Device for Biopsy of Tumors

Abstract

A device and method of use for securing and coring of tumors within the body during a biopsy of the tumor, specifically breast tumors. An adhesion probe for securing the tumor is described. The probe secures the tumor by piercing the tumor and providing a coolant to the distal tip to cool the tip. The cooled tip adheres to the tumor. A coring instrument adapted for cutting a core sample of the tumor is described. The instrument is provided with a cannula that can cut a core sample of the tumor. The instrument is adapted for use with the probe with the probe fitting within the cannula. The instrument can be used in conjunction with the probe to secure and core a sample of the tumor for biopsy.

1 . A biopsy device for securing and coring a mass within the breast of a human patient during a biopsy of said mass, said biopsy device comprising: 
 an adhesion probe comprising: 
 a rigid tube adapted for insertion into the body of the patient, said rigid tube having a proximal end, a distal end, a proximal segment having a first outer diameter, a distal segment having a second outer diameter, the first outer diameter being larger than the second outer diameter;  
 said distal segment adapted to be adhered to the mass within the breast;  
   a cannula, having a proximal end and a distal end, adapted for use with the adhesion probe, and said cannula comprising: 
 a tube having a lumen extending from the proximal end to the distal end, said lumen having an internal diameter approximately matching the first outer diameter of the proximal segment of the adhesion probe;  
 said cannula adapted for insertion into the body of the patient over the adhesion probe; and  
 said cannula being slidable over the adhesion probe.
