A Surgical Needle Probe for Electrical Impedance Measurements

An electrical impedance probe constructed within a surgical needle. The probe consists of a two-part trocar needle designed to acquire impedance measurements at its point. Since the impedance of cells varies by cell type, the new probe may be used to confirm needle position in a desired anatomical target or to identify the nature of cells surrounding the tip of the needle Description (Set) Proposed Use (Set) In urology this sensor is used for confirming the needle insertion into the urinary tract, for localizing renal cell carcinoma, and prostate cancer.
