Related content reminds her of Cernik barney clark, curator of medicine and science at the National Museum of American History, who said, "A man with a large number of heart valves donated his unusual collection". This is my first time to hold "WOW" Jarvik 7 at the Smithsonian Institution. "Holding it is definitely * * *," she said.
Sernik said that through the gloves, Jarvik 7 felt "like a Tupperware". The two ventricles of an artificial heart are connected by Velcro, and this particularity "always makes people feel different, interesting and strange," she added.
Robert Jarvik, President and CEO of Jarvik Heart (founded in 1988). In the mid-1970s, researchers at the University of Utah invented and manufactured a total artificial heart. In addition to the artificial heart, Jarvik also invented the battery-sized Jarvik 2000 blood pump.
Thirty years ago this week, Cernik's special heart was transplanted into a patient. Michael drummond is an assistant manager of a grocery store in Phoenix. 1On August 29th, 985, this 25-year-old man became the sixth patient to undergo artificial heart surgery, and the youngest patient to undergo artificial heart surgery at that time. This is the first time to use a heart pump as a "bridge transplant" to prolong life until a human heart is found. Nine days later, drummond received a human heart. He lived for nearly five years,
(From left to right) Nina Trasov, richard smith, Mark levinson, Robert Jarvik, Michael drummond and Jack Copland announced at the press conference of 1985 that Jarvik 7 artificial heart was successfully used as a bridge for transplantation for the first time. (? 1985 Arizona Regent's Committee/University of Arizona Health Science Bionewsletter) "KDSP" As the anniversary of heart transplantation approaches, the American Museum of History recently received a donation from Tucson University. Two modern hearts in Cynthia, Arizona-a Cynthia 70 ml total artificial heart and a Cynthia 50 ml total artificial heart, and a 70 ml model slice-let visitors see the inside of the ventricle-a backpack. The latter is outside the body and provides energy for the heart. Jarvik 1977, a famous prototype of artificial heart, is currently on display in the museum's new exhibition "Invented in America", which is organized in cooperation with the US Patent and Trademark Office. A SynCardia 70cc total artificial heart (left) and a SynCardia 50cc total artificial heart (SynCardia Systems,1967 65438+On February 3rd, South African surgeon Christiaan Barnard performed the first successful human heart transplant in Louis Wash Kanski; The patient, the owner of a grocery store in Cape Town, lived 18 days. Nearly 15 years later, surgeon William Defrees implanted Jarvik 7 artificial heart in barney clark, a dentist in the University of Utah Hospital, on February 2, 1982. Clark lived 1 12 days, which was the first time that a permanent artificial heart was implanted in a patient. Jarvik 7, accepted by drummond nearly three years later, is the first time in history to authorize the successful transplantation of artificial heart into human heart. The word "authorization" is also very important, because another 1969 artificial heart transplant is still shrouded in controversy; The patient lived less than two days after transplantation. According to * * *, the tension between doctors who have cooperated in this technology is "the most famous feud in the medical field-of course, it has the longest life."
1June 38, 979, 165438+ 131October, Robert Jarvik's "totally artificial heart and heart auxiliary device driven and controlled by reversible electro-hydraulic energy converter" was patented. (USPTO) "KDSP" The artificial heart obtained by drummond is the product of the first kolff medical company (Robert Jarvik is CEO); 1983 changed its name to Symbion；; 1990 FDA closed Symbion (because it violated FDA guidelines and regulations) and transferred its artificial heart technology to CardioWest；; 200 1, the company became SynCardia. Craig Selzman said that after 30 years of heart treatment in drummond, the artificial heart hasn't changed much. Barney clark, director of cardiothoracic surgery at the University of Utah, was the site of the 1982 transplant.
"Interestingly, Jarvik 7 is very similar to the FDA-approved Total Artificial Heart (TAH), which is now owned by SynCardia," Selzman said. "Of course, there have been some improvements in the past 30 years, but it is very similar in function to the equipment received by barney clark and Michael drummond." Despite the efforts of the National Institutes of Health to promote the development of this field, "Jarvik-7 is still the basic design on the shelves today," he added.
Artificial hearts and other cultural relics found in medical collections of museums are donated by enterprises, institutions, medical facilities and families because of their historical significance. (Jarvik 7 from drummond was later donated by the University of Arizona Medical Center to the Smithsonian College, where his operation was performed. )
"Sometimes there are uncomfortable factors, but you will get a lot from our collection," Cernik said. However, she added that most tourists who saw artificial hearts in exhibitions and educational programs were fascinated by them. She said: "Many people are in awe that this mechanical device can be implanted into the human body to replace the original heart." . In * * *, the museum staff blew air into the ventricle (through a tube), causing the diaphragm to contract and expand.
Selz Mann believes that it is very important for students in this field to keep the history of heart transplantation and provide future generations with "the motivation to innovate for our patients"
"The history of heart transplantation developing mechanical support for these heart patients is one of the most fascinating stories in all medical fields," he admitted. But it contains intrigue, personality conflicts and pioneers greater than life, involving engineering, surgery, medicine and, of course, brave patients. I challenge you to find more spelling stories than this field.
The recently donated new heart can be watched at Wallace H. Kurt Performance Square in the National Museum of American History at 1 1 and 2: 30 am on Tuesday, Wednesday and Saturday, announcing "How to repair a broken heart?"
