title: Assessment of a new device for injecting bovine collagen. The ADG needle.
abstract: BACKGROUND Bovine collagen has been injected into skin through conventional needles since its introduction in 1981. Variations in technique have resulted in a wide range of clinical results. The success of a collagen treatment depends on proper technique and placement, which may take years of experience to develop. Collagen Corporation has developed a new tool, the ADG needle, which allows more exact control over the depth of injection.
  
  
  OBJECTIVE
  To study the clinical benefits of this device in a field evaluation.
  
  
  METHODS
  Experienced collagen injectors were asked to evaluate the ADG needle and complete a survey on their experience.
  
  
  RESULTS
  A review of treatment of 63 patients by 19 physicians indicated enthusiasm for the new device. Respondees felt that the ADG needle enhanced their ability to place collagen in the dermis and increased the speed of collagen injection.
  
  
  CONCLUSIONS
  The ADG needle is a new tool that enhances depth control and speed when injecting bovine collagen.
