  • Patent number: 9901671
    Abstract: A method of preventing extravaation of contrast agent during a computed tomography injection. An automatic injector device facilitates ease of accomplishing the method. The method includes establishing the absence of extravaation using an absorbable injectate, such as saline, prior to injecting the contrast agent. The device includes a computerized injector head capable of switching between two injectates without physical human intervention. The device is controlled by a remote operating panel located in a control room that is protected from X-ray radiation. The device includes various software driven safety features that prevent the occurrence of unsafe conditions.

  • Patent number: 8758294
    Abstract: One embodiment provides a method implemented by a powered inflation device to prepare a balloon catheter for use during a medical procedure. In this embodiment, the method includes drawing an amount of medical fluid from a fluid reservoir into the inflation device during a first motorized operation of the inflation device, removing an amount of air from the balloon catheter during a second motorized operation of the inflation device, and injecting the amount of medical fluid from the inflation device into the balloon catheter during a third motorized operation of the inflation device to inflate a balloon located at a distal end of the balloon catheter. The powered inflation device may be a stand-alone device in one embodiment. In one embodiment, the powered inflation device is coupled to an angiographic injector system. When it is coupled to an angiographic injector system, the balloon inflation device and the injector system may be controlled by a common control panel, or console, in one embodiment.

  • Publication number: 20060081031
    Abstract: The present invention presents novel apparatus and methods to address the problem of measuring surface characteristics of a coated medical device. A preferred embodiment of the invention incorporates a processor-controlled transport module to move a test sample at a predetermined velocity profile past a variety of fixtures. The fixtures include a processor-based, feedback-controlled servo mechanism that applies an predetermined normal force on a test sample with selected test surfaces to measure dynamic friction, abrasion resistance and durability of a coating. More generally, the invention can be used to characterize surface and pull or push properties of a wide variety of objects that also include threads, filaments, rods, tubing, wires, extrusions, films and ribbons.
