Publication number: 20190311478Abstract: The present invention is directed to a system and method for automatic detection, localization, and semantic segmentation of at least one anatomical object in a parameter space of an image generated by an imaging system. The method includes generating the image via the imaging system and providing the image of the anatomical object and surrounding tissue to a processor. Further, the method includes developing and training a parameter space deep learning network comprising convolutional neural networks to automatically detect the anatomical object and the surrounding tissue of the parameter space of the image. The method also includes automatically locating and segmenting, via additional convolutional neural networks, the anatomical object and surrounding tissue of the parameter space of the image. Moreover, the method includes automatically labeling the identified anatomical object and surrounding tissue on the image. Thus, the method also includes displaying the labeled image to a user in real time.Type: ApplicationFiled: June 29, 2017Publication date: October 10, 2019Inventors: Michael R. Avendi, Kenneth C. Hsu, Shane A. Duffy, Dominique J. Fantasia, Steve S. Khalaj, Hasnain Somji, Aimee T. Bui, Shirzad Shahriari, Ambar A. Avila, Joost L. Mulders

Publication number: 20190175872Abstract: The present invention is directed to an echogenic catheter assembly. The catheter assembly includes a catheter having a proximal end and a distal end that defines a lumen extending from the proximal end to the distal end. Further, the catheter assembly includes a coil member configured with at least a portion of the lumen of the catheter. The coil member forms a plurality of outwardly extending projections. One or more of the outwardly extending projections define a cross-sectional shape having at least one non-arcuate edge. As such, the non-arcuate edges of the outwardly extending projections are configured to enhance ultrasonic imaging of the catheter when inserted into a patient.Type: ApplicationFiled: June 23, 2016Publication date: June 13, 2019Inventors: Justin Coker, Steve S.

Publication number: 20180199915Abstract: The present disclosure is directed to an ultrasonic catheter assembly. More specifically, the catheter assembly includes a catheter and one or more piezoelectric or echogenic components. The catheter has a side wall that extends from a proximal end and a distal end that defines a lumen extending from the proximal end to the distal end. Thus, the lumen is configured to deliver a treatment fluid from the proximal end to the distal end. In addition, the piezoelectric component(s) are configured with the side wall of the catheter and/or embedded at least partially within the side wall of the catheter. As such, the piezoelectric component(s) are configured to enhance ultrasonic imaging of the catheter, e.g. when activated by a stimulator assembly.Type: ApplicationFiled: July 21, 2015Publication date: July 19, 2018Inventors: Justin Jeffrey Coker, Kenneth C. Hsu, Paul Jun, Steve S. Khalaj

Publication number: 20180185613Abstract: The present disclosure is directed to an expandable sleeve for a catheter assembly. The expandable sleeve includes a body configured to fit coaxially around an outer diameter of a catheter of the catheter assembly at a transition location between a hub and the catheter. Further, the body of the sleeve includes a length extending from a first end to a second end. As such, the sleeve is expandable between a compressed position and an expanded position so as to prevent the catheter from collapsing along the length of the sleeve. In addition, when in the expanded position, at least a portion of an interior surface of the sleeve contacts an outer diameter of the catheter.Type: ApplicationFiled: June 18, 2015Publication date: July 5, 2018Inventor: Steve S. Khalaj

Publication number: 20180177980Abstract: The present invention is directed to an echogenic member assembly for use with a catheter assembly. The echogenic member assembly includes at least one echogenic member having a cylindrical body extending between a first end and a second end. Thus, the body defines a longitudinal length between the first and second ends. Further, the cylindrical body has an exterior surface extending from the first end to the second end. The exterior surface includes a plurality of discontinuities arranged in a predetermined pattern so as to enhance ultrasonic imaging. In addition, the longitudinal length of the echogenic member is less than a total length of a catheter of the catheter assembly. As such, the echogenic member provides enhanced ultrasonic imaging to the catheter assembly without compromising the inherent flexibility of the catheter.Type: ApplicationFiled: June 18, 2015Publication date: June 28, 2018Inventors: Steve S. Khalaj, Kenneth C. Hsu, BaoTram Nguyen Pham, John Anthony Rotella, Justn Jeffrey Coker, Paul Jun, Kunal Mahendra Amin

Publication number: 20180169383Abstract: The present invention is directed to an echogenic coil member for a catheter assembly and methods of manufacturing same. The catheter assembly includes a catheter having a proximal end and a distal end that defines a lumen extending from the proximal end to the distal end. Thus, the echogenic coil member is configured within the lumen of the catheter. Further, the coil member includes a plurality of outwardly extending projections that contain a plurality of discontinuities. As such, the discontinuities are configured to enhance ultrasonic imaging of the catheter assembly.Type: ApplicationFiled: June 18, 2015Publication date: June 21, 2018Inventors: Steve S.
