Pediatric Surgery

In the 1980’s Dr. Alberto Peña pioneered the PSARP (posterior sagittal anorectoplasty) procedure which requires the precise location of the striated muscle structures during the repair of anorectal malformations with the assistance of an electric stimulator. The initial “Peña” stimulator was in use for many years. However, that device no longer produced nor supported and, recently, has been starting to fail. Digitimer’s new DS7AP muscle locating stimulator is the perfect and safe replacement for those old stimulators. The DS7AP is FDA cleared and is in use in over 120 children’s hospitals in the USA and more throughout the world including Dr. Peña's Children’s Hospital of Colorado.
