Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
121 words
A surgical instrument for applying fasteners to tissue comprising: an endoscopic portion having a proximal end portion, a distal end portion and a longitudinal axis; a pair of jaws extending generally longitudinally from the endoscopic distal end portion, each of the jaws having fastener carrying means for carrying surgical fasteners, wherein both the endoscopic portion and the jaws are adapted to be insertable into a cannula; and a plurality of surgical fasteners disposed within the fastener carrying means of each jaw, each surgical fastener having a pair of legs joined by a backspan, wherein the fastener backspans are oriented substantially perpendicular to the longitudinal axis of the endoscopic portion and are ejected towards said longitudinal axis when the instrument is fired.
Claim 2
Dependent Claim
121 words
A surgical instrument for applying fasteners to tissue comprising: an endoscopic portion having a proximal end portion, a distal end portion and a longitudinal axis; a pair of jaws extending generally longitudinally from the endoscopic distal end portion, each of the jaws having fastener carrying means for carrying surgical fasteners, wherein both the endoscopic portion and the jaws are adapted to be insertable into a cannula; and a plurality of surgical fasteners disposed within the fastener carrying means of each jaw, each surgical fastener having a pair of legs joined by a backspan, wherein the fastener backspans are oriented substantially perpendicular to the longitudinal axis of the endoscopic portion and are ejected towards said longitudinal axis when the instrument is fired.
Claim 3
Dependent Claim
17 words
The instrument of claim 1, wherein the fastener carrying means has a plurality of fastener receiving slots.
Claim 4
Dependent Claim
22 words
The instrument of claim 1, wherein the fastener carrying means is at least one cartridge having a plurality of fastener receiving slots.
Claim 5
Dependent Claim
40 words
The instrument of claim 1, wherein each jaw is movable between an open position and a closed position and wherein both jaws are in substantial parallel alignment with the longitudinal axis of the endoscopic portion when in the closed position.
Claim 6
Dependent Claim
23 words
The instrument of claim 4, wherein the fastener legs are oriented toward the longitudinal axis when the jaws are in the closed position.
Claim 7
Dependent Claim
15 words
The instrument of claim 4, further comprising means for ejecting the fasteners from each jaw.
Claim 8
Dependent Claim
24 words
The instrument of claim 4, further comprising at least one cam member disposed in each jaw for sequentially ejecting the fasteners from each jaw.
Claim 9
Dependent Claim
14 words
The instrument of claim 1, further comprising anvilless means for deforming the fastener legs.
Claim 10
Dependent Claim
21 words
The instrument of claim 1, further comprising jaw pivoting means for pivoting the pair of jaws between open and closed positions.
Claim 11
Dependent Claim
24 words
The instrument of claim 1, wherein at least one of the jaws is pivotable relative to the proximal end portion of the endoscopic portion.
Claim 12
Dependent Claim
44 words
The instrument of claim 1, further comprising a handle assembly disposed at the proximal endoscopic end portion, the handle assembly having a stationary handle and a movable handle, wherein movement of the movable handle causes the jaws to pivot between open and closed positions.
Claim 13
Dependent Claim
97 words
A surgical instrument comprising: an elongated portion having proximal and distal end portions and a longitudinal axis; a pair of jaws extending generally longitudinally from the distal end portion, at least one of the jaws being movable relative to the longitudinal axis of the elongated portion; and a plurality of fasteners disposed within each jaw, wherein each fastener has a pair of legs joined by a backspan, each fastener backspan being oriented substantially perpendicular to the longitudinal axis of the endoscopic portion and wherein each fastener is ejected towards said longitudinal axis when the instrument is fired.
Claim 14
Dependent Claim
97 words
A surgical instrument comprising: an elongated portion having proximal and distal end portions and a longitudinal axis; a pair of jaws extending generally longitudinally from the distal end portion, at least one of the jaws being movable relative to the longitudinal axis of the elongated portion; and a plurality of fasteners disposed within each jaw, wherein each fastener has a pair of legs joined by a backspan, each fastener backspan being oriented substantially perpendicular to the longitudinal axis of the endoscopic portion and wherein each fastener is ejected towards said longitudinal axis when the instrument is fired.
Claim 15
Dependent Claim
40 words
The instrument of claim 12, wherein each jaw is movable between an open position and a closed position and wherein both jaws are in substantial parallel alignment with the longitudinal axis of the endoscopic portion when in the closed position.
Claim 16
Dependent Claim
35 words
The instrument of claim 13, wherein each fastener has a pair of legs joined by a backspan and the fastener legs are oriented toward the longitudinal axis when the jaws are in the closed position.
Claim 17
Dependent Claim
14 words
The instrument of claim 12, further comprising anvilless means for deforming the fastener legs.
Claim 18
Dependent Claim
15 words
The instrument of claim 12, further comprising means for ejecting the fasteners from each jaw.
Claim 19
Dependent Claim
24 words
The instrument of claim 12, further comprising at least one cam member disposed in each jaw for sequentially ejecting the fasteners from each jaw.
