Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
192 words
A cartridge for housing a plurality of surgical clips that have opposed, hinged leg portions that define side surfaces and which are movable between an open position and a closed position, at least one of the leg portions having a boss portion extending outwardly therefrom, said cartridge comprising: a base member having at least one cavity formed therein for receipt of a surgical clip therein; said cavity having a floor portion, a pair of opposed, upstanding parallel side walls that are adjusted to be oriented adjacent the side surfaces of a surgical clip and a pair of opposed, upstanding end walls that are adapted to be oriented adjacent at least one boss portion of the clip; spacer portions extending inwardly into said cavity at the intersection of said side walls and said end walls so as to define a generally key-shaped cavity for locating a surgical clip in a spaced relationship from said end walls; and said floor portion and said spacer portions being configured so as to conform to and support the leg portions of a surgical clip as the surgical clip moves between an open position and a closed position.
Claim 2
Dependent Claim
192 words
A cartridge for housing a plurality of surgical clips that have opposed, hinged leg portions that define side surfaces and which are movable between an open position and a closed position, at least one of the leg portions having a boss portion extending outwardly therefrom, said cartridge comprising: a base member having at least one cavity formed therein for receipt of a surgical clip therein; said cavity having a floor portion, a pair of opposed, upstanding parallel side walls that are adjusted to be oriented adjacent the side surfaces of a surgical clip and a pair of opposed, upstanding end walls that are adapted to be oriented adjacent at least one boss portion of the clip; spacer portions extending inwardly into said cavity at the intersection of said side walls and said end walls so as to define a generally key-shaped cavity for locating a surgical clip in a spaced relationship from said end walls; and said floor portion and said spacer portions being configured so as to conform to and support the leg portions of a surgical clip as the surgical clip moves between an open position and a closed position.
Claim 3
Dependent Claim
83 words
A cartridge according to claim 1 further including a retainer member positioned above said base member, said retainer member having an opening that is generally located in alignment with a cavity in said base member, said opening being defined by opposed upstanding parallel side walls and opposed upstanding end walls, said retainer member having retaining lip portions that extend inwardly into said opening for contacting a boss portion of a surgical clip for retaining the surgical clip in contact with said base member.
Claim 4
Dependent Claim
45 words
A cartridge according to claim 2 wherein said retaining lip portions extend inwardly from the intersection of said side walls and said end walls of said opening so as to define a key-shaped cavity in general alignment with said key-shaped cavity in said base member.
Claim 5
Dependent Claim
64 words
A cartridge according to claim 3 wherein said end walls of said opening in said retaining member and said end walls of said cavity in said base member are spaced apart so as to permit a pair of spaced apart jaw portions of an applier to extend therebetween and move past and grasp the boss portion of a surgical clip positioned in said cavity.
Claim 6
Dependent Claim
59 words
A cartridge according to claim 4 wherein said side walls of said opening in said retaining member are spaced apart so as to permit side shield flanges extending from the jaw portions of the applier to extend into said opening and cavity and move adjacent the sides of the surgical clip as the jaw portions grasp the surgical clip.
Claim 7
Dependent Claim
53 words
A cartridge according to claim 5 wherein said floor portion and said spacer portions define ramps that permit the clip to remain in contact therewith as the boss portion of a clip is contacted by a distal end of the jaw portions of an applier and caused to deflect towards its closed position.
