Woven surgical drain and method of making
First Claim
1. A woven surgical drain comprising:
- a first plurality of yarns and a second plurality of yarns, the yarns of said first plurality of yarns being substantially parallel to each other and extending in a first direction, the yarns of said second plurality of yarns being substantially parallel to each other and extending in a second direction substantially perpendicular to said first direction and woven with said first plurality of yarns to form an elongate woven fabric defining a tube-like channel having an external surface defining a longitudinal length and wherein said first plurality of yarns and said second plurality of yarns include conductive and nonconductive yarns and said conductive yarns make electrical contact with one another so as to form an electrically conductive matrix, and a non-stick coating applied to the external surface of said drain.

Abstract
The present invention relates to a surgical drain fabric and surgical drain device and surgical sponge for providing a channel of exit or discharge from a wound or wound cavity and, more specifically, a woven surgical drain fabric, woven surgical drains, and woven surgical sponges having finished longitudinal edges useful for drawing wound drainage out of a patient'"'"'s body. Preferably, the surgical drain fabric, surgical drains, and surgical sponges are woven with conductive yarns and nonconductive yarns so as to provide enhanced drainage characteristics. The fabric, drains, and sponges prepared in accordance with the invention minimize the danger of sluffing and linting and other disadvantages associated with previous surgical drain and sponge materials. A non-stick coating is applied to the external surface of the drain to reduce tissue adhesion to the drain.
