Abstract: A bi-directional cannula for perfusing blood in two directions. The cannula has a distal opening in fluid communication with a cannula first lumen. The cannula has a secondary opening proximal of the distal opening, and may include a movable tubular extension selectively extendable from the cannula via the secondary opening. The tubular extension may be in fluid connection with the cannula first lumen and/or a cannula second lumen. The tubular extension may have distal and/or side openings, with the openings providing antegrade fluid perfusion. The cannula second lumen may be separate from the first lumen, so that perfusion can be selectively provided to just the cannula distal opening, just the secondary opening/tubular extension, or simultaneously to both the distal opening and secondary opening/tubular extension.

Abstract: A device is described that has an instrument portion secured to a sleeve/cuff portion, where the sleeve/cuff portion is configured to receive a portion of user's finger therein and to radially compress onto the user's finger to hold the instrument portion thereon. The present invention is particularly well suited for use in minimally invasive surgical procedures. The present invention also teaches a method of forming a knot in suture material as well as other techniques for treating patients.

Abstract: The disclosed invention is an apparatus for mooring a watercraft to a docking post or a stump, and a method of securing the watercraft to a stump. The apparatus is comprised of a hollow elongated pole of cylindrical shape with a handle in the central part and a rope that has a stiffened portion housed in the hollow elongated pole of cylindrical shape. The method for securing a watercraft is to provide a hollow elongated docking stick that has a handle and a rope housed in it with a stiffened portion. The stiffened loop of the rope is attached to one end of a docking stick, and a flexible line portion is attached to the other end of the rope, attaching the flexible line portion of the rope to the watercraft and attaching the stiffened loop of the rope to the docking member as watercraft is pulled alongside the stump.
