Abstract: A device is in various embodiments configured to repair a native heart valve or to secure a prosthetic heart valve within a native valve of the heart of a patient. Embodiments of the device include at least an upper coil and a lower coil, where the device is configured to assume an axially expanded state where the entire upper coil is positioned on a first side of the lower coil relative to the central axis, and an axially compressed state where at least a portion of the upper coil is positioned on a second side of at least a portion of the lower coil opposite to the first side relative to the central axis.

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.
