  • Patent number: 8795236
    Abstract: The present disclosure describes a cecostomy tube having a head with an opening and a valve. There is a flexible catheter with a lumen having proximal and distal ends, the proximal end of the catheter in fluid communication with the opening in the head, a portion of the catheter extending away from the head to define the distal end. The catheter also has walls defining inside and outside surfaces from the opening defined in the head to the distal end of the catheter. There is a retainer provided on the distal end of the catheter. The retainer can change shape from a first profile or configuration to a second profile where the second profile is larger than the first profile and the second profile is adapted to retain the cecostomy tube in place in a body. The device may be placed in a single, initial surgical operation.

  • Patent number: 8377379
    Abstract: A lateral flow assay device includes a housing, and a test strip disposed within the housing having a membrane with a detection region and a collection region. A sample meter includes a first end for absorption of a test sample, and a storage section that receives and stores at least a component of the test sample. An opening in the housing is sized for insertion of the sample meter into the housing such that the storage section of the sample meter is disposed adjacent the collection region of the membrane. The test sample component is transferable from the storage section to the collection region for subsequent migration to the detection region. An activatable isolation mechanism is provided within the housing and is disposed so as to isolate portions of the sample meter storage section upon activation thereof such that a defined length of the storage section is presented to the collection region of the membrane.

  • Patent number: 8280471
    Abstract: Disclosed are methods and devices for continuous in vivo monitoring of a potential bacterial infection site. Disclosed devices may be utilized to alert patients and/or health care providers to the presence of pathogenic bacteria at an early stage of a hospital acquired infection, thereby providing for earlier intervention. Disclosed methods utilize optical fibers to deliver an excitation signal to an area in which pathogenic bacteria may exist. In the presence of the excitation signal, bacterial pathogens may autofluoresce with a unique spectral signature. Upon generation of a fluorescent emission, an optically detectable emission signal may be transmitted to a detection/analysis device. Analysis of the characteristics of the emission signal produced in response to the excitation signal may be used to determine the presence or concentration of pathogens at the site of inquiry, following which real time information may be transmitted to medical personnel via a wireless transmission system.

  • Publication number: 20120017897
    Abstract: A pressure indicator for cuffed tracheal tubes is provided. This indicator uses an indicator balloon on the proximal end of the inflation lumen and in fluid communication with the tracheal tube cuff. As the pressure in the cuff changes, the balloon will inflate and deflate. An indicator needle rests on the balloon and moves in response to the inflation and deflation of the balloon, thus showing the state of inflation of the cuff.

  • Patent number: 7790471
    Abstract: A diagnostic method and associated test kit for detecting an analyte residing in a test sample is provided. A sample membrane is utilized having a collection region and a detection region, the collection region having a known saturation volume for the intended test sample. A barrier is defined between the collection region and the detection region. The collection region is saturated with the test sample having a volume of less than about 100 microliters so that a known volume of the test sample is contained in the collection region. The barrier is removed from between the collection region and detection region of the membrane and a diluent is supplied to the collection region of the membrane to facilitate flow of the test sample from the collection region to the detection region of the membrane.

    Abstract: A method for fabricating and assessing the quality of printing on substrates used for chemical or biological array testing, and method for ascertaining relative consistency of the deposit reproducibility is described. Generally, the method involves: providing a substrate, providing a solution mixture of a capture moiety and a colorant; depositing an amount of said solution mixture onto said substrate, monitoring the substrate such that the visible indicator colorant manifests in a co-extensive fashion as with the capture moiety on the substrate. In another aspect, the invention relates to a sensor or assay device comprising a physical complex of a number of capture agents and an amount of colorants adhere to least a part of a surface of a substrate.

Disclosed devices may be utilized to alert patients and/or health care providers to the presence of a pathogen at an early stage of a hospital acquired infection, thereby providing for earlier intervention and improved recovery rates from bacterial infection. Disclosed methods utilize implantable devices for location at an in vivo site. The implantable device is held in conjunction with an optical fiber that detects and transmits an optically detectable signal generated in the presence of a pathogen. Upon generation of the emission, the optically detectable emission signal may be transmitted to a portable detection/analysis device. Analysis of the characteristics of the emission signal produced may be used to determine the presence or concentration of pathogens at the site of inquiry, following which real time information may be transmitted to medical personnel, for instance via a wireless transmission system.
