Method of applying thrombic powder in laparoscopic procedures
First Claim
1. A laparoscopic powder injector comprising a tube adapted to be inserted through a cannula for use in a scopic procedure, said tube having a first end and a second end;
- means to introduce and hold powdered agent in said tube;
means to force said powdered agent through said tube and out said first end wherein said means to introduce and hold powder agent in said tube comprises a chamber open into an interior portion of said second end of said tube, said tube having a tapered portion adjacent said chamber whereby powder can be added to said chamber when said first end is inserted into said cannula wherein said means to introduce and hold powder agent in said tube comprises a capsule containing said powder having first and second ends, wherein said tube includes a port adapted to open and receive said capsule, enclose and hold said capsule in place wherein said capsule comprises a rigid tube covered at both ends with frangible sheets, said sheets comprising a thrombic agent.

Abstract
An apparatus to force powdered agent, such as a thrombic agent, into the operative site of a laparoscopic procedure includes an elongated tube, a powder chamber and a mechanism to force the powder through the tube. Generally, this mechanism will be a source of pressurized air such as an air bulb, a syringe or a tank or cartridge of gas. In an alternate embodiment, the chamber can receive a tubular capsule full of the powder which is open at both ends so that air forced through the tube will force powder in the capsule through the tube and into the operative site.
