Embodiment Construction

[0085] Aspects of the present disclosure generally relate to systems, assemblies, devices, devices and methods for medical treatment and / or treatment of heart disease, including, for example, treatment of dilated / enlarged (including dilated left ventricle), valve Insufficiency (including mitral regurgitation) and other similar heart failure conditions. The systems, assemblies, devices, devices and methods are suitable for transcatheter medical treatments that may not require a full open procedure and may be minimally invasive. Each device or device disclosed herein preferably operates passively, since once placed in the heart, the device requires no active stimulation, mechanical, electrical, or otherwise to function. Implantation of one or more of the devices of the present disclosure operates to assist apposition of heart valve leaflets to improve valve function. Additionally, the devices disclosed herein may be placed with other devices that, or the devices disclosed herei...

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 disposedalong 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.

Description

Background technique [0001] Heart failure can occur when the left ventricle of the heart becomes enlarged and dilated due to one or more of a variety of causes. Initiating causes of heart failure can include chronic hypertension, myocardial infarction, mitral insufficiency, and other dilated cardiomyopathy. In each of these conditions, the heart itself is forced to overwork in order to provide the cardiac output required by the body during various demand states. The result may be an enlarged left ventricle. [0002] A dilated or enlarged heart, and especially a dilated or enlarged left ventricle, may significantly increase tension and stress in the heart wall during diastolic filling and systolic contraction due to further dilation of the heart chambers or get bigger. Previous treatments for heart failure include drug therapy, assistive devices such as pumps, and surgical treatments such as heart transplantation, dynamic cardiomyoplasty, and Batista partial left ventricle r...
