International Classification:

A61B 17/04

US Classification:

2271791, 2271751

Abstract:

An assembly for joining tissue is provided and includes an anvil assembly and a body portion juxtaposed with respect to one another along a shaft and arranged so as to be approximated with respect to one another; and an applicator supported on the anvil assembly and configured for retaining a wound treatment material therein and for dispensing the wound treatment material therefrom. A method for joining tissue is provided and includes the steps of dispensing the wound treatment material from the applicator so as to distribute wound treatment material onto at least one of a first tissue section and a second tissue section; and approximating the anvil assembly and the body portion to one another so that the first tissue section and the second tissue section are in contact with one another with the dispensed wound treatment material interposed there between.

US Classification:

606145, 606139, 606144

Abstract:

An endoscopic stitching device includes a tool assembly having a pair of juxtaposed jaws pivotally associated with one another, each jaw defining a needle receiving recess formed in a tissue contacting surface thereof; a drive assembly including a pair of concentric, individually rotatably and translatably supported barrels, each barrel defining a central lumen therethrough; and a pair of axially translatable needle engaging blades slidably supported, one each, in a respective jaw. The stitching device further includes a center rod slidably and rotatably disposed through the lumen of the barrels, a distal end of the center rod being operatively engaged with the pair of jaws.
