Definitions

  • the present invention relates to a wound healing device, and more particularly to a wound healing device which positions an energy delivery device into at least a portion of a wound and delivers energy to the wound.
  • Mechanical devices for effecting non-invasive compression of arteries include the use of pressure cuffs.
  • the cuff includes a strip of non- elastic material to be wrapped around a limb.
  • An elastic inflatable bladder is superimposed on the non-elastic material. When the bladder is inflated pressure exerted by all parts of the enwrapment on the limb is increased.
  • U.S. Patent No. 3,171,410 discloses a pneumatic dressing which exemplifies traditional pressure cuff devices.
  • One C-clamp device features a rigid footplate, as disclosed in U.S. Patent
  • U.S. Patent No. 3,625,219 discloses a transparent rubber membrane clamped to a transparent plastic plate to form an expandable pressure chamber. Clamping screws are used to maintain various members of the chamber support structure in place, and must be loosened to adjust the position of the chamber relative the area to which pressure is to applied.
  • the bladder is typically mounted on a pressure plate.
  • PSAs Pressure-sensitive adhesives
  • PSAs are used for a variety of industrial, consumer, and medical applications. PSAs are characterized as being normally tacky and exhibit instant tack when applied to a substrate.
  • a variety of polymers have been used to manufacture PSAs, for example acrylic and methacrylic ester homo- or copolymers, butyl rubber-based systems, silicones, urethanes, vinyl esters and amides, olefin copolymer materials, natural or synthetic rubbers, and the like.
  • a PCT publication WO91/14462 published October 3, 1991, refers to medical devices comprised of a substrate with a particular moisture vapor transmission rate with an adhesive thereon which is tacky at skin temperature but less tacky or not tacky at room temperature.

  • an object of the present invention is to provide a wound closure device that delivers energy to a wound.
  • Another object of the present invention is to provide a wound closure device that provides for the delivery of RF energy to a wound.
  • FIG. 1 illustrates the wound closure device of the present invention.
  • FIG. 2 illustrates the positioning of the wound closure device of FIG. 1 at a wound site.
  • a wound closure apparatus 100 of the present invention includes an energy delivery device 102 with an energy delivery surface 104 that is at least partially positionable in an interior of an incision or wound 106.
  • Wound healing device also includes a bioabsorbable conductive mesh 108, a shrinkable film 110, a temperature monitoring and control device 112, and an energy source 114.
  • Energy delivery device 102 may be an electrode.
  • Energy source 114 may be a battery strip. Suitable sources of energy include RF, light, resistive heating, ultrasound, microwave, and other electromagnetic energy sources. In another embodiment the energy source 114 is not physically coupled to shrinkable film 110.
  • Wound closure apparatus 100 includes a conductive mesh 108 which may be made of a bio-absorbable conductive material.
  • Conductive mesh 108 may be at least partially covered with bioactive substance, including but not limited to collagen glue, or other wound healing promotion materials, in combination with the application of energy.
  • RF energy is used.
  • 1 to 3 watts of energy is delivered to wound 106 and tissue is heated to a temperature in the range of 40 to 42 degrees Celsius for 48 to 72 hours.
  • Conductive mesh 108 is coupled to shrinkable film 110. Shrinkable film
  • conductive mesh 108 maintains conductive mesh 108 at least partially in wound 106 and may also provide a force pulling the skin together to approximate the sides of wound 106 and thus promote healing.
  • shrinkable film 110 may provide a tensile force and can be a uniaxially oriented rectangular film or an elastic film support member which can relax back to a predefined size (length and width). If the length to width ratio is small, a biaxially oriented film, such as a shrink wrap film, may be used, which is caused to relax to provide the desired force and inward tension across wound 106. In the case of a "circular" wound, a round biaxially oriented support is used. To create an inward tension, shrinkable film 110 is in a relaxed state and returns to its pre-oriented size and geometry. Because the oriented film "remembers" its initial state, a film that can shrink by a prescribed amount can be provided. This feature is a commonly specified property of shrink wrap tubing, where a 2:1, 2.5: 1, etc. shrink ratio is specified. For example, a 1 inch diameter shrink wrap tubing specified as a 2: 1 material will shrink to precisely 0.5 inches diameter after it is relaxed.
  • Suitable materials for shrinkable film 110 include polyethylene, such as Raychem CGPE-105, Cryolite D-940 (W.R. Grace), and polyvinyl chloride (PVC).
  • FIGURE 2 shows the actual placement of wound closure apparatus 100 across wound 106.
  • Arrows depict the tension force 202 applied to wound 106 in terms of a closure mechanism.
  • Low-powered resistive heating 204 speeds the healing process.
  • energy delivery devices 102 are coupled to shrinkable film 110.
  • Energy delivery devices 102 are coupled to conductive mesh 108.
  • energy delivery devices 102 are positioned in conductive mesh 108, which provides for the transfer of energy from energy delivery devices 102 through conductive mesh 108 to wound 106.
  • energy delivery devices 102 can be individually positioned within conductive mesh 108 and then coupled to energy source 114. The coupling can be through film 110 but it is not necessary. There are various embodiments for the positioning of energy delivery devices 102.

Abstract

Ce dispositif de cicatrisation de plaie se compose d'un support d'apport d'énergie que l'on peut au moins partiellement placer à l'intérieur d'une plaie. Ledit support est associé à un film qui est placé autour de la plaie. Apporter de l'énergie à la plaie fait cicatriser celle-ci.
