Abstract: A docking device for docking a prosthetic valve at a native valve of a heart includes a coiled body and a high friction sleeve. The coiled body has an upper region, a central region, and a lower region. The docking device is configured to be implanted at the native valve with the upper region positioned in a first chamber of the heart, the lower region positioned in a second chamber of the heart, and the central region positioned to extend around a plurality of leaflets of the native valve. A high friction sleeve covers at least a portion of the central region. The high friction sleeve comprises a material configured to generate more friction between the prosthetic valve and the docking device than an exterior surface of the coiled body.

Abstract: An anchoring system and related methods are provided for treatment of dilated hearts and of functional valve regurgitation, the system comprising one or more self-expandable or manually expandable anchors and associated devices for fixating a valve splint within the heart. For example, a spade-shaped assembly may be configured to be deployed in a right ventricle of the heart and to stabilize a puncturing instrument to puncture the septum. Various puncturing instruments may also be part of the anchoring system, including one or more of a flexible needle having a multiplicity of slits disposed along the length of the needle, a trocar catheter with a retractable head, and a catheter needle having a blunt introducer to protect nearby tissue within the heart during advancing a guidewire. A cutter catheter and puncture location catheter may also be part of the system and be used during treatment.

Abstract: A system is in various embodiments configured to treat a native heart valve, such as to secure a prosthetic heart valve within a native valve. Embodiments of the system include a docking device with different coil portions, such as an upper coil and a lower coil, where the device is configured to assume an axially expanded state and an axially compressed state. In the axially expanded state, the entire upper coil can be positioned on a first side of the lower coil relative to the central axis and/or the entire upper coil and the entire lower coil have a positive pitch relative to each other. In the axially compressed state, at least a portion of the upper coil can be positioned on a second side of at least a portion of the lower coil opposite to the first side relative to the central axis and/or at least a portion of the upper coil has a negative pitch relative to at least a portion of the lower coil.

Abstract: Methods of implanting docking devices for prosthetic valves at a native heart valve include positioning a distal end of a delivery catheter into a first chamber of a heart, advancing a tubular body of a docking device from within the delivery catheter so that the distal end of the tubular body is advanced between native valve leaflets and positioned in a second chamber of the heart. The methods further include inserting a coil into a lumen of the docking device so that the tubular body adopts a configuration, releasing a proximal end of the docking device in the first chamber, inserting a replacement valve in an inner space of the docking device, and radially expanding the replacement valve until there is a retention force between the replacement valve and the docking device to hold the replacement valve in a stable position in the native valve.

Abstract: A delivery apparatus for a prosthetic implant can include an elongate first shaft, a first suture guide coupled to the first shaft, an elongate second shaft, and a second suture guide coupled to the second shaft. The first shaft can extend coaxially through the second shaft and the second suture guide, the first suture guide can be disposed distal to the second suture guide, and the first suture guide and the second suture guide can be configured to be axially movable relative to each other.

Abstract: A delivery apparatus for a medical device implant can include an outer catheter and a flexible delivery catheter. The outer catheter can have an axially extending shaft and a first lumen extending co-axially through the axially extending shaft. The flexible delivery catheter can have an elongate shaft having a flexible section extending along a distal portion of the elongate shaft, and the flexible section of the elongate shaft can be positioned or adjusted between a first, delivery configuration and a second, activated configuration. The delivery catheter can have a pull wire extending co-axially through a second lumen axially extending through the elongate shaft. A distal end of the pull wire can be fixedly secured or attached to the distal end of the elongate shaft.
