Granted: 1998-08-18
Abstract: Implantable therapy systems are disclosed for the local and controlled delivery of a biologically active factor to the brain, spinal cord and other target regions of a subject suffering from a dibilatating condition. The method of the invention involves surgically exposing an insertion site, generally located above a predetermined treatment site (12), in a patient. A cannula (20), having an obturator (30) positioned therein, is inserted at the insertion site, defining a pathway to the treatment site. The cannula (20) is preferably a low friction polymeric material such as polytetrafluoroethylene. The cannula (20) generally has an open proximal end for receiving the obturator (30), and an open distal end, preferably a tapered end, for delivery of neurologically active factors to the treatment site (17). The obturator (30) is then removed from the cannula (20), and a biocompatible tethered vehicle (40) containing a biologically active material is inserted into the cannula along the passageway. A guide wire (32) can be inserted within the cannula, behind the vehicle (40), to position the proximal end of the vehicle at the proximal tip of the cannula (20b). Once the vehicle (40) is positioned near the proximal end of the cannula (20), the cannula is removed from the passageway, followed by the guide wire (32), leaving the vehicle (40) positioned at the treatment site (12);

Granted: 2002-06-25
Abstract: A digital video quantizer for use in TCAS and ATCRBS/SIF systems. A digital delay receives a digitized video signal and produces a plurality of delayed digital signals which are used throughout the quantizer. A threshold generator then produces a predetermined threshold and a dynamic threshold, and a quantized video generator compares one of the delayed digitized signals to a threshold to produce a quantized video signal. A slope quantizer detects a slope of the digitized signal which exceeds either a positive or negative threshold. In addition, a rise time detector detects an excessive rise time in the digitized video signal, and a chip amplitude comparator provides a signal which is used in detecting Mode S  data bit values. The digital video quantizer's use of digital references rather than analog references, eliminates the inaccuracies caused by a reference voltage varying over time or temperature. The digital references also facilitate modification of the reference values at a later time.

Title: Immunometric determination of an antigen or hapten
Inventor: PRADELLES PHILIPPE
IPC: G01N33/543
Filed: 1994-01-13
Granted: 2007-04-24
Abstract: The invention relates to a process for the immunometric determination of an antigen or hapten.      According to this process, contacting takes place (fig. 1A) between the antigen or hapten (3) to be determined and the antibodies (2) fixed to a solid phase in order to immunologically bond the antigen or hapten with the antibody. This is followed (fig. 1B) by immobilizing the antigen or hapten (3) by a covalent bond (4) to the solid phase (1) whilst releasing its epitope (fig. 1C). This is followed by the contacting thereof (fig. 1D) with labelled antibodies (5) and determination takes place (fig. 1E) of the quantity of fixed labelled antibodies in order to deduce therefrom the initial hapten or antigen concentration.      As a result of this stage of immobilizing and releasing the epitope, a high sensitivity is obtained using a single antibody.
