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.
