Abstract: Catheters include first and second segments that each include a proximal end and a distal end. A first connector of each catheter includes a first portion connected to the distal end of the first segment and a second portion connected to the proximal end of the second segment. The first portion and the second portion are engaged so that the first portion can rotated relative to the second portion about an axis of the first connector. The first segment and the second segment can bend in multiple planes via a rotation of the first portion relative to the second portion about the axis.

Abstract: Techniques of this disclosure relate to delivery devices for use in delivering a prosthesis via percutaneous transcatheter (or transluminal) techniques. Embodiments achieve variable tensile and bending resistance of a transcatheter delivery device, which improves trackability and positioning accuracy of the system while maintaining the tensile characteristics of the transcatheter delivery device required for recapture and deployment of the prosthesis. Other embodiments relate to other components of a transcatheter delivery device that can be torqueable to assist in rotational positioning of the prosthesis. Other embodiments relate to the capsule of the transcatheter delivery device outer sheath member and/or the prosthesis retention member of the transcatheter delivery device that can passively or otherwise rotate about their respective central axis to prevent built-up torque during delivery of a prosthesis. The capsule can include an echogenic marker.

Abstract: The present disclosure provides a catheter including a plurality of a segments, each segment having a stiffener extending along its length. The plurality of segments are interconnected with connectors such that each of the segments can bend in multiple planes via rotation of the connectors.

Abstract: Delivery devices and device elements that provide steering capabilities and methods of steering such delivery devices during the delivery of a stented prosthesis to a target site. Various delivery devices include a shaft assembly having a plurality of lumens through which tension members that compressively retain the stented prosthesis to the shaft assembly are routed. By selectively tensioning one or more tension members, the shaft assembly can be pulled or steered in a desired direction. Various embodiments include one or more steering or stiffening rods that can reinforce the device or counteract any unintended bending or steering of the delivery device.

Abstract: Medical devices for positioning a valve in a subject's body, such as a prosthetic heart valve in a subject's heart, are disclosed. The prosthetic heart valve may include a valve assembly, a frame, and a control arm. The prosthetic heart valve may include a commissural post or multiple commissural posts. The prosthetic heart valve may include a positional marker on a control arm. The prosthetic heart valve may include multiple positional markers on one or more control arms. The positional markers can be shapes, characters, or other symbols. The positional markers may themselves be asymmetric. The positional markers may be placed in an asymmetric location on a control arm. The control arm may be asymmetrically shaped.
