  • Patent number: 7717860
    Abstract: An elliptical biopsy guide comprises a platform and a pair of wings extending from the platform. Each of the wings terminates in a respective curved member. The platform defines a plane, and comprises beveled aperture edges defining an aperture. Each of the aperture edges has a generally elliptical curvature. Each of the wings is angled relative to the plane defined by the platform. A user may exert outward forces with first and second fingers against the insides of respective curved members to hold the elliptical biopsy guide. The elliptical biopsy guide may be positioned over a biopsy site, and a downward force may be applied with the elliptical biopsy guide to provide skin tension or hemostasis. The aperture may be used as a template for excising tissue at the biopsy site.

  • Patent number: 5570700
    Abstract: An elliptical skin biopsy punch includes a blade which creates an elliptical incision in the skin of a patient, in which the blade's profile is circular, thereby allowing the biopsy punch to be rocked back and forth during the surgical procedure. Integral depth guards are provided which prevent the blade from penetrating too deeply into the skin membrane, and which help to inform the physician when the incision has been completed. An aperture or window is provided so the physician can directly view the skin lesion while positioning the biopsy punch before the start of the incision. The upper portion of the biopsy punch has alignment marks to help in correctly positioning the biopsy punch around the skin lesion. Several different sizes of elliptical skin biopsy punch can be made so that the proper incision will be used for any particular skin lesion's size. Several different handle shapes are available for various sized lesions and various types of physician's hands.
