  It was more painful and stressful than his first implant 3 1/2 years ago.  Hey, he’s alive and recovering, the docs, the nurses and the team were amazing, but my husband is 74 yrs. old and I think this is good.   It’s amazing what could be changing for those that need it.  
God Bless us all, save us from the virus😇

Wow, Susan, my heart goes out to you and your husband.  What a fighter he is.  I had a little taste of driveline repair, alarms...However, the update on the software wasn't done for the new controller, therefore, it was off balance and didn't match.  My driveline was little severed and had to be repaired..Now I have a heavy inch/and a half hard type tube over it....Very balky!! What an experience as well, but nothing like your husband's.  Hope all is going smooth for you and God be with both of you...

My husband, age 78,  had a similar occurrence although not as bad as the two of you suffered through.  It was a short to shield issue which must be fairly common.  And external repair was attempted but it was determined the problem was internal so he underwent a pump exchange.  Sadly to say it was almost a case of, "the operation was a success but the patient died"...almost.  On the 3rd post op day he bled out 2 units of blood from the old exit wound.  The wound was packed.  He was transfused and 3 months later he had a driveline infection.  This could be credited to not the short to shield problem but the blood loss post op which in my opinion was preventable.  He had 6 weeks of daily IV antibiotics and has been on a daily maintenance dose for the last 2 years.  Fortunately he has been able to be active and feels very well.  Hang in there.  It will all get better.

Thank you for you reply. This type of connection with other LVAD patients really helps.  Barry’s recovery has been a journey of different conflicts, and now with Covid-19 , continued concerns.  His breathing is very difficult, he is still very weak, and he is one that has a hard time with therapy.  We have in home therapy coming in 2Xs a week, but he should follow up with time at home exercise that they have suggested.   I don’t push him, he already has enough to deal with.  I just say my prayers that it just takes time, give him the strength he needs.

God Bless be safe, Susan

My husband has a Heartmate 3 installed 8/16 2019.  We were given a letter for TSA but in addition 72 hours before our flight we called TSA Cares & gave them my husband's information.  They will contact your departing airport and set it up.  We were also advised to order a wheel chair in advance which helps going through security & boarding the airplane. On our originating flight we were met at the ticket counter by  a TSA agent who walked us through the process.  They did not use the wand directly but had my husband rub his hand over his control unit & batteries & then used the wand on his hand. We had no problem getting our hard carryon bag full of the LVAD equipment through security.  Be sure not to put anything but the equipment in the case and label it on the outside MEDICAL EQUIPMENT. It is not counted as one of your carryon bags and they will not try to get you to gate check it.  Prior to our return trip my husband had lost his wallet so when I contacted TSA Cares 72 hours ahead they told me what to do and said don't worry we'll get you on the flight.  It took a few extra steps, but we got thru security just fine.
