  • Patent number: 10537725
    Abstract: A method for convection-enhanced delivery (CED) of compounds and an apparatus for use with the method are provided. The apparatus, an ultrasound transducer cannula assembly (TCA) apparatus, can be used for the delivery of a compound to a target in the body such as a cells, tissue or organ in a healthy or diseased state. The ultrasound TCA apparatus comprises a transducer cannula assembly (TCA) and an ultrasound system to enhance penetration of molecules in the target. The ultrasound system may be portable and pocket-sized. The inclusion of ultrasound in the apparatus improves the distribution volume of material four to six times over a convection-enhanced delivery system without ultrasound. Since the targeting can be more focused, less compound is needed, thus lowering the potential for harmful effects to the host and host cells.

    Abstract: The present invention relates to ultrasound coupling adapters, ultrasound coupling devices, ultrasound coupling systems, and methods of using the adapters, coupling devices, and coupling systems in various ultrasound applications. In one embodiment, the ultrasound coupling adapter is for coupling an ultrasound transducer to an ultrasound coupling medium. The ultrasound coupling adapter comprises an interface support region for operably interfacing the ultrasound transducer to the ultrasound coupling medium; and an integrated means for (i) rendering the ultrasound coupling adapter inoperable, and/or (ii) preventing operation of the ultrasound transducer by keeping it from being properly coupled with the ultrasound coupling adapter and/or ultrasound coupling medium.

  • Patent number: 10215612
    Abstract: A fluid detector for determining a presence of a fluid within a container, the detector including a sensor assembly with a lens and a sensor element that outputs a first ultrasonic signal in response to an input electrical signal. A generally cylindrical wall extends outwardly from an outer surface of the container and defines a housing with a cylindrical central bore having a base surface. The sensor assembly is coupled to the lens so that the lens focuses the first ultrasonic signal toward the wall. The sensor assembly is positioned such that it receives a second ultrasonic signal from the wall that results from the first ultrasonic signal. The sensor assembly then generates an output electrical signal corresponding to the second ultrasonic signal.
