Publication number: 20200146656Abstract: Systems and methods for estimating acoustic properties in a region-of-interest in a subject or other object being imaged using a reference frequency method (“RFM”) is described. Using this RFM technique, ultrasound data acquired at a given frequency are normalized by ultrasound data acquired at different frequencies (e.g., adjacent frequencies or otherwise) in order to provide estimations of the acoustic properties (e.g., attenuation coefficient, a backscatter coefficient, or both) that are independent of the ultrasound system used to acquire the underlying data. For instance, the amplitude of each frequency component can be normalized by a different frequency in the power spectrum to cancel out the system-dependent effects. Because the methods described in the present disclosure are system independent, they can be applied to any transducer geometry (e.g., linear or curved arrays) and using any beam pattern (e.g., focused or unfocused).Type: ApplicationFiled: June 22, 2018Publication date: May 14, 2020Inventors: Ping Gong, Pengfei Song, Shigao Chen, Joshua D.

Publication number: 20200146689Abstract: In a system and method for deployment of an implant device, the implant device includes a first loop at its proximal end, and a deployment tool has a second loop attached at its distal end. A release wire slidably disposed within the deployment tool has a distal end extending through the first and second loops to releasably couple the implant device to the deployment tool, and a proximal portion extending from a proximal end of the deployment tool, which is held in a retraction device. The retraction device is operable to hold the proximal end of the deployment tool and to pull the release wire proximally through the deployment tool until the distal end of the release wire is withdrawn from the first and second loops to decouple the implant device from the deployment tool.Type: ApplicationFiled: January 10, 2020Publication date: May 14, 2020Applicant: Inceptus Medical LLCInventors: Martin Shabaz, Claudio Plaza, Richard Quick, Paul Lubock, Brian J.

Publication number: 20200146690Abstract: Aspects of the disclosure include methods, systems and devices for severing and optionally removing at least a portion of heart valve leaflets. Leaflets can be partially removed or entirely removed or otherwise, the leaflets can be severed or splayed in such a way as to avoid coronary blockage, LVOT obstruction, or access challenges in procedures where a prosthetic valve is to be implanted within a previously implanted prosthetic valve. Aspects of the disclosure also relate to numerous devices for and methods of disabling one or more valve ligating devices to provide an unobstructed valve opening so that a prosthetic heart valve can be implanted within the opening. The ligation device(s) is disabled either by removing the ligation device(s) or severing one leaflet so that ligated leaflets can be separated. In some embodiments, the ligation device(s) are severed to disable the ligation device(s).Type: ApplicationFiled: November 13, 2019Publication date: May 14, 2020Applicant: Medtronic, Inc.Inventors: Paul T. Rothstein, Jeffrey D. Sandstrom, Joel Racchini, James R. Keogh, Martin T. Rothman
