摘要： 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.
