Patent CA-2436520-A1 (CA)
Inventor: LEVIN JOHN M
IPC: A61M1/16
Filed: 2001-10-19
Abstract: Continuous internal peritoneal dialysis prosthesis (10) and method employing an abdominal sac (12) adapted to be retained in the abdominal region of a patient's body and including dialysate therein for permitting unconcentrated urine within the peritoneal region to pass through a semi-permeable membrane wall (56) of the abdominal sac (12). The unconcentrated urine within the abdominal sac (12) is directed through a section of the patient's bowel (18) and is communicated with the internal wall of the bowel (18) to thereby concentrate the urine. The concentrated urine is then directed into the urinary bladder (20) for subsequent excretion from the patient's body. In th e preferred prosthesis (10) and method of this invention the normal breathing pattern of the patient is employed to assist in the circulation of the unconcentrated urine from the abdominal sac (12) into and through the sectio n of the patient's bowel (18). In alternative embodiments, the dialysate may b e contained within the abdominal sac (12), contained within the prosthesis (10 ), or allowed to directly contact the peritoneum. Moreover, in a further embodiment, an abdominal sac is omitted and the peritoneal region of the bod y retains the dialysate and unconcentrated urine.

Title: Method and apparatus for detecting arterial stenosis
Inventor: PALTI YORAM
IPC: A61B8/06
Filed: 2002-02-28
Abstract: A high-speed non-invasive method and aparatus for detecting and measuring arterial stenosis without requiring imaging is disclosed. A Doppler ultrasound system automatically and repeatedly scans an area of interest to construct at least one velocity profile through segments of arteries over an area of interest. The velocity profiles and delta velocity profiles are automatically analyzed to determine a number of parameters indicative of potentially stenotic areas within the artery. These parameters may include: i) the average or peak velocity across the velocity profile; ii) the peak delta velocity across the velocity profile; iii) blund flow present in the velocity profile;  iv) turbulence in the blood flow; and v) the degree of skew in the velocity profile; iv) turbulence in the blood flow; and v) the degree of skew in the velocity profile. The delty velocity profile defined as the change in the velocity profile with respect to the length of the artery is used to examine how the above parameters change along the length of the artery. The parameters and their changing value along the length of the artery indicative of stenosis are detcted and compared with predefined threshold values to determine potentially stenotic areas. Scanning by the Doppler ultrasound system is triggered at a predefined point in an ECG cycle of the patient.

Patent CA-2443940-A1 (CA)
Inventor: HUGUES CHRISTIAN
IPC: B64C23/06
Filed: 2002-04-09
Abstract: A device having the form of a cylindrical spiral cavity and/or incorporating a helicoidal slot, making it possible to reduce induced drag and marginal swirl (vortex) and increase drag/lift ratio. Integrated with the wingtip or articulated on the wingtip, it can be adapted for all airfoils, in particular the wings of airplanes and gliders, helicopter blades and the tips or tractor or pusher airscrews, wind-powered generator blades and for surface vessels or submarines where lift or direction is used in triple axis (vertical, horizontal, and yaw) displacement. Used in a reverse configuration (undersurface/upper surface) on high speed land vehicles or racing cars, this device, when secured to the tip of each wing, produces a result inversely proportional to speed. The faster the vehicle is traveling, the less drag it generates and greater its ground adhesion.

Abstract: The present invention concerns a method for producing a wall or partition construction with essentially smooth surfaces. The method comprises the arrangement of opposite former sheets 8, 9 or equivalent surfaces at a distance from each other in order to form a former space with the aid of form ties 1, parts of which are caused to extend through holes 7 in the former sheets 8, 9 and provided with stop means 13, which are caused to come into contact with those surfaces of the former sheets 8, 9 that face the former space, and which form ties 1 are provided with retainers 4 on the surfaces of the former sheets 8, 9 that face away from the former space in order to maintain the former sheets 8, 9 or equivalent at a distance from each other, after which mortar or concrete in liquid form is added to the former space and caused to solidify. The form ties 1 are constituted by non-rusting material and are provided before application in the former space with breakage guides 13', which are located essentially in the plane of the inner surfaces of the former sheets 8, 9. The form ties 1 are caused to interact with supports and spacers 14 of non-rusting material, which are arranged to be in contact with the inner surfaces of the former sheets 8, 9. The supports and spacers 14 are designed such that they allow the mortar or concrete in liquid form to be caused to surround them except for those parts that are in contact with the inner surfaces of the former sheets 8, 9, the surfaces that face the former space. Following the solidification of the wall or partition construction, the retainers 4 and the former sheets 8, 9 are removed and the form ties 1 are broken at the breakage guides 13'. The invention also concerns a form tie 1 to be used when producing a wall or partition construction by the method described above.
