Abstract
Abstract A device for delivering a quantity of material endoscopically to an intended site of application within a body through an incision or entrance wound includes a handle portion with movable trigger means, and an endoscopic portion. A reservoir or cartridge containing material for delivery may be disposed in the handle or endoscopic portion of the delivery device. In operation, the trigger means may be operated in such a manner so as to cause a discharge of a metered quantity of material from the proximal end of the endoscopic tube.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
161 words
An endoscopic device for device for delivering a metered quantity of material to a surgical site comprizing: a handle including a longitudinally extending barrel section having a reception port formed in a distal end thereof: an elongated endoscopic portion configured to be engaged in said reception port and having a passageway extending therethrough; a removable cartridge disposed in said barrel section of said handle portion and containing material for delivery through said passageway, said cartridge having a piercable seal at a distal end thereof; a canister of compressed gas disposed in said handle portion; actuation means for selectively discharging compressed gas from said canister; conduit means disposed in said handle portion and extending from said compressed gas source to said cartridge for conducting compressed gas from said canister to said cartridge; and means associated with a proximal end portion of said endoscopic portion for piercing said seal when said endoscopic portion is engaged in said reception port of said barrel section.
Claim 2
Dependent Claim
161 words
An endoscopic device for device for delivering a metered quantity of material to a surgical site comprizing: a handle including a longitudinally extending barrel section having a reception port formed in a distal end thereof: an elongated endoscopic portion configured to be engaged in said reception port and having a passageway extending therethrough; a removable cartridge disposed in said barrel section of said handle portion and containing material for delivery through said passageway, said cartridge having a piercable seal at a distal end thereof; a canister of compressed gas disposed in said handle portion; actuation means for selectively discharging compressed gas from said canister; conduit means disposed in said handle portion and extending from said compressed gas source to said cartridge for conducting compressed gas from said canister to said cartridge; and means associated with a proximal end portion of said endoscopic portion for piercing said seal when said endoscopic portion is engaged in said reception port of said barrel section.
Claim 3
Independent Claim
169 words
A device for delivering a quantity of material to a surgical site during an endoscopic procedure comprising: a handle portion including an elongated barrel section having a reception port formed in a distal end thereof; an elongated endoscopic portion having seal piercing means provided at a proximal end portion thereof engageable in said reception port and having a passageway extending therethrough; material containment means disposed within said barrel section of said handle portion for storing a quantity of material for delivery through said passageway, said material containment means having a piercable seal associated with a distal end thereof; propellant containment means disposed within said handle portion and operatively associated with said material containment means for storing a propellant for propelling a quantity of material from said material containment means; and actuation means operatively associated with said propellant containment means for selectively discharging propellant therefrom, whereby said seal is pierced by said seal piercing means when said proximal end portion of said endoscopic portion is engaged in said reception port.
Claim 4
Independent Claim
169 words
A device for delivering a quantity of material to a surgical site during an endoscopic procedure comprising: a handle portion including an elongated barrel section having a reception port formed in a distal end thereof; an elongated endoscopic portion having seal piercing means provided at a proximal end portion thereof engageable in said reception port and having a passageway extending therethrough; material containment means disposed within said barrel section of said handle portion for storing a quantity of material for delivery through said passageway, said material containment means having a piercable seal associated with a distal end thereof; propellant containment means disposed within said handle portion and operatively associated with said material containment means for storing a propellant for propelling a quantity of material from said material containment means; and actuation means operatively associated with said propellant containment means for selectively discharging propellant therefrom, whereby said seal is pierced by said seal piercing means when said proximal end portion of said endoscopic portion is engaged in said reception port.
Claim 5
Dependent Claim
26 words
A device as recited in claim 2, further comprising a conduit extending between said propellant containment means and said material containment means for facilitating communication therebetween.
Claim 6
Dependent Claim
20 words
A device as recited in claim 2, wherein said material containment means is configured as a removable and replaceable unit.
Claim 7
Dependent Claim
20 words
A device as recited in claim 2, wherein said propellant containment means is configured as a removable and replaceable unit.
Claim 8
Dependent Claim
41 words
A device as recited in claim 2, wherein propellant discharged from said propellant containment means imparts a force upon a proximal end of said material containment means to increase pressure therein and cause a quantity of material to be expelled therefrom.
Claim 9
Dependent Claim
26 words
A device as recited in claim 2, wherein access panel is associated with said barrel section of said handle portion for accessing said material containment means.
Claim 10
Independent Claim
168 words
A device for delivering a quantity of material to a surgical site during an endoscopic procedure comprising: a handle portion including an elongated barrel section having a reception port formed in a distal end thereof; an elongated endoscopic portion having a tapered proximal end portion engagable in said reception port and having a passageway extending therethrough; a material containment vessel disposed within said barrel section of said handle portion for storing a quantity of material for delivery through said passageway, said material containment vessel having a piercable seal associated with a distal end thereof; a propellant containment vessel disposed within said handle portion and operatively associated with said material containment vessel for storing a propellant for propelling a quantity of material from said material containment vessel; and an actuation mechanism operatively associated with said propellant containment vessel for selectively discharging propellant therefrom, whereby said seal is pierced by said tapered proximal end portion when said proximal end portion of said endoscopic portion is engaged in said reception port.
Claim 11
Independent Claim
168 words
