Multiple biopsy device

Abstract

A biopsy device includes a first jaw and a second jaw pivotally connected to the first jaw through a pivot. The second jaw has a lever arm extending rearward from the pivot when the second jaw is closed. A wire having an end is connected to the lever arm of the second jaw. A suction tube is disposed between the first and second jaw.

1 . A biopsy assembly comprising:
 a biopsy forceps device having at least one movable jaw, wherein the movable jaw is pivotally connected to a stationary jaw by a pivot;   a connector;   an actuation handle;   a catheter extending from the biopsy forceps device and through the connector;   a wire extending from the actuation handle, through the connector and into the catheter, to move the movable jaw; and   a suction device operatively connected to the catheter.   
     
     
         2 . The biopsy assembly of  claim 1 , further comprising a collection chamber operatively connected to the catheter. 
     
     
         3 . The biopsy assembly of  claim 2 , wherein the collection chamber is configured to be connected to the actuation handle. 
     
     
         4 . The biopsy assembly of  claim 1 , further comprising suction tubing disposed between the movable jaw and the stationary jaw, wherein an open end of the suction tubing is positioned forward of the pivot. 
     
     
         5 . The biopsy assembly of  claim 1 , wherein the connector is a substantially y-shaped connector having a major chamber and a minor chamber. 
     
     
         6 . The biopsy assembly of  claim 5 , wherein the catheter passes through the major chamber of the connector. 
     
     
         7 . The biopsy assembly of  claim 5 , wherein a cannula is disposed between the minor chamber of the connector and the actuation handle. 
     
     
         8 . The biopsy assembly of  claim 7 , wherein the wire is disposed within the cannula and passes through the minor chamber of the connector. 
     
     
         9 . The biopsy assembly of  claim 7 , wherein the cannula comprises a spring. 
     
     
         10 . The biopsy assembly of  claim 1 , wherein the catheter has at least one lumen, and the wire is at least partially disposed within the at least one lumen. 
     
     
         11 . The biopsy assembly of  claim 1 , wherein the at least one of the jaws is operably configured to deliver radio frequency energy to tissue. 
     
     
         12 . A biopsy device configured to be used with an endoscope, the biopsy device comprising:
 a biopsy forceps device having a first jaw and a second jaw;   a pivot connecting the first jaw to the second jaw;   a catheter extending from the biopsy forceps device; and   a suction tube disposed between the first jaw and the second jaw, the suction tube having an end positioned forward and at least partially between the pivot.   
     
     
         13 . The biopsy device of  claim 12 , wherein the first jaw includes a lever arm rearward of the pivot when the first jaw is closed. 
     
     
         14 . The biopsy device of  claim 13 , further comprising a wire having a first end connected to the lever arm of the first jaw and a second end connected to an actuation mechanism. 
     
     
         15 . The biopsy device of  claim 14 , wherein the wire of the biopsy device is operably configured to deliver RF energy to at least one jaw. 
     
     
         16 . The biopsy device of  claim 12 , wherein at least one of the first jaw and second jaw is fenestrated. 
     
     
         17 . A biopsy device comprising:
 a first jaw;   a second jaw pivotally connected to the first jaw through a pivot, the second jaw having a lever arm extending rearward from the pivot when the second jaw is closed;   a wire having an end connected to the lever arm of the second jaw; and   a suction tube disposed between the first and second jaw.   
     
     
         18 . The biopsy device of  claim 17 , further comprising a catheter extending from the first jaw with the suction tube and wire disposed within. 
     
     
         19 . The biopsy device of  claim 18 , wherein the first jaw has at least one tang extending from a rear end, and a distal portion of the catheter includes at least one aperture configured to receive the at least one tang. 
     
     
         20 . The biopsy device of  claim 18 , further comprising a tube having a plurality of lumens including at least a first lumen that receives the catheter and a second lumen in communication with a fluid source.
