  • Publication number: 20200330705
    Abstract: The present invention is directed to a spray applicator for spraying a tissue treatment medicant onto a tissue that has a container containing the medicant and is positioned at a proximal end of the spray applicator; a spray tip positioned at a distal end of the spray applicator; a cannula connecting the container with the spray tip; an actuatable dispensing mechanism at a proximal end of the applicator to express the medicant from the container through the cannula and through the spray tip toward the tissue; an optional pressurized gas source discharging a gas through the cannula in the vicinity of the spray tip or inside the spray tip; and a distance indicator that provides indicia of the distance between the spray tip and the tissue but does not prevent positioning the spray tip closer to the tissue than a defined distance for the distance indicator.

  • Publication number: 20200129258
    Abstract: A tissue expander having an integrated drain includes an outer shell having an opening and one or more drainage holes. An injection port is disposed in the opening of the shell and forms a fluid-tight seal with the shell. The injection port includes a needle guard having a needle guard base with a top surface, and a barrier membrane that overlies the top surface of the needle guard base. The barrier membrane defines an inflation chamber located between the top surface of the needle guard base and a bottom surface of the barrier membrane, and a drainage chamber overlying a top surface of the barrier membrane. The tissue expander includes one or more inflation ports that are in fluid communication with the inflation chamber for inflating and deflating the outer shell with a first fluid. A drainage conduit is in fluid communication with and extends between the drainage chamber and the one or more drainage holes for draining a second fluid from outside the shell.
