Patent number: 11883094Abstract: An ablation instrument (e.g., an ablation balloon catheter system) includes an elongate catheter having a housing with a window formed therein. An energy emitter is coupled to the elongate catheter and is configured to deliver ablative energy. A controller is received within the window and is coupled to the energy emitter such that axial movement of the controller within the window is translated to axial movement of the energy emitter and rotation of the controller within the window is translated into rotation of the energy emitter. The instrument includes a motor that is at least partially disposed within the housing of the catheter; a first gear that is operatively connected to and driven by the motor; and a second gear that is coupled to the energy emitter and is driven by the first gear to cause rotation of the energy emitter, while allowing the energy emitter to move axially.Type: GrantFiled: June 10, 2022Date of Patent: January 30, 2024Assignee: CARDIOFOCUS, INC.Inventors: Gerald Melsky, Brian Estabrook, Lincoln Baxter, Sergei Babko-Malyi, Ronald Green, Paul DiCesare

Patent number: 11832878Abstract: The present disclosure relates to ablation instruments and methods of use thereof, in particular to ablation catheters and methods for an automated sweeping ablation element. The automated sweeping ablation element is configured to provide ablative energy to an initial ablation site and move a predetermined number of degrees to one or both sides of the site in an arcuate path using a sweeping motion while still providing the ablative energy. The sweeping movement of the ablation element can be automated via input parameters entered by a user via a graphical user interface or other device (controller).Type: GrantFiled: June 24, 2020Date of Patent: December 5, 2023Assignee: CARDIOFOCUS, INC.Inventors: Gerald Melsky, Brian Estabrook

Patent number: 11484692Abstract: A method for maintaining a balloon of a balloon catheter at a prescribed pressure of between about 0.2 psi and 1 psi comprises the step of: generating a vacuum within a reservoir defined in a burette that is part of a fluid management system that is configured to controllably inflating and deflating the balloon by circulating balloon fill media along a fluid circuit, wherein generating the vacuum results in formation of a pressure differential along the fluid circuit, thereby allowing the balloon to be maintained at the prescribed pressure between about 0.2 psi and about 1 psi.Type: GrantFiled: September 17, 2020Date of Patent: November 1, 2022Assignee: CARDIOFOCUS, INC.Inventors: Sergei Babko-Malyi, Brian Estabrook, Gerald Melsky, Richard Thompson
