Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
204 words
In a surgical fastening system for joining tissue, said system comprising a plurality of parallel rows of staples and a plurality of parallel rows of receivers, each of said staples comprising a pair of legs, said legs being joined at one end thereof by a linking member, the opposite end of each leg being adapted to penetrate tissue so the linking member lies adjacent the tissue penetrated by said legs, each receiver having a body portion and a plurality of openings disposed in said body portion, said openings being located so as to engage the legs of the staple after said legs have penetrated the tissue so that the receiver lies on the opposite side of the tissue to be joined, means on said legs and on said receivers for interlocking the staple and the receiver together; the improvement comprising each receiver being connected to at least two receivers in an adjacent row with each connection comprising a plurality of parallel linkages between receivers, said linkages being flexible and sufficiently strong to maintain the receivers connected during both the application of the fastening system when joining the tissue and the use of the fastening system to hold the tissue until such tissue has healed.
Claim 2
Dependent Claim
204 words
In a surgical fastening system for joining tissue, said system comprising a plurality of parallel rows of staples and a plurality of parallel rows of receivers, each of said staples comprising a pair of legs, said legs being joined at one end thereof by a linking member, the opposite end of each leg being adapted to penetrate tissue so the linking member lies adjacent the tissue penetrated by said legs, each receiver having a body portion and a plurality of openings disposed in said body portion, said openings being located so as to engage the legs of the staple after said legs have penetrated the tissue so that the receiver lies on the opposite side of the tissue to be joined, means on said legs and on said receivers for interlocking the staple and the receiver together; the improvement comprising each receiver being connected to at least two receivers in an adjacent row with each connection comprising a plurality of parallel linkages between receivers, said linkages being flexible and sufficiently strong to maintain the receivers connected during both the application of the fastening system when joining the tissue and the use of the fastening system to hold the tissue until such tissue has healed.
Claim 3
Dependent Claim
19 words
A surgical fastening system according to claim 1 wherein the openings in the receiver each have an oval shape.
Claim 4
Dependent Claim
17 words
A surgical fastening system according to claim 1 wherein each connection between receivers comprises three parallel linkages.
Claim 5
Independent Claim
72 words
A system for holding surgical staples comprising receivers having a body portion and plurality of openings in said portion, said receivers held in parallel rows by means of a plurality of linkages attached to a row maintaining cassette on the outside of said parallel rows, said row maintaining cassette comprising a pair of parallel rails connected by a pair of parallel ramps, said ramps configured for emplacement beneath a receiver maintaining mold.
Claim 6
Independent Claim
72 words
A system for holding surgical staples comprising receivers having a body portion and plurality of openings in said portion, said receivers held in parallel rows by means of a plurality of linkages attached to a row maintaining cassette on the outside of said parallel rows, said row maintaining cassette comprising a pair of parallel rails connected by a pair of parallel ramps, said ramps configured for emplacement beneath a receiver maintaining mold.
Claim 7
Dependent Claim
42 words
The system of claim 4 wherein said ramps are capable of receiving a breaking force, said force causing motion of said row maintaining cassette with respect to said receivers, said force causing said plurality of linkages to break away from said receivers.
Claim 8
Dependent Claim
22 words
The system of claim 5 wherein each receiver is connected to said row maintaining cassette by at least one of said linkages.
Claim 9
Dependent Claim
16 words
The system of claim 6 wherein said linkages have a cross sectional diameter of about 0.005".
Claim 10
Dependent Claim
16 words
The system of claim 4 wherein said openings in the receiver each have an oval shape.
Claim 11
Independent Claim
103 words
A system for holding surgical staples comprising receivers having a body portion and a plurality of openings in said body portion, said receivers held in parallel rows by means of a plurality of linkages attached to a ribbon cassette outside said parallel rows, said ribbon cassette comprising a flat plate adapted for emplacement on a platform, said ribbon cassette causing said receivers to have a clearance from the base of said platform such that when surgical staples are driven into said receivers, forces imparted on said receivers from said surgical staples cause said linkages to break, separating said ribbon cassette from said receivers.
Claim 12
Independent Claim
103 words
A system for holding surgical staples comprising receivers having a body portion and a plurality of openings in said body portion, said receivers held in parallel rows by means of a plurality of linkages attached to a ribbon cassette outside said parallel rows, said ribbon cassette comprising a flat plate adapted for emplacement on a platform, said ribbon cassette causing said receivers to have a clearance from the base of said platform such that when surgical staples are driven into said receivers, forces imparted on said receivers from said surgical staples cause said linkages to break, separating said ribbon cassette from said receivers.
Claim 13
Dependent Claim
22 words
The system of claim 9 wherein each receiver is connected to said ribbon cassette by means of at least two said linkages.
Claim 14
Dependent Claim
16 words
The system of claim 10 wherein said linkages have a cross sectional diameter of about 0.005".
Claim 15
Dependent Claim
16 words
The system of claim 9 wherein said openings in said receiver each have an oval shape.
Claim 16
Dependent Claim
178 words
In a surgical fastening system for joining tissue, said system comprising a plurality of parallel rows of staples and a plurality of parallel rows of receivers, each of said staples comprising a pair of legs, said legs being joined at one end thereof by a linking member, the opposite end of each leg being adapted to penetrate tissue so the linking member lies adjacent the tissue penetrated by said legs, each receiver having a body portion and a plurality of openings disposed in said body portion, said openings being located so as to engage the legs of the staple after said legs have penetrated the tissue so that the receiver lies o the opposite side of the tissue to be joined, means on said legs and on said receivers for interlocking the staple and the receiver together; the improvement comprising each receiver being connected to a least two receivers in an adjacent row by means of a web extending between said rows, wherein each of said receivers are attached to the web at and along longitudinally opposing sides.
Claim 17
Dependent Claim
178 words
In a surgical fastening system for joining tissue, said system comprising a plurality of parallel rows of staples and a plurality of parallel rows of receivers, each of said staples comprising a pair of legs, said legs being joined at one end thereof by a linking member, the opposite end of each leg being adapted to penetrate tissue so the linking member lies adjacent the tissue penetrated by said legs, each receiver having a body portion and a plurality of openings disposed in said body portion, said openings being located so as to engage the legs of the staple after said legs have penetrated the tissue so that the receiver lies o the opposite side of the tissue to be joined, means on said legs and on said receivers for interlocking the staple and the receiver together; the improvement comprising each receiver being connected to a least two receivers in an adjacent row by means of a web extending between said rows, wherein each of said receivers are attached to the web at and along longitudinally opposing sides.
Claim 18
Dependent Claim
