Heart Ventricle Remodeling
20180000589 · 2018-01-04 ·

The ventricle of a heart can be reshaped by passing a plurality of catheters from inside the ventricle to outside the ventricle through holes in the ventricle wall. Fluid-tight bags are then delivered through the catheters and expanded outside the ventricle to a diameter that is larger than the holes. A fluid substance is introduced into the bags, and the fluid substance is configured to solidify into solid pads that are also larger than the holes. The solid pads are then pulled towards each other and locked in position in order to reshape the ventricle.

Percutaneous arterial access to position trans-myocardial implant devices and methods

A system for treating a heart includes a catheter that is advanceable into a chamber of the heart and that is repositionable within the chamber between a septal wall and an external wall to enable penetration of the septal and external walls via a needle that is disposed within a lumen of the catheter. A first guidewire is deliverable through the penetration of the septal wall so that a distal end of the first guidewire is disposed within another chamber of the heart. A second guidewire is deliverable through the penetration of the external wall so that a distal end of the second guidewire is disposed externally of the external wall. The first guidewire is connectable to the second guidewire to join or form a path within the chamber that extends between the septal wall and the external wall.

System and method for reshaping heart

The present teachings provide systems, devices, and methods for reshaping the heart and reducing valve regurgitation. A device can be positioned proximate the heart and have a delivery profile and an inflated profile. The device can have a primary cavity and a secondary cavity, and an adhesive inside the secondary cavity. An injectable medium can be injected to the primary cavity of the device. As the primary cavity is filled, the adhesive is forced out of the secondary cavity to adhere the device. The inflated device can exert pressure on the heart, change the shape of a valve annulus, and allow a better coaptation of the valve leaflets.

Braided anchor for mitral valve

A prosthetic heart valve may include a valve portion, a tether connected to the valve portion, and an anchor for connecting the tether to the wall of the heart. The anchor may include a flexible first disc biased toward a first shape that is convex in a first direction and a neck extending from the first disc in a second direction opposite the first direction. The neck has a first end connected to the first disc and a second end. The anchor may further include a flexible second disc connected to the second end of the neck and biased toward a second shape that is convex in the first direction. When deployed, the first and second discs sandwich the wall of the heart.

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.

An epicardial anchor system comprising a tether attachment member defining a portion of a tether passageway configured to receive a portion of a tether extending from a heart valve, a base having a rim defining a void along a circumference of the rim, and a tether capture device adjacent the tether attachment member and hingedly attached to the epicardial anchor, the tether capture device including an opening configured to receive the portion of the tether therethrough and a slot configured to capture the portion of the tether extending through the opening, and an actuation mechanism configured to flip the tether capture device from an unactuated condition to an actuated condition, wherein in the unactuated condition, the tether capture device is spaced from the void defined by the rim, and in the actuated condition, a first portion of the tether capture device is positioned within the void defined by the rim.

STENTS HAVING BRIDGE LENGTH PATTERN VARIATIONS

Disclosed are various embodiments of a stent having a variety of pattern variations defined by a polynomial function, such as a 4.sup.th order polynomial. For example, the pattern variation can include bridges and/or struts forming the stent that have different lengths along a length of the stent. The pattern variations can assist with achieving desired and variable flexibility and conformity to vasculature along the stent.

Cardiac support device delivery tool with release mechanism

An apparatus for placing a cardiac support device (CSD) on a heart. The apparatus includes a body, a deployment mechanism on the body for supporting the CSD in an open position for placement on the heart, and a release mechanism coupled to the deployment mechanism for releasably mounting the CSD to the deployment mechanism. The release mechanism includes a release element for releasably engaging the CSD, and a release actuator coupled to the release element for actuating the release element to release the CSD.

MEDICAL CHAMBER SYSTEM, INTRODUCTION SYSTEM AND KIT
20220031458 · 2022-02-03 ·

The present invention relates to a medical chamber system (700) for implantation in the chest of a patient to support the heart activity, preferably by displacing the heart apex (105), comprising at least a first chamber (702) for arrangement inside the heart sac (300) and a second chamber (701) for arrangement outside the heart sac (300), wherein the chambers (701, 702) comprise at least one connection portion or connection channel (703) which connects the two chambers (701, 702) to each other, the chambers (701, 702) and the connection channel (703) are further embodied to be filled with fluid (705) and, preferably in the implanted state, to be arranged such that the heart activity acts on the first chamber (702) and that the second chamber (701) acts as a volume storage and/or energy storage for the fluid (705). Furthermore, the present invention relates to an introduction system for a medical chamber system (700) and to a kit, encompassing a medical chamber system (700) and an introduction system.
