Sphincterotome device and methods and uses thereof

Abstract

A sphincterotome device can be used to achieve appropriate positioning within the biliary duct during cannulation. The sphincterotome device enables performance of a “double-wire” or multiple wire procedure without the need for removal and reintroduction of the sphincterotome device, thereby allowing for a shorter procedure.

1 . A sphincterotome device comprising:
 a shaft having a proximal end and a distal end;   a first lumen extending from the proximal end of the shaft to a first segment of the distal end of the shaft,   wherein a first exit port of the first lumen at the first segment is a first predetermined distance from a tip of the shaft;   a cutting wire disposed within the first lumen,   wherein a distal end of the cutting wire exits the first exit port and is coupled to the tip,   wherein movement of the cutting wire within the first lumen causes deflection of the tip;   a second lumen that extends from the proximal end of the shaft to a second exit port at the tip for accommodating a first guidewire; and   a third lumen that extends from the proximal end of the shaft to the first segment of the distal end of the shaft for accommodating a second guidewire,   wherein a third exit port of the third lumen is between the first exit port and the tip along the shaft.   
     
     
         2 . The sphincterotome device according to  claim 1 ,
 wherein a proximal end of the cutting wire is coupled to a slider, and   wherein movement of the slider along the shaft causes the movement of the cutting wire for deflection of the tip.   
     
     
         3 . The sphincterotome device according to  claim 1 ,
 wherein a proximal end of the cutting wire exits a first entry port at the proximal end of the shaft.   
     
     
         4 . The sphincterotome device according to  claim 1 ,
 wherein the first exit port and the third exit port are oriented at a same oblique angle with respect to a central axis of the shaft.   
     
     
         5 . The sphincterotome device according to  claim 4 ,
 wherein the first exit port is circumferentially offset from the third exit port.   
     
     
         6 . The sphincterotome device according to  claim 1 ,
 wherein the first exit port and the third exit port are oriented at oblique angles with respect to a central axis of the shaft.   
     
     
         7 . The sphincterotome device according to  claim 1 , further comprising:
 a handle coupled to the proximal end of the shaft,   wherein rotation of the handle causes rotation of the distal end of the shaft.   
     
     
         8 . The sphincterotome device according to  claim 1 , further comprising:
 a fourth lumen that extends from the proximal end of the shaft to the first segment of the distal end of the shaft.   
     
     
         9 . The sphincterotome device according to  claim 8 , further comprising:
 a fifth lumen that extends from the proximal end of the shaft to the tip.   
     
     
         10 . A sphincterotome device comprising:
 a shaft having a proximal end and a distal end;   a first lumen extending from the proximal end of the shaft to a first segment of the distal end of the shaft,   wherein a first exit port of the first lumen at the first segment is a first predetermined distance from a tip of the shaft;   a cutting wire disposed within the first lumen,   wherein movement of the cutting wire within the first lumen causes deflection of the tip;   a second lumen that extends from the proximal end of the shaft to a second exit port at the tip; and   a third lumen that extends from the proximal end of the shaft to the first segment of the distal end of the shaft,   wherein a third exit port of the third lumen is between the first exit port and the tip along the shaft,   wherein a distal end of the cutting wire exits the first exit port and is coupled to the shaft after the third exit port but before the tip.
