  • Patent number: 10322000
    Abstract: Aspects of the disclosure include sizing catheters and methods for determining the size and other physical parameters of an internal orifice or lumen. Embodiments include a sizing catheter assembly having a handle assembly and a catheter assembly including at least one catheter extending from the handle assembly. The catheter assembly also includes at least two sizers, which can be adjustably spaced from each other. Each of the sizers are configured to conform to respective portions of a lumen of a patient's anatomy. The sizing catheter is configured such that the sizers are configured to specify or determine first and second dimensions of the lumen and also distance between the sizers. The sizers can include valve leaflets or the sizing catheter can include a temporary valve. Additional aspects include software/methods of assessing and determining an appropriate implantable device that can include assessing the biomechanical interaction between the device and the anatomy.

  • Publication number: 20150119692
    Abstract: Maximum and minimum dimensional characteristics of a conduit are determined by imaging a portion of the conduit into which an expandable medical device is to be implanted at appropriate points in the cardiac cycle (or other suitable cycle, such as the respiratory cycle, or at other suitable times). The dimensional characteristics of the conduits within the portion of interest may be evaluated and compared to the maximum and minimum dimensional characteristics of the medical device to be implanted in the conduit to determine whether the medical device is of an appropriate size for properly fitting in the conduit.

  • Publication number: 20140114402
    Abstract: Devices and methods for delivering a sealing element post-implantation of valve prosthesis that functions to occlude or fill gaps present between the valve prosthesis and the native valve tissue, thereby reducing, minimizing, or eliminating leaks there through. In a first method, an injectable material is placed within a native valve sinus to form a sealing element that presses native valve leaflets against an outer surface of a heart valve prosthesis. In a second method, an injectable sealing material or a preformed annular sealing component is positioned between the outer surface or perimeter of a heart valve prosthesis and native heart valve tissue. In a third method, a preformed sealing element or component is placed within a heart valve prosthesis to press the prosthesis against native valve tissue.

  • Publication number: 20050113897
    Abstract: An implantable lead includes a defibrillation electrode and a sensor coupled thereto. The electrode and sensor are positioned along a body of the lead such that, when a fixation element couples the lead to an endocardial surface of a right ventricle, the sensor is located in a high flow region and a portion of the defibrillation electrode is located in proximity to a right ventricular apex.
