Title: Methods of thrombolytic organ treatment and repair
Inventor: BATTJES-SILER DEBRA J
IPC: A01N1/02
Filed: 2001-08-24
Abstract: The invention teaches methods and compositions for removing thrombi lodged in the microvasculature of an organ. To remove the thrombi, the organ may be perfused, flushed or washed with a suitable perfusion solution to which a sufficient amount of a thrombolytic agent, such as Streptokinase, has been added. The perfusing, flushing or washing process of the organ with the thrombolytic agent will promote thrombolysis on existing thrombi, prevent the formation of new thrombi in the organ, and/or open the vasculature of the organ thereby decreasing vascular resistance and increasing flow. The method of the invention may be practiced using an organ perfusion apparatus that would allow the viability of the organ to be sustained and/or restored upon perfusion with a thrombolytic agent.

Patent CA-2423167-A1 (CA)
Inventor: CHOI WOOHYEK
IPC: A61B5/053
Filed: 2001-09-18
Abstract: An improved system for monitoring the status of an IMD such as medical electrical lead during an implant procedure is provided. The system includes a signal generator for supplying a first signal such as a constant current or voltage to the IMD. A resulting voltage or current signal is generated, respectively, and may be sensed as an indication of the impedance of a portion of the body that is proximal to one or more electrodes carried by the lead.  This impedance indication is converted to an audible signal having a frequency that is proportional to the amplitude of the impedance indication. The pitch of the audible signal therefore rises when measured impedance increases, and drops as the impedance decreases. These pitch changes allow a user to determine positional information associated with the IMD, including the degree of lead tissue contact and extent of fixation of a device to tissue.

Title: A method for stabilizing vinyl aromatic monomers using selected polymerization inhibitors and polymers prepared therewith
Inventor: MERRILL JAMES T
IPC: C07C7/20
Filed: 2003-03-24
Abstract: Disclosed is the observation that 7-aryl-quinone methides and 4-tert-butylcatechol, when used in combination in a vinyl aromatic monomer to inhibit polymerization, do not inhibit polymerization to the same extent as each would if used separately. Stated another way, a phenomenon has been observed that when these two compounds are used together, they can, to a large extent, render each other unable to inhibit polymerization in a vinyl aromatic monomer. Also disclosed are methods of preventing adverse results of this interaction when undesired and a method of using this interaction to prepare a reactive vinyl aromatic monomer having a concentration of 4-tert-butylcatechol that would otherwise inhibit polymerization. The invention is disclosed to be useful with the production and storage of any vinyl aromatic monomer and is disclosed to be particularly useful with the production and storage of styrene monomer.

Filed: 2001-11-28
Abstract: A method and apparatus for method for discriminating heart rhythms includes computing a first predetermined number of RR intervals from received QRS  intervals, and computing a median RR interval corresponding to a predetermined number of the first predetermined number of RR intervals. A predetermined beat-to-beat variation and a corresponding predetermined count are determined based on the computed median RR interval. Beat-to-beat variation differences between the first predetermined number of RR intervals are computed and a determination is made as to whether the computed beat-to-beat variation differences are greater than the predetermined beat-to-beat variation, and as to whether a number of the computed beat-to-beat variation differences that are greater than the predetermined beat-to-beat variation is greater than the predetermined count. The heart rhythm is identified as an irregular rhythm in response to the number being greater than or equal to the predetermined count.
