Imagine going about life when all of the sudden you develop the worst headache of your life, or one side of your body suddenly becomes weak. This innovation was first published by the University of California San Diego Jacobs School of Engineering on August 20, 2021. The steerable catheter was created with one goal: to save more lives. Hastings (2021), stated that this new catheter technology can possibly allow physicians to reach tiny vessels in the brain that are currently unreachable. With this device, brain aneurysms that were once deemed terminal can now be treated. According to Patringenaru (2021), This new technology will enable surgeons to guide the wire with greater precision through small vessels once deemed impossible to access. With so many blood vessels in the brain being tiny and inaccessible, this new innovation has the potential of saving countless lives if successful. Patringenaru (2021) stated that the engineers of this device drew their inspiration for the design from flagella and insects. If successful, this technology will revolutionize the treatment of strokes and brain aneurysms as we know them.
     Currently, clots that are causing occlusion in the brain can only be retrieved if they are in large vessels, i.e. middle cerebral arteries, basilar arteries, carotids, vertebral arteries, etc. They are retrieved with a guidewire that is advanced through the femoral artery. Even though it is amazing technology, according to J. Belami et. al. (2018), complications such as puncturing the artery and causing possible catastrophic bleeding are risks. According to Hastings (2021), this new technology can actually be advanced with a controller and is so small that it not only can it go through small and large vessels but has a much smaller risk of complications.

  • Small and easier to manipulate.
  • It can travel to tiny and tortuous vessels once deemed unreachable.
  • Potential of saving thousands or even millions more lives.
  • The femoral artery does not have to be punctured every time.
  • It can be manipulated with a controller and not a guidewire.
  • Imagine something as tiny as hair going through blood vessels and fixing aneurysms and retrieving clots.
  • Less risk of puncturing through blood vessels.
  • Less help and resources required in interventional radiology suite

  • What happens if it gets stuck in the blood vessel?
  • Controller malfunction.
  • Blood vessels are tiny (some the size of human hair) and are very difficult to access.
  • The learning curve with using handheld controller versus guidewire.
  • Still requires many human trials.
  • Uncertainty of deviating away from what has been tested and proven.
  • Cost of the new device?

It blows my mind that it may be possible to reach even the tiniest vessels of the brain once deemed unreachable. Imagine being able to save thousands, even millions more lives one day in the future. If this technology can make it and successfully pass human trials, the future of neurological and neurosurgical medicine looks very bright. 
         In conclusion, it appears as though the benefits outweigh the risks. This still has to pass human trials, so we will have to see what the future holds. As someone who has many years of experience in the Neurological ICU, I have seen countless clot retrievals and aneurysm coilings, and both the benefits and harm patients have suffered from them. I have high hopes that one day this technology will be perfected, and we will see neurosurgical medicine revolutionized. Fixing aneurysms and clots within the brain does not come without incredible risks. The human brain is such an incredible yet fragile organ when compromised. It would be incredible if one day so many more people could live a life without debilitating complications and deficits due to strokes and aneurysms. I have high hopes for the future of this device and the exponential change it could make on modern medicine.]]>     2022-09-12 17:40:17 UTC https://padlet.com/lindseyasmith94/m347oe1p77dz07zy/wish/2292844053     lindseyasmith94 https://padlet.com/lindseyasmith94/m347oe1p77dz07zy/wish/2292863989 Tortuous Blood Vessels]]> 2022-09-12 17:51:06 UTC https://padlet.com/lindseyasmith94/m347oe1p77dz07zy/wish/2292863989 lindseyasmith94 https://padlet.com/lindseyasmith94/m347oe1p77dz07zy/wish/2292871137 2022-09-12 17:54:56 UTC https://padlet.com/lindseyasmith94/m347oe1p77dz07zy/wish/2292871137 lindseyasmith94 https://padlet.com/lindseyasmith94/m347oe1p77dz07zy/wish/2292881524 2022-09-12 18:00:46 UTC https://padlet.com/lindseyasmith94/m347oe1p77dz07zy/wish/2292881524 References lindseyasmith94 https://padlet.com/lindseyasmith94/m347oe1p77dz07zy/wish/2292893444 Patringenaru, I.

    • Achiever. This will help the team because I am a hard worker and like to finish whatever I start. I will strive to accomplish whatever task is given to me and see the evaluation and possible implementation of this device all the way to the end. I believe in starting what you finish, and will push the team to do the same.
    • Consistency. I believe in treating everyone the same and with respect no matter what their role is. When it comes to the evaluation of the new device, it is important that everyone is given a clear role and treated with respect. By being consistent and fair, I will hope to motivate the team to work hard and feel like they can accomplish anything.
    • Futuristic. Being futuristic will help motivate and inspire the team in what this new device could mean for the future of medicine. Also, not engaging in or bringing about conflict will help the team stay focused on the task at hand and not distract from the importance of seeing that this device is evaluated properly.
    • Learner. By being a learner, I will help the team see the importance of this new device and how learning about new technology can possibly save so many lives. I will be enthusiastic about evaluating the new technology and hopefully, the enthusiasm will translate over to the rest of the team. 
    • Positivity. I do like to think of myself as a very positive person and want the enthusiasm to spill over to everyone else. A negative and nonchalant attitude can bring down morale and make people not want to engage or be excited about the project. With my positivity and enthusiasm, I want the rest of the team to feed off the energy and be inspired by the innovation.
