Title: Electrosurgical device having a dielectric seal
Inventor: SARTOR JOE D
IPC: A61B18/00
Filed: 1999-09-21
Abstract: An electrosurgical device is provided having at least one elastomeric seal capable of providing bio-contamination and dielectric protection by inhibiting the ingress of fluids and contaminants through the nose and actuator areas. The elastomeric seal is manufactured from a thermoplastic elastomer or resin which while in liquid form is placed within a mold. A housing section having the main circuit components and mechanisms of the electrosurgical device is then placed within the mold. Once the elastomer cures, the elastomeric seal seals the components and mechanisms within the housing partial-section. The elastomeric seal defines a flexible first opening at a distal end of the electrosurgical device to accommodate varying diameters of electrodes or blades connected to the nose area of the elctrosurgical device. An actuator seal is also provided on the actuator area of the electrosurgical device to prevent fluids and contaminants from entering the electrosurgical device through the actuator area. The device is further provided with a plug connector having a counting mechanism for counting the number of times the device is plugged into an electric generator.  A disable mechanism is included at the proximal end of the plug connector to disable the device after a pre-determined number of operations.

Abstract: The present invention relates to identifying protein epitopes and more particularly to a novel method for identifying, determining the location, optimal length of amino acid residues and immunobiological potency of protei n epitopes by fitting a hydrophilicity and/or hydrophobicity plot generated fo r the amino acid linear sequence of a polypeptide to a mathematically generate d continuous curve thereby generating at least one set of potential epitopes which include ranked potential epitopes having a specific number of amino ac id residues. The immunobiologically-active linear peptides are deemed the potential epitopes that exhibit the most alternating positioning about an equilibrium position when juxtaposed on the hydrophilicity and/or hydrophobicity plot and their optimal length corresponds to the specific number of amino acid residues in the set of ranked potential epitopes. The amino acid sequence of the protein epitopes of the present invention exhibit  a hydrophobic-hydrophilic-hydrophobic motif.

Abstract: A laminate packaging material for use with food products, and a retortable pouch comprising that material, are disclosed. The laminate material includes an outer polyethylene terephthalate layer, a nylon second layer, and a polypropylene inner layer. A solventless adhesive is used to bond the layers together. The solventless adhesive includes surface-modified exfoliated montmorillonite clay platelets. The platelets lie generally parallel to the plane of the laminate, and overlap to form a barrier to oxygen and other volatile materials. The retortable pouch is formed by heat sealing the edges one of more sheets of the laminate such that the polypropylene layers face inward and are welded together. The pouch and its contents can then be pasteurized by heat-treatment without degradation of the laminate or the heat seal.
