A radio-frequency surgical implement detection system detects surgical implements in a surgical wound during and at the completion of a surgical procedure. Surgical implements, including surgical sponges or laparotomy pads, gauze pads and metallic surgical instruments, are individually attached to a non battery-powered, encapsulated radio-frequency marker. The marker comprises an integrated chip having a burnt-in memory code, which is broadcast through an antenna using a modulated carrier frequency. The code is received by an interrogating antenna of a detector. The interrogating antenna provides a power pulse, which is received by the antenna of the radio-frequency marker. The power pulse charges a capacitor, which proves power for the read function, carrier frequency modulation function and broadcast function of the integrated chip, permitting each marker-containing implement to be specifically identified.

ClotFoam is a surgical sealant and hemostatic agent designed to be used in cases of non-compressible hemorrhage. It can be applied in the operating room through laparoscopic ports, or directly over lacerated tissue in laparotomy procedures or outside the operating room through a mixing needle and / or a spray injection method following abdominal, chest, extremities or other intracavitary severe trauma to promote hemostasis. Its crosslinking technology generates an adhesive three-dimensional polymeric network or scaffold that carries a fibrin sealant required for hemostasis. When mixed, Clotfoam produces a foam that spreads throughout a body cavity reaching the lacerated tissue to seal tissue and promote the coagulation cascade.The viscoelastic attachment properties of the foam as well as the rapid formation of a fibrin clot that ensure that the sealant remains at the site of application without being washed away by blood or displaced by movement of the target tissue .

A prosthetic mesh and method of use in surgical methods for closure of abdominal incisions and prosthetics for repair of ventral hernias. The mesh provides for a new prosthetic that can be used for closure of laparotomy incisions, in patients at high risk for hernia formation, and in the repair of existing ventral hernias. The mesh utilizes existing multi laminar technology for intra peritoneal mesh, and fashions it in the shape of an intact Rectus Sheath. The mesh matrix can be made of any of the various absorbable or permanent polymer filaments that are woven or knitted into a scaffold for added strength to the abdominal wall closure during the healing phase, and for delivery of bio active substances that contribute to a biochemical milieu that contributes to favorable healing. A permanent non absorbable prosthesis will be desirable in certain circumstances and for particular patients, a slowly dissolving mesh would be ideal in most cases. The absorption of the prosthesis must be slow, approximately one to two years, thus giving enough time to preserve support for the healing abdominal wall repair, as this is the period of time over which most incisional hernias present.
