Definitions

  • the stabilizing structure inhibits the filler material from collapsing along its height dimension, while enabling the filler material to collapse within the plane defined by the wound margins. This is useful in the case of abdominal surgery, for example, in which the surgical incision is along a straight line and opens laterally to form an oval shaped wound. This generally oval shaped wound can extend through muscle and fatty tissue having variable mechanical properties. Wound healing is better served through the use of an oval shaped structure adapted to preferentially collapse towards the original line of incision. In preferred embodiments, the stabilizing structure promotes collapse of the filler material in a manner to effect
  • Fig. 6 illustrates an enlarged view of a preferred embodiment of the tissue anchor system in accordance with the invention.
  • Fig. 1 IB illustrates a top view of a wound closure device and a tissue adhesion device.
  • Fig. 11C shows a detailed perspective of a surgical drainage system in accordance with a preferred embodiment of the invention.
  • tissue grasping surface 104 Extending over at least one surface of the filler material 102, and preferably extending over an outer perimeter surface of the filler material 102 is a tissue grasping surface 104.
  • the tissue grasping surface 104 is a flexible covering, such as a mesh film, that is secured to the outer perimeter surface of the filler material 102 and can expand and contract with the expansion and contraction of the filler material 102.
  • the tissue grasping surface 102 is a mesh film or a composite polyester mesh film, such as the Parietex mesh from Covidien (Mansfield, MA).
  • the tissue grasping surface 104 includes a plurality of outward-facing tissue anchor elements 106, which in the preferred embodiment are a plurality of closely-spaced barbs, hooks or tissue grasping elements, which can be integrally formed in the mesh film.
  • the filler material 102 is configured to exhibit preferential collapse characteristics.
  • portions of the filler material 102 can be made from more rigid material than the surrounding material, causing the filler material to preferentially collapse in a particular direction.
  • the filler material 102 can include a stabilizing endoskeleton made from a suitable rigid material embedded within a "collapsible" filler, such as an open cell foam.
  • a stabilizing endoskeleton made from a suitable rigid material embedded within a "collapsible" filler, such as an open cell foam.
  • the amount of applied negative pressure can be adjustable depending on the size and shape of the wound. Pressures above 125 mm, to as much as 250 mm or more can be used to assist in wound closure. The pressure can be reduced over time as the wound contracts. As shown in Figs.
  • Fig. 4C illustrates the wound 200 following the application of a negative pressure to the wound closure device 100.
  • the tissue anchor elements 106 grab the tissue margins 203 and cause displacement of the tissue margins 203 as the filler material 102 collapses.
  • the filler material 102 collapses in the x- and y- directions in such a manner as to reapproximate the tissue at the wound margin 203.
  • the crosshatched configuration of the stabilizer elements 108 help control the direction of tissue displacement during collapse.
  • the largest amount of tissue displacement in this embodiment is in the central region of the wound 200, where the opening 201 is widest, and this displacement is primarily inward along the x-direction. Away from the central region (e.g., at the top and bottom of the wound as shown in
  • the filler material is formed by mixing together appropriate metered amounts of constituent substances, (e.g., isocyanates, polyols, catalysts, surfactants, blowing agents and the like in the case of polyurethane foam), dispensing the reacting mixture into a mold, and then curing and demolding the material.
  • the material can then be cut or trimmed to the finished shape.
  • the endoskeleton support structure is assembled and placed into the mold, and the filler material is molded around the endoskeleton.
  • a method of performing a surgical procedure 800 using a wound closure device in accordance with preferred embodiments of the invention as illustrated in Fig. 10A After preparation 800 of the patient for surgery, an incision is made 820 to expose the surgical site, typically in the abdomen. After the procedure is performed, the wound is prepared 830 for closure. The proper size and shape of the wound closure device is selected 840 with the peripheral tissue attachment members positioned around the circumference or outer wall surface of the device. The device is inserted 850 into the wound and the tissue attachment elements are inserted 860 into the tissue. Negative pressure is then applied 870 to exert a closure force on the wound edges.
  • a wound incision 900 in which tissue region 906,908 have been separated to access an underlying tissue region 902 for treatment.
  • the lateral displacement of regions 906, 908 from their respective positions overlying region 902 has caused further separation between the displaced regions 906, 908 and the underlying structure.
  • the underlying structure can be the large and small intestines, which can be subject to infection and/or elevated fluid pressure.
  • the compressible wound closure element 918 is inserted followed by sealing drape 905 and the closer device 940 and fluid control tube 942.
  • the pad 907 operates to drain fluid 910 from the abdominal cavity by negative pressure through elements 925 and 918.
  • FIG. 18A-18B different force profile configurations for individual protrusions or elements 2103 A are depicted.
  • the protrusion 2103A is configured to resist compression of the associated stabilizer elements 2108 of the structural element 2101 in both x and y directions.
  • the protrusion is configured to provide uniform tensile forces to the stabilizing structure 2101, e.g., during the collapse thereof, in both the x and y axis.
  • the protrusion 2103A is configured to provide greater compression resistance of the associated stabilizer elements 2108 of the structural element in the y direction than in the x direction.
