Publication number: 20230131595Abstract: Medical delivery system for accessing a tricuspid valve via an inferior vena cava, including an outer guide catheter, an inner guide catheter and an interventional catheter. The first deflection portion of the outer guide catheter is steerable to define a first outer-guide-catheter curve and the second deflection portion of the outer guide catheter is steerable to define a second outer-guide-catheter curve and the first deflection portion of the inner guide catheter is steerable to define a first inner-guide-catheter curve.Type: ApplicationFiled: October 24, 2022Publication date: April 27, 2023Applicant: EVALVE, INC.Inventors: Dylan T. Van Hoven, Michael F. Wei

Patent number: 11590321Abstract: A steerable guide catheter includes a tip ring at a distal end and one or more pullwires configured to engage with the tip ring when put in tension, the pullwire(s) thereby subjecting the steerable guide catheter to a curving or turning force. The tip ring includes a saddle and one or more pullwire channels allowing the pullwire to be looped over the saddle such that when the pullwire is placed under tension, it abuts against the saddle of the tip ring. Some embodiments include additional catheters axially aligned within or outside of the steerable guide catheter, and include a keying feature aligning the rotation of the multiple catheters. The keys of the keying feature can be formed of a polyamide with a glass microsphere filler, and can be thermally welded to the catheter.Type: GrantFiled: July 1, 2019Date of Patent: February 28, 2023Assignee: EVALVE, INC.Inventors: Dylan T. Van Hoven, Jose C. Vital, Amy Lee

Publication number: 20230016654Abstract: A mitral valve clip includes a stud, a lock, and two arms. The stud includes a shank, and the lock includes a frame relative to which the stud is translatable and into which the shank extends. The lock is able to prevent movement of the stud relative to the lock in at least one direction by locking engagement of the shank. The two arms are connected to the lock and the stud such that an angle between the arms depends on a location of the stud relative to the lock. The locking engagement of the shank that prevents movement of the stud relative to the lock in the at least one direction is only possible when the angle between the arms is below a predefined locking threshold.Type: ApplicationFiled: July 7, 2022Publication date: January 19, 2023Applicant: Evalve, Inc.Inventors: Chad J. Abunassar, Jessie A. Garcia, Dylan T. Van Hoven

Patent number: 11504064Abstract: The present disclosure relates to delivery devices and interventional devices configured to enable monitoring of pressure and other hemodynamic properties before, during, and/or after a cardiac procedure. A guide catheter includes a routing lumen or a routing groove for routing a sensor wire to a desired location during a cardiac procedure. A guide catheter includes one or more pressure sensors positioned to provide desired pressure measurements when the guide catheter is deploying an interventional device. An interventional device may also include one or more associated sensors for providing hemodynamic information before, during, and/or after deployment.Type: GrantFiled: July 27, 2017Date of Patent: November 22, 2022Assignee: EVALVE, INC.Inventors: Chad J. Abunassar, Brandon W. Chu, Patricia H. Ho, Koji J. Kizuka, Benjamin L. Lee, Tamer M. Mahmoud, Sean A. McNiven, Scott C. Mosher, Santosh V. Prabhu, Lauren G. Troxler, Dylan T. Van Hoven

Publication number: 20200121894Abstract: The present disclosure describes delivery systems for intravascularly delivering one or more interventional devices to a targeted treatment site within a patient's body. A proximal end of a delivery catheter is coupled to a handle. One or more control lines extend from the handle through the delivery catheter to a coupler disposed at or near the distal end of the delivery catheter. Tensioning of the one or more control lines manipulates the coupler to form or adjust a compound curve in the delivery catheter.Type: ApplicationFiled: December 19, 2019Publication date: April 23, 2020Inventors: Santosh V. Prabhu, Dylan T. Van Hoven, Manish B. Gada

Publication number: 20200060687Abstract: Devices and methods for use in a cardiac valve repair procedure, particularly a tricuspid valve repair procedure. An interventional clip device includes a pair of distal elements rotatably joined to a coupling member, and a pair of proximal elements resiliently biased toward the distal elements to grasp tissue therebetween. The proximal elements include a plurality of adjustable tines moveable between a retracted configuration and an open configuration to avoid damage to tissue prior to engagement while allowing tines to enhance gripping to targeted tissue when open. A delivery system enables delivery of an interventional clip to a targeted cardiac valve, and includes a support structure for maintaining position relative to the cardiac valve.Type: ApplicationFiled: November 4, 2019Publication date: February 27, 2020Applicant: Evalve, Inc.Inventors: Carlos G. Hernández, Laura M. Kalvass, Scott C. Mosher, Santosh V. Prabhu, Paolo Romitelli, Lauren G. Troxler, Dylan T. Van Hoven
