Seton Healthcare Family – Patent Pending

As part of our commitment to innovation, Seton has helped develop some of our associates’ ideas into a reality that can benefit not only our own patients, but the entire healthcare field as a whole. One of these medical devices comes from Dr. James Allred.

The invention is a simple-to-use, cost-effective shave biopsy device with depth gauge that can be used to sample tissue safely, effectively and accurately. The depth gauge provides the user real-time slicing depth to facilitate excising a sufficient portion of a skin lesion while minimizing excess tissue removal and risk for scarring.


Shave biopsy is a common technique utilized by clinicians to obtain a tissue sample for determining if a skin lesion is benign or potentially harmful to a patient. During a shave biopsy, a portion of a skin lesion is typically shaved off. As such, the slicing depth can be critical. If the biopsied lesion is too deep, the risk for bleeding, infections, damage to underlying tissue structures, scarring, and slow healing, is increased. On the other hand, if a biopsy is too shallow, adequate staging of the biopsied lesion and/or future treatment can be unnecessarily complicated.


  • Intuitive and simple to use
  • Low-cost
  • Real-time, accurate depth measurement
  • Minimizes excess tissue removal
