1. An endoscopic device for delivering a quantity of material comprising:
- a handle portion;
an elongated endoscopic portion having a proximal end extending from said handle portion and a distal end, said endoscopic portion having a passageway extending therethrough configured to emit material only from said distal end;
material containment means disposed within said handle portion for storing at least a particulate material to be delivered and a pressurized propellant for propelling said particulate material from said material containment means, said material containment means including seal means communicating with a proximal end of said passageway for permitting the propulsion of said particulate material therefrom; and
actuation means operably connected to said material containment means for causing said seal means to open and permit a quantity of said particulate material to be propelled from said material containment means, through said passageway, out of said distal end of said endoscopic portion.

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.

10. A device for endoscopic delivery of a material comprising:
-
a handle portion; an endoscopic delivery portion extending distally from said handle portion and having a passageway extending therethrough; material containment means disposed within said handle portion and communicating with said passageway for storing at least a material to be delivered and a pressurized propellant for propelling said material through said endoscopic delivery portion, said material containment means including seal means for permitting the propulsion of said material therefrom; and pivotal actuating means operatively connected to said material containment means for causing said seal means to open and permit a quantity of said material to be delivered from said material containment means. - View Dependent Claims (11, 12, 13, 14, 15)

16. An endoscopic device for delivering a quantity of material comprising:
-
a handle portion; an endoscopic portion having opposed proximal and distal ends, said proximal end connected to said handle portion and having a passageway extending therethrough from said proximal end to said distal end thereof; material containment means disposed within said handle portion for storing at least a material to be delivered under pressure, said material containment means including seal means in communication with a proximal end of said passageway for permitting the propulsion of said material therefrom; a trigger movably connected to said handle portion; and a plunger operatively connected to said trigger for urging said plunger distally against said material containment means to cause said seal means to open and permit at least a portion of the material contained therein to be expelled therefrom so as to be delivered out of said distal end of said endoscopic portion.

17. An endoscopic device for delivering a metered quantity of material comprising:
-
a handle portion having a longitudinally extending barrel portion and having opposed proximal and distal ends; a port formed in said distal end of said barrel portion; a trigger movably connected to said handle portion; an elongated endoscopic member having a proximal end portion engageable in said port and having a passageway extending from said proximal end portion to a distal end thereof; a removable cartridge disposed in said handle portion and communicating with said passageway, said cartridge containing a pressurized propellent and material for delivery through said passageway in said endoscopic member, said cartridge including a frangible seal member for permitting the pressurized propulsion of said material therefrom; and plunger means operatively connected to said trigger for urging said cartridge in a distal direction causing said frangible seal member to be pierced and permit a metered quantity of said material to be expelled therefrom and delivered out of said distal end of said endoscopic member. - View Dependent Claims (18)
