Patent number: 11426235Abstract: An electrode loop assembly for a catheter includes a form wire shaped as a loop, an activation wire coupled to the form wire, and a support tube defining a lumen and enclosing the form wire and the activation wire therein. The activation wire is operable to selectively vary a diameter of the loop, and is routed along a radial inner side of the form wire. The support tube extends along a longitudinal axis from a proximal end to a distal end, and has an oblong cross-section having a major axis. The support tube is twisted about the longitudinal axis such that an orientation of the major axis changes along a length of the support tube.Type: GrantFiled: September 15, 2020Date of Patent: August 30, 2022Assignee: ST JUDE MEDICAL CARDIOLOGY DIVISION, INCInventors: Varun Bansal, Troy Tegg

Patent number: 10898686Abstract: Actuators for steerable medical devices are disclosed that not only deflect or steer a portion of a medical device (e.g., a distal portion of a catheter shaft), but also include mechanisms for actively returning the deflected portion of the medical device to an initial configuration (e.g., straight or substantially straight). These active return-to-straight mechanisms may return a catheter shaft from a deflected configuration to a substantially straight configuration throughout a medical procedure, may employ one or more tension members extending along the catheter shaft, and may comprise a gross return actuator and a fine return actuator. For example, the gross return actuator may be configured to partially reverse the deflection of the distal portion of the catheter; and the fine return actuator may be configured to continue reversing the deflection. The gross return actuator may automatically trigger or actuate (mechanically or electromechanically) the fine return actuator.Type: GrantFiled: September 26, 2018Date of Patent: January 26, 2021Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Varun Bansal, Michael Bowers, Troy T.

Patent number: 9440063Abstract: An electrode assembly for neuro-cranial stimulation includes an electrode, a conductive gel, and an adapter including an interior compartment for positioning the electrode relative to the adapter and for receiving and retaining the conductive gel. The conductive gel contacts the electrode along an electrode-gel interface. An orifice at one end of the interior compartment and adjacent to a positioning surface of the adapter for positioning the electrode assembly against a skin surface of a user enables the conductive gel is able to contact the skin surface of the user to define a gel-skin interface, such that a minimum distance between the electrode-gel interface and the gel-skin interface is maintained between 0.25 cm and 1.3 cm. An electrode assembly mounting apparatus is provided for adjustably positioning a plurality of electrode assemblies against target positions on the cranium.Type: GrantFiled: December 30, 2009Date of Patent: September 13, 2016Assignee: RESEARCH FOUNDATION OD THE CITY UNIVERSITY OF NEW YORKInventors: Johnson Ho, Preet Minhas, Marom Bikson, Abhishek Datta, Varun Bansal, Jinal Patel, Dan Steingart, Jorge Vega, Lucas Parra

Publication number: 20150287092Abstract: A user account may have various attributes which define the user personally. The attributes may be applied to product information of other users so the favorite products of various users with similar attributes can be shared automatically. One example method of operation may include identifying user profile attributes of a first user profile, comparing the user profile attributes to other user profile attributes of other user profiles to identify flagged products of interest by each of the other user profiles, comparing the flagged products associated with the other user profile attributes to identify a minimum relevancy threshold between the user profile attributes and the other user profile attributes, and updating a first data feed of the first user profile with the flagged products that are associated with other user profiles attributes which are above the minimum relevancy threshold as compared to a weighted sum of the user profile attributes of the first user profile.Type: ApplicationFiled: April 7, 2015Publication date: October 8, 2015Applicant: FAVORED.BYInventors: Anthony SAMADANI, Varun BANSAL, Ali LANDRY, Michelle LUBA

Patent number: 8965514Abstract: A method includes coupling electrodes to a patient's head and identifying whether any of the electrodes form a functional set, such that a desired therapeutic effect is achieved when the two or more electrodes deliver a total amount of current to the patient regardless of what portion of the total amount of current each respective electrode carries. One or more constant current sources are provided, each having a supply and return terminal, which supply and return equal amounts of current at any given time. The constant current source(s) are coupled to the electrodes in such a manner that each supply terminal and each return terminal is coupled to no more than the electrodes of a single one of the functional sets, if any, or to a single one of the electrodes not included in one of the functional sets.Type: GrantFiled: April 13, 2010Date of Patent: February 24, 2015Assignee: Research Foundation of the City University of New YorkInventors: Marom Bikson, Abhishek Datta, Varun Bansal, Lucas C.
