Abstract: Elastomeric sheeting materials are described which are formed from the process of (1) creating a membrane comprising a semi-interpenetrating polymer network ("IPN") of polytetrafluoroethylene ("PTFE") and polydimethylsiloxane ("PDMS") by causing a matrix of PDMS to be formed in situ with a matrix of PTFE; (2) causing a surface of substantially pure PDMS to be formed on at least one side thereof; (3) allowing said PDMS compositions to vulcanize; and (4) converting said structure into useful shapes suitable for application to anatomical areas of the body. The product of the process is suitable for the treatment of dermatologic scars, such as those associated with traumatic or surgical injuries of the skin. The pure PDMS layer provides desired therapeutic effects. The semi-IPN membrane provides improved physical integrity, durability, and elastic behavior in comparison to prior art.
Abstract: A method and apparatuses are disclosed for determining an anticoagulant therapy factor (ATF), a corrected anticoagulant therapy factor (CATF), and a modified anticoagulant therapy factor (MATF), all selectively used for monitoring oral anticoagulant therapy to help prevent excessive bleeding or deleterious blood clots that might otherwise occur before, during or after surgery. The anticoagulant therapy factor (ATF), the corrected anticoagulant therapy factor (CATF), and a modified anticoagulant therapy factor (MATF) are based upon disclosed methods for determining the fibrinogen transformation rate (FTR) which, in turn, is dependent on a maximum acceleration point for fibrinogen (FBG) conversion. The ATF, CATF, and MATF quantities are also based upon the prothrombin time (PT), but have no need for the difficulty to obtain prior art International Normalized Ratio (INR) and International Sensitivity Index (ISI) parameters.
