  • Patent number: 5899026
    Abstract: The disclosure relates to building construction flashing materials that are presented in both liquid and solid form and is useful in new building construction as well as retrofit procedures. The liquid form is comprised of a silicone base which has been reformulated to improve its flowability and self-leveling qualities allowing it to be applied by brush, pump or spray apparatus. It can be used alone or it can serve as a complementary effective moisture barrier when used with the solid form of the elastomeric flashing materials. The solid form of the elastomeric flashing materials can be extruded sheet material, formed specialty accessories, and/or a readily formable metallic substrate material which has been completely coated with the reformulated liquid silicone, resulting in a highly bendable, formable and shape retaining flashing component.

  • Patent number: 5429117
    Abstract: An endoscopic system and method for performing endoscopic surgery at locations where tissue inserts into bone which includes a sleeve member, obturator, cutting and excision instruments, and a marking and insertion assembly wherein the sleeve member has an expanded portal through which instrument access and improved visualization can be performed at arcuate lines of insertion of tissue into bone. The sleeve member can include a flange for engaging tissue along the line of insertion and exposing the bone and measurement means for gauging precisely the reduction or resection of bone. An alternative embodiment of the sleeve member has a non-uniform aperture with an instrument portion and a register portion providing increased space and maneuverability for instruments when operating at the portal on tissue or bone that can include the flange. Cutting instruments are provided with an extension portion to extravasate from tissue and palpitate underlying tissue.

  • Patent number: 5400768
    Abstract: An endoscopic system and method for performing endoscopic surgery at locations where tissue inserts into bone which including a sleeve member for forming an opening in the body between tissue and bone having a tube, an instrument portion interconnected to a register portion, open ends, slot segments extending inwardly from said open ends, access opening for accessing the interface of tissue and bone, and an obturator configured for inserting slidably into the sleeve member and in the body between tissue and bone.
