Patent number: 10828095Abstract: A device positionable in a cavity of a bodily organ (e.g., a heart) may discriminate between fluid (e.g., blood) and non-fluid tissue (e.g., wall of heart) to provide information or a mapping indicative of a position and/or orientation of the device in the cavity. Discrimination may be based on flow, or some other characteristic, for example electrical permittivity or force. The device may selectively ablate portions of the non-fluid tissue based on the information or mapping. The device may detect characteristics (e.g., electrical potentials) indicative of whether ablation was successful. The device may include a plurality of transducers, intravascularly guided in an unexpanded configuration and positioned proximate the non-fluid tissue in an expanded configuration. Expansion mechanism may include helical member(s) or inflatable member(s).Type: GrantFiled: October 16, 2017Date of Patent: November 10, 2020Assignee: KARDIUM INC.Inventors: Daniel Gelbart, Douglas Wayne Goertzen, Fernando Luis de Souza Lopes

Patent number: 10799281Abstract: A medical device system may be configured to detect an improper energy transmission configuration therein. The condition may be detected by way of a detection of a condition where an energy-transmitting electrode of the medical device system becomes too close to or becomes in contact with an object resulting in an inability of the electrode to properly transmit energy. For example, if the energy-transmitting electrode is a first electrode configured in its operational state to transmit energy to bodily tissue adjacent the first electrode, but the first electrode is inadvertently contacting a second electrode, such contact may cause at least some energy transmitted by the first electrode to follow an unintended path away from its intended path to the adjacent tissue. Such a condition may be detected based at least upon an analysis of information acquired from a sensing device system.Type: GrantFiled: September 4, 2015Date of Patent: October 13, 2020Assignee: KARDIUM, INC.Inventors: Douglas Wayne Goertzen, Daniel Martin Reinders, Daniel Robert Weinkam

Patent number: 9693832Abstract: Transducer-based systems can be configured to display a graphical representation of a transducer-based device, the graphical representation including graphical elements corresponding to transducers of the transducer-based device, and also including between graphical elements respectively associated with a set of the transducers and respectively associated with a region of space between the transducers of the transducer-based device. Selection of a between graphical element can cause activation of the set of transducers associated with the selected between graphical element. Selection of a plurality of between graphical elements and graphical elements can cause visual display of a corresponding activation path in the graphical representation. Visual characteristics of graphical elements and between graphical elements can change based on an activation-status of the corresponding transducers.Type: GrantFiled: March 11, 2013Date of Patent: July 4, 2017Assignee: Kardium Inc.Inventors: Douglas Wayne Goertzen, Jeffery Charles Brewster, Michael Hermann Weber, Daniel Martin Reinders, Daniel Robert Weinkam
