Diastolic heart failure treatment
11357629 · 2022-06-14 · ·

A method of treating diastolic heart failure includes implanting a cardiac implant in a heart of a subject diagnosed as suffering from diastolic heart failure. A superior portion of a flexible tether of the cardiac implant is anchored to one or more left-atrial sites of one or more walls of the left atrium. An inferior portion of the flexible tether is anchored to a site of a wall of a mid third of the left ventricle, of a wall of an apical third of the left ventricle, and/or of a papillary muscle of the left ventricle. As a result, the flexible tether reduces a volume of the left atrium during at least a portion of ventricular diastole of each cardiac cycle, thereby enhancing ventricular filling. Other embodiments are also described.

DEVICE, METHOD AND SYSTEM FOR RESHAPING A HEART VALVE ANNULUS

Anchors for securing an implant within a body organ and/or reshaping a body organ are provided herein. Anchors are configured for deployment in a body lumen or vasculature of the patient that are curved or conformable to accommodate anatomy of the patient. The invention provides an implant system having multiple anchors, e.g., one or more posterior anchors in combination with one or more anterior anchors. Methods of deploying such anchors, and use of multiple anchors or multiple bridging elements are also provided.

DEVICE, METHOD AND SYSTEM FOR RESHAPING A HEART VALVE ANNULUS

Delivery systems, methods and associated devices to facilitate delivery and deployment of a heart implant. Such delivery systems and methods of delivery include use of a pair of magnetic catheters, including an anchor delivery catheter carrying an anchor, which can be stacked with or can be axially offset from the magnetic head. Such systems further include use of a puncturing guidewire advanceable through the magnetic head of the anchor delivery catheter to establish access to a chamber of a heart and which is attached to a bridging element such that continued advancement of the guidewire draws a bridging element attached to the first anchor across the chamber of the heart while the bridging element remains covered by the magnetically coupled catheters. Methods and devices herein also allow for cutting and removal of a bridge element of a deployed heart implant.

Device for transcatheterly delivering a band around papillary muscles
11344417 · 2022-05-31 · ·

Embodiments of the present disclosure include a method of transcatheterly delivering a band to encircle multiple papillary muscles in a heart. The method may comprise transcutaneously inserting a catheter into a heart and delivering a first end of a first guidewire to a ventricle in the heart via the catheter. The method may further comprise looping a first end of a first guidewire around a first papillary muscle and a second end of a second guidewire around a second papillary muscle. The first end of the first guidewire and the second end of the second guidewire may be brought out of the body while the first and second guidewires remain looped around the first and second papillary muscles, respectively. The first and second guidewires may be interconnected, and at least one end of the first and second guidewires may be pulled to establish a single loop around the papillary muscles.

DEVICES AND METHODS FOR OCCLUDING OR PROMOTING FLUID FLOW
20230270427 · 2023-08-31 ·

Devices and methods for occluding or promoting fluid flow through openings are disclosed. In one exemplary embodiment an occlusion device is provided having an expandable outer elongate tubular body, a guide member extending from a distal end of the outer body, and a slide tube disposed within the outer body, the proximal portions of the outer body and the slide tube being fixedly mated. The slide tube is configured to slide distally within the outer tubular body when the tubular body is expanded to form wings. A tether can be included as part of the device and it can be used to assist in positioning and locking a location of the device in an opening. Exemplary methods for delivering devices disclosed herein are also provided.

TRANSVALVULAR INTRAANNULAR BAND FOR MITRAL VALVE REPAIR

Mitral valve prolapse and mitral regurgitation can be treating by implanting in the mitral annulus a transvalvular intraannular band. The band has a first end, a first anchoring portion located proximate the first end, a second end, a second anchoring portion located proximate the second end, and a central portion. The central portion is positioned so that it extends transversely across a coaptive edge formed by the closure of the mitral valve leaflets. The band may be implanted via translumenal access or via thoracotomy.

INTERATRIAL SHUNT HAVING PHYSIOLOGIC SENSOR

Interatrial shunts having incorporated physiologic sensors are provided for monitoring and treating cardiovascular syndromes, including heart failure and pulmonary hypertension, in which the one or more sensors are affixed to the shunt to measure a physiologic parameter within the interatrial shunt. The shunt may include an anchor having a first flared region, a second flared region, and a neck region disposed between the first flared region and the second flared region, and a biocompatible covering disposed on the anchor to form a lumen. The one or more sensors may be pivotally coupled to the first flared region such that the one or more sensors may transition between a delivery configuration and a deployed configuration where the sensing surface of the one or more sensors is in fluid communication with the lumen.

HEART VALVE PROSTHESIS APPARATUS

A valve prosthesis apparatus for being implanted into a heart is provided. The valve prosthesis apparatus includes a valve body and a ventricle volume reduction member. The ventricle volume reduction member is fixed to the valve body by a connecting member. The ventricle volume reduction member is arranged by way of forming an isolation cavity for reducing the volume of the ventricle between the ventricle volume reduction member and an inner wall of an apex cordis.

Steerable lesion excluding heart implants for congestive heart failure

Devices, systems, and methods for treating a heart of a patient may make use of one or more implant structures which limit a size of a chamber of the heart, such as by deploying a tensile member to bring a wall of the heart toward (optionally into contact with) a septum of the heart.

Systems and devices for setting an anchor

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.
