Abstract
Abstract The present device discloses a grasping forceps with side channel. A grasping forceps channel connects a clamp to a handle. The clamp is shut to close off the gall bladder to prevent gall stones from traveling from the gall bladder into the cystic duct and into the bile duct. The side channel is provided that is substantially parallel to the grasping forceps channel. The side channel directs a catheter into the ampulla on the side of the clamp proximate to the bile duct. This catheter has a needle for application of a dye to the ampulla.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
89 words
A method of injecting dye into the infundibulum of the gallbladder for cholangiography in conjunction with surgical removal of a gallbladder comprising the steps of: (a) clamping said infundibulum of said gallbladder with a grasping means attached to means to direct a dye application means; (b) directing said dye application means through said means to direct a dye application means until said dye application means penetrates said infundibulum on the side of said grasping means distally located from said fundus; and (c) applying dye through said dye application means.
Claim 2
Independent Claim
89 words
A method of injecting dye into the infundibulum of the gallbladder for cholangiography in conjunction with surgical removal of a gallbladder comprising the steps of: (a) clamping said infundibulum of said gallbladder with a grasping means attached to means to direct a dye application means; (b) directing said dye application means through said means to direct a dye application means until said dye application means penetrates said infundibulum on the side of said grasping means distally located from said fundus; and (c) applying dye through said dye application means.
Claim 3
Dependent Claim
23 words
