Patent number: 10350003Abstract: Systems, methods, and devices allow percutaneous mapping, orientation and/or ablation in bodily cavities or lumens. Such may include a structure that is percutaneously positionable in a cavity, such as an intra-cardiac cavity of a heart. Transducers carried by the structure are responsive to blood flow. For example, the transducers may sense temperature, temperature being related to convective cooling caused by blood flow. A controller discerns positional information or location, based on signals from the transducers. For example, blood flow may be greater and/or faster proximate a port in cardiac tissue than proximate tissue spaced from the port. Position information may allow precise ablation of selected tissue, for example tissue surround a port in the intra-cardiac cavity.Type: GrantFiled: January 27, 2016Date of Patent: July 16, 2019Assignee: KARDIUM INC.Inventors: Daniel Robert Weinkam, Jeffery Charles Brewster

Patent number: 10327844Abstract: Intra-cardiac voltage data display systems display a plurality of data sets derived at least from intra-cardiac voltage data sampled by an electrode. In some embodiments, at least some of the data sets are derived from a portion of the intra-cardiac voltage data that excludes an excludable portion of the intra-cardiac voltage data having a relationship with an occurrence of a particular cardiac event to facilitate identification of the existence of a transmural lesion in tissue adjacent the electrode. In some embodiments, the particular cardiac event is the occurrence of an R wave in the cardiac cycle, and the excludable portion is a V wave in the cardiac cycle.Type: GrantFiled: April 27, 2017Date of Patent: June 25, 2019Assignee: KARDIUM INC.Inventors: Daniel Robert Weinkam, Daniel Martin Reinders, Darrell Anthony Harrington, Douglas Wayne Goertzen, Michael Hermann Weber

Publication number: 20190174621Abstract: Some aspects of this disclosure generally are related to improving the robustness of a flexible circuit structure, for example, by providing fault-tolerant electrical pathways for flow of electric current through the flexible circuit structure. In some embodiments, such fault tolerance is enhanced by way of a conductive mesh provided between an adjacent pair of resistive elements. Some aspects are related to improved voltage, current, or voltage and current measurement associated with various pairs of adjacent resistive elements at least when the various pairs have differing distances between them.Type: ApplicationFiled: January 29, 2019Publication date: June 6, 2019Inventors: Daniel Robert Weinkam, Shane Fredrick Miller-Tait, Fernando Luis de Souza Lopes

Publication number: 20180242914Abstract: Transducer-based systems and methods may 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 graphical elements and/or between graphical elements can cause activation of the set of transducers associated with the selected elements. Transducer activation characteristics, such as initiation time, activation duration, activation sequence, and energy delivery characteristics, can vary based on numerous factors. Visual characteristics of graphical elements and between graphical elements can change based on an activation-status of the corresponding transducers.Type: ApplicationFiled: April 27, 2018Publication date: August 30, 2018Inventors: Daniel Martin Reinders, Daniel Robert Weinkam, Roxanne Wai Tak Louie, Danai Bisalputra
