Patent CA-2303021-C (CA)
Inventor: PARKER MARK P
IPC: A61B18/14
Filed: 1998-09-11
Granted: 2006-05-30
Abstract: A catheter (10) includes a plurality of primary leads (30) to deliver energy for ligating a hollow anatomical structure (52). Each of the primary leads (30) includes an electrode (34) located at the working end (15) of the catheter (10). Separation is maintained between the primary leads (30) such that each primary lead (30) can individually receive power of selected polarity. The primary leads (30) are constructed to expand outwardly to place the electrodes (34) into apposition with a hollow anatomical structure (52). High frequency energy can be applied from the leads (30) to create a heating effect in the surrounding tissue of the anatomical structure (52). The diameter of the hollow anatomical structure (52) is reduced by the heating effect, and the electrodes (34) of the primary leads (30) are moved closer to one another. Where the hollow anatomical structure is a vein (52), energy is applied until the diameter of the vein (52) is reduced to the point where the vein (52) is occluded. In one embodiment, a balloon (64) is inflated to occlude the structure (52) before the application of energy. Where the structure is a vein (52), the inflated balloon (64) obstructs blood flow and facilitates the infusion of saline, medication, or a high-impedance fluid to the vein (52) in order to reduce the occurrence of coagulation and to improve the heating of the vein by the catheter (10). The catheter (10) can include a lumen (48) to accommodate a guide wire (53) or to allow fluid delivery.

Abstract: An improved the velocity fuse valve controls communication between first and second brake valves and first and second brake lines. The velocity fuse valve includes a valve housing having a valve bore which slidably receives a valve spool. The spool moves in response to pressure in first and second pilot chambers, each communicated with a corresponding first and second outlet. The first pilot chamber is communicated with the first outlet via a first dashpot passage and a first orifice, and the second pilot chamber is communicated with the second outlet via a second dashpot passage and a second orifice. The orifices reduce or control how fast the spool will move in response to the pressure differential between the pilot chambers.

Abstract: A flame retardant, electrically-conductive EMI shielding material and method, the material being particularly adapted for use in fabric-over-foam EMI shielding gasket constructions. In construction, a generally planar, porous fabric member is provided as having at least an electrically-conductive first side and a second side defining a thickness dimension therebetween. A curable layer of a fluent, flame retardant composition is applied under a predetermined hydrodynamic pressure and viscosity to at least a portion of the second side of the fabric member. The hydrodynamic pressure and viscosity of the composition are controlled to delimit the penetration of the layer into the fabric member to a depth which is less than the thickness dimension of said fabric member. The layer then is cured to form a flame retardant surface coating on the second side of the fabric member such that the first side of said fabric member remains electrically-conductive.

Granted: 2007-11-13
Abstract: A compression release mechanism for an internal combustion engine wherein a rotatable pin positioned axially parallel to the camshaft is rotatably received in the cams, and has a lift member mounted at an axial end thereof. The pin is non- cylindrically shaped at one axial end thereof, and the non-cylindrically shaped end is received and secured into a correspondingly shaped bore disposed in a cylindrical hub extending perpendicularly from a one-piece flyweight. An optional adhesive can be used to secure the pin to the hub of the flyweight. According to a further optional embodiment, the hub can be crimped so as to engage the release pin. The disclosed configuration ensures a secure engagement and therefore avoids slipping between the release pin and the flyweight. Further, the design facilitates easy alignment of the pin with the flyweight during assembly. The flyweight can be a one-piece integral structure.

Abstract: A method of protein engineering is provided wherein a searchable computer database is created comprising entries in the form of descriptions of a location and orientation in 3D space of side chains of the constituent amino acid residues of a framework protein. A query is created which corresponds to a description of a location and orientation in 3D space of respective side chains of amino acid residues of a sample protein. The location and orientation in 3D space of constituent side-chains is preferably described as a C.alpha.-C.beta. vector. The query is used to search the database and thereby identify a hit which corresponds to a framework protein having structural similarity with said sample protein. Framework protein "hits" so identified may be suitable candidates for further modification. A particular advantage of the present invention is that a modified framework protein may display one or more desired characteristics, such as a function similar to or inhibitory of the sample protein.

Title: Monolithic high performance miniature flow control unit
Inventor: CHRISTIANSON HARLOW B
IPC: A61M5/36
Filed: 2000-04-04
Granted: 2008-09-02
Abstract: A monolithic flow controller (10) for controlling the rate at which a medicinal liquid (14) is administered to a patient. The monolithic flow controller (10) includes one or more virtual valves (26) that, because of their relatively small opening size (less than 0.5 µm in diameter), only permit fluid to flow through the valve (26) when a forward bias voltage is applied. If a reverse bias voltage or no voltage is applied, fluid flow through the opening is inhibited. The fluid rate through the device (10) is monitored using two pressure sensors (38, 40) or a differential pressure sensor that determine the differential pressure along the flow path through the device or relative to the external ambient pressure. The flow through the device is equal to the product of the differential pressure and the conductance of the channel (24) in the flow controller. A capacitive bubble sensor (34, 36) is optionally provided to detect bubbles in the medicinal liquid being administered to the patient. The flow controller (10) can be made sufficiently small to be injected into a patient's cardiovascular system or other portion of the patient's body through a hypodermic syringe and needle, or it can be implanted in the patient's body at a desired site. The medicinal liquid (14) can be contained within an integral pressurized fluid reservoir (12), administered by gravity feed, or conveyed by a pump to an inlet port (16) of the flow controller (10).
