First Claim
1. A system for detecting tissue in a patient comprising:
- a surgical instrument configured for selective insertion into a patient, the surgical instrument further comprising an outer cannula having a tissue sampling aperture positioned adjacent a distal end of the outer cannula;
an inner cutting cannula positioned within the outer cannula, the inner cutting cannula including a cutting edge selectively moveable across the tissue sampling aperture to sever tissue; and
a sensor configured to detect at least one property of the tissue of said patient, the sensor fixedly attached to an inner surface of the outer cannula so as to contact tissue prolapsed through the sampling aperture, wherein the inner surface of the outer cannula to which the sensor is attached is oriented axially relative to a longitudinal axis of the outer cannula, and is positioned between the tissue sampling aperture and the distal end of the outer cannula.

Abstract
A system for detecting abnormal tissue in a patient including an introducer cannula having a proximal opening and a distal opening. The system further includes a surgical instrument configured for selective insertion through the cannula. The surgical instrument further includes a tissue cutting opening positioned relative to the distal end of the introducer cannula when fully inserted through the introducer cannula. The system also includes a sensor configured to detect at least one property of the tissue of the patient. The sensor is located at a fixed distance relative to the distal end of the introducer cannula when the surgical instrument is inserted into the introducer cannula.

36. A system for detecting a characteristic of tissue in a patient comprising:
-
an outer cannula having a tissue sampling aperture positioned adjacent a distal end of the outer cannula; an inner cutting cannula positioned within the outer cannula, the inner cutting cannula including a cutting edge selectively moveable across the tissue sampling aperture to sever tissue, and a lumen at least partially defining a fluid path for transporting the severed tissue away from the sampling aperture; and a sensor configured to detect abnormal tissue of the patient, the sensor positioned within the fluid path and the lumen. - View Dependent Claims (37, 38, 39, 40, 41, 42)
