Patent CA-2331437-A1 (CA)
Inventor: ZOLTEN A J
IPC: G02C7/04
Filed: 1998-12-17
Abstract: Dans le cadre de cette méthode de rééducation ou d'apprentissage de zones ciblées du cerveau, on utilise des demi-lentilles (50) comprenant des secteurs radiaux semi-opaques (51, 53) qui permettent d'aveugler de manière sélective des parties des régions cérébrales du système visuel de traitement de l'information et ce, afin de forcer une partie spécifique du cerveau qui est alors stimulée à procéder à ce traitement de l'information. Dans cette rééducation, le patient doit exécuter des tâches d'ordre visuel et non visuel conçues pour activer le traitement de l'information dans la partie ciblée du cerveau. On emploie une série de demi-lentilles (50) dont la transparence s'accroît progressivement pour permettre au système visuel du patient de s'adapter par étapes jusqu'à ce que soit restauré l'équilibre entre une capacité intacte de traitement de l'information visuelle et une capacité de traitement réapprise.

Patent CA-2339657-A1 (CA)
Inventor: OSTROVSKY ISAAC
IPC: G02B23/24
Filed: 1999-08-18
Abstract: An optical scanning and imaging system and related method for scanning and imaging an object is disclosed. The scanning and imaging system does not use mechanically moving components to achieve lateral scanning of an object.  Instead, the system includes a deflecting prism comprised of a material having an index of retraction that varies with changes in an applied electromagnetic field and that remains substantially constant with changes in wavelength of incident light within a predetermined wavelength range. An optical fiber transmits light within a predetermined wavelength from a light source through a gradient index lens which sends a collimated beam of light to the prism. Due to the unique properties of the prism, the light is deflected at a substantially constant angle within a lateral scanning plane. The scanning system is adapted to be used for medical imaging by disposing it within a distal end of a catheter.

Title: Traction force sensing vacuum extractor
Inventor: SMITH STEVEN R
IPC: A61B17/30
Filed: 1999-11-30
Abstract: A vacuum extractor (100) for use in childbirth is described. The vacuum extractor (100) includes a handle (110), and a vacuum cup (120) with a force sensor (130) coupled to the vacuum extractor (100).
