主权项

1. An endoscopic instrument assembly, comprising:
an endoscope having a working channel formed therein and a distal port; a catheter extending through the working channel, wherein the catheter includes a ridge at a distal end of the catheter that defines a trigger attached to a needle assembly, the needle assembly comprising a distally-extending needle; and an elevator disposed adjacent the distal port, the elevator being configured to engage the ridge, wherein engagement between the elevator and the ridge causes the ridge and the needle assembly to move relative to the catheter, the elevator being configured to exert a force on the ridge to slide a distal end of the needle from a position within the catheter to a position distally extending from the catheter.
