Now there's a patent, but University of Utah researchers are waiting on Federal Drug Administration approval before implanting their redesigned artificial heart in a human.
Norm Brown, director of the University of Utah's Technology Transfer Office, said he received word that the patent for the Utah-100 heart was approved more than a month ago. But Donald B. Olsen, director of the U.'s Artificial Heart Research Laboratory, said Thursday he hasn't received official patent papers yet.Dr. William A. Gay Jr., surgical director of the UTAH Cardiac Program, said in May 1990 that the Utah-100 artificial organ is ready to be implanted in a human as a bridge before a human heart transplant.
The Utah-100 heart is a redesign of the Jarvik 7-70 artificial heart.
Last January, the FDA withdrew approval of the Utah-developed Jarvik-7, which made medical history in 1982 when University of Utah surgeons inserted it in the chest of Seattle dentist Dr. Barney Clark and prolonged his life for 112 days.
The Jarvik heart was manufactured by Arizonia-based Symbion, Inc., but the FDA withdrew approval because of quality control problems in its manufacture.
