Patent number: 11622689Abstract: A method of imaging a tissue region may comprise visualizing lesions over a tissue region via an imaging catheter by viewing the tissue region through a viewing region purged by a fluid and identifying, with a computer, a location of each of the lesions relative to one another over the tissue region. The method may also include registering, with the computer, a unique set of ablation parameters received from a treatment device for lesion generation for each of the lesions and generating, with the computer, a map of the lesions based on the identified locations of the lesions. The method may also include visually displaying the map of the lesions in a common display with a real-time field of view image of a first lesion; and visually displaying the registered unique set of ablation parameters for the first lesion with the real-time field of view image of the first lesion.Type: GrantFiled: October 3, 2016Date of Patent: April 11, 2023Assignee: INTUITIVE SURGICAL OPERATIONS, INC.Inventors: Zachary J. Malchano, Ruey-Feng Peh, Vahid Saadat, Ted J. Cooper, David Miller, Veerappan Swaminathan

Publication number: 20150250382Abstract: In vivo visualization systems are described which facilitate tissue treatment by a user in utilizing real time visualized tissue images with generated three-dimensional models of the tissue region of interest, such as the left atrial chamber of a subject's heart. Directional indicators on the visualized tissue as well as the imaging systems may be utilized while other variations may utilize image rotation or manipulation of visualized tissue regions to facilitate catheter control. Moreover, visualized tissue regions may be combined with imaged tissue regions as well as navigational information to further facilitate tissue treatments.Type: ApplicationFiled: May 18, 2015Publication date: September 10, 2015Inventors: Vahid Saadat, Zachary J. Malchano, Jason Paul Watson, Anthony Jonathan Fileds, Chris Rothe, Bryan Wylie, Veerappan Swaminathan

Patent number: 8333012Abstract: Electrode placement and connection systems are described which allow for the electrical connection and maintenance of one or more electrodes positioned on a substrate which is subjected to a variety of mechanical stresses. Such a system may include an imaging hood having an aperture through which transparent fluid is flowed and one or more electrodes positioned along or about the hood. As the hood is configured between a low-profile and opened configuration, these electrodes may remain electrically coupled despite the mechanical stresses subjected to the electrodes and the connections thereto.Type: GrantFiled: October 8, 2009Date of Patent: December 18, 2012Assignee: Voyage Medical, Inc.Inventors: Chris A. Rothe, Isidro M. Gandionco, Edmund Tam, Vahid Saadat, David Miller, Zachary J. Malchano, Veerappan Swaminathan

Publication number: 20100256629Abstract: Methods and devices for treatment of the ostium are described herein. Examples of such devices include inflatable balloons which have one or more raised pores along a distal portion which act as conduits for providing saline flow from the balloon to facilitate visualization of the contacted tissue as well as providing for a conduction path for energy delivery. The balloon may be configured in various shapes to facilitate contact of the balloon in and against the ostium.Type: ApplicationFiled: April 6, 2010Publication date: October 7, 2010Applicant: Voyage Medical, Inc.Inventors: Bryan WYLIE, Edmund TAM, Gregory SCHMITZ, Isidro M.

Publication number: 20100204561Abstract: Imaging catheters having irrigation capabilities are described herein. Generally, the device may include a first inner membrane which is sealed and serves to position the device within or relative to a lumen. This balloon structure, when filled with fluid, expands and is engaged in direct contact with the tissue. A second (outer) membrane is not completely sealed and instead provides a pathway for delivery of fluid at the treatment site for effecting various treatments. Imaging systems, optionally articulatable, may be positioned within the balloon as well as electrodes positionable upon the balloon may be utilized to facilitate tissue treatments.Type: ApplicationFiled: February 11, 2010Publication date: August 12, 2010Applicant: Voyage Medical, Inc.Inventors: Vahid SAADAT, Zachary J.
