InactiveUS20070185474A1Reduce heatProtect from preventable damageLaser detailsEndoscopesMedicineVaporization
Laser radiation delivered to a treatment area causes vaporization of a substantially greater volume of tissue than the volume of residual coagulated tissue. The laser radiation may have a wavelength of about 300 nm to about 700 nm, may be used with a smoke suppressing irrigant, may have an average irradiance greater than about 5 kilowatts / cm2, and may have a spot size of at least 0.05 mm2. A laparoscopic laser device, for use with an insufflated bodily cavity, may include an elongate body adapted for insertion into an insufflated bodily cavity. A laser energy delivery element, at the distal end of the elongate body, may be coupleable to a source of tissue-vaporization-capable laser energy and capable of delivering laser energy along a laser energy path extending away from the laser energy delivery element. A smoke-suppressing liquid pathway, extending along the elongate body to an exit opening at the distal end, may be coupleable to a source of a smoke-suppressing liquid. The smoke-suppressing liquid is directed generally along the laser energy path. A remote visualization device may be used to view along the laser energy path.

Tissue sealant for use in non-compressible hemorrhage

ClotFoam is a sealant and hemostatic agent for use in cases of non-compressible hemorrhage for moderate to severe bleeding. 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 intracavitary severe trauma or surgery. Its crosslinking technology generates an adhesive scaffold that carries a fibrin sealant required for hemostasis. Clotfoam produces a foam that spreads throughout a body cavity reaching the lacerated tissue to seal tissue and promote the coagulation cascade. The composition is biocompatible and non-inflammatory.The invention uses fibrin monomer polymerized by a change of pH as active sealing component. The viscoelastic properties of the foam as well as the rapid formation of a fibrin clot ensure that the sealant remains at the site of application without being washed away by blood.
