Publication number: 20230355177Abstract: In neonates or infants, the system identifies Neonatal Abstinence Syndrome (NAS) and in adult patients the system monitors for and identifies withdrawal and/or relapse symptoms. The system can be used for NAS babies in hospitals as well as in the home for adults. The system obtains biosensor or behavioral information about a patient from a wearable device on the patient and makes a determinative recommendation based on algorithm driven calculations and takes appropriate action based on its evaluation. The biosensor and behavioral information are collected by way of a wearable device, high precision cameras, muti pitch microphones over progressive periods of time. When the data is indicative of a need for treatment because the patient is exhibiting symptoms or indicating relapse traits, this information is sent to the system where an AI module further predicts and recommends a delivery of treatment for the patient.Type: ApplicationFiled: April 27, 2023Publication date: November 9, 2023Inventors: Shiva Sharareh, Abel Jimenez, Ariel Garcia, Daryl Chau, Neema Onbirbak

Publication number: 20230148863Abstract: The invention refers to a system for delivering a machine-learning based behavioral intervention for the care of withdraw symptoms such as Neonatal Abstinence Syndrome in neonates. The system obtains biosensor or behavioral information about a patient from a wearable device on the patient and makes a determinative recommendation or takes appropriate action based on its evaluation. The biosensor and behavioral information is collected by way of a wearable device over progressive periods of time. When the data is indicative of a need for treatment because the patient is exhibiting symptoms or indicating relapse traits, this information is sent to the system for evaluation. When the data is indicative of a need for treatment, action is taken in the form of a recommendation or when the device is configured to support direct treatment, direct action can be taken to modify alleviate the patient.Type: ApplicationFiled: November 17, 2021Publication date: May 18, 2023Inventor: Shiva Sharareh

Patent number: 11464485Abstract: A needle assembly for use with an ultrasound imaging system includes a needle having a proximal end and a distal end. The distal end is adapted to be inserted into a patient. The needle assembly also includes a transducer mounted to an exterior surface of the needle at the distal end. Further, the needle assembly includes a flexible printed circuit board mounted on the exterior surface of the needle from the proximal end to the distal end. As such, the flexible printed circuit board electrically connects the transducer to a power source.Type: GrantFiled: December 27, 2018Date of Patent: October 11, 2022Assignee: Avent, Inc.Inventors: Steve S. Khalaj, Marc Comtois, Shirzad Shahriari, Shiva Sharareh, Justin J. Coker

Publication number: 20220273913Abstract: A catheter for mapping and/or ablating a region of the heart includes an intermediate section that is connected to a tip assembly at a preset angle by a flexible preshaped section that is more flexible than the intermediate section. The flexible section may absorb displacement force applied to the tip assembly, such as when the tip assembly encounters uneven tissue surface, without displacing the intermediate section. The flexible section prevents excessive force from being applied to the tip assembly, reducing the risk of any of the following: a) mechanical perforation, b) steam pop, c) burying the tip assembly in the myocardium resulting in high temperatures, low energy delivery, thrombus formation and char formation.Type: ApplicationFiled: May 18, 2022Publication date: September 1, 2022Inventors: Seth J. WORLEY, Shiva SHARAREH

Publication number: 20200029856Abstract: A needle assembly for an ultrasound imaging system includes a needle having a proximal end and a distal end. The distal end is adapted to be inserted into a patient. The needle assembly also includes an optical sensor assembly secured to the distal end of the needle. The optical sensor assembly has a field of vision that includes the distal end of the needle and an environment surrounding the distal end of the needle as the needle is inserted into the patient towards a target site. In addition, the needle assembly includes a controller communicatively coupled to the optical sensor assembly. Thus, the controller is configured to receive and process one or more sensor signals from the optical sensor assembly in real-time.Type: ApplicationFiled: July 26, 2018Publication date: January 30, 2020Inventors: Shiva Sharareh, Thomas D.

Patent number: 9717560Abstract: A system for measuring real-time tissue reflection spectral characteristics during ablation includes a catheter for collecting light reflected from tissue undergoing ablation, a detection component for separating constituent wavelengths of the collected light, a quantification apparatus for generating measured light intensity data of the collected light, and a processor for analyzing the data in relation to time. A method for monitoring formation of steam pop during ablation includes delivering light to tissue, delivering ablative energy to the tissue, measuring the reflectance spectral intensity of the tissue, and observing whether the measured reflectance spectral instensity (MRSI) initially increases in a specified time period followed by a decrease at a specified rate. If the MRSI does not decrease, delivery of ablation energy continues.Type: GrantFiled: June 27, 2016Date of Patent: August 1, 2017Assignee: BIOSENSE WEBSTER, INC.Inventors: Chad Allen Lieber, Ariel Garcia, Shiva Sharareh

Publication number: 20170143420Abstract: A catheter is adapted to ablate tissue and provide lesion qualitative information on a real time basis, having an ablation tip section with a generally omni-directional light diffusion chamber with one openings to allow light energy in the chamber to radiate the tissue and return to the chamber. The chamber is irrigated at a positive pressure differential to continuously flush the opening with fluid. The light energy returning to the chamber from the tissue conveys a tissue parameter, including without limitation, lesion formation, depth of penetration of lesion, cross-sectional area of lesion, formation of char during ablation, recognition of char during ablation, recognition of char from non-charred tissue, formation of coagulum around the ablation site, differentiation of coagulated from non-coagulated blood, differentiation of ablated from healthy tissue, tissue proximity, and recognition of steam formation in the tissue for prevention of steam pop.Type: ApplicationFiled: February 3, 2017Publication date: May 25, 2017Inventors: Shiva Sharareh, Chad Allen Lieber, Jeffrey William Schultz
