Patent number: 11642046Abstract: This disclosure relates generally to a system and method for shoulder proprioceptive analysis of the person. The present disclosure monitors the shoulder joint motion by quantitative measure of range of motion (ROM) and kinesthesia of shoulder using a smart watch, thereby assessing the limit of active motion and the ability to passively reposition the arm in space. The present disclosure estimates the ROM, velocity, quality of joint movement, direction of hand movement using the sensor data captured by the smart watch. Further, the present disclosure provides a performance metrics of the shoulder function by comparing the shoulder motion before and after a prosthesis procedure. The present disclosure implements a rule engine-based approach classifying the shoulder/arm movement which includes flexion, extension, abduction, and adduction, internal and external rotation.Type: GrantFiled: October 16, 2020Date of Patent: May 9, 2023Assignee: Tata Consultancy Services LimitedInventors: Srinivasan Jayaraman, Murali Poduval, Joshin Sahadevan, Harshad Chandrakant Kulkarni

Publication number: 20210290175Abstract: Continuous monitoring of subject's cardiac system using biological signal(s) (BS) during day-to-day activities is essential for managing personal cardiac health/disorders, etc. Conventional systems/methods lack in improvising overall classification results and configured for specific device/signal say ECG or PPG and so on. Present disclosure provides systems and methods for classifying BS obtained from users, wherein BS are preprocessed to obtain filtered signals (FS). Corresponding feature extraction module is utilized for feature set extraction based on features in FS. The feature set is reduced and segmented into test and training data. Biological signal classification model(s) are generated using training data and a BCM is applied on test data to classify biological signals (BS) as one of Atrial Fibrillation (AF), a non-AF, a cardiac arrythmia disorder, or ischemia.Type: ApplicationFiled: March 16, 2021Publication date: September 23, 2021Applicant: Tata Consultancy Services LimitedInventors: Srinivasan JAYARAMAN, Joshin SAHADEVAN, Sundeep KHANDELWAL, Ponnuraj KIRTHI PRIYA

Publication number: 20210212626Abstract: Electrocardiogram (ECG) system has been adopted for almost a century to diagnose cardiovascular disease (CVD). Monitoring the cardiac signal provides an insight of CVD and function as an aiding tool for physician towards early detection of cardiac events. A method and wearable device to continuously monitor and determine the cardiac health of the person have been provided. The device is configured to monitor the cardiac system continuously in a partially or fully non-contact manner. The non-contact sensing is achieved by using a hybrid sensing technique. The device consists of a pair of electrodes, one electrode could be a contact sensor that will be touching the skin and the second sensor could be a non-contact sensor. The device facilitates to alert cardiac health monitoring locally or remote location. The device monitors cardiac health in the work environment rather than inducing stress among the participants by making them undergo a stress test.Type: ApplicationFiled: December 11, 2020Publication date: July 15, 2021Applicant: Tata Consultancy Services LimitedInventors: Srinivasan Jayaraman, Raghu Thopenahalli Shanmukhapp, Harshad Kulkarni, Joshin Sahadevan, Praveen Sureshrao Kadni

Patent number: 9877854Abstract: A stent delivery device having a locking mechanism. The device includes a handle assembly, an elongate inner member, and an elongate outer tubular member surrounding the elongate inner member. The handle assembly includes a handle attached to one of the inner member and the outer tubular member, and an actuator attached to the other of the inner member and the outer tubular member. Actuation of the actuator relative to the handle between a first position and a second position causes axial movement of the outer tubular member relative to the inner member. The locking mechanism has a locked position in which the actuator is prevented from moving from the first position to the second position and an unlocked position in which the actuator is permitted to move from the first position to the second position.Type: GrantFiled: May 8, 2015Date of Patent: January 30, 2018Assignee: Boston Scientific Scimed, Inc.Inventors: Doreen Rao, Ronald Ciulla, Joshin Sahadevan, Debasish Sarangi, Rahul Mishra

Patent number: 9622895Abstract: Some embodiments of the present disclosure are directed to a stent loading and delivery device, and methods for making and using the device. The device includes a handle assembly and an outer tubular member extending distally from the handle assembly. A proximal end of the outer tubular member is attached to a first handle of the handle assembly. The device includes an intermediate tubular member slidably disposed within the outer tubular member and an inner elongate member extending distally from the handle assembly within the intermediate tubular member.
