Claims Analysis

Total Claims: 13

Claim 1

Independent Claim 192 words

An apparatus for applying surgical clips comprising: a) a handle portion; b) a body portion extending distally from said handle portion; c) jaw members positioned adjacent the distal end of the body portion and movable between an open position for receiving a clip and a closed position for forming the clip; d) camming means operable from the handle portion and cooperative with the jaw members for camming the jaw members closed to form the clip; e) storage means disposed within said body portion proximate the jaw members for storing a plurality of clips in a position for individual advancement to the jaw members; f) clip advancement means for individually advancing clips from the storage means into the jaw members; and g) control means operatively associated with said handle portion for selecting between a first mode in which advancement of a clip from said storage means to said jaw members is effectuated by manually releasing said clip advancement means from a preadvancement position and a second mode in which said clip advancement means is automatically released from said pre-advancement position as said jaw members move from said closed position to said open position.

Claim 2

Independent Claim 192 words

Claim 3

Dependent Claim 22 words

An apparatus as recited in claim 1, wherein said clip advancement means comprises a clip pusher operatively disposed in said body portion.

Claim 4

Dependent Claim 50 words

An apparatus as recited in claim 2, wherein said control means includes means for releasably locking a pusher tube associated with said clip pusher in a locked position wherein said clip pusher is in a position proximal to a distal-most clip in said storage means corresponding to said pre-advancement position.

Claim 5

Dependent Claim 34 words
