Multi-clip device
First Claim
1. A multi-clip device for use in endoscopic medical procedures comprising:
- a) an introducing tube;
b) an operating wire disposed within the introducing tube, the operating wire being advanceable and retractable relative to the introducing tube; and
c) a plurality of detachable clips, each clip comprising an engagement portion, a plurality of arms, and a slidable collar disposed about the plurality of arms, said slidable collar being movable between a first position when said clip is in an open position and a second position when said clip is in a closed position, said slidable collar being configured to cause a distal end of the plurality of arms to be move towards each other when in the second position, the slidable collar comprising an expandable portion being movable between a compressed position when said clip is disposed within the introducing tube and an expanded position when said clip is at least partially disposed beyond a distal end of the introducing tube, said expandable portion being configured to be engaged by the distal end of the introducing tube when in the expanded position, wherein the plurality of detachable clips comprises at least a distal clip and a proximal clip disposed in the introducing tube and arranged in a serial fashion such that the distal clip is disposed distally of the proximal clip, further wherein the engagement portion of the distal clip is releasably engaged by one or more of the arms of the proximal clip, and the engagement portion of the proximal clip is operably connected to the operating wire.

Abstract
A multi-clip device for hemostasis includes an introducing tube (outer sheath) insertable into a body cavity. An operating wire is disposed within the introducing tube, and is advanceable and retractable within the introducing tube. A plurality of detachable clips are arranged in a serial fashion within the introducing tube. Each clip has an engagement portion at the proximal end thereof and a plurality of arms extending towards the distal end thereof. The distal end of the operating wire engages the engagement portion of the proximal most clip, and the arms of the proximal most clip engage the engagement portion of the adjacent distally located clip. An expandable collar is slidably disposed about the arms of the clip and is configured such that when the collar is moved distally over the arms it closes and holds them in a closed position. The expandable collar has an expanding portion that is engaged by the distal end of the introducing tube so that the introducing tube can be used to advance the collar distally relative to the clip.
