Title: Deflectable sheath for optical catheter
Inventor: ADAIR EDWIN L
IPC: A61B18/26
Filed: 1991-08-29
Abstract: Abstract An apparatus is provided having a steerable and removable sheath for use with an optical catheter wherein the sheath with the catheter therein is to be positioned in a pathway leading to a body cavity of a patient for observation and/or treatment.  The apparatus comprises an elongated, bendable, hollow body having a distal end, a proximate end and a plurality of channels extending from the proximate end to the distal end.  An optical catheter is extendable through one of the channels in the body having a distal and aligned with the distal end of the body and a proximate end extending outwardly beyond the proximate end of the body.  The catheter conforms to the shape and movement of the body.  A deflectable means is provided adjacent the distal end of the second of the channels to deflect the distal end of the body in a desired direction.  A substantially rigid wire is extendable through the second channel to straighten the body during insertion of the sheath in the passageway of the patient and for manipulating the deflectable means after insertion to deflect the body in a desired direction for examination and/or treatment.
Patent CA-2050691-A1 (CA)
Inventor: BISSELL ELLISTON P
IPC: G06Q20/00
Filed: 1991-09-05
Abstract: Messages (such as telephone calls or data messages) are automatically forwarded to an individual who is away from his/her home or office based upon information obtained when the individual engages in a transaction or activity, such as making a credit card purchase or credit card call, that indicates his or her location, e.g., at a particular merchant or telephone. Information from the transaction that links the individual and his/her current location is forwarded to a database to update an electronic record indicating the individual's availability, and where the subscriber may be reached. A call thereafter placed to the individual, either using a personal telephone number or the ordinary home or office number, causes the individual's record to be accessed and current location retrieved, so that the message can beautomatically forwarded to that location. In some instances, the caller is furnished with the caller's general location (i.e., area), so that the message can be transmitted via cellular telephone, paging or other wireless communication.

Title: Sheath for endoscope
Inventor: WILLIAMS WILLIAM B III
IPC: A61B1/00
Filed: 1992-06-17
Abstract: The sheath for endoscope includes a tubular sleeve portion and a lens cover portion at one end of the tubular sleeve portion. The lens cover portion is of a predetermined thickness that minimizes light reflection onto the field of view of the endoscope. The sheath thus provides optimum visual acuity when used with the endoscope.      The lens cover portion can include an anti-fogging ingredient to minimize condensation or congregation of fluids during examination. In several embodiments of the invention the sheath is rigid and in other embodiments of the invention the sheath is flexible. In any of the embodiments the lens cover portion can be joined to the inside, outside or end of the tubular sleeve. The lens cover portion can be formed with a cap section that is oriented at a selected predetermined angle with respect to a central axis. The sheath can have one or more reduced diameter sections to prevent relative slippage between the sleeve and the barrel of the endoscope. The sheath can also be incorporated in a cover for covering the entire endoscope. The cover includes a drape portion that covers the main body portion of the endoscope and the sheath is detachably joinable to the drape portion or can be integrally joined thereto.

Abstract: An improved device and method of separating the cellular components of whole blood from plasma or serum and assaying the plasma or serum for a predetermined soluble constituent are disclosed. The device includes a filter pad, that separates the cellular components of whole blood from the serum or plasma, and a test pad, that assays the serum or plasma for a predetermined soluble constituent. The filter pad effectively separates and retains cellular components of the whole blood sample, thereby eliminating assay interference by the cellular components of whole blood. The method includes contacting the whole blood with a test device including a filter pad comprising a suitable carrier matrix homogeneously incorporating therein a separating reagent composition comprising a) separating reagent, like an agglutinin, such as a blood type nonspecific lectin; a coagulant, such as a thrombin or a thrombin-like compound; or a mixture thereof, and b) a nonhemolytic surfactant, like an ethoxylated or propoxylated nonionic or anionic surfactant, such that the cellular components of the whole blood are separated from the plasma or serum as the blood permeates through the filter pad, The essentially cell-free plasma or serum then saturates a test pad that is in contact with the filter pad. After the plasma or serum saturates the test pad, the test pad is examined for a qualitative or quantitative response to a predetermined soluble constituent of the whole blood.

Title: Hydrogen Damage Confirmation with Emats
Inventor: LATIMER PAUL J
IPC: G01N29/04
Filed: 1993-06-01
Abstract: A method and apparatus for use in confirming hydrogen damage in a boiler tube comprises a pair of electromagnetic acoustic transducer coils which are mounted for movement toward and away from each other.  An electromagnet produces pulses that generate acoustic beams across a chord and within the wall thickness of the boiler tube.  For adapting to boiler tubes of different outside diameters, the transducers coils are mounted on a resilient member so that the coils can be pressed against the outer surface of coils having a variety of outside diameters.  The angle of the acoustic beam between the coils must also be adjusted, however, and this is done by changing the frequency of energy applied to the coils.
