Patent CA-2407051-A1 (CA)
Inventor: O'LEARY DAVID
IPC: G06M1/24
Filed: 2001-06-23
Abstract: A de-agglomerator is provided for use with a breath-actuated dry powder inhaler for breaking up aggregates and micronizing particles of dry powder prior to inhalation of the powder by a patient using the inhaler. The de-agglomerator includes an inner wall defining a swirl chamber extending along an axis from a first end to a second end, a dry powder supply port, an inlet port, and an outlet port. The supply port is in the first end of the swirl chamber for providing fluid communication between a dry powder delivery passageway of an inhaler and the first end of the swirl chamber. The inlet port is in the inner wall of the swirl chamber adjacent to the first end of the swirl chamber and provides fluid communication between a region exterior to the de-agglomerator and the swirl chamber. The outlet port provides fluid communication between the second end of the swirl chamber and a region exterior to the de-agglomerator, whereby a breath induced low pressure at the outlet port causes air flows into the swirl chamber through the dry powder supply port and the inlet port. The air flows collide with each other and with the wall of the swirl chamber prior to exiting through the outlet port, such that any powder entrained in the air flows is broken down and micronized. The de-agglomerator further includes vanes at the first end of the swirl chamber for creating additional collisions and impacts of entrained powder.

Title: Improved safety cryotherapy catheter
Inventor: WILLIAMS RICHARD S
IPC: A61B17/00
Filed: 2001-07-03
Abstract: Improved devices, systems, and methods for inhibiting hyperplasia in blood vessels provide controlled and safe cryotherapy treatment of a target portion within a body lumen of a patient. Efficacy of endoluminal cryogenic cooling can be enhanced by limiting cooling of target tissue using a thermal barrier disposed between a dual balloon cryotherapy catheter. Containment of both balloons can be monitored by applying a vacuum within a space between the first and second ballons, and by coupling the vacuum space to a fluid shutoff so as to inhibit flow of cryogenic fluid in response to a change in the vacuum space. Controlled cooling of the vessel can be improved by use of a nebulizer in fluid communication with a cryogenic liquid lumen and a gas supply lumen.

Title: Transport drawbar
Inventor: OLSON BRIAN
IPC: B21D53/88
Filed: 2003-03-03
Abstract: A transport drawbar for an agricultural tractor has an elongate forward drawbar section of substantially uniform rectangular cross section that mounts on the tractor in the conventional way. An elongate second drawbar section extends to the rear from the forward section. The second drawbar section has the same thickness as the forward drawbar section and a substantially greater width. A trailing drawbar section extends to the rear from the second drawbar section, the trailing drawbar section having the same thickness as the forward and second sections and a width substantially the same as the width of the forward section. Two tapering transition sections are provided between the second drawbar section and the forward and trailing drawbar sections respectively. Two angular offsets are formed in the second drawbar section such that the trailing drawbar section is parallel to and offset downwardly from the forward drawbar section. This drawbar can be used as a conventional tractor drawbar for pulling implements in the field. It also has sufficient strength and stiffness that it can be used for transporting bulk cargo. The drawbar is manufactured by flame cutting a blank for the drawbar and die forming the angular offsets in the blank. The formed blank is heat treated. Pivot pin holes are formed in the forward section of the blank and a draw pin hole in the trailing section. The blank is then quenched and shot peened.

Title: Method and apparatus for efficient high-resolution visual field mapping
Inventor: ULLMAN SHIMON
IPC: A61B3/024
Filed: 2001-10-09
Abstract: A micro-perimeter technique using a portable computer (10) and a projector (12), and using two screening (14) methods, multi-resolution static and bi-directional kinetic. The static method, as applied to a static test, starts with relatively low-resolutions, and only the unseen zones are selectively remapped under higher resolutions during successive iterations. The bi-directional kinetic method, as applied to a kinetic test, uses a response to a continuously moving target, and the unknown response delay is compensated for by an algorithm that merges the patient's response to measurement at the same visual location, but with opposite scanning directions. Offline visualization of the mapping results is performed automatically superimposed over the fundus image.
