Treating dysfunctional cardiac tissue

Medical devices, systems, and methods reduce the distance between two points in tissue, often for treatment of congestive heart failure and often in a minimally invasive manner. An anchor is inserted along an insertion path through a first wall of the heart. An arm of the anchor is deployed and rotationally positioned according to a desired alignment. Application of tension to the anchor may draw the first and second walls of the heart into contact along a desired contour so as to effect a desired change in the geometry of the heart. Additional anchors may be inserted and aligned with the first anchor to close off a portion of a ventricle such that the ventricle is geometrically remodeled and disease progression is reversed, halted, and/or slowed.

Balloon catheter suturing systems, methods, and devices having pledgets

A direct visualization catheter includes an elongate shaft defining a lumen and having a distal end portion and a proximal end portion and a transparent balloon attached to the distal end portion of the shaft. The balloon includes a first layer comprising a thermoset polymer and a plurality of polymeric fibers at least partially embedded in the thermoset polymer and a second layer disposed on the first layer and comprising a hydrogel.

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.

Atrioventricular valve repair using tension
10617522 · 2020-04-14 · ·

A system for repairing an atrioventricular valve of a patient is provided. First and second tissue-engaging elements are configured for implantation at first and second implantation sites of the patient, respectively. First and second flexible longitudinal members are coupled at respective first end portions thereof to the first and the second tissue-engaging elements, respective. Each of the first and the second flexible longitudinal members comprises a braided polyester suture or a plurality of wires that are intertwined to form a rope structure. First and second flexible-longitudinal-member-coupling elements are coupled to respective second end portions of the first and the second flexible longitudinal members. The first and the second flexible-longitudinal-member-coupling elements are configured to be couplable together during an implantation procedure to couple together the first and the second flexible longitudinal elements.

DELIVERY TOOL FOR IMPLANTATION OF SPOOL ASSEMBLY COUPLED TO A HELICAL ANCHOR

Apparatus is provided, including an implant including a tissue-adjusting member including a longitudinal member, and a tissue anchor coupled to the tissue-adjusting member and configured to be anchored into the tissue of the patient. A tissue-coupling element is coupled to the longitudinal member. A delivery tool is reversibly couplable to the implant and is configured to deliver the implant to the tissue of the patient. The delivery tool includes an elongate shaft, a tissue-coupling-element holder coupled to a portion of the elongate shaft, the tissue-coupling-element holder being configured to hold the tissue-coupling element during delivery of the implant to the tissue of the patient, and an actuating element configured to rotate the tissue anchor so as to facilitate anchoring of the tissue anchor into the tissue of the patient while not rotating the tissue-coupling-element holder with respect to the shaft.

DEVICES, SYSTEMS AND METHODS 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. Such anchors can include deformable or collapsible structures upon tensioning of a bridging element in a lateral direction, or segmented tubes that can be adjusted by tightening of one or more tethers extending therethrough. Such anchors can be used as a posterior anchor in a blood vessel in implant systems having a tensioned bridging element extending between the posterior anchor and an anterior anchor deployed at another location within or along the body organ. Methods of deploying such anchors and use of multiple anchors or multiple bridging elements to a single anchor are also provided.

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.

SURGICAL SUTURING DEVICE FOR REPAIR OF TRICUSPID REGURGITATION AND METHODS THEREOF
20200078012 · 2020-03-12 ·

A surgical suturing device is disclosed. The surgical suturing device may include a first or a second tissue gap, a first pair of needles configured to be movable across the first tissue gap, a second pair of needles configured to be movable across the second tissue gap, and a first suture having first and second ends. The surgical suturing device also includes a second suture having first and second ends and a needle actuator which selectively engages either: the first pair of needles to drive them through the first tissue gap and into communication with the first end of the first suture and the first end of the second suture, respectively; or the second pair of needles to drive them through the second tissue gap and into communication with the second end of the first suture and the second end of the second suture.

PAPILLARY MUSCLE APPROXIMATION PADS

A process for treating a heart valve involves delivering first and second working catheters to a ventricle of a heart of a patient using a transcatheter procedure, approximating a first pad associated with the first working catheter to a backside of a first papillary muscle of the ventricle, approximating a second pad associated with the second working catheter to a backside of a second papillary muscle of the ventricle, and manipulating one or more sutures physically coupled to at least one of the first and second pads to decrease a distance between the first and second papillary muscles.

VALVE REPAIR DEVICES AND PROCEDURES

A method for repairing a native valve of a patient during a non-open-heart procedure includes attaching two or more attachment members to the native valve. The method also includes applying a force to the two or more attachment members such that the two or more attachment members cause a cinching effect on at least a portion of the native valve. The method further includes securing the two or more attachment members with one or more anchor members such that the two or more attachment members maintain the cinching effect.
