Wound closure methods and apparatus are provided which utilize blood fluid by activating the clotting cascade of blood fluid outside the body within a substantially enclosed sterile container then introducing the blood fluid to the wound site to complete clotting. Methods and apparatus for providing ways of inhibiting anti-coagulating agents and slowing fibrin clot degradation are also disclosed. Kits for practicing the invention singularly or in combination with and/or associated with preferred procedures are also disclosed. The present invention provides improved methods of creating hemostasis or control of bleeding at the site of wounds, particularly wounds created in arteries during procedures employing percutaneous access. The invention preferably includes the steps of acquiring an aliquot of a patients blood, i. e. , autologous blood, removing a negatively charged anti-coagulating agent, preferably heparin, from the blood, and preferably initiating the bloods natural clotting cascades and transporting the thus treated blood to the site of the wound where the clotting cascade will be completed producing a clot at the wound site that will create a condition of hemostasis.

A color-tailorable, surface-metalized, pigmented optical body comprising a single or multiple layer polymeric core comprising at least one layer of a thermoplastic polymer material having dispersed therein a particulate pigment, and a metallic layer located on at least one outer surface of the polymeric core. The optical bodies are generally constructed such that the at least one of the L*, a*, and b* color scales of the polymeric core differs from the L*, a*, and b* color scales of the metallic layer.

An optical film includes a reflective polarizing element and a particle-containing layer. The reflective polarizing element substantially reflects light having a first polarization state and substantially transmits a second polarization state. The particle-containing layer is disposed on the reflective polarizing element and in a same optical path as the reflective polarizing element. The particle-containing layer is configured and arranged to transmit light and includes a plurality of particles that roughen an exterior surface of the optical film. Preferably, using the optical film in an optical device does not substantially reduce the gain advantage of the optical device when compared with an optical device utilizing the same optical film without particles in the surface layer. Also described are optical devices using the optical film and methods of making and using the optical films.

Color-stable, pigmented optical bodies comprising a single or multiple layer core having at least one layer of a thermoplastic polymer material. The thermoplastic polymer material has dispersed within it a particulate pigment. The optical bodies generally possess high clarity and low haze and exhibit a transmission of light within a wavelength band of interest within the visible spectrum of from about 10 to about 90 percent. The optical bodies also comprise one or more dyes in an amount sufficient to adjust transmitted color, by no more than about 15 units of the color coordinate a* and no more than about 15 units of the color coordinate b*, to a target color such as neutral gray.

A wound closure apparatus and associated methods are provided which utilize blood fluid by activating the clotting cascade of blood fluid within a substantially enclosed sterile container then introducing the blood fluid to the wound site to complete clotting. An apparatus for providing ways of inhibiting anticoagulating agents and slowing fibrin clot degradation are also disclosed. Kits are also disclosed. The invention provides a clotting cascade initiation apparatus including a substantially enclosed sterile containment chamber within which an aliquot of blood fluid, either autologous or from donor sources, can be received and retained. In preferred embodiments, the sterile containment chamber further includes a heparin binding agent which will bind heparin and remove it from the blood fluid. In further embodiments, the containment chamber will also include a procoagulating agent, wherein a clotting cascade can be initiated when the blood fluid is accepted into the sterile containment chamber.
