Definitions

  • the present invention relates generally for medical devices intended for treatment of scar formations caused by increased skin tension.
  • Scarring is a natural occurring biological process in living tissues appearing in response to acute or chronic injury as part of the wound healing stages. Most tissues and organs display both scarring and regeneration as natural responses to injury. However, the balance between those two responses varies between the different tissues. Cutaneous injury usually results in scarring and collagen deposition, which undergoes remodeling over months and years and therefore may change in size and color.
  • the present invention seeks to provide an improved medical device for preventing scar formation, as is described further in detail hereinbelow.
  • Figs. 1A and IB are simplified top-view and side-view illustrations, respectively, of a medical device for preventing scar formation, in accordance with an embodiment of the present invention
  • FIG. 2 is a simplified illustration of a medical device for preventing scar formation, in accordance with another embodiment of the present invention.
  • FIG. 3 is a simplified illustration of a medical device for preventing scar formation, in accordance with another embodiment of the present invention.
  • Fig. 4 is a simplified illustration of a medical device for preventing scar formation, in accordance with another embodiment of the present invention.
  • Fig. 5 is a simplified illustration of a medical device for preventing scar formation, in accordance with another embodiment of the present invention.
  • Fig. 6 is a simplified illustration of a medical device for preventing scar formation, in accordance with another embodiment of the present invention.
  • Increased tensile forces on wound site have been shown to be a key factor in forming abnormal scarring.
  • Such scar formation includes hypertrophic scars, keloids and widened scars.
  • Long-term prevention of such forces, using paper or microporous tape, has also been shown to decrease scar size.
  • the devices described herein are designed for preventing, decreasing or limiting the tensile forces affecting the cutaneous wound site, thereby improving scar morphology and appearance.
  • Device 10 includes a first layer 12 which is applied over the wound (and may overlap the wound from two or more sides).
  • First layer 12 may be paper, microporous or other soft sheet, suitably shaped and sized for efficient application on wound sites.
  • First layer 12 is provided with upper and lower adhesive surfaces 14 and 15, which may initially be covered with liners 16 and 17, respectively.
  • One non-limiting example is 3M double coated tape 9832.
  • First layer 12 does not have to be stretchable, but should be able to stay on the wound site for a prolonged time, such as a week.
  • Device 10 includes a second layer 18, which serves as a contracting element 18 for contraction of first layer 12.
  • Second layer 18 serves as a security tape for limiting tensile stress.
  • Second layer 18 has an adhesive surface 19, which may initially be covered with a liner 20.
  • a liner 20 is 3M MICROPORE TAPE 1530, which is a latex-free, hypoallergenic paper tape.
  • the liners of the layers may be of any size and number (one or more).
  • the contraction mechanism is thus an outer adhesive tape connected to the device which is used after application of the first layer 12 on the wound site, thereby contracting the first layer 12 in the axis of its placement.
  • the combination of the two layers 12 and 18 prevent the wound site from moving and thus does not allow increased skin tension, thereby preventing scar formation.
  • Second layer 18 may be stretched over first layer 12; second layer 18 may be smaller than or the same size as or larger than first layer 12.
  • the contracting element 18 is on one side of device 10.
  • the contracting element 18 includes one or more adhesive strips, which may be on more than one side of device 10. It is seen that the adhesive surface 14 includes discrete regions of adhesive, but the invention is not limited to this.
  • the contracting element 18 is a fastener type strip, such as VELCRO.
  • the contracting element 18 is a ratchet type contraction, wherein ratchet edges fit into apertures 22 formed in first layer 12.
  • Other mechanisms may be employed as well.
  • the device may be transparent or of colors similar to population skin tones and may have physical or chemical sunlight and UV blocking substances 24, impregnated or otherwise applied to or in the device, to protect the scar from excessive exposure to the sun.
  • the device may include or may be applied on a silicone sheet placed in such a way as to allow silicone contact with the wound site and remote attachment to the skin and contraction of the device.
  • the dressing may be impregnated with chemicals or pharmaceuticals 26 for slow release of substances promoting wound healing.
