摘要： Apparatus and methods are described herein for positioning an epicardial anchor device and measuring the load of a tether extending from a prosthetic heart valve and coupled to the epicardial anchor device. In some embodiments, an apparatus includes a handle assembly (444) coupled to an elongate member (445) and a docking member (446) coupled to a distal end of the elongate member. The docking member can be releasably coupled to an epicardial anchor device configured to secure a tether extending from a prosthetic heart valve implanted with a heart at a location on an exterior of a ventricular wall of the heart. A force sensor device (448) is coupled to the handle assembly and can measure a force exerted on the force sensor device. The force is associated with a tension of the tether extending through the elongate member and handle assembly.
摘要翻译：本文描述了用于定位心外膜锚装置并测量从假体心脏瓣膜延伸并联接到心外膜锚定装置的系绳的负载的装置和方法。在一些实施例中，装置包括联接到细长构件（445）的手柄组件（444）和联接到细长构件的远端的对接构件（446）。对接构件可以可释放地联接到心外膜锚定装置，所述心外膜锚定装置构造成将从植入心脏的假体心脏瓣膜延伸的系绳固定在心脏心室壁外部位置处。力传感器装置（448）联接到手柄组件并且可以测量施加在力传感器装置上的力。该力与通过细长构件和手柄组件延伸的系绳的张力相关联。

摘要： Apparatus and methods are described herein for use in the delivery and deployment of a prosthetic mitral valve into a heart. In some embodiments, an apparatus includes a catheter assembly, a valve holding tube and a handle assembly. The valve holding tube is releasably couplable to a proximal end portion of the catheter assembly and to a distal end portion of the handle assembly. The handle assembly includes a housing and a delivery rod. The delivery rod is configured to be actuated to move distally relative to the housing to move a prosthetic heart valve disposed within the valve holding tube out of the valve holding tube and distally within a lumen of the elongate sheath of the catheter assembly. The catheter assembly is configured to be actuated to move proximally relative to the housing such that the prosthetic valve is disposed outside of the lumen of the elongate sheath.

摘要： Apparatus and methods are described herein for use in the delivery of a prosthetic mitral valve. In some embodiments, an apparatus includes an epicardial pad (1639) configured to engage an outside surface of a heart to secure a prosthetic heart valve in position within the heart. The epicardial pad defines a lumen configured to receive therethrough a tether (1619) extending from the prosthetic valve. The epicardial pad is movable between a first configuration in which the epicardial pad has a first outer perimeter and is configured to be disposed within a lumen of a delivery sheath and a second configuration in which the epicardial pad has a second outer perimeter greater than the first outer perimeter. The epicardial pad can be disposed against the outside surface of the heart when in the second configuration to secure the prosthetic valve and tether in a desired position within the heart.

摘要： The invention relates to apparatus and methods for use in the delivery and deployment of a prosthetic mitral valve into a heart via a transatrial approach. The method comprising: inverting an outer frame of a prosthetic mitral valve when the prosthetic mitral valve is in a biased expanded configuration, the prosthetic mitral valve being formed with a shape-memory material; after the inverting, inserting the prosthetic mitral valve into a lumen of a delivery sheath such that the prosthetic mitral valve is moved to a collapsed configuration, while remaining inverted; inserting the delivery sheath through a trans atrial entry site directly into a left atrium of a patient; moving the prosthetic mitral valve distally out of the lumen of the delivery sheath such that the inverted outer frame of the prosthetic mitral valve reverts and the prosthetic mitral valve assumes its biased expanded configuration; and positioning the prosthetic mitral valve within a mitral annulus of the heart. 31151 Atty Docket No. TNDY-035/01 WO 321861-2187 Dispose outer frame of prosthetic mitral 880 valve in inverted configuration Insert prosthetic mitral valve and tether 882 into lumen of delivery sheath Insert catheter through apex of heart and 884 position distal end of the catheter within left ventricle of the heart Insert delivery sheath with valve and tether into left atrium, through a native 886 mitral valve gap and position distal end of delivery sheath within left ventricle of heart Capture distal end portion of tether with 888 snare and pull tether through catheter and out ventricle wall at apex of heart Deploy prosthetic mitral valve into left 890 atrium of heart such that mitral valve reverts and assumes biased expanded configuration Position prosthetic mitral valve in native 892 mitral annulus and secure epicardial pad to apex of heart
