Publication number: 20150327837Abstract: A method of navigating and positioning an endovascular device in a vasculature is disclosed. Initially, a system including an endovascular device and at least one transducer is inserted into the lumen of a patient. An acoustic signal is then transmitted within the lumen. A reflected signal is pre-processed to extract one or more acoustic features. The one or more acoustic features are processed using a computer readable set of rules to produce an output related to guidance of the instrument within a blood vessel or a position of the instrument within the blood vessel.Type: ApplicationFiled: July 29, 2015Publication date: November 19, 2015Applicant: VASONOVA, INC.Inventors: Wenkang QI, Bradley HILL

Publication number: 20150201947Abstract: Apparatus and methods are provided for closing a tubular structure within a patient's body. The apparatus includes a needle including a proximal end including a hub, a distal end including a sharpened distal tip, a lumen having an oblong cross-section extending proximally from the distal end, and defining a longitudinal axis between the proximal and distal ends, and a clip deliverable from the lumen. The clip is compressible between a relaxed state in which a plurality of tines of the clip are shaped to engage and close a tubular structure within a patient's body, and a stressed state in which the tines are compressed to allow the clip to be loaded into the. The apparatus may also include a pusher member for deploying the clip from the distal tip of the needle such that the tines engage and close a tubular structure through which the tubular member is directed.Type: ApplicationFiled: January 27, 2015Publication date: July 23, 2015Inventors: Bradley B.
