Laparoscopic hemostat delivery system and method for using said system
First Claim
1. A method for directly applying a plug of hemostatic material against an internal vascular tissue site of a patient during a laparoscopic procedure, comprising the steps of,charging a hollow sheath having a distal end and a proximal end with a plug of hemostatic material,passing the distal end of said sheath through a channel of a laparoscopic cannula, and guiding the distal end of said sheath to a position facing the vascular tissue site,passing a plunger through a lumen of said hollow sheath, thereby advancing the plug of hemostatic material in said lumen, such that a portion of the plug of hemostatic material exits the distal end of the hollow sheath, andmechanically applying with pressure the distally extending portion of the plug of hemostatic material against the vascular tissue site to effect rapid hemostasis.

Abstract
A delivery system and method for inserting hemostatic material through a channel of a laparoscopic cannula, and for directly applying the material to an internal tissue site, includes a hollow sheath having a cross-section and configuration that permits sliding passage thereof through the channel of the laparoscopic cannula. The sheath is charged with hemostatic material, and the hemostatic material is advanced through the lumen of the sheath and mechanically applied at the tissue site by an applicator. The hemostatic material may be in the form of compressed loose fibers, a sponge, a powder, a paste, a sheet, or a combination thereof, and may be composed of resorbable collagen.
