Device for performing biopsies on a vesicular object

Abstract

A device for removing material from a vesicular object, said device being a pipette having a sealed tip at its distal end and an aperture whereby the distal tip of the device is inserted into the target object, the aperture aligned with the material to be removed from the object, vacuum applied to the inside of the device, such vacuum drawing the material into the aperture, and the device being removed from the object in such a manner as to cut or otherwise separate the material in the pipette from the object, the material remaining in the pipette, while leaving the object undamaged.

I claim: 
     
         1 . A device for removing material from a vesicular object (object) said device being a pipette and having:
 a, a sealed tip at its distal end ( 2 ), the distal tip being sharp enough to puncture the object;   b, an aperture ( 1 ), both the specific location and size of the aperture being appropriate for the object and the material to be removed; and   c, the aperture having edges sharp enough to cut or otherwise separate the material in the pipette from the object;   
       whereby the distal tip of the device is inserted into the object, the aperture aligned with the material to be removed from the object, vacuum applied to the inside of the device, such vacuum drawing the material into the aperture, and the device being removed from the object in such a manner as to cut or otherwise separate the material in the pipette from the object, this material remaining in the pipette, while leaving the object undamaged.
