20120203093 | APPARATUS, SYSTEM AND METHODS FOR PHOTOACOUSTIC DETECTION OF DEEP VEIN THROMBOSIS - Embodiments of the invention provide apparatus, systems and methods for the detection of deep vein thrombosis (DVT) using photoacoustic measurement of hemoglobin in different states of oxgyenation within tissue. One embodiment of a system for DVT detection comprises at least a first and second light source that emit light at first and second wavelengths, an acoustic transducer, a data converter and a processor. The first and second light sources are directed on the patient's skin to produce a photoacoustic signal (PS) correlated to an amount of absorbance of the first and second wavelengths by a target region of tissue beneath the patient's skin. The acoustic transducer detects the PS and transduces it into an electrical signal which is correlated to the PS. The data converter converts the electrical signal into a digital signal which is analyzed by the processor to detect the presence of DVT within the target region. | 08-09-2012 |
20120330773 | INCREASING THE UTILITY OF OPPORTUNISTIC AND TIME CRITICAL GOODS AND SERVICES - Embodiments of the present invention provide a service to goods and/or service providers and consumers in the traditional context of a “first-come, first-served queue” or “class based” queue. A provider presents a listing of one or offerings to consumers to solicit bids for a good or service associated with the offering. After receiving an acceptable bid from a user, the provider provides feedback regarding the bid that indicates the ranking of the user with respect to other bidders in the bidding process. Based on the feedback, the user may submit a modified bid. Following confirmation of a bid by a user, a winning bid is determined and the user is notified. | 12-27-2012 |
20130023815 | SYSTEM AND METHOD FOR BIPHASIC TRANSDERMAL IONTOPHREOTIC DELIVERY OF THERAPEUTIC AGENTS - Various embodiments provide methods and systems for the biphasic iontophoretic transdermal delivery of therapeutic agents. An embodiment of a method for such delivery comprises positioning at least one electrode assembly in electrical communication with a patient's skin. The assembly includes a solution comprising a therapeutic agent which passively diffuses into the skin. A dose of agent is delivered from the assembly into the skin during a first period using a first current having a characteristic e.g., polarity and magnitude, to repel the agent out of the assembly. During a second period, a second current having a characteristic to attract the agent is used to retain the agent in the assembly such that delivery of agent into skin is minimized. A dose of agent may be delivered on demand by an input from the patient. Embodiments may be used for delivery of agents which cause adverse effects from unwanted passive diffusion. | 01-24-2013 |

20140276065 | High Resolution Intravascular Ultrasound Imaging Systems and Methods - Disclosed is a high resolution intravascular ultrasound imaging system including a catheter with a rotatable imaging assembly and an image processor. The image processor in turn features a pulser configured to energize the ultrasound transducer of the rotatable imaging assembly with a multi-frequency ultrasound waveform signal. The image processor further contains a receiver configured to decompose received ultrasound energy as reflected by the target vessel into a plurality of individual subband signals, individually process these signals and reconstitute these signals into a high resolution image of the blood vessel. The IVUS system of the invention may be useful in characterizing cap thickness of vulnerable plaques or other detailed studies of blood vessels. | 09-18-2014 |
