Multiple biopsy sampling coring device
First Claim
1. A device for collecting a sample of tissue from a tissue surface, comprising:
- a device body having a central axis and defining a forward facing tissue receiving opening coaxial with said central axis through which tissue may pass when said opening is near said tissue surface,a severing element forming a severing element tissue opening coaxial with said central axis, said severing element being actuable across said tissue receiving opening when tissue from said surface extends through said tissue receiving opening and said severing element tissue opening for severing said tissue from said surface, anda storage space proximal of and adjacent said tissue receiving opening for storage of multiple tissue samples by repeatedly passing tissue through said tissue receiving opening and actuating said severing element.

Abstract
A device and method for collecting from a tissue surface, a sample of tissue, including tissue specimens, polyps, or the like. A device body defines a forward-facing tissue receiving opening of substantially predetermined width through which tissue may pass when the opening is near the tissue surface. A severing element is actuatable across the width of the tissue receiving opening when tissue from the surface extends through the opening for severing the tissue from the surface. A storage space proximal of and adjacent the opening is provided for storage of multiple, successively taken samples by repeatedly passing tissue through the opening and actuating the severing element.
