Dr. Saad Saad is an accomplished pediatric surgeon who has performed thousands of pediatric surgical operations during his career. As a physician, Dr. Saad was always seeking to improve existing methods and procedures. He was constantly challenging the status quo to find ways to reduce pain and the risk his patients faced. As a result, he has patented two inventions and developed many new pediatric surgical procedures. For more than 40 years, he performed complex pediatric surgeries on patients both inside and outside of his community. Dr. Saad served his community in the United States but also helped children and young adults in the Holyland, to include four Medical Missions in the US and eight Medical Missions to Jerusalem and the West Bank to perform free complex surgeries on poor children. Dr. Saad personally holds the patents for both of his medical inventions.
Catheter with Integral Electromagnetic Location Identification Device (Patent Number 5,727,553)
Medical catheters are tubes which can serve a broad range of functions. Specifically, they are tubes which are inserted into the body to treat medical conditions or help perform a surgical procedure. They can provide access to surgical instruments, drain gases and fluids, as well as other tasks depending on the type of catheter. Certain catheters can be left inside the body, whether temporarily or permanently.
In order for a catheter to be put in the right location inside the body, surgeons have to be able to easily track its exact position. Traditionally, to see exactly where the catheter has been placed an X-ray is being performed . However, while a single X-ray does not put you at any significant risk of illness, frequent X-rays still expose you to repeat doses of radiation. Alternatively, you can have an MRI ( Magnetic Resonance Imaging ) performed instead of an X-ray to track the catheter. But MRI machines are large and not portable, making them an impractical alternative option.
That is why Dr. Saad decided to create a device that helps locate the catheter without any kind of machine scan of the patient’s body.
The catheter with integral electromagnetic location identification device works by utilizing electromagnetic energy to figure out the location of the catheter. The catheter tip itself houses magnetically permeable material inside the coil and the catheter has a pair of wires inside its walls. This allows the doctor to use an external locating device to scan the outside of the patient’s body that it sends signals to the coil and the magnetically permeable material Once the external device is over the catheter and is perpendicular to the catheter’s tip, an output voltage is created which passes through the wires to illuminate the light in the external locating device, letting the doctor know that the external locating device is directly over the catheter.
By comparison, this medical device works like a metal detector. The user of a metal detector can use it to sweep the ground to find metal located beneath. Similarly, a doctor can sweep the outside of a patient’s body until the tip of the catheter is located and the external locating device is perpendicular to the catheter.
Dr. Saad’s invention allows patients to avoid X-rays and MRI scans to locate the catheter. This device is small, portable, and practical, allowing doctors to use it in the ICU in case of emergencies when there may not be time to perform a body scan to find the catheter. It also allows doctors to avoid using guide wires to track the placement of the catheter when the catheter is first inserted inside the patient. These guide wires can break and get stuck inside the patient, which is potentially hazardous.
Unfortunately, Dr. Saad’s catheter invention as described above has not yet been implemented to be widely used. The manufacturing of the catheter invention requires complicated procedures, discouraging manufacturers from making it. However, a large medical company in Utah has shown interest in the catheter invention device, so it is likely that the device will be used by doctors in the future. After all, it is a practical solution that makes life easier for doctors and keeps the patients safe.
Methods and Apparatus for Providing Suction and/or Irrigation in a Rigid Endoscope While Maintaining Visual Contact with a Target Area Through the Endoscope (Patent Number 5,725,478)
Dr. Saad’s second invention is meant to improve the use of endoscopes. Endoscopes are optical devices that are used to look inside the patient’s body during an examination or surgery. Endoscopes can be used to look inside the throat, the windpipe , even the bladder, stomach , and colon. These can be extremely useful in providing the doctor with a visual picture of what is going on inside the patient’s body without surgery or performing a body scan.
Our body produces full of liquids on the inside which can pose problems to endoscopes. These liquids can fog up the lens of the endoscope, obstructing the view of the doctor looking through it. To avoid this, the endoscopes anti-fog port is being converted into suction-irrigation device to clear up the view. Without the invention of suction-irrigation device the body liquids will obstruct the view. In this situation the endoscope has to be taken out and a suction tube has to be inserted in order to vacuum away the liquid. After the suction is performed, the endoscope has to be reinserted and the doctor has to find where they were at previously.
Dr. Sad’s invention addresses the above problem . The endoscopes that are used for bronchoscopy (looking at the lungs), esophagoscopy (looking at the esophagus), and sigmoidoscopy (looking at the large intestine) are being fitted with above device invention . The doctor looking through the endoscope can use this device to suck away any liquid that is hindering their view without having to remove the endoscope and the irrigation allows the doctor to pour fluid to clear the view and wash the area in front of the scope before sucking the fluid back to give clear view for the doctor during the endoscopy procedure .
Dr. Saad personally attests to the useful features of this device. He has performed thousands of endoscopies during his career as a pediatric surgeon, helping remove any foreign bodies such as marbles, needles, stuck food, or whatever else a child may have swallowed or inhaled , from their body. Moving the endoscope and having to readjust the focal point when looking through the scope again can add significant time to the procedure. But Dr. Saad’s suction device makes the procedure easier because the doctor never has to move their eye away from the scope.
Because the suction and irrigation device is practical and is cheap to make, this invention is frequently used by doctors today. Like above mentioned, Dr. Saad has personally used this device on his patients with much success.
Necessity is the Mother of Invention
When asked why Dr. Saad decided to invent these two devices, Dr. Saad simply answered that “necessity is the mother of invention.” Both of his devices help doctors perform their tasks in a safer and more practical manner. By avoiding body scans and using a guide wire with an external locating device, and by avoiding having to take out the scope during an endoscopy, Dr. Saad’s inventions allow doctors to prevent needless complications and perform their tasks in a faster, safe manner.
Technology in the medical industry is constantly changing. Making the lives of doctors easier while keeping the patients safer is a win-win for Dr. Saad. It is great that he has used his personal experience to not only perform his duties as a surgeon, but to also create innovative devices that will only further revolutionize health care.
