Patent CA-2348678-A1 (CA)
Inventor: PENG SONG
IPC: G02B6/34
Filed: 2001-06-05
Abstract: An optical wavelength muter utilizes a dispersive medium (e.g., a diffraction grating) and reflective surfaces. The dispersive medium separates an input optical signal (light beam) into a plurality of components, for example by wavelengths. The reflective surfaces convert the components into separate output beams traveling in the desired directions. The number and the direction of the output beams can be controlled by manipulating the angle of incidence at which the components strike the reflective surfaces. A micro-mirror array modulator serves as the reflective surfaces.  Each mirror in the micro-mirror array modulator is positioned to direct individual components into a number of output signals.    Alternatively, a polarization steering device which includes a polarization modulator and at least one birefringent element in addition to reflective surfaces is utilized. A Wollaston prism with a reflective surface may also be used.

Title: Topical solutions for the treatment of nasal symptoms in the common cold for newborn infants, children and adults
Inventor: LEVY MAURICE
IPC: A61K31/573
Filed: 2001-10-19
Abstract: Common cold is a viral infection resulting predominantly in inflammation of the nasal mucosa. The most prevalent symptoms are nasal congestion (resulting in obstruction), and nasal discharge.   The solutions proposed are intended for topical intranasal use in newborn, infants, young and older children, and adults. The main ingredients concentration will vary according to the patient's age, effects and side effects observed during the studies.   The main ingredient of these solutions is the steroid, Bethamethasone or Dexamethasone.    These can be used alone or in combination with an Aminoglycoside antibiotic (Tobramycin or Gentamycin) and/or an anticholinergic agent, such as Ipatropium bromide.   The steroid will act as an anti-inflammatory agent and as such, will relieve nasal edema, congestion and obstruction. The anticholinergic agent will decrease nasal discharge through the parasympathetic nervous system. The antibiotic used may act on the nasal bacterial flora and its interaction with an infected, damaged nasal mucosa.

Filed: 2000-05-11
Abstract: The present invention is a balloon catheter used primarily in treatment and surgery for the purpose of dilating lesion sites such as strictures or blockages in passages in the human body. The balloon catheter of the present invention has a structure wherein a guide wire passing tubular member is deployed passing through the interior of the expansion body, and the outer surface of the tubular member and the expansion body are concentrically fused near the distal end of the catheter.  This is a balloon catheter that is characterized by the fact that the Shore hardness of the material configuring the outermost surface of the tubular member is smaller than the Shore hardness of the material configuring the expansion body. It is therefore possible to flexibly adjust the tip portion formed by securing the expansion body and the guide wire passing tubular member.
