Leaflet capture and anchor deployment system

Methods and devices for transvascular prosthetic chordae tendinea implantation are disclosed. A catheter is advanced into the left atrium. From an atrium side, a leaflet connector carried by a distal end of the catheter can be anchored to a superior surface of a mitral valve leaflet. A needle is axially advanceable through the leaflet connector and through the leaflet. A leaflet anchor having a leaflet suture can be advanced out of the needle to secure the mitral valve leaflet to the leaflet suture. A ventricular anchor is anchored to the wall of the ventricle to secure the ventricular wall to a ventricle suture. The leaflet suture and the ventricle suture may be tensioned and connected by a suture lock to form an artificial chordae.

Cardiac tissue anchoring devices, methods, and systems for treatment of congestive heart failure and other conditions

A heart tissue gripping device may include a body portion, an elongate shaft, and a tissue gripping member that is attached to the distal end of the elongate shaft. The tissue gripping member being may be positioned adjacent a heart surface by insertion through an incision in the body. The tissue gripping member may releasably attach to tissue of the heart surface to facilitate a surgical instrument in performing one or more procedures. A coupling of the tissue gripping member may releasably attach the surgical device to the tissue gripping member to allow the device to access the tissue of the heart surface.

Method and system for closing left atrial appendage

The present teachings provide methods for resizing, reducing, and/or closing an atrial appendage. A delivery catheter is percutaneously advanced to the atrial appendage. At least two tissue anchors are implanted in tissue of the heart. Both tissue anchors are pulled together so that the atrial appendage is resized, reduced, and/or closed. This closure method and system could be used alone in closing the atrial appendage. This closure method and system could also be used in addition to other treatment mechanisms.

Low profile ribbon frame for valve repair devices

A low profile implant, system and method of deployment includes a frame comprising an elongate body having ends that overlap to form an annular configuration of the frame. A circumference of the frame may be modified by varying an extent of the overlap between the ends of the elongate body. The elongate structure may extend through a sleeve of a number of respective anchor housings of the implant along a first axis, and anchors may be deployed through bores in the anchor housings along a second axis to secure the anchor housings to tissue. The implant may be deployed about and anchored to a valve annulus, and the circumference of the frame, and associated anchored tissue, may be adjusted to reconfigure the valve annulus.

Soft tissue fixing anchor and soft tissue fixing method using the same
11540823 · 2023-01-03 ·

A soft tissue fixing anchor includes: an anchor member which is inserted to the bone cavity interior and prevented from moving in the bone cavity interior by the artificial joint when the artificial joint is implanted; and a suture of which one end portion is fixed to the anchor member and the other end portion is exposed to a bone cavity exterior of the bone so as to be sutured to the soft tissue.

Endoscopic needle assembly

A needle and suture assembly is provided for use with an endoscopic suturing device with a needle holder arm. The needle assembly includes a needle tip and a needle body. The needle tip has a sharp end, a capture groove, a tab groove and a plug portion positioned between the capture groove and the tab groove. The needle body has first and second ends, tip tabs, retainers for removably retaining the needle body relative to the needle holder arm, and a suture opening. The needle tip is fixed relative to the needle body by plastic deformation of the tip tabs into the tab groove. A suture extends into the suture opening of the needle body and is fixed therein.

Method for coupling soft tissue to a bone
11534157 · 2022-12-27 · ·

A method for coupling tissue with a flexible member including a tail and a self-locking construct coupled to the tail. The self-locking construct includes an adjustable first loop and an adjustable second loop coupled thereto. The method includes implanting an anchor in bone, the anchor slidably mounted to the tail. The tail is positioned relative to the tissue. An end of the tail is inserted through the first loop. The tail is passed through the first loop, the second loop is pulled into the anchor, and the self-locking construct is positioned relative to the tissue. The self-locking construct is tightened against the tissue by pulling on an end of the self-locking construct. The first loop is tightened onto the second loop.

Delivery system with anchoring nosecone and method of delivery
11534299 · 2022-12-27 · ·

A delivery device includes an inner shaft, an outer sheath, a nosecone, and a tether component. The outer sheath is slidably disposed over the inner shaft. The nosecone is removably coupled to the inner shaft. The nosecone includes a delivery configuration for delivery to a treatment site, a radially compressed configuration in which a portion of the nosecone is configured to traverse through a heart wall, and a radially expanded configuration in which an outer surface of the nosecone contacts an outer surface of the heart wall. The tether component includes a first end coupled to the nosecone. The nosecone is configured to plug a piercing in the heart wall when in the radially expanded configuration.

Devices and methods for tissue repair

A tissue repair construct having first and second implants coupled via a flexible element is provided. The flexible element forms an adjustable loop closed with a sliding knot, and has first and second free ends extending from the knot formed by wrapping the second end around the first end. The second implant can have a changeable configuration. The construct can be placed within a surgical site in a patient's body such that the first implant is passed into a bone adjacent to soft tissue and the second implant is disposed on an opposed side of the soft tissue. The first free end of the flexible element is configured to be tensioned to decrease a size of the loop and thereby change the configuration of the second implant and to thereby cause at least the second implant to move towards the first implant.
