MINNIMALLY INVASIVE DEVICE FOR TREATING CHRONIC HEART FAILURE
20220331108 · 2022-10-20 · ·

A device for treating chronic heart failure made of a construct composed of cardiac tissue and a frame supporting the construct. The frame has a plurality of elongated members and the cardiac tissue is attached to the elongated members. The elongated members extend outwardly from a converging region and diverge to provide a distal opening and a space proximal of the distal opening between the elongated members, the space dimensioned to fit over a heart of the patient to treat chronic heart failure.

Location, time, and/or pressure determining devices, systems, and methods for deployment of lesion-excluding heart implants for treatment of cardiac heart failure and other disease states

Devices, systems, and methods for treating a heart of a patient may make use of structures which limit a size of a chamber of the heart, such as by deploying one or more tensile member to bring a wall of the heart and a septum of the heart into contact. A plurality of tension members may help exclude scar tissue and provide a more effective remaining ventricle chamber. The implant may be deployed during beating of the heart, often in a minimally invasive or less-invasive manner. Trauma to the tissues of the heart may be inhibited by selectively approximating tissues while a pressure within the heart is temporarily reduced. Three-dimensional implant locating devices and systems facilitate beneficial heart chamber volumetric shape remodeling.

Cardiac treatment system and method

Devices and methods for providing localized pressure to a region of a patient's heart to improve heart functioning, including: (a) a jacket made of a flexible biocompatible material, the jacket having an open top end that is received around the heart and a bottom portion that is received around the apex of the heart; and (b) at least one inflatable bladder disposed on an interior surface of the jacket, the inflatable bladder having an inelastic outer surface positioned adjacent to the jacket and an elastic inner surface such that inflation of the bladder causes the bladder to deform substantially inwardly to exert localized pressure against a region of the heart.

Manually adjustable device

Devices, systems and methods for altering functioning of a tissue/organ by application of force thereto. In one preferred embodiment, a device for reducing or preventing regurgitation of blood through a valve of a heart is provided. A device may include a main body having a segment adapted to apply force to a surface of tissue/organ; a member that applies counterforce to the force applied by the segment; and an adjuster that is manually operable to change the force applied by the segment. The adjuster can be manually operated before or after anchoring of the device to the tissue/organ.

Method and device for percutaneous left ventricular reconstruction

A method for reducing left ventricular volume, which comprises identifying infarcted tissue during open chest surgery; reducing left ventricle volume while preserving the ventricular apex; and realigning the ventricular apex, such that the realigning step comprises closing the lower or apical portion of said ventricle to achieve appropriate functional contractile geometry of said ventricle in a dyskinetic ventricle of a heart.

Self-adjusting device
11833049 · 2023-12-05 ·

A self-adjusting device configured to be placed in contact with tissue/organ and apply mechanical force to the tissue/organ to achieve an improvement of functioning of the tissue/organ. The self-adjusting capabilities can be carried out by three functional subsystems that can be packaged either in a single, integrated system or in separate modules. A sensing subsystem senses the tissue/organ and sends at least one type of sensing signal characteristic of functioning of the tissue/organ to a controlling subsystem. The controlling subsystem processes the signal with an algorithm to determine if a configuration of the device needs to be changed or a force applied to the tissue/organ needs to be changed. An actuating subsystem can be controlled by the controlling subsystem to affect the configuration/force change when needed. A feedback loop is provided to keep the controlling subsystem up to date as to the state of the actuating subsystem.

An epicardial device for reducing or preventing regurgitation of blood through a valve of a heart includes a main body having a segment adapted to apply force to an epicardial surface of the heart. A member that applies counterforce to the force applied by the segment is also provided. A foundation is configured to be anchored to the epicardial surface of the heart. The foundation includes a surface configured with attachment features. The device further includes a surface configured with mating attachment features configured to attach to the attachment features of the foundation. The mating attachment features and attachment features are separable and reattachable to allow repositioning of at least a portion of the device relative to the foundation.

Native valve repair devices and procedures

A system for implanting a repair device onto a native valve of a natural heart to repairing the native valve of a patient during a non-open-heart procedure. The system includes a surgical delivery instrument, a valve repair device, and a gripper control mechanism. The surgical delivery instrument has at least one lumen. The valve repair device is configured to be delivered through the lumen of the surgical delivery instrument and to be attached to a native valve of a patient. The valve repair device includes a pair of paddles, and at least four gripping members. The paddles are movable between an open position and a closed position, and the paddles and the at least four gripping members are configured to attach to the native valve of a patient. The gripper control mechanism is configured to independently move each of the at least four gripping members.
